TM 11-5820-670-30
HIGH VOLTAGE
is used in the operation of this equipment.
DEATH ON CONTACT
may result if personnel fail to observe safety precautions.
Never work on electronic equipment unless there is another person nearby competent in
administering first aid. When aided by operators, the technician must warn them about
dangerous areas.
Whenever possible, the power supply to the equipment must be shut off before beginning
work on the equipment. Take particular care to ground every capacitor likely to hold a
dangerous potential. When working inside the equipment, after the power has been
turned off, always ground every part before touching it.
Be careful not to contact high-voltage connections or 115 vac input connections when
installing or operating this equipment.
Whenever the nature of the operation permits, keep one hand away from the equipment
to reduce the hazard of current flowing through vital organs of the body.
Do not be misled by the term “low voltage”. Potentials as low as 50 volts may cause death
under adverse conditions.
Dangerous potentials, which could cause severe electrical shock, exist at several points
throughout this equipment. When equipment is operated with the covers removed, do
not touch exposed connections, components, or dc input connections. Some
transistors have voltages present on their cases.
Do not operate radio set if any cables are frayed or other physical damage is evident.
Electrical shock to personnel could result.
Exercise care when lifting the radio set to avoid personal injury. The receiver-
transmitter weighs 25 pounds.
