   RM-GA001
The unit in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically
begin to flash.
The number of times the LED flashes translates to a probable source of the problem. A defination of the STANDBY/TIMER
LED flash indicators is listed in the intruction 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
When an error occurs, the STANDBY/TIMER LED will flash a 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.
SECTION 1
SELF DIAGNOSTIC FUNCTION
*
If a +B overcurrent is detected, stoppage of the vertical detection is detected simultaneously. The symptom that is
diagnosed first by the microcontroller is displayed on the screen.
**
Refer to screen (G2) adjustment (fine adjustment) in section 2 of this manual.
***
Is STANDBY/TIMER LED flashes six (6) times, unplug the unit and wait 10 seconds before performing the adjustment.
