When the DIGITAL P.C.B. or IC224 on DIGITAL P.C.B. is replaced, this unit will display “Internal Error” and will not
operate properly. The model name and destination MUST be written to the backup IC (EEPROM: IC224 on DIGITAL
P.C.B.) to have proper operation. (For detailed procedure, refer to related Service News or Service Bulletin. Or
contact your local Yamaha representative.)
注意:

■ SERVICE PRECAUTIONS / サービス時の注意事項
Safety measures
• Some internal parts in this product contain high
voltages and are dangerous.
Be sure to take safety measures during servicing, such
as wearing insulating gloves.
• Not e that the cap aci tor s ind ica ted b elo w are
dangerous even after the power is turned off because
an electric charge remain s and a high voltage
continues to exist there.
Before starting a
resistor (5 k-ohms/10 W) to the terminals of each
capacitor indicated below to discharge electricity.
The time required for discharging is about 30 seconds
per each.

written one after updating, perform the updating
procedure again from the beginning.
● Initializing the back-up IC (EEPROM: IC224 on DIGITAL P.C.B.)
After updating the firmware, the back-up IC MUST
be initialized by the following procedure store the
setting information (soundfield parameters, system
memory and tuner presetting, etc.) properly.
Start up the self-diagnostic function and select “S3.

If the protection function works and causes hindrance
to troubleshooting, cancel the protection function by
the procedure below, and it will be possible to enter the
s
elfdiagnostic function mode. (The protection functions
other than the excess current detect function will be
disabled.)
While pressing the “TONE CONTROL” and “INFO” keys,
press the “z” (Power) key to turn on the power and keep
pressing those 2 keys and “z” (Power) key for 3 seconds
or longer.
The self-diagnostic function mode is activated with the

CAUTION!
Using this unit with the protection function disabled may
cause further damage to this unit. Use special care for
this point when using this mode.
