JCM Gold G215 - I had the CCCC problem but now have no display at all. ?
As above - I tried to fix this by turning it off, turning the key to program and holding down the #1 3 7 and 9 keys simultaneously. Turned the power back on and it moved the till roll on. Then I held down #1 and Clerk ID and turned the key back to register. I now have no display at all. Any ideas?
Sounds like the battery is faulty. Make sure it gets changed every four years. If you want to change it yourself and clear the error, the G215 service manual is here:
