SELF-DIAGNOSTIC FUNCTION
If an error occurs, the TIMER 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 definition of the TIMER LED 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.
