MAINTENANCE
This equipment requires very little maintenance due
to its solid-state circuitry.
However,
a program of
periodic preventive maintenance should be initiated.
This should include regular inspection, general clean-
ing, transducer face inspection, overall system
performance checks,
and standard good-housekeeping
practices.
A periodic inspection of the transducer is recommended
in some applications,
at which time any build-up of
material on the transducer face should be removed.
WARNING:
TURN POWER OFF BEFORE ATTEMPTING TO CLEAN CHASSIS.
The chassis is best cleaned with a vacuum cleaner or
a clean,
dry cloth.
Remove all layers of accumulated
dust from printed-circuit board components. Check all
electrical contacts for corrosion and wear.
