SAFETY INFORMATION The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmissions. A list of possible hazards are: 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 vehicle.
Two-way FM radio systems must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment must be thoroughly familiar with the rules that apply to the intended type of radio operation. 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.
It is a violation of FCC rules to interrupt any distress or emergency message. As the 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 in on the air - before sending messages.
