3 OPERATION SAFETY RECOMMENDATIONS

3.1 TRANSMITTER HAZARDS

The operator of an
y
mobile radio should be aware of certain hazards common to the
operation of vehicular radio transmitters. A list of several possible hazards is given:
• Heat Dissipation – When the M7100 mobile is used for an extended period time in transmit mode, the
heat sink fins on top of the mobile chassis may be uncomfortable to the touch. Please exercise caution
when handling or working near the mobile when it is in use.
• Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor running, similar
hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do
not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn OFF your
radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the
radio or its accessories could generate sparks.
• Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic anti-
skid braking systems, electronic cruise control systems, etc., are typical electronic systems that can
malfunction due to the lack of protection from radio frequency energy present when transmitting. If
the vehicle contains such equipment, consult the dealer and enlist their aid in determining the expected
performance of electronic circuits when the radio is transmitting.
• Electric Blasting Caps – To prevent accidental detonation of electric blasting caps, DO NOT use
two-way radios within 1000 feet of blasting operations. Always obey the “Turn Off Two-Way
Radios” signs posted where electric blasting caps are being used. (OSHA Standard: 1926-900)
• Liquefied Petroleum (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
requiring:
o The LP gas container and its fittings.
o Outside filling connections shall be used for the LP gas container.
o The LP gas container shall be vented to the outside of the vehicle.

3.2 SAFE DRIVING RECOMMENDATIONS

(Recommended by AAA)
• Read the literature on the safe operation of the radio.
• Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in
motion.
• Place calls only when the vehicle is stopped.
• When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations
brief.
• If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and
continue the call.
• Whenever using a mobile radio, exercise caution.
