SELF DIAGNOSIS FUNCTION

1. Summary of Self-Diagnosis Function

-This device includes a self-diagnosis function.

-Incaseofabnormalities, the POWER/STANDBY indicator automatically blinks. It is
possible to predict the abnormality location by the number of blinks. The Instruction
Manual describes blinking of the POWER/STANDBY indicator.

-Ifthe 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 POWER/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 lowe
blink count blinks first.

-The screen display displays the results regarding all the diagnosis items listed below.

Thedisplay "0" means that no malfunctions occurred.
