Safety Information
Every radio, when transmitting, radiates
energy into the atmosphere which may,
under certain conditions, cause the
generation of a spark. All users of vehicles
fitted with radios should be aware of the
following warnings (see also “Important
Electromagnetic Emission Information”
below).
• Do not operate radio near flammable liquids or in
the vicinity of explosive devices.
During normal use, the radio will subject you to radio
energy substantially below the level where any kind of
harm is reported. To ensure personal safety, please
observe the following simple rules:
• Do not transmit when the antenna is very close to,
or touching, exposed parts of the body, especially the
face and eyes.
• Do not hold the transmit (PTT) key in when not
desiring to transmit.
• Check the laws and regulations on the use of two-
way mobile radios in the areas where you drive.
Always obey them. Also, when using your phone
while driving, please:
- give full attention to driving,
- use hands-free operation, if available, and
- pull off the road and park before making or
answering a call if driving conditions so require.
Airbag Warning
An air bag inflates with great force.
Do not place objects, including
communication equipment, in the area
over the air bag or in the air bag
deployment area. If the communication
equipment is improperly installed and
the air bag inflates, this could cause
serious injury.
Installation of vehicle communication equipment
should be performed by a professional installer/
technician qualified in the requirements for such
installations.
An air bag’s size, shape and deployment area can vary by
vehicle make, model and front compartment
configuration (e.g., bench seat vs. bucket seats). Contact
the vehicle manufacturer’s corporate headquarters, if
necessary, for specific air bag information for the vehicle
make, model and front compartment configuration
involved in your communication equipment
installation.

Operational Safety Warnings
For vehicles equipped with Electronic
Ignition Systems, check the vehicle
service manual for warnings about the
use of two-way radio equipment in the
vehicle.
The radio may switch into transmit mode, immediately
upon being connected to power, if an open circuit exists
between pins 4 and 9 of the Accessory Connector. To
avoid personal injury and/or damage to the radio,
ensure that a jumper wire or an emergency switch that
has normally closed contacts is connected between pins
4 and 9 of the accessory connector before the radio is
connected to vehicle battery power or any other power
supply.
Radio Care / Handling Cautions
• Avoid physical abuse; do not pound, drop, or throw
the radio. It may damage exposed parts such as
controls and connectors.
• Do not connect accessories other than Motorola
compatible equipment, as it may damage the radio.
For a list of available compatible accessories consult
the Mobius Accessories Guide part number
68P02058U52, or the MCS 2000 Accessories Guide
part number 68P81080C47, or check with your local
Motorola representative.
• The use of a Mini UHF Adaptor can damage the RF
Antenna Connector and lead to radio failure, and is
grounds for voiding warranty.
• Operating the radio without an antenna cable
attached may lead to radio failure and is grounds for
voiding warranty.
Important Electromagnetic
Emission Information
In August, 1996, The Federal Communications
Commission (FCC) adopted an updated safety standard
for human exposure to radio frequency electromagnetic
energy emitted by FCC regulated equipment. Motorola
subscribes to this same updated safety standard for the
use of its products.
In keeping with sound installation practice and to
maximize radiation efficiency, a one-quarter (1/4) wave
length antenna should be installed at the center of the
vehicle roof. If it is necessary to mount the antenna on
the vehicle's trunk lid, an appropriate 3db gain antenna
should be used. This installation procedure will assure
that vehicle occupants will be exposed to radio
frequencyenergylevelslowerthanthelimitsspecifiedin
the standard adopted by the FCC in General Docket
79144.
To assure that radio frequency (RF) energy exposure to
bystanders external to a vehicle is lower than that
recommended by FCC adopted standard, transmit with
any mobile radio only when bystanders are at least two
(2) feet/60 cm away from a properly installed externally
mounted antenna for radios with less than 50 watts of
output power, or three (3) feet/90 cm away for radios
with 50 watts or greater power.
