4.4.5 Manipulate after detect DC Offset
• If detected error 10 consecutive times, and 10th error occurred
in "Mis-connect detection period", judge as "Mis-connect".
• If detected error 10 consecutive times, and 10th error occurred
in "Capacitor leak detection period", judge as "Capacitor leak ".
• If detected error 10 consecutive times, and 10th error occurred
in "Other detection period" and detected another 10 errors con-
secutively, then judge as "Other".
• If judge as "Mis-connect".
- turn off speaker output.
- display "MISWIRING", check wiring connection then reset.
- key access disable except button of Eject, Reset and service
mode
- record error in EEPROM "DC1 ERR"
- the product is able to be recovered by Reset button.
• If judge as "Capacitor leak ".
- turn off speaker output.
- display "WIRING", check wiring connection then reset.
- key access disable except button of Eject, Reset and service
mode
- record error in EEPROM "DC2 #" (# means counter number)
- the product can be recovered by pressing the Reset button
before the capacitor leak error counter reach "DC2 4".
After that, only clear the counter back to "0" can recover the
product.
• If judge as "Other" (manipulation same as mis-connect)
SECTION 5
TROUBLESHOOTING
5.1
How to cancel DC offset error
Check to be sure the terminals of the speaker leads are covered
with insulating tape properly, then reset the product.
If an error message does not disappear even after a reset, there
is a need for internal repair.
5.2
How to clear DC offset error recorded in EEPROM
Refer to “4.2.2.5 ERROR/DIAG DATA”.
