RF Energy Exposure Awareness and Control Information, and
Operational Instructions for FCC Occupational Use Requirements

Before using your mobile two-way radio, read this important RF energy awareness and
control information and operational instructions to ensure compliance with the FCC’s RF
exposure guidelines.

Note This radio is intended for use in occupational/controlled conditions, where users have full

knowledge of their exposure and can exercise control over their exposure to meet FCC
limits. This radio device is NOT authorized for general population, consumer, or any
other use.

This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to
provide communications between two or more users over a distance. It uses radio
frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of
electromagnetic energy. Other forms include, but are not limited to, electric power,
sunlight and x-rays. RF energy, however, should not be confused with these other forms of
electromagnetic energy, which when used improperly can cause biological damage. Very
high levels of x-rays, for example, can damage tissues and genetic material.

Experts in science, engineering, medicine, health and industry work with organizations to
develop standards for exposure to RF energy. These standards provide recommended
levels of RF exposure for both workers and the general public. These recommended RF
exposure levels include substantial margins of protection. All two-way radios marketed in
North America are designed, manufactured and tested to ensure they meet government
established RF exposure levels. In addition, manufacturers also recommend specific
operating instructions to users of two-way radios. These instructions are important
because they inform users about RF energy exposure and provide simple procedures on
how to control it. Please refer to the following web sites for more information on what RF
energy exposure is and how to control your exposure to assure compliance with
established RF exposure limits.

http://www.fcc.gov/oet/rfsafety/rf-faqs.html

http://www.osha.gov/SLTC/radiofrequencyradiation/index.html

Federal Communications Commission Regulations

The FCC rules require manufacturers to comply with the FCC RF energy exposure limits
for mobile two-way radios before they can be marketed in the U.S. When two-way radios
are used as a consequence of employment, the FCC requires users to be fully aware of and
able to control their exposure to meet occupational requirements. Exposure awareness can
be facilitated by the use of a label directing users to specific user awareness information.

Safety Requirements

Your EFJohnson Technologies two-way radio has a RF exposure product label. Also, your
EFJohnson Technologies user manual, or product manual, or separate safety booklet
includes information and operating instructions required to control your RF exposure and
to satisfy compliance requirements.

Compliance with RF Exposure Standards

Your EFJohnson Technologies two-way radio is designed and tested to comply with a
number of national and international standards and guidelines (listed below) regarding
human exposure to radio frequency electromagnetic energy. This radio complies with the
IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment
at duty factors of up to 50% talk and 100% listen and is authorized by the FCC for
occupational use. In terms of measuring RF energy for compliance with the FCC exposure
guidelines, your radio antenna radiates measurable RF energy only while it is transmitting
(during talking), not when it is receiving (listening) or in standby mode.

Your EFJohnson Technologies two-way radio complies with the following RF energy
exposure standards and guidelines:

• United States Federal Communications Commission, Code of Federal Regulations; 47
CFR §§ 2 sub-part J.

• American National Standards Institute (ANSI) / Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992.

• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition.

RF Exposure Compliance and Control Guidelines and Operating
Instructions

To control exposure to yourself and others and ensure compliance with the occupational/
controlled environment exposure limits always adhere to the following procedures.

Guidelines

• User awareness instructions should accompany device when transferred to other users.

• Do not use this device if the operational requirements described herein are not met.

Instructions

Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push
the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting
50% of the time, or less, is important because this radio generates measurable RF energy
exposure only when transmitting (in terms of measuring for standards compliance).

Draft 02 - Sep 1 2015

Safety Requirements

Transmit only when people outside the vehicle are at least the recommended minimum
lateral distance away, as shown in Table 1, from a properly installed according to
installation instructions, externally-mounted antenna.

Note The following table lists the recommended minimum lateral distance for bystanders in an

uncontrolled environment from transmitting types of antennas (i.e., monopoles over a
ground plane, or dipoles) at several different ranges of rated radio power for mobile
radios installed in a vehicle.

Rated Power of Vehicle-Installed
Two-Way Radio

Up to 50 watts 1.0 meter
50-110 watts 1.5 meter

Recommended Minimum Lateral Distance
From Transmitting Antenna

Mobile Antennas

• Install antennas at the center of the roof or the center of the trunk deck taking into
account the bystander exposure conditions of backseat passengers and the
recommended minimum lateral distances in Table 1. These mobile antenna installation
guidelines are limited to metal body motor vehicles or vehicles with appropriate ground
planes. The antenna installation should additionally be in accordance with:

• The requirements of the antenna manufacturer/supplier.

• Instructions in the Radio Installation Manual, including minimum antenna cable

lengths.

• The installation manual should provide specific information of how to install the

antennas to facilitate recommended operating distances to all potentially exposed
persons.

• Use only EFJohnson Technologies-approved supplied antenna or EFJohnson
Technologies-approved replacement antenna. Unauthorized antennas, modifications, or
attachments could damage the radio and may violate FCC regulations. Antennas tested
with EFJohnson Technologies radios are listed below.

Section1Radio Overview

This manual is applicable to the Viking® Mobile radios. The availability of many of the
features is controlled by the model of your radio, factory coding of your radio, installed
options, firmware version, and field programming.

Figure 1.1 Viking Mobile Radio (Lightning Control Head)

Depending on the specific model (and options), the Viking mobile radio operates in the
700/800 (762-870 MHz) frequency range.

Note As of January 2013, the FCC has mandated all UHF/VHF radios shall not allow

wideband (25 kHz) mode. Federal frequencies are not under FCC jurisdiction; therefore,
Federal customers can continue to order wideband in VHF and UHF. This mandate does
not affect 800 MHz and can continue to have wideband after January 1, 2013. This option
shall prevent UHF/VHF radios bought after January 1, 2013 from operating in wideband
mode.

The remote control cable is also available in 6 foot (part number 597-5357-775-01) and 50
foot (part number 597-5357-775-03) lengths, but these must be ordered separately.

2.4.2 Remote Control Head Kit 250-5300-003

This kit includes the material required to add a remote control head to an existing dash­mount or remote-mount configuration. The kit includes:

- Viking Remote control head with mounting bracket.

Due to differing operational requirements, the following items are not included in the kit
and must be ordered separately:

- Microphone - see section 3 for further details

- Remote control cable - order 6 ft., 17 ft. or 50 ft. cable as required

- Remote accessory cable - see below for part numbers

Configurations using two remote control heads require the Dual Remote / Accessory /
Data / Siren cable (part number 597-5357-741).

Configurations using a dash-mount mobile with one remote control head can use the
following remote accessory cables, depending on the application:

- Single Remote / Accessory cable (part number 597-5357-706)

- Single Remote / Accessory / UDDI cable (part number 597-5357-736)

- Single Remote / Accessory / Data / Siren cable (part number 597-5357-716)

2.4.3 Hardware Setup

When shipped, the dual remote-mount configuration consists of a dash-mount radio, a
remote control head, a conversion kit for the second control head, and required cabling.
Upon receipt, the installer must convert the dash-mount mobile radio into a remote-mount
configuration using instructions contained in the installation manual (part number 004­5300-73001) which is supplied with the unit.

In the dual remote control configuration, the EFJohnson noise-cancelling microphone
(part number 589-0016-592) should be used on both control heads. This microphone can
be identified by the small circular metal grill above the hang-up button on the rear of the
microphone. Use of other microphones in this configuration will result in degraded
operational performance.

2.4.4 Master / Slave Programming

In both dual control configurations, either control head can be designated as the Master
and the other as the Slave. The Master control head controls the volume of its internal
speaker and any external speakers that are connected to the radio's eight-pin accessory
connector (see installation manual for connection details).

All Viking mobile radios ship from the factory with the dash-mount control head and any
remote control heads set as Master, so in all dual-control configurations, one control head
must be set as the Slave to ensure correct operation.

Control head addressing is set as follows:

1 Power up the mobile radio
2 Press buttons F3, F4 and F5 at the same time, and release (see Figure 2.15).
3 The display will read “ADDRESS 21” if the control head is configured as the Master,

or “ADDRESS 22” through “ADDRESS 27" if the control head is configured as the
Slave.

4 Rotate the Select knob to select the appropriate address.
5 After a short time-out period, display will read “CYCLE PWR” (Standard Control

Head) or “CYCLE POWER” (Lightning Control Head).

