How do I reset/restore factory defaults?

To restore the PCM91 to its default state without erasing registers:
– Enter the CONTROL MODE by pressing 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 91 will display the message “Setup restored”.

The following procedure will return the PCM91 to the factory defaults. This includes erasing all user registers and setups, as well as restoring all default settings.
– Enter the CONTROL MODE by pressing Control.
– Use the Up and Down buttons to locate Row 1 System.
– Turn SELECT to 1.9 Initialize.
– Press Store. The PCM 91 will display the message “Are you sure? (Press STORE)”.
– If you do not want to reinitialize, press any button EXCEPT Store or if you want to proceed with reinitialization, press Store in response to the message. The display will flash the message “Restoring original factory settings” and your unit will be reinitialized.