Control Station Operation
In the event of Control Station operation, to assure
operators and bystanders are exposed to radio frequency
(RF) energy levels lower than the limits specified in the
FCC adopted standard, the antenna should be installed
outside of any building, but in no instance shall the
antenna be within two feet/60 cm (less than 50 watts
power output) or within three feet/90 cm (50 watts or
higher power output) of station operators or bystanders.

LP Gas Warning
It is mandatory that radios installed in
vehicles fuelled by liquefied petroleum
gas conform to the National Fire
Protection Association standard NFPA 58,
which applies to vehicles with a liquid
propane(LP) gas container inthe trunk or
other sealed off space within the interior
of the vehicle. The NFPA58 requires the
following:
• Any space containing radio equipment shall be
isolated by a seal from the space in which the LP gas
container and its fittings are located.
• Removable (outside) filling connections shall be
used.
• The container space shall be vented to the outside.
Anti-Lock Braking System (ABS)
and Anti-Skid Braking System
Precautions
Disruption of the anti-skid/anti-lock
braking system by the radio transmitter
may result in unexpected vehicle motion.
Motorola recommends the following radio installation
precautions and vehicle braking system test procedures
to ensure that the radio, when transmitting, does not
interfere with operation of the vehicle braking system.
Installation Precautions
Always provide as much distance as possible between
braking modulator unit and radio, and between braking
modulator unit and radio antenna and associated
antenna transmission line. Before installing radio,
determinelocationofbrakingmodulatorunitinvehicle.
Depending on make and model of vehicle, braking
modulator unit may be located in trunk, under
dashboard, in engine compartment, or in some other
cargo area. If you cannot determine location of braking
modulator unit, refer to vehicle service manual or
contact a dealer for the particular make of vehicle.
If braking modulator unit is located on left side of the
vehicle, install radio on right side of vehicle, and
conversely.
Route all radio wiring including antenna transmission
line as far away as possible from braking modulator unit
and associated braking system wiring.
Never activate radio transmitter while vehicle is in
motion and vehicle trunk lid is open.
Braking System Tests
The following procedure checks for the most common
types of interference that may be caused to vehicle
braking system by a radio transmitter.
1. Run vehicle engine at idle speed and set vehicle
transmission selector to PARK. Release brake pedal
completely and key radio transmitter. Verify that
there are no unusual effects (visual or audible) to
vehicle lights or other electrical equipment and
accessories while microphone is NOT being
spoken into.
2. Repeat Step 1. except do so while microphone IS
being spoken into.
3. Press vehicle brake pedal slightly just enough to
light vehicle brake light(s). Then repeat Step 1.
and Step 2.
4. Press the vehicle brake pedal firmly and repeat
Step 1. and Step 2.
5. Ensure that there is a minimum of two vehicle
lengths between front of vehicle and any object in
vehicle’s forward path. Then, set vehicle
transmission selector to DRIVE. Press brake pedal
just far enough to stop vehicle motion completely.
Key radio transmitter. Verify that vehicle does not
start to move while microphone is NOT being
spoken into.
6. Repeat Step 5. except do so while microphone IS
being spoken into.
7. Release brake pedal completely and accelerate
vehicle to a speed between 15 and 25 miles/25 and
40 kilometers per hour. Ensure that a minimum of
two vehicle lengths is maintained between front of
vehicle and any object in vehicle’s forward path.
Have another person key radio transmitter and
verify that vehicle can be braked normally to a
moderate stop while microphone is NOT being
spoken into.
8. Repeat Step 7. except do so while microphone IS
being spoken into.
9. Release brake pedal completely and accelerate
vehicle to a speed of 20 miles/30 kilometers per
hour. Ensure that a minimum of two vehicle
lengths is maintained between front of vehicle and
any object in vehicle’s forward path. Have another
person key radio transmitter and verify that
vehicle can be braked properly to a sudden (panic)
stop while microphone is NOT being spoken into.
10. Repeat Step 9. except do so while microphone IS
being spoken into.
11. Repeat Step 9. and Step 10. except use a vehicle
speed of 30 miles/50 kilometers per hour.
