Blinking count display of STANDBY/ indicator
1.
Summary of Self-Diagnosis Function
•
This device includes a self-diagnosis function.
•
In case of abnormalities, the STANDBY/ indicator automatically blinks. It is possible to predict the abnormality
location by the number of blinks. The Instruction Manual describes blinking of the /STANDBY/ indicator.
•
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated
or not. Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.
2.
Diagnosis Items and Prediction of Malfunction Location
•
When a malfunction occurs the STANDBY/ indicator only blinks for one of the following diagnosis items. In case of
two or more malfunctions, the item which first occurred blinks. If the malfunctions occurred simultaneously, the item with the
lower blink count blinks first.
•
The screen display displays the results regarding all the diagnosis items listed below. The display “ 0 ” means that no malfunc-
tions occurred.

Self-diagnosis screen displays
•
In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when
the screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether
the detection circuit operated or not) in order to allow confirmation.
<Screen Display Method>
