SELF-DIAGNOSTIC FUNCTION
Self Diagnosis
Supported model
The units in this manual contain a self-diagnostic function. If an error occurs, the TIMER/PIC OFF LED indicator will automatically begin to fl ash. The 
number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the TIMER/PIC OFF LED fl ash 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. Diagnostic Test Indicators
When an error occurs, the TIMER/PIC OFF LED indicator will fl ash a set number of times to indicate the possible cause of the problem. If there is more 
than one error, the indicator will identify the fi rst of the problem areas.