6 Power the radio off and back on, and the configuration will be updated.

2.4.5 Dual Control Operation

2.4.5.1 Programming Dual Remote Control Configurations

The Dual Remote configuration requires special programming to accommodate both
remote control heads in the mobile radio system.

Removal of either control head will affect system performance.

2.4.5.2 Power On / Off

The power switching in dual configurations is such that either control head can switch the
radio on, but both control heads must be off to turn the radio off.

If the power button on both control heads is pressed, then the power button on both control
heads must be pressed again to turn the radio off.

It is therefore recommended to always turn the radio on and off using one control head, to
simplify operation and avoid confusion.

2.4.5.3 Microphone Audio

In the dual remote control configuration, when transmitting from one of the control heads,
it is possible for the push-to-talk (PTT) on the microphone of the second remote head to
also be active. In this case, the voice transmissions of both users will be transmitted,
resulting in a “party line” operation. This is done to allow either control unit access to the
voice channel, and to eliminate the circumstance where one operator may be prevented
from having their transmission heard because the other control head is already
transmitting.

To prevent a second operator from interrupting a transmission already in progress, the user
should look at the transmit indicator on the control head prior to pushing PTT to verify that
the mobile radio is not already transmitting from the other control head.

S ECTION

Section3General Operation

3.1.1 Turning Power ON and Setting Volume

Power is turned ON and OFF by pressing the ON-OFF /Volume knob. The radio goes
through a self test when power is turned ON. When that is successfully completed,
software version, unit ID, zone, then channel are briefly displayed (except when a
conventional analog channel is selected), a tone sounds (if tones are enabled), and the
radio is ready for normal operation. If “ENTER PSWD” (Standard Control Head) or
“Enter Password” (Lightning Control Head) is briefly displayed, refer to the next section.

The radio can be programmed so that one of the following combinations are selected at
power up:

- Last Zone/Last Channel

- Programmed Zone/Last Channel

- Programmed Zone/Programmed Channel

If the Radio Alias feature is enabled, the radio will display the (up-to-ten characters for the
Standard Control Head) and (up-to-sixteen characters for the Lightning Control Head)
Radio alias in place of the Self Test message during startup. Radio alias identifies the
personality file used to program the radio, the service area for which the radio is
programmed, or functional grouping for which the radio is programmed. The Radio ID
alias display will be included with the Radio Info display items in both button/scroll and
menu modes. If disabled, the Radio info menu mode will display a blank line.

General Operation

Note In dual control configurations, the power switch at either control point can be OFF for

power to turn OFF.

3.1.1.1 Setting Volume Level

The relative volume setting can be determined using a reference tone as follows:

• If the key press tones are enabled (see Section 4.6) and if so programmed, a short tone
sounds when an option switch is pressed or the Select switch is pressed or rotated.

• If a conventional channel is selected, take the microphone off-hook and if someone is
talking, voice may be heard. If the MON (Monitor) option switch is programmed (see
Section 5.2), pressing it unsquelches the radio and either voice or background noise is
heard. If a SMARTNET/SmartZone or P25 trunked channel is selected, the radio cannot
be manually unsquelched.

The minimum volume level that the volume control can select can be programmed. This
can be used to prevent missed messages caused by unintentionally turning the volume
down too far. Relative levels of 0-255 can be set in steps of 1 (“0” sets the lowest
minimum volume).

Note This setting is applicable to Viking mobile radios with Viking Remote Control Heads.

3.1.1.2 Unprogrammed Tones

The Viking mobile radio can be programmed so that it will not play a tone in the following
cases:

• Unprogrammed button pressed.

• Unprogrammed toggle switch activated.

• Switched to an unprogrammed channel.

3.1.1.3 Standard and Soft Power Down

To turn power off, press the ON-OFF/Volume knob.

A Soft Power Down feature can be programmed to prevent radio power from being turned
off by accidentally pressing the on-off/volume knob. The display message portion of the
display stops updating. The user is able to receive, transmit, and use function buttons, but
the display message will not change. If the channel is changed the Zone/Channel
indication will update.

The user can power the radio completely down by pressing the option button programmed
for this purpose (F2, F6, or Select button).

channel is changed.

The current mode is indicated by the bar over the zone or channel display. For example,
when the bar is over the zone display, the zone select mode is enabled.

Rotating the Select switch clockwise increases the zone or channel and rotating it
counterclockwise decreases the zone or channel number. A single beep sounds when the
channel is changed (if that option is enabled). After the highest zone or channel is
displayed, wrap-around to the lowest zone or channel occurs and vice versa. If an
unprogrammed channel is selected, “UNPROGRAMD” is displayed and a tone sounds.
The radio may also be programmed so that only programmed channels are selected.

The radio can be programmed so that the bar defaults to either the zone or channel display
when power is turned ON and after a change is made. The delay that occurs before it
returns is programmed for 0-99 seconds. It can also be programmed to remain in the last
selected mode.

3.1.7.2 Direct Channel Select

The direct Channel Select feature is available if the Channel Select option switch or menu
parameter is programmed. This feature allows channels to be directly selected using the
Digital Keypad Microphone. Please note that a Digital Keypad Mic is required for Direct
entry.

For direct selection purposes, channels are numbered sequentially starting with the lowest
zone. Each zone can be programmed with up to 255 channels with up to 2048 channels
total.

Proceed as follows to select channels using this mode:

1 Enable the direct Channel Select mode selecting it via the menu or by pressing the

Channel Select option switch. A single beep sounds when the switch is pressed (if that

3-8 Viking Mobile Radio Operating Manual

option is enabled). The alias and sequential number of the current channel are
alternately displayed.

2 Select the desired channel using the channel select knob or directly enter it using the 0-

9 keys. A single beep sounds when the channel is changed (if that option is enabled). If
using the 0-9 keys, the radio attempts to display the entered number after the third digit
is entered or approximately two seconds after the last key is pressed.

3 To exit this mode and select the entered channel, press the Channel Select switch again.

This mode is also exited automatically without changing the channel after
approximately one minute of no activity.

Other features of this mode are as follows:

Draft 02 - Sep 1 2015

General Operation

• When using the Channel Select knob, wrap-around to the lowest zone/channel occurs

after the last channel in the highest programmed zone is displayed and vice versa. For
example, if Zone 1/Channel 5 is the highest programmed channel, wrap-around occurs
after Zone 1/Channel 16 is displayed if the “Programmed Channels Only On Display” is
not selected. If “Programmed Channels Only on Display” is selected, the wrap around
occurs at Channel 5.

• When an unprogrammed channel is displayed, the sequential channel number and

“UNPROGRAMD” are alternately displayed.

• If an invalid channel number is entered using the 0-9 keys, or the Channel Select option

switch is pressed with “UNPROGRAMD” displayed, an error tone sounds,
“INVALID” is briefly displayed, and the displayed channel does not change.

3.1.8 Setting Squelch Control

The user can program a menu item, soft button item (Lightning Control Head only), or
function button, for squelch adjust. While on a conventional analog channel without
emergency or scan active, the user can select the programmed button or menu item for
squelch adjust. The current squelch setting will show on the display. Using the up and
down navigation buttons, or turning the rotary knob clockwise or counter-clockwise on
the mobile radio, the user can adjust the squelch setting to a desired level from -7 to +7.
Increasing the value towards +7 causes the squelch to open sooner for weaker signals
while decreasing towards -7 has the opposite effects. Pressing the select button will store
the new squelch setting and return the user to the main display.

The squelch level is preset and may not require readjustment. However, if the squelch
threshold needs to be changed on a conventional analog channel, it can be changed in the
same way as though using keypad programming if available (see Section 5.14).

Note The Keypad programming feature is available to Federal Government users only.

3.1.9 Zone Edit

Users can build a virtual zone consisting of channels already present in the radio. They can
add or remove channels from zones while the radio is running, allowing changes to be
made at runtime.

The Zone Edit feature can be programmed. It can be toggled on or off on a per-zone basis.
When enabled, it allows you to copy and delete existing channels from a zone.

Only channels within Zone Edit enabled zones can be selected for editing.

• Zone Edit mode can be entered via button press or the menu.

• A momentary button press performs channel copy.

Viking Mobile Radio Operating Manual 3-9

Draft 02 - Sep 1 2015

General Operation

• A press-and-hold performs channel delete.

