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.
