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 13.
3. If an Error 5 “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. Reach under the display console and disconnect the interconnect cable.
See Diagram 5.1.
