Procedure 6.2 - 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.
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. If the EFX powers up and functions normally until a particular key(s) is pressed, skip to step
10. If a "STUCK KEY" message is immediately displayed when the EFX is powered up,
continue with the next step.

switch in the "off" position. Remove the display bracket cover from the rear of the display.
Disconnect heart rate cables. Disconnect the data cable from the Upper PCA. See Diagram
6.2.
4. Remove the three screws that fasten the accessory tray to the upper portion of the display.
Remove the four screws that fasten the display housing front panel to the display housing
back panel.
5. Lift the display housing front panel off of the display housing backing plate. Remove the