To copy a channel:

1 Navigate to the channel and select “channel copy”.
2 Select the destination, first the zone and then the channel.
3 These can be selected by the navigation pad or using direct entry.
4 If the destination channel exists, it is overwritten without warning.

General Operation

CAUTION

!

3.1.11 Operation At Extended Range

When approaching the limits of radio range, the other party may not be able to hear your
transmissions and there may be an increase in background noise when messages are
received. You may still be out of range even though you can hear a message. The reason
for this is that the signal you are receiving is usually transmitted at a higher power level
than the one transmitted by your radio. Communication may be improved by moving to
higher ground or away from shielding objects such as tall buildings or hills.

The radio can be programmed to provide an out-of-range indicator when used on an
EFJohnson Infrastructure system. For more information, please see Section 5.13.4.

3.1.12 Preventing Vehicle Battery Discharge

In the standby mode (power on, not transmitting), radio power consumption is relatively
low. Therefore, you can probably leave the radio ON for one or two days without
operating the vehicle and the battery should not become seriously discharged. However, if
the outdoor temperature is low enough to significantly decrease battery capacity, the radio
should be turned OFF when not in use. Also if display is on “high” and you are receiving
calls, the battery charge can drain in less than a day.

Since power consumption is significantly higher when transmitting, it is good practice to
have the vehicle running while transmitting. This ensures that optimum power is being
delivered to the radio and that the battery does not become discharged.

3.1.13 Cleaning the Control Head

The radio Control Head requires periodic cleaning, depending upon the operating
environment.

You will need a soft brush of a size that can access all exposed areas of the Control Head.
You will also need a vacuum cleaner that is portable enough to easily access the Control
Head.

To clean the Control Head:

1 Use the brush to remove the bulk of sand and dust from the Control Head.

Ensure that this is done in an environment that does not allow other equipment to be
affected by the removed sand and dust. If necessary, use the vacuum to collect material as
it is removed.

Viking Mobile Radio Operating Manual 3-11

Draft 02 - Sep 1 2015

General Operation

2 When the bulk of sand and dust is removed, use the brush to clean the interface joint

between the buttons and Control Head plastic.

3 Position the vacuum nozzle two inches (or more, as required) from the face of the

Control Head. Use the brush to remove any remaining sand and dust.

4 Repeat this procedure until the Control Head is completely clean.

3.1.14 Radio Service

If “UNPROGRAMD” is displayed, the cause can be any of the following:

• An unprogrammed channel is selected. Select a programmed channel.

• The selected channel is programmed for an option that is not installed or an error in
programming was detected. Contact your system operator for service.

If the channel is programmed for a system type not programmed, “DISABLED” is
displayed.

If no characters or all characters appear in the display, the viewing angle may be
improperly adjusted. If some other problem is occurring, turn power OFF and then ON
again to reset the control logic. Also make sure that the controls are properly set and that
the power, external speaker, and accessory cables (if used) are securely plugged into the
back of the radio.

If the radio is completely inoperative, check the Main power and ignition sense line fuse.
If it is blown, remedy the cause if possible and replace it with the same type (1A, 15A). If
the radio still does not operate properly, return it to your system operator for service.

Note There are no user-serviceable components in the radio. Altering internal adjustments can

cause illegal emissions, void the warranty, and result in improper operation that can
seriously damage the radio.

Note If the vehicle itself needs to be jump started, the mobile fuses must be pulled before jump

starting to prevent damage to the radio!

3.2 Single Touch

The Single Touch feature allows a Viking radio user to send a predefined Status, Message,
Call Alert, Unit Call, or Interconnect Call by pressing and holding a button. For each
system, up to four buttons in Armada can be programmed for Single Touch. The Single
Touch feature allows a user to bypass the menu and PTT to send a Status, Message, Call
Alert, Unit Call, or Interconnect Call. A maximum of four buttons are programmable to

General Operation

3.3 Radio Inhibit

The radio can receive inhibit commands over the air or through the side port. When the
radio receives an inhibit command the screen goes blank, audio stops, lights turn off, and
most of the controls are disabled. The radio is (from the user’s perspective) frozen. Behind
the scenes, however, the radio is still running. It is waiting for an uninhibit command. If it
receives an uninhibit command, the radio User Interface is enabled and the radio will
operate normally. The general idea behind the feature is fairly simple but there are
exceptions.

• Smartport cannot be used to uninhibit a radio. (Unless an “Allow Uninhibit with RSD”
security policy is on the radio)

• If the radio is rebooted while inhibited, the radio is forced to power up on the channel it
was inhibited on.

• When powering up while inhibited, the backlight and LED will not come on.

• When powering down while inhibited, the display will not display “Powering Down”.

• In conventional mode, the radio waits until the inhibit/uninhibit acknowledgement is
sent before becoming inhibited/uninhibited. This is important mainly for uninhibit
where a race condition existed between the ack being sent and rebooting. If the radio
cannot send the ack, the system will need to retry the inhibit/uninhibit command.

3.4 Setting Squelch

The user can program a menu item, soft button (Lightning Control Head only), or function
button, for squelch adjust. While on a conventional analog channel without emergency or
scan active, the user can select the programmed button or menu item for squelch adjust.
The current squelch setting will show on the display. Using the up and down button on the
Navigation Pad (Lightning Control Head Only) or rotating the select knob on the mobile
radio, the user can adjust the squelch setting to a desired level from -7 to +7. Increasing the
value towards +7 causes the squelch to open sooner for weaker signals while decreasing
towards -7 has the opposite effects. Pressing the select button will store the new squelch
setting and return the user to the main display.

The squelch level is preset and may not require readjustment. However, if the squelch
threshold needs to be changed on a conventional analog channel, it can be changed in the
same way as though using keypad programming if available. The squelch level is preset
during alignment. If the keypad programming feature is available (see Section 5.14), the
squelch threshold can be changed by the user on each conventional analog channel.

Note The Keypad Programming feature is available to Federal Government users only.

3-20 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

3.5 Operating Modes

Each selectable channel can be programmed for the conventional (analog or Project 25
digital), SMARTNET/SmartZone, or Project 25 digital trunking operating mode. For
example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a
SMARTNET channel, and so on. More information on these modes follows.

Note All operating modes utilize certain functions that are activated/deactivated by pressing

and holding a particular button or switch. The “hold” interval is preset. When instructed
to “press and hold”, do so until the desired action occurs or a tone sounds indicating the
option is activated. For other operations (not specified “press and hold”) on ly momentary
pressing is required.

3.5.1 Conventional Mode

This is a non-trunked operating mode which accesses independent radio channels. There is
no automatic access to several channels. Selecting a conventional channel selects a
transmit and receive frequency and other channel parameters such as squelch control
coding.

General Operation

Conventional channels can be either standard (analog), Project 25 (digital), or mix mode.
With digital operation, the DSP (Digital Signal Processor) converts the audio signal to
digital data packets. Another difference is that analog channels use Call Guard (CTCSS/
DCS) squelch control and Project 25 channels use a NAC (Network Access Code) and
talkgroup ID codes.

With Project 25 operation, a NAC is transmitted which must match the NAC programmed
in the repeater or base station equipment and the radio(s) being called for communication
to occur. In addition, to receive standard group calls, the receiving radio must be
programmed to detect the transmitted talkgroup ID code.

With conventional operation, a busy channel condition is detected automatically if the
busy channel lockout (transmit disable on busy) feature is programmed. Otherwise, it must
be detected manually. If the Out of Range indicators are not programmed, an out-of-range
condition is not indicated by special tones or messages as with trunking operation because
there is no initial data exchange with the repeater that allows this condition to be detected.
(For more information about Out of Range indicators, please see Section 3.1.11.)
Operating features unique to conventional channels are described in Section 5.

Viking Mobile Radio Operating Manual 3-21

Draft 02 - Sep 1 2015

General Operation

3.5.2 SMARTNET / SmartZone Mode

This is a trunked operating mode in which automatic access is provided to several RF
channels. ID codes are used to select what radios are being called and what calls are
received. Monitoring is performed automatically and special messages and tones indicate
busy and out-of-range conditions.

SMARTNET and SmartZone operation and programming is very similar. Basically,
SMARTNET operation is limited to a single repeater site and SmartZone operation allows
automatic roaming between sites. SMARTNET/SmartZone features include roaming
(SmartZone only), telephone, unit, emergency calls, Call Alert
analog or digital signaling may be used. Enhanced SMARTNET/SmartZone features
provide the same, plus gives you responses from the system. For example, if the ID you
are calling is turned OFF, the system will display “NOT AVAILABLE”.

