NOTES: If the FIL lamp comes on, refer the AM-6545 to higher maintenance.
If the AM-6545 bandswitch rotates continually, remove power and replace the
AM-6545.
If the equipment shuts down during operation, check for overvoltage (above
32 v DC), check CB1 and CB2 (overload), and check the louvers of the AM-6545
and CU-2064 for clogging (overheat).
The RT-1209 is the component most likely to fail.
Therefore, it should be
the component suspected first.
