ApexPro Transmitter
If any test has failed:
1. Select the Set Frequency button, reference B in “Program ApexPro
Transmitter Window” on page 59.
2. Check the Clear Failures With This New Setting box.
If any tests fail again, see “Power-Up Self-Test Failures” on page 77.
Diagnostic Tests
Diagnostic tests (reference D in “Appendix 2: Access ApexPro Technical
Functions” on page 79) run at all times but are accessible only by personnel
authorized for high-level functions. The results shown are:
 Battery voltage – the specific combined voltage of the two AA batteries in
the transmitter. Each AA battery is nominally rated at 1.5V, so two fresh
batteries together should register at 3.0V. The lowest total voltage for
the transmitter to operate properly is approximately 1.5V.
 Battery Status – the relative strength of the AA batteries in the
transmitter, ranging from zero (dead) to 7 (full power).
 Lead Status – the status of any leads connected to the transmitter. Since
the transmitter is connected to the programming device and not to any
leads, the status during the programming process will always be “3F”,
indicating no leads attached.
 Button status – indicates which buttons on the transmitter are being
pressed. You can use this to test the buttons if you suspect they may be
stuck.
 0 = Both Verify Leads and Graph buttons are pressed.
 1 = Verify Leads button is pressed.
 2 = Graph button is pressed.
 3 = Neither button is pressed.
