This usually happens after a lightning hit or a power surge. 

How to

  1. Go to the processor (EMAP) and do a deep clear (this will not erase your presets).
  2. Jumpers 7 and 8 at location J3 allow you to clear the EMAP’s memory (normally saved by a back-up battery).
  3. Set both jumpers to on and press the [Reset] button.
  4. The EMAP flushes out its memory and resets itself completely.
  5. Remove both jumpers and press [Reset] again to return the EMAP to active statusEMAP.jpg
