1. Go into your utilities menu by selecting the [edit button]->[menu mode]->rotate the page until you see utility. Select enter and rotate the page dial until you see clear System. Select enter and enter again. Wait a couple of seconds and you should get a “System Cleared” message. Try your pedal and see if it is functioning again. If that doesn’t solve it try step 2.
2. Start with the unit powered off (unplugged)
Now, Press and hold the “COMP” and “FILTER” button at the same time, while powering the unit back on.
Once the screen shows the version number and a screen like this “X0X0 X27″ it should start to numeric count up and reset in approx 3 minutes.
