If a Transmitter Module BITE Fault is found
The following actions will typically occur when a Fault is found:
1. The Transmit BITE (‘TX - BITE’) test routine will halt.
2. A Module Fault message will be displayed at 4 in the Operational Display .
3. The Red ‘FAULT’ lamp on the Front Panel at 5 will be lit.
Proceed to Section V of this manual for fault isolation and repair procedures.
If the Transmit BITE test routine finishes without displaying a Fault message, one of the following messages
will appear in the Operational Display. The following summarizes these messages and their meaning.
• ‘TEST COMPLETED’. This message means all Transmitter Modules passed the Transmit BITE test
routine. It also means that the Antenna Coupler successfully tuned all eight (8) test frequencies.
• ‘NO TUNE AT XX XX MHZ’. This message means all Transmitter Modules passed the Transmit BITE
test routine but a “No Tune” condition was found on one test frequency. In this case, XX XX indicates
the specific test frequency. The decimal point is not displayed.
• ‘NO TUNE AT MULT MHZ’. This message means all Transmitter Modules passed the Transmit BITE
test routine but a “No Tune” condition was found on two (2) or more of the test frequencies
If either of the “No Tune”-related messages appears, proceed to Section V of this manual AND the Antenna
Coupler manual for fault isolation and repair procedures.
After this test is completed, the User may do the following:
• Repeat this Transmit BITE test. Depressing the ‘TX-BITE’ key again at 2 as shown in Figure 7.3.3.2
will cause the Transmit BITE test routine to repeat.
• Repeat the Receive BITE test, as previously covered.
• Exit BITE mode. Depressing the ‘END’ key at 3 will return to the main menu and resume normal
operation.
• Proceed to the Coupler BITE (‘CU-BITE’) test routine covered in the following section.
