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 applied to all phases of operation and maintenance.
Keep Away From Live Circuits
Operating personnel must at all times observe normal safety regulations.
Do not replace components or make adjustments inside the equipment
with high voltage turned on. To avoid casualties, always remove power.
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is
present.
Do Not Service Or Adjust Alone
Under no circumstances should any personnel 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.
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
conductor power cable is not sufficient protection. Serious injury or death
can occur of this grounding is not properly supplied.
Chemical Hazard
Dry cleaning solvents for cleaning parts may be potentially dangerous.
Avoid inhalation of fumes or prolonged contact with skin.
Resuscitation
Personnel working with or near high voltages should be familiar with
modern methods of resuscitation.

Safety Symbols
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.
This symbol indicates that a shock hazard exists if the
precautions in the instruction manual are not follwed.
The caution symbol appears on the equipment indicating
there is important information in the instruction manual
regarding that particular area.
This symbol indicates that the unit radiates heat and
should not be touched while hot.
NOTE: Calls attention to supplemental information.
Warning Statements
The following safety warnings appear in the text where there is danger to
operating and maintenance personnel and are repeated here for emphasis.
WARNING
BOTH vent plugs must be used at all times when the unit is operating
or cooling. Failure to do so could result in an explosion or severe burns.
WARNING
Disconnect the unit from all power sources before servicing.
The unit may be energized from multiple sources.
The potential for electric shock exists.
WARNING
Never attempt to connect or disconnect RF equipment from the
transmission line while RF power is being applied.
Leaking RF energy is a potential health hazard.
ii
Caution Statements
The following equipment cautions appear in the text whe
never the
equipment is in danger of damage and are repeated here for emphasis.
CAUTION
This load is
designed for operation in a horizontal position only, with
the vent plugs up. Do not use in any other manner.
CAUTION
If installed, connect optional interlock before applying RF power.
CAUTION
Use only Bird coolant, P/N 5-1070, to prevent damage to the load.
