KV-XA21M8J/XA21MSJ RM-952 SELF DIAGNOSTIC FUNCTION The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp flash indicators is listed in the instruction manual for the user’s knowledge and reference.
