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.
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. Radiated RF power is a potential health hazard. Observe general
safety precautions for handling high voltage equipment. Always
disconnect power before attempting any repairs.
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.
Chemical Hazard
Dry cleaning solvents for cleaning parts may be potentially dangerous.
Avoid inhalation of fumes or prolonged contact with skin.
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 if this grounding is not properly supplied.
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.

NOTE: Calls attention to supplemental information
Fuse Replacement
Always use the same type and rating of fuse when replacing the fuse.
Fuse information can be found in the parts list on page 30.
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.
CAUTION
Caution notes call attention to a procedure which, if not correctly
performed, could result in damage to the instrument.
The caution symbol appears on the equipment
indicating there is important information in the
instruction manual regarding that particular area.
WARNING
Use only NIckel Metal Hydride (NiMH) batteries that have a minimum
capacity of 4600 milliamper hours (mAh). Do not install batteries that are
not Nickel Metal Hydride. Do not install NiMH batteries that have less
than 4600 mAh capacity. Failure to comply may result in damage to the
batteries, damage to the instrument, and injury to personnel from battery
chemicals.
WARNING
Use dry cleaning solvents in a well ventilated area. Avoid excessive
inhalation of solvent fumes, since they can be toxic in heavy concentrations.
Always wear eye protection and avoid skin contact with the solvent.
WARNING
Be sure that the power cable is unplugged before opening the wattmeter
case. The power supply capacitor, C1, can retain a dangerous charge that
must be removed before touching. Always have another person standing by
who is trained in electric shock first aid.

Caution Statements
The following equipment cautions appear in the text whenever the
equipment is in danger of damage, and are repeated here for emphasis.
CAUTION
Long-term storage of this instrument can affect battery performance and
reduce battery life. Do not store the instrument for long periods of time
without recharging the batteries (refer to page 19). Failure to comply may
result in reduced battery charge and shortened battery life.
CAUTION
If the element cannot be fully inserted into the socket, do not force
it. You might damage the element.
CAUTION
Internal batteries are connected. Remove one of the battery tubes before
unsoldering wires connected to the Main PCB. Failure to comply may result
in permanent equipment damage and severe shock to individuals.
CAUTION
Never apply RF power to the Model 4391A Wattmeter unless both line
section sockets are filled with either an element or a dust plug. If an
element is used it is advisable to place the element with the arrow at a 90°
angle to the coaxial line.
CAUTION
Always be certain the 115/230 voltage selector is set to the proper voltage
before ac power is applied.
CAUTION
Always disconnect AC power before opening the Model 4391 enclosure.
Removal of at least one battery cell is also recommended when servicing the
instrument.
CAUTION
This instrument contains static sensitive electronic components. Before
opening or servicing the unit, make sure that you understand and practice
electrostatic discharge component handling. Failure to comply may result
in permanent damage to sensitive components.
