SAFETY TRAINING INFORMATION

SAFETY TRAINING INFORMATION

WARNING

This radio produces RF electromagnetic energy when
transmitting and is designed and classified for “Occupa­tional Use Only”. Radio equipment with this classifica­tion must be used only during the course of employment
by individuals aware of the hazards and the ways to mini­mize such hazards. This radio is NOT intended for use by
the General Population in an uncontrolled environment.

This radio has been tested and complies with FCC
RF exposure limits for “Occupational Use Only”. In
addition, it complies with the following standards and
guidelines with regard to RF energy and electromagnetic
energy levels and evaluation of such levels for exposure
to humans:

• FCC OET Bulletin 65 Edition 97-01 Supplement C,

Evaluating Complian ce with FCC Guidelines for
Human Exposure to Radi o Frequency Electromagneti c
Fields.

• American National Standards Institute (C95.1-1992),

IEEE Standard for Safety Levels with Respect to
Human Exposure to Radi o Frequency Electromagneti c
Fields, 3 kHz to 300 GHz.

• American Nati onal S tandards Instit ute (C95.3 -1992),

IEEE Recommended Practice for the Measurement of
Potentially Hazardous Electromagnetic Fields - RF
and Microwave.

CAUTION

To ensure that your exposure to RF electromagnetic
energy is within the FCC allowable limits for occupa­tional use, always adhere to the following guidelines:

• DO NOT use any accessories not specifically autho-

rized by the E.F. Johnson Company for use with this
radio such as batteries, speaker-microphones, belt
clips, and antennas. The use of unauthorized accesso­ries can cause FCC RF exposure compliance require­ments to be exceeded.

• ALW AYS keep the antenna and ra dio at l east 2 .54 cm

(1.0 inch) away from your body when transmitting to
ensure FCC RF exposure compliance requirements are
not exceeded. The best transmission quality results
when the antenna is at least 5 cm (2 inches) away from
your mouth and angled slightly to one side.

• This unit has not been tested for FCC RF exposure

compliance in applications where the unit is transmit­ting while body worn on the belt clip. This product is
not intended for use in applications where transmis­sions are required while the un it is body wo rn with the
use of the belt clip.

NOTE: The preceding information is provided to make
you aware of RF exposure and what to do to ensure that
this radio is operated within FCC RF exposure limits.

Electromagnetic Interference/Usage
Compatibility

This device complies with Part 15 of the FCC rules.
Operation is subject to the condition that this device does
not cause harmful interference. In addition, changes or
modification to this equipment not expressly approved
by the E.F. Johnson Company could void the user’s
authority to operate this equipment (FCC Rules, 47CFR
Part 15.19).

• DO NOT operat e the radio wi thout the p roper antenna

attached. This may damage the radio and cause FCC
RF exposure limits to be exceeded. The proper antenna
is the antenna supplied wi th th e r adi o by t he ma nufac­turer or an antenna specifically authorized by the
manufacturer for use with this radio.

• DO NOT transmit more than 50% of total radio use

time (50% duty cycle ). Transmitting for more than
50% of the time can cause FCC RF exposure compli­ance requirements to be exceeded. This radio is trans­mitting whenever the i ndicator on the front panel is red
continuously. Pressing the PTT switch on the side
usually causes the radio to tra nsmit.

DO NOT operate it in areas that are sensitive to RF
energy such as aircraft, hospitals, blasting sites, and fuel
storage sites. Areas with potentially flammable atmo­spheres are usually, but not always, clearly posted. These
may include gas stations, fuel and chemical storage and
transfer stations, below deck on boats, and areas where
the air contains flammable chemicals or particles such as
grain dust or metal powders.

Dispose of the nickel metal-hydride (NiMH) or
nickel-cadmium (NiCd) battery used by this radio in
accordance with local regulatio ns. DO NOT dispose of i t
in fire because it can explode. Also, do not short the
terminals because it may become very hot.

GENERAL OPERATION

Turning Power On

Power is turned on and off by the top panel On­Off/Volume switch. When power is initia ll y tur ned on,
the transceiver goes through a self test routine in
which the following information is displayed:

• Currently selected zone

• Individual ID of the radio if a conventional P25

channel is selected

• Unit ID of the radio if a SMARTNET/SmartZone

channel is selected

• Selected channel alias (last)

Programming determines if the transc eiver
powers up on the last selected zone or the pre­programmed home zone. The last selected channel of
the displayed zone is always selected on power up.

Setting Volume

The relative volume level can be determined by
the position of the index on the volume knob or a
reference tone as follows. The minimum volume level
may be set by programming. This can prevent missed
messages resulting fro m inadvertently turning the
volume to an inaudible level.