When a SMARTNET or SmartZone channel is selected or the radio is powered up on one
of those channels, it searches for a control channel. While searching, the alias (name) of
the selected channel is displayed and the radio attempts to register on the trunked system.
If a control channel could not be found (because of an out of range condition or the system
ID is not correct, for example), “NO SYS” (early units) or “OUT OF RNG” (later units) is
displayed and the radio continues to search for a control channel.

™

, and messaging. Either

The control channel transmits and receives system information to and from all radios
registered on the system. Therefore, once a control channel is found, it is continuously
monitored for incoming call information and is used to make call requests. When the radio
is keyed, a channel grant request is sent through the control channel. The system then
informs the requesting radio what traffic channel to use, through the control channel. Once
the request is granted by the system, the radio moves to the designated traffic channel for
the actual talkgroup call. Once the transmission has ended, the radio returns to the control
channel.

Operating features unique to SMARTNET/SmartZone channels are described in Section 6.

3.5.3 P25 Trunking Mode

The P25 Trunking operating features are very similar to the SmartZone type just
described. Since SmartZone features are also similar to SMARTNET features, all three
modes are described in Section 6. Some differences between the P25 Trunking and
SmartZone modes are as follows:

• Digital signaling is always used with P25 calls. Either analog or digital signaling may be
used for SmartZone calls.

• Calls made to a specific radio in the P25 mode are called Unit Calls. In the
SMARTNET/SmartZone mode they are also called Unit Calls.

• Telephone calls are available in this mode.

3-22 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

General Operation

• The P25 control channel data rate is 9600 baud and the digital voice data rate is also
9600 baud. With SmartZone operation, the control channel data rate is 3600 baud (both
digital and analog calls) and the narrowband digital voice data rate is 9600 baud.

• The P25 mode uses a system ID, Wide Area Communications Network (WACN) ID,
and RF Subsystem ID (RFSS). The SmartZone mode does not use the WACN and
RFSS IDs.

• P25 Unit IDs can be 1-16,777,211 (000001-FFFFFB hex) and SmartZone Unit IDs can
be 1-65,534 (0001-FFFE hex).

3.5.4 Systems, Channels, and Zones

A zone and channel are selected to place and receive calls. The following describes the
relationship between systems, channels, and zones.

3.5.4.1 Systems

A system is a collection of channels or talkgroups belonging to the same repeater site. It
defines all the parameters and protocol information required to access a site. Up to 255
systems of any type can be programmed depending on the option enabled.

The maximum number of channels assignable to a system is limited to 2048. Channels
may also be limited by radio limitations, programmed options, and/or available memory
space as described in the following information.

3.5.4.2 Channels

A channel selects a radio (RF) channel or talkgroup as follows:

Conventional Analog Mode - A channel selects a specific radio channel, Call Guard
(CTCSS/DCS) squelch coding, and other parameters unique to that channel.

Conventional Project 25 Mode - A channel selects a specific radio channel, NAC
squelch coding, talkgroup ID, and other parameters unique to that channel.

SMARTNET/SmartZone and Trunked Project 25 Modes - A channel selects a
specific talkgroup/announcement group, emergency group, and other parameters
unique to that talkgroup.

A maximum of up to 2048 channels can be programmed with the preceding modes
depending on the option enabled. These channels can belong to a single system or multiple
systems.

Draft 02 - Sep 1 2015

General Operation

3.5.4.3 Zones

A zone is a collection of up to 255 channels of any type. For example, a zone could include
12 conventional channels and four P25 Trunking channels. One use of zones may be to
program the channels used for operation in different geographical areas. The maximum
number of zones is 255.

Standard Control Head <F2> performs as the “Left” button, and <F3> performs as the

“Right” button.

To exit menu mode, press <F6>.

4.3 Time-Out Timer

The time-out timer disables the transmitter if it is keyed for longer than the programmed
time. It can be programmed on each channel for times of 15 seconds to 3 minutes, 45
seconds or it can be disabled.

Radio Wide Features

If the transmitter is keyed continuously for longer than the programmed time, the
transmitter is disabled, a continuous tone sounds, and “TX TIMEOUT” is displayed. Five
seconds before time-out occurs, a warning beep sounds to indicate that time-out is
approaching. The timer and tone are reset by releasing the PTT switch.

A different time can be programmed for each system, and the timer can be enabled or
disabled on each conventional channel. With conventional channels, a penalty time can
also be programmed that prevents further transmissions for a certain time after the
transmitter is disabled (see Section 5.5).

One use of this feature is to prevent a channel from being kept busy for an extended period
by an accidentally keyed transmitter. It can also prevent possible transmitter damage
caused by transmitting for an excessively long period.

4.4 Home Channel Select

If the HOME option switch is programmed, pressing it selects the preprogrammed home
channel. This provides a quick way of returning to a frequently used channel. Pressing and
holding this switch until a tone sounds makes the currently selected channel the new
Home. A secondary Home, Home2, may also be programmed.

Note The radio can be optionally programmed so that Pressing and holding the Home option

switch causes the radio to switch to the existing Home or Home 2 instead of making the
current selection the new Home.

Viking Mobile Radio Operating Manual 4-5

Draft 02 - Sep 1 2015

Radio Wide Features

Home Zone and Home Channel cannot be set to “Selected” simultaneously. The same
applies for Home Zone 2 and Home Channel 2. If Home or Home 2 is set to “Selected,”
then Home Channel or Home Channel 2, respectively, will populate with channels 1 to

256.

4.5 Power Output Select

Each conventional channel, SMARTNET/SmartZone, and P25 Trunking system can be
programmed for High, Low, or Switchable transmit power. If Switchable power is
programmed on the channel or system, the Hi/Lo Power option switch can then be used to
select high or low transmitter power. All models support switchable power. The low
power level is typically 15 watts and the rated power output level of the radio at the high
power level is typically 25 - 30 watts, depending on frequency band.

Pressing the Hi/Lo Power switch toggles the power setting. The new level is flashed in the
display when this switch is pressed as “HI POWER” or “LOW POWER”. If selectable
power is not permitted on the current channel or system, the fixed power level is flashed
and no power change occurs. The selected power level is permanent until it is manually
changed again. The power levels are set at the factory or when the radio is tuned using the
Viking Tune™ software.

4.6 Alert Tone Select

The various alert tones that sound are described in Section 9.1. These tones can be enabled
and disabled if the TONE option switch is programmed. To turn all tones OFF, press this
switch and “TONE OFF” is displayed. Then to turn all tones on again, press it and “TONE
ON” is displayed. If this switch is not programmed, tones are fixed in the ON or OFF
condition by programming. Alert tones can be disabled depending on programming. If the
Surveillance mode is programmed (see following), tones are totally disabled.

The Alert Tone volume can be adjusted relative to the volume control setting. This is done
by programming and also by the user if the Alert Tone Volume option switch is
programmed. Relative levels of –170 to +170 can be set with “0” the default setting. The
range is divided into the number of volume ticks set in “Volume Ticks”. For example, if
“Volume Ticks” is 10, the tone adjustment on the radio will go from 1 to 10. A minus
value decreases the tone volume and a plus value increases it. The user adjusted level
permanently overrides the programmed level if applicable.

4.7 Ignition Power Down Duration

The radio can be installed so that the vehicle ignition switch as well as the front panel
power switch of the radio control power. This is done by connecting the accessory cable

ignition switch input to the vehicle ignition switch. Refer to the Viking Mobile Radio
Installation Manual for more information. A Power Down Duration of up to 1,440

minutes can then be programmed, or this feature can be disabled by programming
“Infinite” delay so that there is no automatic power-off.

Both the ignition switch and the power switch must then be on for radio power to turn on.
The delay can be overridden at any time by turning power OFF using the front panel
power switch or turning the ignition switch back ON.

This power down delay can allow calls to be received or the horn alert to be active for a
time after the ignition switch is turned OFF. At the same time, advantages of ignition
switch control are used such as preventing the battery discharge that may occur if the radio
is left ON for an extended period.

Radio Wide Features

4.8 Horn Alert

The horn alert feature sounds an external alert such as the vehicle horn when certain calls
are received. It is available if a Horn option switch is programmed and the proper
connection has been made to the external alert. The horn alert output is pin 4 of the
accessory cable, and an external driver circuit of some type is usually required. Refer to

the Viking Mobile Radio Installation Guide for more information on how to install this

feature.

