SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
- This device includes a self-diagnosis function.
- In case of abnormalities, the 1-On/ standby
the 1-On/ standby
indicator automatically blinks. It is possible to
predict the abnormality location by the number of blinks. The Instruction Manual
describes blinking of
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 1-On/ 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 malfunctions occurred.

The 1-On/ standby indi cator blinking display is released by removing the plug from
the power.
4. 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.
