The units in this manual contain a self diagnostic function. If an error occurs, the STANDBY (1) indicator will
automatically begin to flash. A description of the self-diagnosis function is explained in the instruction manual. The
number of times the STANDBY (1) indicator flashes translates to a probable source of the problem. 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. DIAGNOSTIC TEST  INDICATORS
When an errors occurs, the STANDBY (1) indicator will flash a set number of times to indicate the possible cause of
the problem. If there is more than one error, the indicator will identify the first of the problem areas.

"0".
*
If a +B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is
diagnosed first by the mirco controller is displayed on the screen.
** Refer to Screen (G2) Adjustment in this manual.
