Procedure 5.1 - 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.

Procedure

1. Set the circuit breaker in the “off” position.

WARNING

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

Section One of the Commercial Treadmill Service Manual.

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

step 11.

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

continue with the next step.

4. This condition may be caused by either the keypad or upper PCA. Set the circuit breaker in

the “off” position.

5. 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.

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

keypad connector from the upper PCA. See Diagram 5.1.
