6.2.4 BIT Troubleshooting
BIT is executed from the KDU of the RF-5800H-MP connected to the RF-5800H 125-Watt Communication
System, or from an optional terminal connected to the RF-5800H-MP. The self-test function of the RF-5800H-MP
automatically tests the system. If a problem is located, a fault code is displayed on the KDU display.
See Figure 6-2 for a sample fault code displayed on the KDU. Table 6-2 is a list of the BIT fault codes. Next to
each fault code is a recommendation of which assemblies may have caused the fault. Remove and replace the
recommended LRUs one at a time in the order listed, executing BIT after replacing each LRU. Paragraph 2.5
includes the LRU removal and installation procedures. If the unit passes BIT, the faulty LRU has been isolated.
If replacing the suspected LRU does not correct the problem, refer to Paragraph 6.3.2, the troubleshooting index,
for additional troubleshooting recommendations.
