9. Troubleshooting
This table is a list of troubleshooting tips specific to the AIB module. For
additional troubleshooting tips, refer to the troubleshooting section found in the
Monitoring and Control Network System Manual, reference 1.
Due to the high percentage of surface-mount components the AIB is treated as a
field replaceable unit. If any system problems are the result of a malfunctioning
AIB unit, the entire unit must be replaced and returned for repair.
PROBLEM CAUSE
User Interface
Module is not
showing a disabled
receiver when the
receiver is disabled
at the ASTRO-
TAC™ Comparator This is normal. If Motorola’s RSS (Radio Service Software) is
used to disable a receiver, the ASTRO-TAC™ Comparator does
not send that information to the AIB. The MCN comparator
display system will not show that receiver as being disabled, even
though it truly is disabled in the comparator.
User Interface

AIB Verify that the AIB is properly connected to the comparator.
Verify that the AIB’s OPTION A, switch 8 is set for the proper
comparator type. If not, change the switch and reset the AIB.
