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
1. On C846 version 1 units, 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. If an error 5 is being displayed, continue with step 3. If one or more keys do not function,
skip to step 8.
3. 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.
4. Attach the wrist strap to your arm, then connect the grou nd lead of the wrist strap to an earth
ground.
5. The C846 version 1 upper PCA is pictured in the illustrations, but the procedure is the same
for the C842, C846i and all C846 bicycles.
6. With the power off (not pedalling), disconnect the keyboard cable from the upper PCA.
