PM4 Troubleshooting

Buttons Not Working

Symptom 1

The monitor powers up and displays information, but one or more of the buttons on the monitor face (usually the Menu or Menu | Back button) do not work.

Resolution 1

This is a hardware issue, usually caused by corrosion on the circuit board. The PM must be replaced.

Symptom 2

Not all buttons on the monitor face power up the monitor. Only pressing certain buttons or rowing/skiing will power up the monitor. After the monitor is on, some buttons may not work unless pressing hard.

Resolution 2

The keypad may be aging or worn and cannot make the connection. The PM3/PM4 keypad, part number 1451, should be replaced. See also:
