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. ExplosiveAtmospheres

Just as it is dangerous to fuel a vehicle with the motor running, be sure to

turnthe radio offwhilefuelingthevehicles. Do notcarry containersof 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 thetypeof 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 500feetoftheblastingcaps. Alwaysobeythe"TurnOffTwoWay

Radios" signs posted where dynamite is being used. When transporting

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 burnsor related physical injury from radio frequency energy,do

notoperatethetransmitterwhenanyoneoutsideofthevehicleiswithintwo

feet of the antenna.

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

Association standard (NFPA) 58 which requires that:

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

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.

•Keepbothhandsonthesteeringwheelandthehandsetinitscradlewhenever

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.

•Whentalkingfromamovingvehicleisunavoidable,driveintheslowerlane.

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, youmust be thoroughlyfamiliar with the rules that apply

toyourparticulartypeofradiooperation. Followingtheseruleswillhelptoeliminate

confusion, assure the most efficient use of existing radio channels, and result in a

smoothly functioning radio network.

When using your two-way radio remember these rules:

1. ItisaviolationofFCCrulestointerruptanydistressoremergencymessage.

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 reportinga fire,or askingfor help in an accident -KEEP

OFFTHE AIR! Emergency calls have priority over all other messages.

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

3. Itisagainstthelawto sendfalse callletters,orafalsedistressoremergency

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.

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

authorized or certified electronic technician.

TheGE-MARCsystemisalreadyautomaticallyidentifiedand doesnot

require identifying yourself.