• If a key press tone is enabled, a short tone sounds

when a key is pressed.

• If a conventional channel is selected and the

Monitor option key or menu parameter is
programmed, pressing that key unsquelches the
receiver and either voice or background noise is
heard (see page 16). If a SMARTNET/SmartZone
channel is sele cted, the r eceiver ca nnot be manually
unsquelched.

GENERAL OPERATION

Power-Up Password

The power-up password feature prevents unau­thorized use of the transceiver by locking the keypad
on power up until t he pr oper pa ssword is entered. This
feature is enabled or disabled by programming.

When it is enabled, “ENTER PSWD” is briefly
displayed when power is turned on. The eight-digit
numeric password must be then be entered as follows.
If an incorrect password is entered, “INCORRECT” is
displayed and it must be re-entered.

DTMF Keypad Models - Enter the password using
the 0-9 keys and then press the Enter (F2) key when
finished. If a mistake is made, the last digit can be
erased by pressing the F1 (Clear) key.

Limited Keypad Models - Select the proper number
for each position by pressing the Up/Down switch.
When the proper number for a position is displayed,
select it and move on to the next position by pressing
the F2 (Enter) key.

Zone And Channel Select

Zone Select

The front panel Up/Down switch changes and
displays the current zone. When not in special modes
such as the menu mode, pressing either the top or
bottom part of this switch once displays the current
zone number as “Zone x”. Then quickly pressing it
again changes the selected zone up or down.

After the highest programmed zone is displayed,
wrap-around to the lowest programmed zone occurs
and vice versa. The selected zone is also displayed
briefly on power up.

Channel Select

Channels are selected by the rotary 16-position
switch on the top panel. The alias (identification) for
the selected channel/group is displayed continuously
during normal operation.

When an unprogrammed channel is selected,
“UNPROGRAMD” is displayed and a tone sounds (if
tones are enabled). When conventional channels are

selected and the Display Information option key or
menu parameter is programmed, either the channel
frequency or alias can be displayed (see page 18).

Low Battery Indication

NOTE: If the transceiver contains hardware (encryp­tion) keys, be sure to reattach a battery wit h i n app roxi­mately one minute to prevent the loss of these keys.

A low-battery condition is indicated by the
icon in the display. The battery should be recharged or
replaced as soon as practical after this indication
appears. Once this indication appears, it stays on until
power is cycled.

The following additional
and conditions may be enabled by programming:

low battery indications

• A chirp sounds once a minute in the standby and

transmit modes.

• A chirp sounds each time the PTT switch is pressed.

• Top panel LED indicator flashes red every 30

seconds in the receive mode.

• Low power is selected when transmitting.

As indicated in the preceding “Note”, the trans­ceiver must be connected to a constant power sourc e
to preserve the hardware ( encrypti on) keys in memory.
Since thes e keys are ma intained in m emory for only
about 1 minute without a battery attached, be sure to
reattach a battery within that time if th ese keys are
used. Refer to see page 10 for more information on
encryption keys.

Backlight

The backlight for the disp la y and opt ion keys can
be programmed to au tomati call y tur n on whe n any key
is pressed. It then automatically turns off after a
programmed delay of 0-7.5 seconds so that battery
drain is minimized. If the Backlight option key or
menu parameter is programmed, it can be used to
manually turn the backlight on and off.

Keypad Lock

The Keypad Lock feature is used to temporarily
disable the front panel keys to prevent accidental key
presses. This feature is available if the Keypad Lock
option key is programmed.

Part No. 002-5100-100

GENERAL OPERATION

To lock the keypad, simply press the Keypad
Lock option key. Then to unlock the keypad again,
press and hold this key until a tone sounds (approxi­mately 1 second).

With DTMF keypad models, the DTMF keys can
also be totally disabled by programming on some or
all channels. The Keypad Lock feature then has no
affect on those keys.

Setting Squelch

This transceiver does not have a squelch control.
The squelch level is fixed and normally does not
require readjustment.

Transceiver Operating Modes

Introduction

Each selectable channel can be programmed for
either conventional or SMARTNET/SmartZone opera­tion. For example, Zone 1/Channel 1 could be a
conventional channel, Zone 1/Channel 2 a
SMARTNET channel, and so on. Your system oper­ator can tell you what type or types of operation are
programmed. Mode information on these modes
follows.

Conventi onal Operating Mode

This is a non-trunked operating protocol which
accesses independent radio channels. There is no auto­matic access to several c hannels. Monitoring of the
channel before transmitting may not be automatic in
this mode, so you may have to do it manually to make
sure that it is not in use. Either analog or digital
(Project 25) s ig nal ing may be used. Operatin g f ea tur es
unique to this mode are described starting on page 16.

