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 thoroughly understood and apply to all
phases of operation and maintenance.
Safety Symbols
The caution symbol appears on the equipment indicating there is
important information in the instruction manual regarding that
particular area.
Note: Calls attention to supplemental information.
WARNING
Keep Away From Live Circuits
Operating Personnel must at all times observe general safety precautions.
Do not replace components or make adjustments to the inside of the test
equipment with the high voltage supply turned on. To avoid casualties,
always remove power.
WARNING
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is present.
WARNING
Do Not Service Or Adjust Alone
Under no circumstances should any person reach into an enclosure for the
purpose of service or adjustment of equipment except in the presence of
someone who is capable of rendering aid.
WARNING
Safety Earth Ground
An uniterruptible earth safety ground must be supplied from the main
power source to test instruments. Grounding one conductor of a two
conductor power cable is not sufficient protection. Serious injury or death
can occur if this grounding is not properly supplied.
WARNING
Chemical Hazard
Dry cleaning solvents for cleaning parts may be potentially dangerous. Avoid
inhalation of fumes or prolonged contact with skin.
WARNING
Resuscitation
Personnel working with or near high voltages should be familiar with
modern methods of resuscitation.
WARNING
Remove Power
Observe general safety precautions. Do not open the instrument with the power on.
WARNING
Warning notes call attention to a procedure which, if not correctly
performed, could result in personal injury.
CAUTION
Caution notes call attention to a procedure which, if not correctly performed,
could result in damage to the instrument.
