About lead free solder /
無鉛ハンダについて
All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.
Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.

■ 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.
• Note that the capacitors indicated below are dangerous
even after the power is turned off because an electric
charge remains and a high voltage continues to exist
there.
Before starting any repair work, connect a discharging
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.
a. Remove 3 screws (⑥) and 7 screws (⑦). (Fig. 3)
b. Remove 3 screws. (⑧). (Fig. 2)
c. Remove CB21, CB82, CB87 and CB947. (Fig. 2)
d. Unlock and remove CB83, CB85 and CB948. (Fig. 2)

● Starting Self-Diagnostic Function in
the protection cancel mode
If the protection function works and causes hindrance to
trouble shoot, cancel the protection function as described
below, and it will be possible to enter the self-diagnostic
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 “MAIN ZONE
keep pressing those 2 keys for 3 seconds or longer.
The self-diagnostic function mode is activated with the
protection functions disabled.
In this mode, the “SLEEP” segment of the FL display flashes
to indicate that the mode is self-diagnostic function mode
with the protection functions disabled.
CAUTION!
Using this product with the protection function disabled
may cause further damage to this unit. Use special care
for this point when using this mode.
2. When the protection function worked to turn
off the power:
The data of protection function which worked at the
moment is displayed. Then “A1-1. DSP MARGIN” menu
is displayed in a few seconds.
Note: At that time if you reactivate the self-diagnostic
function after turning off the power once
by pressing the “MAIN ZONE
PROTECT” will be displayed because that
situation is equal to “1. When the power is
turned off by usual operation:” described above.
However the protection function history is stored
in a back-up IC with a backup. For details, refer
to “P2 PROTECTION HISTORY” menu.
2-1. When there is a history of protection function
due to excess current.
Cause: An excessive current flowed through the power
amplifier.
Supplementary information: As over current of the
power amplifier is detected, check condition of each
power transistor.
Turning on the power without correcting the abnormality
will cause the protection function to work immediately and
the power supply will instantly be shut off.
• Applying the power to this unit without correcting
the abnormality can be dangerous and cause
additional circuit damage. To avoid this, if “I
PROTECT” protection function works 1 time,
the power will not turn on even when the “MAIN
ZONE
power again, start up the self-diagnostic function.
• The output transistors in each amplifier channel
should be checked for damage before applying
power to this unit.
• Amplifier current should be monitored by
measuring DC voltage across the emitter resistors
for each channel.
Cause: DC output of the power amplifier is abnormal.
Supplementary information: The protection function
worked due to a DC voltage appearing at the speaker
terminal. A cause could be a defect in the amplifier.
Turning on the power without correcting the abnormality
will cause the protection function to work in 5 seconds
and the power supply will be shut off.
2-3. When the protection function worked due to
abnormal voltage in the power supply section.

Supplementary information: The protection function
worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality
will cause the protection function to work in 1 seconds
and the power supply will be shut off.
Notes)
• Applying the power to this unit without correcting
the abnormality can be dangerous and cause
additional circuit damage. To avoid this, if “PS”
and “DC” protection function works 3 times
consecutively, the power will not turn on even
when the “MAIN ZONE
to turn on the power again, start up the selfdiagnostic function.
• The output transistors in each amplifier channel
should be checked for damage before applying
power to this unit.
• Amplifier current should be monitored by
measuring DC voltage across the emitter resistors
for each channel.
Cause: The temperature of the heatsink is excessive.
Supplementary information: The protection function
worked due to the temperature limit being exceeded.
Causes could be poor ventilation or a defect related to
the thermal sensor.
Turning on the power without correcting the abnormality
will cause the protection function to work in 1 seconds
and the power supply will be shut off.
● History of protection function
When the protection function has worked, its history
is stored in memory with a backup.
Even if no abnormality is noted while servicing the
unit, an abnormality which has occurred previously
can be defined as long as the backup data has been
stored.
For details, refer to “P2 PROTECTION HISTORY”
menu.
