SELF DIAGNOSIS FUNCTIONS

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.

DIAGNOSTIC TEST INDICATORS

When an error occurs, the STANDBY LED will flash 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 first of the problem areas. 

Result for all of the following diagnostic items are displayed on screen. 

If the screen displays a “0”, no error has occurred .
