SELF-DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to ß ash. The number
of times the LED ß ashes translates to a probable source of the problem. A deÞ nition of the STANDBY/TIMER LED ß 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.

Diagnostic Test Indicators
When an error occurs, the STANDBY/TIMER LED will ß ash a set number of times to indicate the possible cause of the problem. If there is more than
one error, the LED will identify the Þ rst of the problem areas.
