Coping with backup current measurement
• Regardless of the Test Mode, when reset in the ACC OFF
state (backup ON), MUTE will be OFF after two seconds.
(The power for peripherals will not be turned OFF until the
CD mechanism stops. This will take two seconds plus.)
Forced clearing of DC offset detection
• Regardless of the Test Mode, when power is turned on by
[SRC] key while depressing the following keys. This will be
the forced clearing of DC Err condition in the EEPOM. This
will clear the data in the EEPROM even in the case where
there is no error data.
• Key Operation
Press the [SRC] key while pressing the [DISP] and [EQ]
key at the same time.