Additional information on the horn alert feature follows:

• It activates when receiving any Unit Call or Call Alert in the P25 conventional,
SMARTNET/SmartZone, and P25 Trunking modes. It does not sound when receiving
standard Group or telephone calls, and is not programmable on a per call basis.

• It must be manually enabled and disabled by the Horn option switch. It is not controlled
by the vehicle ignition switch. When it is enabled, “HORN ON” is briefly displayed,
and when it is disabled, “HORN OFF” is briefly displayed. It defaults to the OFF mode
whenever power is turned on.

• If a power down duration is programmed as just described, it is functional during that
delay.

• When activated, it can be programmed to sound for three 1-second beeps or
continuously for 2 to 255 seconds. It then turns OFF until another Unit call or Call alert
is received.

Viking Mobile Radio Operating Manual 4-7

Radio Wide Features

4.9 Microphone Off-Hook Detect

The microphone hanger can be connected to chassis ground and the radio programmed to
detect an off-hook condition (Hangup Box Monitor selected). The following operation
then occurs when the microphone is taken off-hook:

Conventional Channel Selected - Scanning temporarily halts (if applicable) and the
Monitor Mode described in Section 5.2 is enabled. However, the receiver unsquelches
only if a carrier is detected.

SMARTNET/SmartZone/P25 Trunking Channel Selected - Scanning temporarily
halts if applicable.

If the off-hook condition is not detected (Hangup Box Monitor not selected), the
microphone hook state has no affect on radio operation.

4.10 Surveillance Mode

If the Surveillance mode is programmed, the backlight, all alert tones, and front panel
LED indicator can be disabled individually or totally, based on programming.

The transmit/receive LED indicator, display and keypad backlight, and all alert tones can
be disabled. When setting is enabled, the radio will power up in Surveillance mode with
the selected options active. A function button can also be assigned which will activate and
deactivate surveillance mode at the user’s discretion. It overrides any other programming
of these functions such as a Tone or Backlight option switch.

This feature can be turned ON and OFF by the user via menu selection or by the
Surveillance Mode option button (if programmed). The user selected mode permanently
overrides the programmed mode if applicable.

4.11 Public Address

This feature allows a single microphone to be used for either radio or public address. An
external public address system can be connected to the radio accessory pigtail cable.
External PA function without a siren controller is provided for cases when the siren
function is not required. This is a low level output, so some type of PA amplifier is
required. The Mic To PA option button (or menu selection) controls this feature.

4-8 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

In the public address mode, microphone audio is always routed to the PA system, and the
radio can be programmed so that receive audio is also routed. When the PA is enabled/
disabled, “EXT PA ON/OFF” is displayed momentarily. The radio can also be
programmed to display “EXT PA ON” continuously. A button/menu function also allows
the user to turn the “Receive Audio to External PA” function on and off.

The cable, Part No. 597-5357-716.01 (Single Remote Control Head) or 597-5357-741.01
(Dual Remote) allows the radio to directly interface with a Federal Signal Omega 90
external PA amplifier without an intervening siren control box. For the mute indication to
be sent to correctly to the amplifier, the radio Aux B output must be configured for “Ext
PA Mute Inv”. This setting provides a mute signal on Aux B just like the existing “Ext PA
Mute” setting, only with opposite polarity as required by the amplifier.

4.12 Scanning

Radio Wide Features

Scanning monitors the channels in the scan list for traffic the radio is programmed to
receive. When traffic is detected, scanning stops and the message is received. Shortly after
traffic is complete, scanning resumes.

The user can enter the scan list edit mode for the selected scan list while the radio is
scanning without manually turning scan off. If the user presses the scan edit button while
the radio is scanning, the radio shall stop scan and enter directly into scan list edit mode
for the selected scan list. The scan edit mode shall timeout after seven seconds of
inactivity. If the scan edit mode times out, or the user exits the mode via the exit button or
the scan list edit function button, the radio shall save the changes to the scan list and restart
scan.

If the microphone off-hook condition is detected (Hangup Box Monitor selected by
programming), scanning stops and selective squelch (such as Call Guard CTCSS or NAC/
group ID detect) is disabled on conventional channels. If the microphone off-hook
condition is not detected (Hangup Box Monitor is not programmed), taking the
microphone off-hook has no affect on radio operation. When a call is received in the scan
mode, the alias of the channel on which a call is received (and any other display
parameters that may be programmed) are displayed until scanning resumes. The selected
channel alias is then displayed if applicable.

There are two scan modes available: Priority (standard) and Radio Wide. The operation of
the priority type is unique to the system type programmed on the selected channel, and the
operation of the Radio Wide type is the same regardless of the system type programmed
on the selected channel. Only one type of scanning can be enabled at a time. For example,
if priority scanning is enabled and Radio Wide Scan is enabled, priority scanning is
automatically disabled and vice versa. Refer to the following for more information.

Radio Wide Features

Scan Enable Indicator

4.12.1 Priority (Standard) Scanning

Priority scanning (also referred to as standard scanning) monitors only channels that are
the same type as that currently selected. For example, if a conventional channel is selected,
only conventional channels are scanned and likewise for SMARTNET/SmartZone and
Project 25 trunking channels.

For more information on scanning functions in the Conventional mode, refer to Section

5.10, and for more information on how it functions in the other modes, refer to Section

6.11. Scanning is turned ON and OFF by menu selection or (if programmed) by the Scan
option switch as follows.

• To turn priority scanning on, press the Scan option switch (or select via menu).
Scanning is enabled when a rotating is indicated in the right status display (Standard
Control Head) or is displayed in the top middle of the display (Lightning Control
Head)

• To turn scanning OFF, press the SCAN option switch again. Scanning is disabled when
“SCAN OFF” is briefly displayed and (Standard Control Head) or (Lightning
Control Head) is no longer indicated in the status display.

• If the zone or channel is changed while scanning is selected, scanning continues on the
same or a different scan list (see Section 4.13.1).

Note Each Conventional, SMARTNET/SmartZone and P25 trunked channel can be

programmed so that scanning is automatically enabled when the channel is selected.

4.12.2 Radio Wide Scanning

Radio wide scanning monitors the channels in the preprogrammed radio wide scan list.
This scan list may contain up to 16 channels of any type assigned to any zone (see Section

4.13.2). Radio wide scanning is turned ON and OFF by menu selection or by the RWS

option switch (if programmed) as follows:

Note Use radio wide scanning only if two different types of channels need to be sc anned at the

same time such as conventional and SMARTNET/SmartZone. Otherwise, use the more
efficient priority scanning because there is less chance of missed calls.

• To turn radio wide scanning on, press the RWS option switch and “RW SCAN ON”
(Standard Control Head) or “RW Scan On” (Lightning Control Head) is briefly

displayed. In addition, (Standard Control Head) or (Lightning Control Head)is
displayed along with an R in the left Status position.

• To turn radio wide scanning OFF, press the RWS option switch again and “RW SCN
OFF” is briefly displayed and (Standard Control Head) or (Lightning Control
Head) with R is no longer displayed.

• If the zone or channel is changed while radio wide scanning, scanning continues
normally.

4.12.3 Scan Hold Time

When traffic is received or transmitted while scanning, there is a delay before scanning
resumes. The delay after receiving a call prevents other traffic from being received before
a response can be made. The delay after transmitting a call ensures that a response is heard
and prevents other traffic from occurring on some other channel.

Separate delay times are programmable for radio wide and priority scanning. With radio
wide scanning, delays of 2 to 7.5 seconds can be programmed. With priority scanning,
delays of 0 to 7.5 seconds can be programmed. With SMARTNET/SmartZone and P25
Trunking scanning, scan delays of 0 to 8 seconds can be programmed.

4.12.4 Transmitting in the Scan Mode

Priority Scan Mode - When the transmitter is keyed while scanning is enabled, the
transmission may occur on various channels as follows.

Conventional Operation - Transmissions can be programmed to always occur on
the priority, selected, or receive channel (if applicable). Refer to Section 5.10 for
more information.

SMARTNET/SmartZone/P25 Trunking Operation - If scanning is halted to
receive a message, programming determines if transmissions occur on the selected or
active channel. Transmissions at other times occur on the selected channel.

