Troubleshooting

You can restore the PCM 80 to its default state without erasing registers by
restoring the factory default setup:

Press Control.

Use the Up and Down buttons to locate Row 4 Setup.

Turn SELECT to 4.1 Load.

Turn ADJUST counterclockwise to select "Factory Settings".

Press Load/

✱

. The PCM 80 will display the message "Setup restored".

The following table shows the parameters which comprise a setup, along with
the factory default setting of each parameter.
