Figure 6-5. Press [D] to run the test or [C] to go back to the previous menu.
NOTE:
Due to operational variables, it is possible to get false indications which place a
fault in the log and abort the test. If the System Test fails, note the fault in the
Fault Log, clear the fault log, and run the test again to verify the problem.

NOTE:
Predicted time indicated is approximate only and may vary.
This test should be used as part of a routine maintenance program at least once a year. It
should also be done if major combiner components are removed and/or replaced, such
as a Z-Plane or Isolation Board or if cabling is disconnected and re-connected to the Z-
Planes or Isolation Boards.
The following sequence of tests make up the SYSTEM TEST:
• PA Muting Test
• PA ISO Resistor and Thermistor Test
• PA RF Switch Test
6.10.1.1 PA Muting Test
Each PA will be muted for 1 second, one at a time. The controller then checks the
current draw of each PA, which should be close to zero. If it finds a PA that is drawing
too much current while it is supposed to be muted it will abort the test and report an
A#_MUTE_FLT, B#_MUTE_FLT, C#_MUTE_FLT or D#_MUTE_FLT. For more
information refer to PA MUTE Faults later in this Section.
