Procedure 6.2 - Troubleshooting the Keypad and Upper PCA
If the function keys on the electronic console are unresponsive, the problem may be either the
upper PCA or keypad. The keys on this unit are touch sensitive keys. It is necessary to use the
keypad diagnostics to troubleshoot the key functions.
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in
Section One.
1. Attach the anti-static wrist strap to your arm, then connect the ground lead of the wrist strap
to the units frame.
2. If the EFX powers up and functions normally until a particular key(s) is pressed, skip to step
12.
3. If a “stuck key” message is immediately displayed when the EFX is powered up, continue
with the next step.
4. This condition may be caused by either the keypad or upper PCA.
5. Remove the five screws that fastens the display housing front panel to the display housing
backing plate. These screws are located on the rear of the display housing backing plate.
6. Lift the display housing front panel off of the display housing backing plate. Remove the
keypad connector from the upper PCA. Refer to Diagram 6.3.
