SAFETY INFORMATION

The operator of any mobile should be aware of certain hazards common to the

operation of vehicular radio transmission.

A list of possible hazards are:

1. Explosive Atmospheres

Just as it is dangerous to fuel a vehicle with the motor running, be sure to
turn the radio off while fueling the vehicles. Do not carry containers of fuel
in the trunk of the vehicle when the radio is mounted in the trunk.

2. Interference to Vehicular Electronics Systems

Electronic fuel injection systems, electronic antiskid braking systems, etc.,
are typical of the type of electronic devices that may malfunction due to the
lack of protection from radio frequency energy present when transmitting.
If the vehicle contains such equipment, consult the dealer for the make of
the vehicle and enlist his aid in determining if such electronics circuits
perform normally when the radio is transmitting.

3. Dynamite Blasting Caps

Dynamite blasting caps may be caused to explode by operating a radio
within 500 feet of the blasting caps. Always obey the

Radios"

signs posted where dynamite is being used. When transporting

" Turn Off Two Way

blasting caps in your vehicle:

a

. Carry the blasting caps in a closed metal box with a soft lining.

b

. Leave the radio

OFF

whenever the blasting caps are being put into or

removed from the vehicle.

4. Radio Frequency Energy

To prevent burns or related phy sical injury from radio frequency energy, do
not operate the transmitter when anyone outside of the vehicle is within two
feet of the antenna.

3

5. Liquefied (LP) Gas Powered Vehicles

Mobile radio installations in vehicles powered by liquefied petroleum gas
with the LP gas container in the trunk or other sealed-off space within the
interior of the vehicle must conform to the National Fire Protection

A

ssociation standard

a.

Space containing the radio equipment shall be isolated by a seal from

(NFPA) 58

which requires that:

the space containing the LP gas container and its fittings.

b.

Outside filling connections shall be used for the LP gas container.

c.

The LP gas container shall be vented to the outside of the vehicle.

SAFE DRIVING RECOMMENDATIONS FOR USERS OF MOBILE
RADIOS*

Read the literature on the safe operation of your unit.

•

Keep bo th hands on the steering wheel and the handset in its cradle whenever
the vehicle is in motion.

•

Place calls only when vehicle is stopped. Use on-hook dialing and recall
dialing to speed the time it takes to call.

•

When talking from a moving vehicle is unavoidable, drive in the slower lane.
Keep conversation brief.

•

If conversation requires taking notes or complex thought, stop the vehicle
in a safe place and continue your call.

•

Whenever you use a mobile radio you should exercise caution.

*As recommended by the AAA

OPERATING PROCEDURES

Two-way FM radio systems must be operated in accordance with the rules and

regulations of the Federal Communications Commission (FCC). As an operator of
two-way radio equipment, you must be thoroughly familiar with the rules that apply
to your particular type of radio op eration. Following these rules will help to eliminate
confusion, assure the most efficient use of existing radio channels, and result in a
smoothly functioning radio network.

4

When using your two-way radio remember these rules:

1. It is a violation of FCC rules to interrupt any distress or emergency message.

And, as your radio operates in much the same way as a telephone "party
line", always listen to make sure that the line is clear - that no one else is
on the air - before sending messages. If someone is sending an emergency
message - such as reporting a fire, or asking for help in an accident -

OFF THE AIR

! Emergency calls have priority over all other messages.

KEEP

2. Use of profane or obscene language is prohibited by Federal law.

3. It is against the law to send false ca ll letters, or a false distress or emergency

message.

4. The FCC requires that you keep conversations brief and confine them to

business. To save time, use coded messages whenever possible.

5. Using your radio to send personal messages (except in an emergency) is a

violation of the FCC rules. You may send only those messages that are
essential for the operation of your business.

6. It is against the Federal law to repeat or otherwise make known anything

you overhear on your radio. Conversations between others sharing your
channel must be regarded as confidential.

7. The FCC also requires that you identify yourself at certain times by means

of your call letters. Refer to the rules that apply to your particular type of
operation for the proper procedure.

NOTE

The GE-MARC system is already automatically identified and does not
require identifying yourself.

8. No changes or adjustments shall be made to the equipment except by an

authorized or certified electronic technician.