SMARTNET/SmartZone Operating Mode

This is a trunked operating protocol that provides
automatic access to several channels. A “channel”
actually selects a talk group which is programmed
with one or more ID codes that determine what
mobiles are being called and what calls are received.
Monitoring is performed automatically, and special
tones and messages indicate busy and out-of-range

conditions. Enhanced features include roaming
(SmartZone only), telephone, private, and emergency
calls, Call Alert™, and messagi ng. Either analog or
digital signaling may be used. Operating features
unique to SMARTNET/SmartZone operation are
described starting on page 23.

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. Once a
control channel is found, it attempts to register on the
radio system and the alias (name) of the selected
channel is displayed. 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” or a
similar message is di splayed an d the radi o continue s to
search for a control channel.

The control channel transmits and receives
system information to and from all radios register ed on
the system. Therefore, once a contro l channel i s found,
it is contin uously monitored for inco ming call in for­mation and is used to make call requests. The radio
automatically chang es t o a tra ffic channel to plac e and
receive cal l s and then re turns to the co ntrol channel
when the call is complete.

Secure Communication

General

This transceiver may be optionally e quipped to
provide secure communication on some or all chan­nels. This feature encrypts your voice so that it can be
understood only by someone using a transceiver
equipped with a similar encryption device and encryp­tion codes .

When a secure call is recei ved or transmitted,

is indicated in the di spl ay. Secure communication
can be programmed on a per channel basis to operate
in various ways. If the current channel is programmed
to allow it to be selected, secure communication can
be manually enabled and disabled by the Clear/Secure
option key or menu parameter. In the receive mode,
secure calls may be auto detected or only calls coded
like the transmit signal may be received.

If the “Clear” mode is selected by Clear/Secure

key or menu parameter and an attempt is made to

transmit on a channel fixed in the “Secure” mode by
programming, “SEC ONLY” is displayed and trans­mitting is not permitted. Conversely, if the “Secure”
mode is selected and the channel is fixed in the
“Clear” mode, “CLEAR ONLY” is displayed and
transmitting is not permitted.

If your transceiver has encryption, consult your
system oper ator for more information o n how it func­tions in your application.

Encryption (Hardware) Keys

NOTE: A nearly constant power source must be
applied to the radio to main tain the encryp tion keys in
memory . Ther efor e, when changing the battery , be su re
to reattach another battery within one minute. If it is
not, these keys may be lost and will need to be
reloaded again.

RADIO-WIDE FEATURES

Option Keys

Each channel programmed for encryption has an
encryption key associated with it. Up to 16 keys can
be loaded into the radio, and the location from 0-15
refers to the “Hardware” location of the key. If more
than one key is loaded, the Hardware Key Select
option key may be programmed to select another key
for a channel. A new key selection remains in affect
until it is manually changed again. Select a hardware
key as follows:

1. Press the Hardware Key Select key o r select that

menu parameter and HWKEY x is displ ayed (“x” is
the current key selection from 0-15).

2. Press the Up/Do wn switch to display t he desired key

and then press t he Hardware Key Select key again or
F2 key to select it and return to normal operation.

Almost all the transceiver keys are programmable
unless they are dedicated to a specific function. These
keys can be programmed by your system operator for
one set of functions in the Conventional mode and
another in the SMARTNET/SmartZone mode as
described on page 10. Table 5 on page 12 lists the
programmable keys, the functions that can be
programmed in each mode, and the page of this
manual on which the function is described.

Menu Mode

Most functions that can be controlled by an
option key can also be controlled by the menu mode.
An exception is Keypad Lock which can be cont ro lled
by an option key only. The functions that can be
controlled by the menu mode are also shown in Table
5 on page 12. Only parameters that apply to the
selected channel type (Conventional/SMARTNET/
SmartZone) are displayed.

When the menu mode is used, the F1 and F2 k eys
become dedicated menu mode control keys: F1 is
Back/Clear, and F2 is Menu Select/Enter. If the menu
mode is disabled, these keys can be programmed for
other functions. The menu mode operates as follows:

Menu

1. To select the menu mode, press the F2 key. Up to
three menu para meters are t hen displ ayed as sho wn
in the preceding illustration.

2. To scroll up or down through the menu parameter
list, press the Up/Down switch. The selected
parameter is indicated by a dark bar.

3. To display the available modes for a highlighted
parameter, press the F2 key. The currently selected
mode is indicated by an asterisk.

NOTE: Some parameters cannot be selected with
scanning enabled.
