Preventive Maintenance
To avoid unnecessary damage, always observe the following
cautions:
1. The RF Power Analyst is a rugged and portable instru-
ment intended for field use. However, it should not be
unnecessarily exposed to extreme environmental condi-
tions.
2. When not in use, store the RF Power Analyst with the
LINE/OFF/BATT switch is in the off position.

of the RF Power Analyst. Refer to “Battery Care” on
Cleaning and
Inspection
Perform a periodic inspection to ensure that the RF power
analyst is always operational. Any damage noticed during
inspection should be listed and repaired before use.
1. Visually inspect the equipment for loose or damaged
parts.
2. Wipe dust and dirt from the front panel and lower hous-
ing. Remove stubborn dirt with mild detergent and a
soft cloth.
3. Clean the inside of the line section bores using cotton
swab stick dampened with alcohol.
4. Visually inspect the RF connectors for any sign of wear
or damage and replace if necessary. Clean the connec-
tors with alcohol or any acceptable dry cleaning fluid.
Long-term
Storage
Do not store the instrument for long periods of time without
recharging the batteries. When the instrument is stored for
long periods of time without use, the batteries will loose
their charge and also loose the ability to reach full charge
when put into service. To restore the battery charge, perform
a full charge for 16 hours. If the batteries are not fully
charged after 16 hours, completely discharge the batteries
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.
