Monitor the Status of Transmitter Tests
Transmitter tests run whenever the transmitter is powered up. You can view
the test results with the Apex & ApexPro Tx Config software. The results
shown indicate pass-or-fail status for these tests:
 ROM — Read-Only Memory. If this test fails, the ROM needs to be
replaced.
 RAM — Random-Access Memory. If this test fails, the RAM needs to be
replaced.
 EEPROM Checksum — Indicates whether the transmitter firmware is
valid or is corrupt.
 Synthesizer Lock — Shows the current status of the phase lock loop in
the transmitter. This indicates whether or not the transmitter is
operating at its programmed frequency. Failure of this test indicates that
this transmitter could be operating at a different frequency and could be
causing interference with another transmitter programmed to that other
frequency. If this is the case, this transmitter should be removed from
service until the problem is corrected. Refer to “Test Status Failures” on
page 30.
If any test has failed:
1. Access the high-level technical functions of the software as described in
“Access the Super User Mode” on page 31.
2. Select the Clear Failures button (reference E in “Program Apex
Transmitter Technical Functions Window” on page 31.)
If any tests fail again, see “Appendix 1: Apex Troubleshooting” on page 29.
