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.
1-1. DIAGNOSTIC TEST INDICATORS

to be abnormal.
*2: If abnormal temperature of BH board occurs, STANDY LED flashes is same as abnormal temperature inside unit, the error is
differentiated by shot unit down or not. When the unit shut down, abnormal temperature inside unit occurs.
*3: No item on screen display
