Summary of Self-Diagnosis Function
•
This device includes a self-diagnosis function.
•
In case of abnormalities, the
1
indicator automatically blinks. It is possible to predict the abnormality location by the number
of blinks. The Instruction Manual describes blinking of the
1
indicator.
•
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was gener-
ated 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
1
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.