Radio Wide Scan Mode - The radio can be programmed to transmit on the selected or
active channel similar to SMARTNET/SmartZone and P25 trunking operation just
described.

Radio Wide Features

4.14 Over the Air Programming

OTAP is an “Over the Air” programming feature for the subscriber parameter (code plug)
files. Using the OTAP feature, parameter files can be updated and changed in the field,
eliminating the need to take the radio out of service to perform the updates. Firmware
updates cannot be made using this feature. Firmware version 8.10.x or later is required to
use conventional OTAP or P25 Trunking OTAP.

4.14.1 Radio Set Up

The current profile in the radio controls how an OTAP download is handled. How this is
programmed determines the possible actions the radio should take: “Activate
Immediately” or “Update on Reboot”.

Update on Reboot

• The Standard Control Head displays “OTAP UPDAT RECEIVED. RBOOT RDIO”
after a successful OTAP download, prompting the user to reboot the radio to apply the
update.

• The Lightning Control Head displays the message “OTAP Update Received. Reboot
radio to update.” after a successful OTAP download, prompting the user to reboot the
radio to apply the update.

4.14.2 OTAP Transfer Times

Larger files tie up the radio for a long time. Therefore, any user interface event, such as a
channel change, zone change, button press or toggle switch position change (portable
radios only) stops the OTAP procedure and returns the radio to normal operating mode.
For button presses/toggle switch position changes, the radio exits OTAP mode only if a
function is programmed for the button/toggle switch; otherwise, the bad tone sounds.

Low signal conditions may also cause the radio to exit OTAP. If the radio does not receive
a response from programming one minute after receiving its last data packet, the radio
stops the OTAP procedure and returns to normal operating mode.

4-16 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

4.15 Over the Internet Programming

Over the Internet Programming (OTIP) enables you to program Viking mobile radios
remotely using IP-based network services. It works with both wired (Ethernet) and
wireless (Wi-Fi) networks.

Note OTIP is only supported by Viking mobile radios running 8.12.x or later software with the

OTIP option enabled. Portable radios do not support OTIP.

4.15.1 Security

There are inherent security risks with exposing your radios on a LAN or WAN. Your
system administrator or IT department should be made aware that Viking mobile radios
using OTIP will periodically use Multicast DNS and DNS-Based Service Discovery to
coordinate availability. You may choose to completely disable OTIP functionality by not
ordering the OTIP option.

Radio Wide Features

Because OTIP-enabled radios are available to all computers on the network, you should
use network security policies with upload/download restrictions.

4.15.2 Voice Announcements

OTIP has no special restrictions for voice announcements. You can use the OTIP interface
to quickly transfer large codeplugs with many voice announcements.

4.15.3 Encryption

Armada supports industry-standard (SSH) encrypted transfers when using USB, Ethernet
or Wi-Fi network connections. If Wi-Fi is configured, you must use WPA2 Pre-Shared
Key (PSK).

4.15.4 Limitations

4.15.4.1 Disconnection Events

Armada may show a radio OTIP-connected when it is not. This is due to the nature of
service discovery on IP networks. Here are a few examples of scenarios in which this may
happen. There may be other such scenarios also:

Viking Mobile Radio Operating Manual 4-17

Draft 02 - Sep 1 2015

Radio Wide Features

• A Wi-Fi-connected radio goes out of range.

• An Ethernet-connected radio gets its Ethernet cable disconnected suddenly.

• Miscellaneous unexpected network events occur.

USB connections can interfere with OTIP connection and disconnection events. Do not
use OTIP with more than 2 USB-connected radios. (EFJohnson plans to address this
limitation in a future Armada release.)

4.15.4.2 Concurrent Transfers

Do not try to update a single radio from multiple instances of Armada at the same time. In
general, radio administrators are expected to coordinate with each other when managing
radios. OTIP is designed to allow a radio service center to connect to mobile radios
without running cables.

- When you disconnect a radio’s USB programming cable to replace it with a Wi-Fi
dongle—or vice versa—wait at least 3 seconds after you disconnect the first device
before you connect the second device.

4.16 Auto / Unmute

The user can mute the radio so they do not have to listen to dispatch. (An example is an
EMT who uses a radio’s call alert feature for notification of an emergency event.) When
receiving a call alert the radio will automatically unmute and notify the EMT of the event.

If the user has the radio muted, this feature automatically unmutes the radio if certain
programmable events occur. These events include the reception of a Call Alert, Unit Call,
or Emergency Call.

4.17 Location Services

Location Services provides GPS location information to the radio user and to network
administrators using a standardized IP based protocol. For example, a radio can send its
current location over the radio network and then IP to an application that is mapping user
locations. That application can also send commands to the radio telling it what data to
report and when to report it.

4-18 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

Radio Wide Features

It is supported on the Viking Mobile Radio, software version 8.10.x or later. Location
service requires an external GPS module connected though the RS232 serial port. The
Viking radio supports any receiver with RS232 serial output. The receiver must be
configured to transmit the GPGGA and GPRMC NMEA sentences. P25 Trunking and
Conventional IP data between a radio and an application with access to the fixed host is
supported. Basically, data flows between the radio and the system. Radio to radio
operation is not currently supported.

The radio processes GPS data from the receiver and sends it over the system to the
Location Services Host System (LSHS). The LSHS is an application that can request and
receive GPS data from radios (sometimes called “Location Server”). The Tier 2 Location
Services Standard defines a protocol between the LSHS and the radios. The protocol is
called the Location Request/Response Protocol (LRRP). EFJohnson radios with software
supporting Location Services, support the LRRP protocol. The system must support IP
data and can be P25 Digital Conventional and/or P25 Trunking.

The radio has two general Location Service features. The first is the ability to display GPS
data on the radio’s display. The second is the ability to receive commands from and send
data to a location server.

The “Display GPS” function does two things:

1 Button Press activates the GPS Data Display menu.
2 Button Press and Hold sends GPS data to the location server.

Refer to the software manual for function programming. The following table shows the
GPS data display that will display.

Triggers are divided into two types. One Shot triggers happen once and then are complete.
Periodic triggers happen periodically. Triggers may have start and stop times. Triggers
will only be armed within their specified start/stop times.

Triggering can be started both by commands from an LSHS and from programming.
Triggers marked with a * below are programmable.

The radio only supports a single trigger of each type. Sending a new trigger of a type that
is already in use will overwrite the existing trigger. This includes triggers set by the LSHS
and programming software.

4.18 Emergency Alarm Receive Indicator

The Emergency Alarm Rx feature allows a user to receive an Emergency Alarm display
and/or alert on their radio when another radio on the same system sends out an
Emergency. This feature is supported in both P25 and SmartNet/SmartZone systems. On
SmartNet/SmartZone systems the Emergency Alarm can only be received on a radio with
the same Talkgroup as the sending radio. On P25 systems the Emergency Alarm can be
received by any radio on the same system.

When an Emergency Alarm is received the radio will either sound an alert tone, display
the sending radio’s ID or Alias, or do both depending on the settings programmed. When
received, the display context of the radio is changed to display “EA Received” on the top
line and either the ID or the Alias of the radio who sent the Emergency Alarm. If the
received ID is in the Call List, then the Alias will be displayed. If it is not, the ID will be
displayed.

An Emergency Alarm will not be received when the radio is active on a voice channel, in
Emergency, or in Radio Wide Scan Mode. Also, if in Surveillance mode, the backlight
will not turn on when an Emergency Alarm is received.

When received, the display context of the radio is changed to display “EA Received” on
the top line and either the ID or the Alias of the radio who sent the Emergency Alarm. If
the received ID is in the Call List, then the Alias will be displayed. If it is not, the ID will
be displayed.

After an Emergency Alarm has been received, any press of a button (except for the PTT)
will exit the display and clear the ten-second timer. If no buttons are pressed, the display
will continue to show “EA Received” along with the ID or Alias for ten seconds.
However, the alert tone is only heard once upon receiving the alarm. There is also a timer
that will not allow the radio to receive another Emergency Alarm from the same ID for
twenty seconds. This timer is only cleared on a channel change, zone change, or after
twenty seconds has expired.

4-22 Viking Mobile Radio Operating Manual

Draft 02 - Sep 1 2015

If multiple Emergency Alarms from different radios are received within the ten second
period while the display is still showing, then only the most recent Emergency Alarm ID is
shown and the ten-second timer is reset.

