WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohms shunted
by 0.15μF.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both
polarities.
“CAUTION”
“F501: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE.”
CAUTION
F501: REPLACE WITH SAME TYPE 5A, 125V FUSE.
ATTENTION
F501: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 5A, 125V.
注意：
All of the P.C.B.s installed in this unit 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.

■DISASSEMBLY PROCEDURES /順
(Remove parts in the order as numbered.)
Cautions for disassembly and reassembly :
• Disconnect the power cable from the AC outlet.
• Spread soft cloth or the like and perform the work on it.
• Use full care as you may be injured by the front grille
or other part.
• All screws must be tightened securely to prevent air
leakage. Check the number of screws and their
positions when installing them.
• When installing parts, be careful not to have anything
such as cables caught between other parts.
• Make sure that all the removed driver (tweeter) parts
are reinstalled at specified positions.
■SERVICE PRECAUTIONS / サービス時の注意事項
安全対策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 C523 on the INPUT (1) P.C.B. is 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, perform discharge by
connecting a discharge resistor (5 k-ohms/10 W) between
C523 terminals.
(For the discharge resistor connection points, refer to page
52 “PRINTED CIRCUIT BOARD [INPUT (1) P.C.B.]” and
page 67 “SCHEMATIC DIAGRAM [INPUT 2/2]”)

When checking the P.C.B. :
• The shield unit removed from the unit does not work
because its grounding is loose. Be sure to connect the
ground of the shield unit to the chassis or GND with a
ground lead or the like. (Fig. A)
• Reconnect all cables (connectors) that have been
disconnected.
• When connecting the cable, use care for the polarity.
