WARNING

RA PD 404264

DANGEROUS 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 who is familiar with the

operation and hazards of the equipment and who is competent in administering first aid. When the

technician is aided by operators, he 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 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.

WARNING

Do not be misled by the term “low voltage.” Potentials as low as 50 volts may cause death under adverse

conditions.

COMMON and probe ground straps are electrically connected. Herefore, an elevated reference applied to

any is present on each - as indicated by the yellow warning bands under the probe retractable hook tips.

For Artificial Respiration, refer to FM 21-11,

Power Source

This product is intended to operate in a power module connected to a power source that will not apply more

than 250 volts rms between the supply conductors or between either supply conductor and ground. A

protective ground connection by way of the grounding conductor in the power cord is essential for safe

operation.
