Procedure 6.2 - Troubleshooting the Keypad
If the function keys on the electronic console are unresponsive, the problem may be either the
upper PCA or keypad. This troubleshooting procedure gives you the information you need to
determine which of these components is malfunctioning.
Procedure
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in
Section One.
1.
If an error 5 is being displayed, continue with step 3. If one or more keys do not function,
skip to step 8.
2.
Remove the screws that secure the upper display assembly to the upper handrail. Carefully,
pull some excess interconnect cable out from the targa upright. Rotate the display housing,
so that the rear of the upper PCA is facing upward, and set the display housing on the upper
handrail.
3.
Attach the wrist strap to your arm, then connect the ground lead of the wrist strap to an earth
ground.
4.
With the power off (not pedalling), disconnect the keyboard cable from the upper PCA.
5.
Start pedalling, if the error 5 is no longer present, the key board is bad. If the error 5 is still
present, the upper PCA is bad. Replace either the keyboard (display housing) or the upper
PCA as appropriate.
6.
Substitute a known good keyboard (display housing) to determine if the keyboard is
defective. If the keys not function normally, replace the original keyboard (display housing).
If the same key(s) still do not function, replace the upper PCA.
7.
If you have performed all of the previous tests and have not been able to locate the trouble,
call Precor customer support.
8.
The only means of determining if a non-functioning key is caused by the keypad or the
upper PCA is by substituting a known good part. The keypad is the more likely cause, try
substituting the display with keypad before the upper PCA.
9.
If you have performed all of the previous tests and have not been able to locate the trouble,
call Precor customer support
