Radio Care

CAUTION:

• Your radio casting has a vent port that allows for
pressure equalization in the radio. Never poke
this vent with any objects, such as needles,
tweezers, or screwdrivers.This could create leak
paths into the radio and the radio’s submergibility
will be lost.

• Your radio is designed to be submerged to a
maximum depth of 6 feet, with a maximum
submersion time of 2 hours. Exceeding either
maximum limit may result in damage to the
radio.

• Elastomer technology materials used for seals in
rugged portable radios can age with time and
environmental exposure. Therefore, Motorola
Solutions recommends that rugged radios be
checked annually as a preventive measure in
order to assure the watertight integrity of the
radio. Motorola Solutions details the
disassembly, test, and reassembly procedures
along with necessary test equipment needed to
inspect, maintain and troubleshoot radio seals in
the radio’s service manual.

• If the radio battery contact area has been
submerged in water, dry and clean the radio
battery contacts before attaching a battery to the
radio. Otherwise, the water could short-circuit the
radio.

• If the radio has been submerged in water, shake
the radio well so that any water that may be
trapped inside the speaker grille and microphone
port can be removed. Otherwise, the water will
decrease the audio quality of the radio.

• Do not disassemble the radio. This could
damage radio seals and result in leak paths into
the radio. Any radio maintenance should be
performed only by a qualified radio technician.

17

English

Cleaning Your Radio

CAUTION:

Do not use solvents to clean your radio as most
chemicals may permanently damage the radio
housing and textures.
Do not submerge the radio in the detergent
solution.

To clean the external surfaces of your radio, follow the
procedure described next.

1 Combine one teaspoon of mild dishwashing

detergent to one gallon of water (0.5% solution).

2 Apply the solution sparingly with a stiff, non-metallic,

shortbristled brush, making sure that excess
detergent does not get entrapped near the
connectors, controls, or crevices. Rinse and then dry
the radio thoroughly with a soft, lint-free cloth.

3 Clean battery contacts with a lint-free cloth to

remove dirt or grease.

Proper Ways to Handle the Radio

• Do not pound, drop, or throw the radio unnecessarily.
Never carry the radio by the antenna.

• Avoid subjecting the radio to an excess of liquids.

• Avoid subjecting the radio to corrosives, solvents or
chemicals.

• Do not disassemble the radio.

• CAUTION:

Do not use the radio without an accessory
connector or a dust cover in place as
contamination can build up on the contacts.

• When charging the radio using a wall mounted charger,
the radio must be turned off. Otherwise, the Man Down
Alert and Emergency may be accidentally triggered.

Additional Performance Enhancement

The following performance enhancements are some of the
latest creations designed to enhance the security, quality,
and efficiency of the radios.

ASTRO 25 Enhanced Data

ASTRO 25 Enhanced Data is optimized to handle different
message sizes and variable update rates from different
applications of the radio. Add Enhanced Data to the
Integrated Data system with a software installation to
improve data channel efficiency and enable denser network
traffic.

Dynamic System Resilience (DSR)

DSR ensures the radio system is seamlessly switched to a
backup master site dynamically in case of system failure.
DSR also provides additional indication such as failure
detection, fault recovery, and redundancy within the system
to address to the user in need. Mechanisms related to the
Integrated Voice and Data (IV&D) or data centric are all
supported by DSR.

CrossTalk Prevention

This feature prevents crosstalk scenarios from happening,
especially when a wideband antenna is used. This feature
allows the adjustment of the internal SSI clock rate of the
radio. This subsequently reduces the possibility of radio
frequency interfering spurs and prevents the issues of
crosstalk.

Encrypted Integrated Data (EID)

EID provides security encryption and authentication of
IV&D data bearer service communication between the
radio and the Customer Enterprise Network.

19

English

SecureNet

SecureNet allows user to perform secured communications
on an Analog or Motorola Data Communication (MDC)
channel. The MDC Over-the-Air Rekeying (OTAR) feature
will allow users to perform OTAR activities on an MDC
channel.

P25 Digital Vehicular Repeater System (DVRS)

Motorola Solutions offers an MSI Certified APX compatible,
3rd Party, P25 Digital Vehicular Repeater System (DVRS)
that provides low cost portable radio coverage in areas
where only mobile radio coverage is available and portable
radio coverage is either intermittent or non-existent.

Conventional Talkgroup and Radio Scan Enhancements

A few enhancements have been made to the Conventional
Talkgroup at the system. These enhancements improve the
Scan feature operation significantly when multiple agencies
are using a single conventional radio frequency channel.
These enhancements allow users to use Selective Squelch
to operate on only the subset of talkgroups that are

relevant to the users rather than all talkgroups on the
channel. These Scan improvements have been made to
eliminate the audio holes that were present and to turn on
the busy LED when activity is present on the channel.
Mixed Vote Scan and Standard Conventional Scan
configurations are supported. Priority Operation is also
supported.

Up to 30 different talkgroups can be supported using
conventional channels. A maximum of four talkgroups can
be supported when Vote Scan channels are being used.

Smart PTT is supported with this enhancement as Smart
PTT prevents users from transmitting while other users are
on the channel.

