SAFETY PRECAUTIONS
The following are general safety precautions that are not necessarily related
to any specific part or procedure and do not necessarily appear elsewhere in
this publication. These precautions must be throughly understood and apply
to all phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must at all times observe normal safety regulations. Do
replace components or make adjustments to the inside of the test equipment
with a high voltage supply turned on. To avoid casualties, always disconnect
power.
DO NOT SERVICE OR ADJUST ALONE
Operating personnel must at all times observe normal safety regulations. Do
not attempt to replace parts or disconnect an RF transmission or any other
high voltage line while power is applied. When working with high voltage always have someone present who is capable of rendering aid if necessary. Personnel working with or near high voltage should be familiar with modern
medthods of resuscitation.
SAFETY EARTH GROUND
An uninterruptible earth safety ground must be supplied from the main
power source to test instruments. Grounding one conductor of a two conduc
tor power cable is not sufficient protection. Serious injury or death can occur
if this grounding is not properly supplied.
SHOCK HAZARD
HIGH VOLTAGE is used in the operation of this equipment. DEATH ON
CONTACT may result if personnel fail to observe safety precautions. Learn
the areas containing high voltages in each part of the equipment. Be careful
not to contact high voltage connections when installing or operating this
equipment.
CHEMICAL HAZARD
Solvents used to clean parts are potentially dangerous. Avoid inhalation of
fumes and also prolonged skin contact.