4.19 Kiosk Mode

A computer may be set up in Kiosk Mode to simplify updating a user’s radio. Kiosk Mode
is a special view mode of Armada that simplifies radio interaction. It hides the entire
configuration from the user so anyone can connect their radio and have clear instructions
about what to do. Kiosk Mode is intended to be run on a remote/satellite machine. It is
more commonly used with the portable radio, but is also compatible with the mobile radio.

Before a radio connects, a screen is displayed, telling you to connect your radios.

Multiple radios may be connected at once. Each radio receives its own portion of the
screen. The user needs to follow the instructions as they display on the screen. (For more

detailed information, please refer to the Armada Programming Manual.)

Radio Wide Features

When no radio is connected, a message is displayed indicating a radio may be connected
to start. This, or a similar message while radios are connected, indicate that more radios
may be connected.

When updates are required, Armada displays a single progress bar for all updates. When
the progress bar gets to 100%, the user is instructed to disconnect their radio. The radio
will flash after it is programmed (the identify radio functionality) to help indicate which
radio completes if multiple radios are connected at once.

4.20 Analog Noise Reduction

If your administrator configures Analog Noise Reduction, the radio filters out background
noise on Conventional Analog channels, SmartNet channels, and SmartZone Analog
channels. To use this feature on your radio, an Analog Noise Reduction button, menu
item, or soft button must be programmed to turn on noise reduction.

Section5Conventional Mode Features

Conventional mode features are radio features unique or used only when operating in
conventional mode.

5.1 Monitoring Before Transmitting

With conventional operation, you may need to manually monitor the channel before
transmitting to make sure that it is not being used by someone else. If you were to transmit
while someone else was using the channel, you would probably disrupt their conversation.
With SMARTNET/SmartZone and P25 Trunked operation, monitoring is performed
automatically. Monitor conventional channels automatically or manually as follows:

5.1.1 Automatic Channel Monitoring

If the selected channel is programmed for Busy Channel Lockout (also called Transmit
Disable On Busy), monitoring is performed automatically. Refer to Section 5.3 for more
information on this feature.

5.1.2 Manual Channel Monitoring

The automatic monitoring just described may occasionally disable the transmitter when
the channel is not in use, such as if the repeater has extended hang time. In this case, you
may not want to use it and the channel must then be monitored manually as follows:

Viking Mobile Radio Operating Manual 5-1

Draft 02 - Sep 1 2015

Conventional Mode Features

Busy Indicator - With scanning disabled, note if the multi-function indicator on the
front panel is steady green. If it is green, a carrier is being detected, so the channel may
be busy. If it is not, the channel is not being used and a call can be transmitted.

Monitor Mode - There may be times when the busy indication is displayed even
though no one is using the channel. Monitoring should then be performed by disabling
Call Guard squelch (or group ID detect on P25 channels). This is usually done by
selecting the Monitor Mode (see following) or by the Normal/Selective option switch
(see Section 5.4.1).

5.2 Monitor Mode

The monitor mode unsquelches the receiver and monitors the channel even if a carrier is
not detected. Other features of this mode are as follows:

• Call Guard (CTCSS/DCS) squelch is disabled on analog channels and NAC and group
ID detect are disabled on P25 (conventional) channels.

• Signalling-dependent Busy Channel Lockout options for Tone/NAC and P25 status are
ovrerridden (see next section). (Noise option is not overridden: Monitor mode disables
the protocol-signalling events that the Busy Channel Lockout option Tone/NAC/Status
depend on, but not carrier events.)

• Scanning temporarily halts.

The Monitor Mode operates as follows:

1 To monitor the transmit frequency for activity before transmitting, briefly press the

Monitor option switch. The display then indicates “MON” (see Figure 2.3) for the
Standard Control Head or for the Lightning Control Head. The receiver
unsquelches and noise is heard even if carrier not present. The transmit frequency can
also be monitored by selecting TX Channel in the Monitor menu function’s sub menu.

2 To monitor the receive frequency instead, press and hold the Monitor option switch

until a tone sounds (based on radio programming). This can be used, for example, to
improve reception if intermittent squelching is making a weak message difficult to
understand.

3 To disable the monitor mode and return to normal operation, press the Monitor option

switch again (or select Off from the menu).

If off-hook detection is enabled, taking the microphone off-hook monitors the receive
frequency similar to Step 2. However, the receiver unsquelches only if a carrier is detected
(see Section 4.9). Pressing the Normal/Selective option switch disables Call Guard
squelch/P25 group ID detect but not scanning and P25 NAC detect (see Section 5.4).

5.3 Busy Channel Lockout

The Busy Channel Lockout (also called Transmit Disable on Busy) feature automatically
disables the transmitter if the channel is busy when the PTT switch is pressed. When the
transmitter is disabled by this feature, “BUSY” is displayed, a busy tone sounds, and the
transmitter is disabled.

The Busy Channel Lockout feature can be programmed to operate as follows. Each
conventional channel can be programmed differently.

“Off” - Busy channel lockout is disabled and the transmitter keys even if the channel is
busy.

“Noise” - If a carrier is detected on the channel, the transmitter is disabled when the
PTT switch is pressed.

“Tone (NAC)” - If an incorrect Call Guard (CTCSS/DCS) or P25 NAC code (see
Section 5.13.3) is detected, the transmitter is disabled when the PTT switch is pressed.
An incorrect code is any code other than the one programmed for the current channel.

Conventional Mode Features

“Status” - Transmission is disabled if the repeater inbound channel busy status symbol
is detected.

“Talkgroup” - Prevents transmission during calls with a different NAC or talkgroup.
Transmission is allowed during data or short terminators with the correct NAC.
Applicable to Conventional Digital channels.

If Busy Channel Override is permitted by programming, it is possible to transmit even
when the transmitter is disabled by this feature. Release the PTT switch and then quickly
press it again within one second.

5.4 Call Guard Squelch

Tone or digital Call Guard squelch (also called CTCSS/DCS signaling) can be
programmed on each conventional analog transmit and receive channel in any order
desired. The reverse burst and turn-off code are always transmitted and also detected on
channels programmed with Call Guard squelch.

The Call Guard squelch feature eliminates distracting messages intended for others using
the channel. This is done by using a subaudible tone or digital code to control the squelch.
This tone or code is unique to a user or a group on that channel. This tone or code is
transmitted with the voice signal but is not heard because it is in the subaudible range and
is attenuated by a filter. Call Guard squelch must be used in both the transmitting and
receiving radio to be functional.

Viking Mobile Radio Operating Manual 5-3

Draft 02 - Sep 1 2015

Conventional Mode Features

5.4.1 Call Guard Squelch Enable / Disable

The Normal/Selective option switch (if programmed) can be used to disable receive Call
Guard squelch (Normal/Selective Squelch) on analog channels or group ID code detection
on P25 channels. This option is also selectable via the menu. When selective squelch is
disabled, “SQ NORMAL” is flashed in the display. When it is enabled, “SQ SELECT” is
flashed on the Standard Control Head and “Squelch Selective” on the Lightning Control
Head.

When Normal Squelch is selected, the receiver unsquelches only if a carrier is detected.
Scanning and P25 NAC detection are not disabled with this mode selected. The selected
mode remains in effect until it is manually changed. Selecting another channel or cycling
power does not reselect a default condition. There is a programmable option to display the
monitor icon when the Normal Squelch mode is selected.

5.4.2 Tone Call Guard Squelch

Tone-type Call Guard squelch uses subaudible CTCSS tones from 67-254.1 Hz. Although
there are 42 tones assigned, those above 33 (210.7 Hz) are normally not used because of
their close proximity to the voice band which starts at 300 Hz. In addition, tones 11 (97.4
Hz), 39 (69.3 Hz), 40 (206.5 Hz), 41 229.1 Hz), and 42 (254.1 Hz) are normally not used
because they may cause interference with adjacent tones.

A reverse burst is transmitted when the push-to-talk switch is released and also detected
when calls are received. It is a 180-degree phase reversal for a period of time determined
by the tone frequency, and it eliminates the squelch tail (noise burst) in the receiving radio.
Both the transmitting and receiving radio must be equipped with this feature for it to be
used. The radio can be programmed to turn OFF the reverse burst feature so that the
squelch tail is not eliminated.

