Power-up Self Test Status
Power-up self-tests (reference G in “Program ApexPro CH Transmitter
Window” on page 35) 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 power-up self-tests:
 Synthesizer Lock Log — Indicates fail status if the transmitter was ever
unable to operate at its programmed frequency. A single failure may be
caused by a temporary deviation. Repeated failures may indicate a
hardware problem. If this is the case, contact Technical Support. (See
“Technical Support” on page 51.)
 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 “Power-Up Self-Test
Failures” on page 50.
