SERVICE NOTES
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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
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 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.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
This caution
label is located
inside the unit.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS 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

unpacked the player) onto the disc tray, and use
adhesive tape to secure the bar. If you fail to
attach the protective bar, the player may be
damaged during transport.

Other Functions
i.LINK connections
The use of i.LINK cables to connect i.LINK components
as shown below is called a “daisy chain” configuration.
Data can be transmitted between any two
components even if they are indirectly connected.
Branch connections
• Any i.LINK component with three or more i.LINK
connectors can serve as a branch point.
• Up to 63 i.LINK components can be connected in a
single configuration. However, the maximum
number of components that can be daisy-chained in
a single route is 17 (i.e., a maximum of 16 i.LINK
connecting cables in a row). Each i.LINK cable used
in a single route is called a “hop.” For example,
there are 6 hops in the route between A and C in the
illustration below, and 3 hops in the route between A
and D.
BA
DC
Each route between A and B; A and C; A and D; B and
C; B and D; and C and D in the illustration above can
have 16 hops (i.e., 17 components).
Loop-connetion
A signal output from one component is transmitted to
all other components. A loop connection should thus
be avoided to prevent the return of a signal to its
source.
Notes
• Some i.LINK components (such as personal computers) do
not transfer signals when they are turned off. Refer to the
operation manual of each component to be connected
before you hook them up.
• The maximum transmission rate of an i.LINK component is
printed near its i.LINK connector. The indications S100,
S200, and S400 refer to maximum transmission rates of 100,
200, or 400 Mbps*, respectively. The actual transmission
rate may be faster or slower, depending on the differences
in transmission rates and specifications among the
connected components.
z
What is Mbps?
“Mbps” is an abbreviation for megabits per second. It
indicates the amount of data transmitted per second. For
example, a rate of 200 Mbps means 200 megabits of data
are transmitted in one second.

between the receiving component (of the audio signal)
and the sending component. Establishing a “LINC”
means establishing a logical path for the transmission
of digital audio signals between the two components.
Each logical path has an ID number. Since the
component that sends an audio signal must output the
signal to a path, and the component that receives the
signal must input it from the same path, the path must
be mutually known by both components. During the
establishment of a LINC, the following communication
