mation and during this initialization process the following
“–” is shown that indicates the “Not-yet-decided” status.

3. In this mode, even if the speci
fi
ed time has passed, the
backup memory items are not written into E2PROM.
4. This mode is cancelled by resetting. (The last screen will
not be retained.)
(Note)
In this mode, the DC error detection display, “Pro-
tect” is not shown.
Do not touch any key in this mode (while in clearing).
Never turn ON or OFF in this mode.
●
Clearing DC offset error detection information
(Clearing E2PROM data within the front end)
1. Press and hold [ATT] and [AUD] keys and reset-start to
go into the DC offset error display mode.
(While “----” is being displayed, power can be ON for 30
minutes.)
2. While in STANDBY source, the current DC offset error
detection condition is displayed.
Upper
row
DC offset error detection display 1 (To show such detec-
tion as the improper connection, and other detection)
(Display) DC1_ OK__ (not detected)
ERR
(
Improper connection or other error
is detected.)
Middle
row
DC offset error detection display 2 (To show the number
of capacitor leaks.)
(Display) DC2_ 0___ (not detected)
1
(Leak is detected once.)
2
(Leak is detected twice.)
3
(Leak is detected 3 times.)
4
(Leak is detected 4 times or more.)
3. While the DC offset error detection condition is being
displayed as above, press and hold [1] key for 2 seconds
to clear the information about the improper connection,
and other detection. Press and hold [2] key for 2 seconds
to clear the information about the number of capacitor
leaks. (Clear E2PROM)
4. DC offset error display mode is cancelled by resetting.
(The last screen will not be retained.)
(Note)
In this mode, the DC offset error detection display,
“Protect” is not shown.

How to enter the forced POWER ON mode
While “_ _ _ _” is being displayed, while simultaneously
pressing [FNC] key and [ ] key, press [RESET] button,
With this, it is possible to turn the power on for 30 min-
utes only.
