WARNING
DANGEROUS VOLTAGE
is used to operate this equipment
DEATH ON CONTACT
may result if safety precautions are not observed.
Never work on electronic equipment unless there is someone nearby who is familiar with the operation and hazards of
the equipment and is able to give first aid. When the technician is aided by operators, he must warn them about
dangerous areas.
When possible, shut off power to equipment before beginning work on equipment. Ground every capacitor likely to hold
a dangerous potential. When working inside equipment, after the power has been turned off, always ground every part
before touching it.
Be careful not to contact high-voltage connections when installing or operating this equipment.
When possible, keep one hand away from equipment to reduce the hazard of current flowing through the vital organs of
the body.
Read FM 21-11, First Aid for Soldiers, and learn how to administer artificial respiration.
WARNING
Do not be misled by the term "low voltage." Under adverse conditions, potentials as low as 50
volts may cause death.
