Hi, I have one of these that shows an error code: U2-23, a memory error that can be reset with sim 16, problem is that it doesn't seem to have the same code to get into diagnostics as the older AR-M355/455 which used Program * Clear * !! I've servicing this as a like machine to the AR-M355 ... anyone know the correct Sim Code or Diagnostics code ??
Thanks, Mike
