SELF DIAGNOSIS FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED will automatically begin to flash. The number
of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY 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.

one error, the LED will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen.
