This appliance is classified as a CLASS 1
LASER product.
The CLASS 1 LASER PRODUCT
MARKING is located on the rear exterior.
The following caution label is located
inside the unit.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED
LINE WITH MARK 0 ON THE SCHEMATIC DIA GRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SERVICING NOTES (1)
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objecti ve lens.

Compatible Disc Types
You can play the following discs with this player.
Depending on the type of disc to be played, select the
appropriate indicator by pressing SACD/CD on the front
panel of the player or on the remote (pages 11).
Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
Press SACD/CD repeatedly so that “SUPER AUDIO CD”
appears in the display (the SACD/CD LED turns on).
*High density signal layer for the Super Audio CD
HD (high density) layer
Super Audio CD (dual layer disc)
This disc consists of dual HD layers and is capable of
extended play over long periods.
Press SACD/CD repeatedly so that “SUPER AUDIO CD”
appears in the display (the SACD/CD LED turns on).
Also, as the dual layer disc consists of dual HD layers on
one side only, it is not necessary to turn the disc over.
Super Audio CD + CD (Hybrid disc)
This disc consists of an HD layer and a CD layer. Press
SACD/CD to select the layer you want to listen to. Also,
as the dual layers are on one side, it is not necessary to