NOTICE:

User Selectable Talkgroups are not compatible with
this Conventional Talkgroup Enhancement.

What Your Dealer/System Administrator Can Tell You

Check with your dealer or system administrator for the
correct radio settings, if the radio is to be operated in
extreme temperatures (less than -30 °C or more than +60
°C).

20

You can consult your dealer or system administrator about
the following:

• Is your radio programmed with any preset conventional
channels?

• Which buttons have been programmed to access other
features?

• What optional accessories may suit your needs?

When the radio is programmed with Man Down
feature, special care is required when charging the
radio with a wall mounted charger. See Proper

Ways to Handle the Radio on page 18 for details.

Pre-Alert Timer

This timer sets the amount of time that a Man Down
condition must be present before the radio-user is warned
of the Man Down condition.

When the radio detects that it has returned to the vertical
position or when the radio detects motion, the Pre-Alert
timer stops and is reset.

The Pre-Alert timer reinitiates when the radio detects it is in
the horizontal position or motionless again.

71

English

Post-Alert Timer

This timer sets the amount of time the radio needs to
remain in the Man Down condition before the Emergency
alarm is transmitted. When the Post-Alert Timer is initiated,
the radio alerts the user with an audible tone and displays
the “MAN-DOWN” text.

See Exiting Man Down Feature on page 73 to exit Man
Down feature.

Radio Alerts When Man Down Feature is Triggered

The Man Down alert tone volume is directly related to the
radio speaker volume. Ensure that the radio speaker
volume is loud enough so that the user does not miss the
Post-Alert tone.

NOTICE:

If the radio is programmed with Silent Emergency,
the radio inhibits the alert tone and visual alert
associated with the emergency feature.
If the radio is programmed in Surveillance Mode, the
radio inhibits all tones and lights on the radio
including the Man Down tones.

Triggering Emergency

When the user does not clear the Man Down condition and
the Post-Alert Timer comes to an end, Emergency Alarm or
call is triggered. The radio sends emergency message to
units within the same Talkgroup. The radio also sends ID
number and GPS coordinates to dispatcher if these
features are enabled. User can exit Emergency following
the Emergency procedure. See Emergency Operation on

page 60 for details.

Global Positioning System/Global Navigation Satellite System

The Global Navigation Satellite System (GNSS) in the radio
uses information from the Global Positioning System (GPS)
to determine the approximate geographical location of your
radio. The geographical location is expressed as latitude
and longitude or Military Grid Reference System (MGRS)
format per request from customers.

NOTICE:

This feature is addressed as GPS across the
manual as the naming convention of the buttons
and strings remain the same as the legacy feature
of GPS.

The availability and accuracy of this location information
(and the amount of time that it takes to calculate it) varies
depending on the environment in which you are using the
GPS feature.

For example, GPS location fixes are difficult to obtain
indoors, in covered locations, between high buildings, or in
situations where you have not established a clear broad
view of the sky.

79

English

Once GPS is enabled, the radio displays the GPS icon on
the screen. The dispatcher can always request the system
to determine the real-time location coordinates of the radio.

GPS Operation

The GPS technology uses radio signals from earth orbiting
satellites to establish location coordinates. Therefore,
maximizing your view of unobstructed sky is essential for
optimum performance.

Where adequate signals from multiple satellites are not
available (usually because you cannot establish a view of a
wide area of the sky), the GPS feature of your radio will not
work. Such situations include but are not limited to:

• Underground locations

• Inside buildings, trains, or covered vehicles

• Under any metal, or concrete roof, or structure

• Between tall buildings or under dense tree-cover

• In temperature extremes outside the operating limits of
your radio

Even where location information can be calculated in such
situations, it may take longer to do so, and your location
estimate may not be as accurate. Therefore, in any

emergency situation, always report your location to your
dispatcher.

Keep in mind that the accuracy of the location information
and the time it takes to obtain it varies depending upon
circumstances, particularly the ability to receive signals
from an adequate number of satellites.

NOTICE:

Even where adequate signals from multiple
satellites are available, your GPS feature only
provides an approximate location, usually within 10
meters from your actual location, but sometimes
farther away.

The satellites used by the GPS feature are controlled by
the U.S. government and are subject to changes
implemented in accordance with the Department of
Defense GPS user policy and the Federal Radio Navigation
Plan. These changes may affect the performance of the
GPS feature on your radio.

GPS Performance Enhancement

Sometimes, the GPS feature may be unable to complete a
location calculation successfully. You then see a message
indicating that your radio cannot connect to enough visible
satellites.

80

English

To maximize the ability of your radio to determine a fix,
take note of the following guidelines:

• For your initial fix, hold the radio in the face position.

• Stay in the open. The GPS feature works best where
there is nothing between your radio and the open sky.

Peer-Location on the Display (ASTRO Conventional only)

This feature is only available for radio-to-radio voice
transmissions, dispatch call and selective call in
conventional ASTRO system. For radio-to-radio
transmission, in order to allow the radio to show peer­location, the voice should be directly sent from one radio to
another radio without passing through any infrastructure
facility such as repeaters, phone, or DVRS system. Both
the transmitting radio and receiving radio must be
configured to enable them to send and/or receive the GPS
coordinates. You can check with your nearest qualified
technician for more details.

