Troubleshooting
The service technician performs troubleshooting whenever a failure occurs during normal
operation that cannot be resolved by the RF-Conductor! (RF-C!) controller.
This troubleshooting section is a guide to isolating failures to a FRU level. Replace the
suspected FRU with a working FRU and contact the local Motorola Service Center for repair.
After replacing the FRU, perform the RF-Baton! (RF-B!) transmitter controller power-up
checkout procedure to verify that the failure clears (see Chapter 4, "Installation", paragraph,
"Powering Up the System").
Front Panel Indications
Table 6-1 provides information about front panel indications, possible failures, and corrective
actions. The index lists several possible failures and corresponding corrective actions for some
indications. If a failure is isolated to a FRU, replace the defective module with a working unit
and contact the Motorola Paging One-Call-Support Center for repair.
