To reset the factory presets only (01-49), follow this procedure:

•Turn all pots counter-clockwise to minimum.
•Press and hold the Up and Down buttons simultaneously, while turning the
power switch back on. The display will show “Fr” to represent Factory reset.
•Continue to hold the Up and Down buttons for 3 seconds.
•When reset, the display will show “00” to indicate you’re in Program 00, bypass.
That’s it. Factory preset Programs 01-49 are back to how the unit was originally shipped.

Если же PSA 1 - тогда так:
GLOBAL RESET
If you want to completely reset your unit back to factory specifications, follow this procedure:
Unplug the unit’s power cord. Turn all pots all the way counter-clockwise to minimum. Push the
Up and Down buttons simultaneously, while re-plugging the power cord back into an AC outlet.
The two dots in the upper left hand corner of the display will light up. Release the Up and Down
buttons. Wait approx. 10 seconds for the dots to go dark. The display will show 00. That’s it.
You’re back to how the unit was originally shipped
