SECTION 1
SELF DIAGNOSIS FUNCTION
The unit 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. 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 an errors 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".