5.4.3 Digital Call Guard Squelch

Digitally Coded Squelch (DCS) uses digital data instead of subaudible tones to control the
squelch. This data consists of continuous repetitions of 23-bit words. There are 84 DCS
digital data tones to select from. No bit or word synchronization information is used.
When the push-to-talk switch is released, a turn-off code is transmitted which eliminates
the squelch tail similar to the reverse burst.

Conventional Mode Features

5.4.4 Disable Call Guard

The Disable Call Guard feature option lets the radio disregard any CTCSS/DCS or NAC/
Talkgroup information on the current channel. This programmable feature is best
described as a monitor mode with no white noise. In analog it is functionally the same as
turning the squelch mode to “normal.” In digital mode it is analogous to checking the
“digital squelch” box when programming the radio. The function can be programmed to
any button and the menu. The mode will stay active though channel changes (between
conventional channels) and during scan. While the feature is active the monitor icon will
be displayed.

5.4.5 Conventional Squelch Adjust

Squelch settings on a conventional analog channel can be changed by the user from -7 to
+7. A menu item or function button can be programmed for squelch adjust. While on a
conventional analog channel without emergency or scan active, the user can select the
programmed button or menu item for squelch adjust. The current squelch setting will
show on the display.

Using the up and down navigation buttons on the mobile radio, or turning the rotary knob
clockwise or counter-clockwise, the user can adjust the squelch setting to a desired level
from -7 to +7. Increasing the value towards +7 causes the squelch to open sooner for
weaker signals while decreasing towards -7 has the opposite effects. Pressing the select
button will store the new squelch setting and return the user to the main display.

5.4.6 Selective Squelch Code Select (CTCSS / DSC / NAC)

This feature allows the normal transmit and receive Call Guard (CTCSS/DCS/NAC)
programming to be temporarily overridden with a code selected from a preprogrammed
list. It is available if the Squelch Select List option switch and a CTCSS/NAC code list
have been programmed. It is also selectable via the menu and soft buttons (Lightning
Control Head only).

In addition, with the Digital Keypad Microphone, conventional systems can be
programmed for the Keypad CTCSS/DSC feature. Codes can then be selected directly
from the table by pressing the key for the code. For example, to select code 3 from the
table, simply press the “3” key. No other conventional mode functions can then be
assigned to these keys.

The CTCSS/DCS/NAC list is programmed with up to 255 tone (CTCSS) or digital (DCS)
Call Guard codes. Different codes can be programmed for the transmit and receive modes,
and carrier squelch (selective squelch disabled) can be programmed if desired. In addition,
each position can be programmed with an NAC code for use with P25 operation.

Viking Mobile Radio Operating Manual 5-5

Draft 02 - Sep 1 2015

Conventional Mode Features

When the Call Guard code is changed using this feature, it remains selected even if other
channels are selected. However, if radio power is cycled or a talk-around channel is
selected, the normal codes are reselected. When scanning, the selected code also applies to
all scanned channels. Each channel can also be programmed to always ignore the code
selected from this list and use the default code instead.

If both analog and digital (Project 25) channels can be selected or scanned, the CTCSS/
DCS code for the selected position is used for analog channels and the NAC code for the
selected position is used for P25 channels. If a channel is programmed for mixed mode
operation, the selective squelch type (analog or digital) programmed for the transmit mode
determines the selective squelch type used.

Note Call Guard codes may be permanently reprogrammed by keypad programming (see

Section 5.14).

Proceed as follows to select a code using the Squelch Select List option switch:

1 Press the Squelch Select List option switch and then rotate the Select switch to select

the desired position. The display indicates “SQ xx” where, “xx” is the selected code
from 1-255. The code number and actual code are alternately displayed (NACs are
displayed in hexadecimal).

2 To select the displayed code and return to the normal display, press the Squelch Select

List (Squelch Code Select) switch again.

3 To check which code is selected, press the Squelch Select List option switch once to

display the current selection and then again to return to normal operation.

4 To return to the normal selective squelch codes, select “DEFAULT” in this mode. As

previously described, the normal codes are also automatically reselected whenever
radio power is cycled or a talk-around channel is selected.

5.5 Penalty Timer

A penalty timer may be programmed on conventional systems to prevent transmissions for
the programmed time after the time-out timer disables the transmitter (see Section 4.3).
The penalty timer can be programmed for the same times as the time-out timer, and timing
starts when the PTT switch is released. If the PTT switch is pressed while the timer is
running the timer stops, and continues when the PTT switch is released. When the penalty
timer expires, a beep sounds and the transmitter can then be keyed.

Draft 02 - Sep 1 2015

5.6 Conversation Timer

A conversation timer can be programmed on conventional systems in addition to the time­out timer (see Section 4.3). This timer limits that total length of a conversation rather than
just the length of each transmission as with the time-out timer. The following is more
information on this timer.

• It can be programmed for times up to 7.5 minutes.

• It is reset when the time between transmissions exceeds the time programmed for the
penalty timer.

• A warning beep sounds five seconds before this timer disables the transmitter.

• When this timer disables the transmitter, a continuous tone sounds and the red transmit
indicator turns OFF. The PTT switch must then be released until the penalty timer
expires (indicated by a beep).

Conventional Mode Features

5.7 Repeater Talk-Around

Normally, all transmissions go through a repeater which usually increases range.
However, there may be times when a radio is out of range of the repeater and therefore
unable to talk to anyone even though the radio being called is only a short distance away.
To allow communication in this situation, repeater talk-around can be selected.
Transmissions then occur on the receive frequency which permits direct radio-to-radio
communication.

Repeater talk-around can be selected if the RTA option switch is programmed. This
feature can also be selected via the menu. When talk-around is enabled by this switch,
“RTA ON” is flashed in the display, and when it is disabled, “RTA OFF” is flashed. This
feature remains enabled during scanning, and changing channels or turning power OFF
does not change the selected condition. Talk-around is available on conventional channels
only. The Talkaround capability can be Disabled on a per-channel basis, requiring the user
to use the infrastructure if disabled. (Radio-to-Radio communication is not allowed.)

5.8 Displaying Transmit / Receive Frequency

If the Display Information option switch is programmed, it can be used to display the
channel frequency in megahertz. Pressing this switch toggles between displaying the
standard channel alias and the frequency. The receive frequency is displayed while
receiving and the transmit frequency is displayed while transmitting. This feature may
also be selected via the menu and soft buttons (Lightning Control Head only).

Draft 02 - Sep 1 2015

Conventional Mode Features

This feature is available on conventional channels only.

5.9 Emergency Alarm and Call

Emergency Alarms and Calls are separate functions that can be individually enabled or
disabled on each analog and P25 conventional system. The Emergency option switch (or
menu selection) is required for these functions. Emergency Alarms and Calls are
transmitted on the global (radio wide) emergency zone/channel if one is programmed and
a smart console with message receiving capabilities is used. If it is not programmed, the
emergency is transmitted on the selected channel. The emergency programming of the
system to which that channel is linked controls the emergency operation.

The user can set an external line by pressing the emergency button. External devices can
trigger off of the radio’s external line. If the “Ext Emergency” Option is enabled by
programming and the user presses the emergency button, the Aux B line on the accessory
connect shall be set to low (0V). It remains low until the External Emergency Time has
passed or the user exits the emergency. If the user presses emergency during the External
Emergency Time, the timer starts over. If the user exits emergency before the External
Emergency Time has passed, the output line returns to Vbatt.

5.9.1 Emergency Alarms

An emergency alarm is a special transmission that alerts a dispatcher of an emergency
situation. It is sent automatically by pressing Emergency option switch. The system to
which the emergency channel is linked must have Emergency Alarms enabled. If it does
not, Emergency Alarms are disabled. Emergency alarms and calls can be received on
smart consoles with message receiving capabilities.

In the P25 conventional mode, a special P25 emergency data transmission is sent, and in
the conventional analog mode, an DTMF emergency ID is sent. Refer to Section 5.12.5 for
information on the MDC1200 Emergency Alert.

Proceed as follows to send an emergency alarm:

1 If required, select a channel of a system on which Emergency Alarms are enabled and

then press the Emergency option switch. The radio then automatically transmits the
emergency alarm.

2 Either Normal or Silent operation can be programmed. With the Normal mode, the red

LED lights, the emergency tone sounds, and “EMERGENCY” flashes in the display.
This indication continues to flash until the alarm mode is ended (see Step 4).
