Procedure 6.3 - Troubleshooting the Keypad and Upper PCA

(version 2,3)

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.

Procedure

1. Set the on/off switch in the “off” position.

WARNING

Before continuing with this procedure, review the Warning and Caution statements listed in

Section One.

2. Attach the anti-static wrist strap to your arm, then connect the ground lead of the wrist strap

to the units frame.

3. If the EFX powers up and functions normally until a particular key(s) is pressed, skip to step

12.

4. If a “key depressed” message is immediately displayed when the EFX is powered up,

continue with the next step.

5. This condition may be caused by either the keypad or upper PCA. Set the on/off switch in

the “off” position.

6. Remove the four 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.

7. Lift the display housing front panel off of the display housing backing plate. Remove the

keypad connector from the upper PCA. See Diagram 6.2.
