When the Coupler BITE test routine finishes, one of the following messages will appear in the Operational
Display. The following summarizes these messages and their meaning.
• ‘SELECT BITE TYPE’. This message means the Antenna Coupler successfully tuned all three (3) test
frequencies.
• ‘NO TUNE AT XX XX MHZ’. This message means the Antenna Coupler tuned all test frequencies
successfully prior to the one currently indicated as “No Tune”. In this case, XX XX indicates the
specific test frequency. The decimal point is not displayed.
If a “No Tune” message 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 the Coupler BITE test. Depressing the ‘CU-BITE’ key again at 4 as shown in Figure 7.3.3.2
will cause the Coupler BITE test routine to repeat.
• Repeat the Transmit BITE or Receive BITE tests, as previously covered.
• Exit BITE mode. Depressing the ‘END’ key at 3 will return to the main menu and resume normal
operation.
