​Question:

How do I factory reset my Lexicon PCM 70?

​Answer:

Warning: this will erase all user presets and settings.

1. Turn off the power switch for a few moments, then turn it back on.  When the software version number appears on the display, press the 0 key.
2. After a few moments, you will be asked: CLEAR MEMORY?
3. Press the LOAD key.  You will be asked: ARE YOU SURE?
4. Press the 1 key.  The PCM70 will briefly flash: CLEARING MEMORY and then load program 0.0.  All registers will be erased and all control parameters will be returned to factory presets​
