4. SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as power sometimes shuts offor screen sometimes goes outthat cannot be confirmed, it
is possible to bring up past occurances of failure for confirmation on the screen:
[To Bring Up Screen Test]

[Screen display] / channel [5] / Sound volume [-] / Power ON
˘
Note that this differs from entering the service mode (mode volume [+]).
Self-Diagnosis screen display
SELF DIAGNOSTIC
002 : 000
003 : 000
004 : 000
005 : 001
101 : 000
Numeral "0" means that no fault has been detected.
Numeral "1" means a fault has been detected.
5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen
during repairs. When you have completed the repairs, clear the result display to 0.
Unless the result display is cleared to 0, the self-diagnostic function will not be able to detect subsequent faults after
completion of the repairs.
[Clearing the result display]
To clear the result display to 0, press buttons on the remote commander sequentially as shown below when the diagnostic
screen is being displayed.
Channel [8] / 0
[Quitting Self-diagnostic screen]