NOTICE:

If the receiving radio is operating in a Mixed Mode
channel, and the voice transmission is through the
conventional ASTRO system then the radio can
receive the location coordinates of its peers.

This feature is also operable in a Scan Active channel or
Scan Talkback channel.

Upon receiving a voice transmission with GPS coordinates
enabled on the receiving radio, the display shows the
coordinates available in full or in short coordinates. There
are two different formats available. Refer to the following
list for the details shown in the Peer-Location quick text.
Consult your agent to pick the best format to configure to
your radio.

Full location coordinates

• PTT ID (This is optional.)

• Longitude and latitude

• Relative distance or direction

Short location coordinates

• PTT ID (This is optional.)

• Longitude and latitude

81

English

NOTICE:

If the transmitting radio is stale at its location after a
period of time, the receiving radio display shows
ID:<PTT ID> LKL: <Coordinates> <distance>.
If the radio is not configured to show PTT ID, you
see LAST KNWN LOC: <Coordinates>

<distance>.

If the transmitting radio does not have GPS or the
receiving radio could not decode the GPS signal of
the received signal, the receiving radio display
shows ID:<PTT ID> UNK LOC. The PTT ID seen
here is optional to be shown on the display per
requirement of usage.

Trunking System Controls

This chapters explains the trunking system control features
in your radio.

Operating in Failsoft System

The failsoft system ensures continuous radio
communication during a trunked system failure. If a
trunking system fails completely, the radio goes into failsoft
operation and automatically switches to its failsoft channel.

During failsoft operation, your radio transmits and receives
in conventional operation on a predetermined frequency.
You hear a medium-pitched tone and the display shows
FAILSOFT.

When the trunking system returns to normal operation, your
radio automatically leaves failsoft operation and returns to
trunked operation.

To continue in Failsoft and to communicate with other
talkgroups, refer to the following procedure.

1 Rotate the Mode Knob to change to a different

repeater frequency.

2 Press the PTT button to talk, and release the button

to listen.

Out-of-Range Radio

When your radio goes out of the range of the system, it can
no longer lock onto a control channel.

currently selected zone/channel combination and OUT RNG.
Your radio remains in this out-of-range condition until it
locks onto a control channel, it locks onto a failsoft channel,
or it is turned off.

82

English

Site Trunking Feature

If the zone controller loses communication with any site,
that site reverts to site trunking.

The display shows the currently selected zone/channel
combination and STE TRNK.

NOTICE:

When this occurs, you can communicate only with
other radios within your trunking site.

Locking and Unlocking a Site

This feature allows your radio to lock onto a specific site
and not roam among wide-area talkgroup sites. This
feature should be used with caution, since it inhibits

Pairing with Low Frequency-Motorola Proximity Pairing (LF-MPP) Feature

Ensure that Bluetooth feature of your radio is on and the
Bluetooth tones are enabled.

Bluetooth tones, Bluetooth menu and preprogrammed
buttons must be preprogrammed by a qualified radio
technician. Check with your dealer or system administrator
for more information.

The range of Bluetooth operation when using a MCW
accessory is 10 meters line-of-sight communication. This is
an unobstructed path between the location of the signal
transmitter (your radio) and the location of the receiver
(your device or accessory).
Obstacles that can cause an obstruction in the line-of-sight
include trees, buildings, mountains, cars, and others.

For high degree of reliability, Motorola Solutions
recommends to NOT separate the radio and the accessory.

At the fringe areas of reception, both voice and tone quality
will start to sound "garbled" or "broken". To correct this
problem, simply position the accessory and radio closer to
each other (within the 10 meter defined range) to re­establish clear audio reception.

NOTICE:

Once a COTS headset is paired to your radio, it is
always connected. Therefore the battery life of the
accessory is aligned with the Talk Time power
consumption, not the Standby Time consumption.

Turn on the accessory. Then, place it close to the
radio aligning the Bluetooth Pairing Location (a blue
dot) on the radio to the Bluetooth Pairing Location (a
blue dot) on the accessory.

If the pairing process is successful, you hear an
incremental-pitched tone. The radio begins to

Using the PL Defeat Feature

This feature allows you to override any coded squelch
(DPL or PL) that might be preprogrammed to a channel.

The radio also unmutes to any digital activity on a digital
channel.

Place the preprogrammed PL Defeat switch in the
PL Defeat position.

One of the following scenarios occurs:

• You hear any activity on the channel.

• The radio is muted if no activity is present.

NOTICE:

When this feature is active, the Carrier
Squelch status indicator is displayed.

Digital PTT ID Support

This feature allows you to see the radio ID (number) of the
radio from whom you are currently receiving a
transmission. This ID, consisting up to a maximum of eight
characters, can be viewed by both the receiving radio and
the dispatcher.

The ID number of your radio is also automatically sent
every time the PTT button is pressed. This is a per-channel
feature. For digital voice transmissions, the ID of your radio
is sent continuously during the voice message.
