SECTION 1
SELF DIAGNOSIS FUNCTION
The unit in this manual contain a self-diagnostic function. If any 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. If an error symptom cannot be
reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems
and how often these problems occur.
1-1. DIAGNOSTIC TEST INDICATORS
When any error occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the
problem. If there is more than one error, the lamp will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.
