MAINTENANCE AND SERVICE
Cleaning the Unit
We recommend that you clean the AMX−4+ regularly with a soft cloth and a mild,
non−abrasive cleaner. Apply the cleaner to the cloth, not directly to the unit, to safe-
guard against damage to the circuitry. If a corrosive chemical is spilled or splashed on
the unit surface, be sure to clean it off immediately.
Main Power Circuit Breaker
The main power circuit breaker is located on the front right side of the unit. Refer to
Illustration 6−3.
If the battery charge is too low, or in the event of an overload in the high−voltage sys-
tem, the circuit breaker will
trip
(interrupt power to the x−ray unit).
Should the circuit breaker trip, the control panel lights will go out and you’ll be pre-
vented from operating the unit. To resume operation, flip the circuit breaker up to the
ON
position.If necessary, recharge the unit or (if the battery is adequately charged) try
the procedure again.
If the battery is within operating condition (as indicated by the battery status and mes-
sage displays) and power interruptions are frequent, there may be a fault in the high
voltage system. If a fault is indicated, have the unit checked by a qualified service rep-
resentative.
If the unit does not turn off when the keyswitch is turned off, isolate the unit to prevent
unauthorized operation, use the circuit breaker to remove power from the unit, and
have the unit checked by a qualified service representative.
Periodic Maintenance by
Service Personnel
To insure the continued safe performance of your AMX−4+ portable x−ray unit, es-
tablish a periodic maintenance program with a qualified service representative.
Periodic maintenance checks are required thirteen months after installation and every
year thereafter. A periodic maintenance schedule and a sample mAs/kVp accuracy
chart are provided on the following pages.
