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.
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.

Music sources playable on this CD player
You can play the following 3 music sources on this CD player:
· Audio CDs
·ATRAC3plus/ATRAC3 format files
· MP3 files
Usable disc formats
You can use ISO 9660 Level 1/2, Joliet extension format discs only.
ATRAC3plus and ATRAC3
"ATRAC3plus," which stands for "Adaptive Transform Acoustic
Coding3plus" is audio compression technology, developed from the
ATRAC3 format. Though the ATRAC3plus format can compress
music content to about 1/20 of its original size, you can still enjoy
high quality sound. The available transfer bit rates are 64 kbps and
48 kbps.
"ATRAC3," which stands for "Adaptive Transform Acoustic
Coding3" is audio compression technology that satisfies the demand
for high sound quality and high compression rates. The ATRAC3
format can compress music content to about 1/10 of their original
size, which contributes to reduction of the media volume. The
available transfer bit rates are 132 kbps, 105 kbps and 66 kbps.
The usable number of groups and files
· Maximum number of groups: 255
· Maximum number of files: 999
For details, refer to the supplied booklet "SonicStage Simple Burner."
MP3 files
MP3, which stands for MPEG-1 Audio Layer3, a standard for audio
files compression supported by the Motion Picture Experts Group,
an ISO (International Organization for Standardization) working
group, enables compression of audio files to about 1/10 of the data
size of a standard compact disc. Since the MP3 encoding algorithm
is public, there are various encoders/decoders that are compliant
with this standard, including freeware that is available for no charge.
Thus, the MP3 standard is widely used in the computer field.

SERVICE NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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.
Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface
of the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.
Before Replacing the Optical Pick-Up Block
Please be sure to check throughly the parameters as par the "Opti-
cal Pick-Up Block Checking Procedures" (Part No.: 9-960-027-
11) issued separately before replacing the optical pick-up block.
Note and specifications required to check are given below.
· FOK output : IC601 yg pin (or TP618 (FOK))
When checking FOK, remove the lead wire to disc motor.
· RF signal P-to-P value : 0.45 ± 0.1 Vp-p
· The repairing grating holder is impossible.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S820. (push switch type)
The following two checking methods for the laser diode are
operable.
· Method:
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. With a disc not set, turn on the S820 with a screwdriver having a
thin tip as shown in Fig.1.
or TAP805 is shorted as shown in Fig.2.
Note: Do not push the detection lever strongly, or it may be bent
or damaged.
3. Press the N X button.
4. Observing the objective lens, check that the laser diode emits
light.
When the laser diode does not emit light, automatic power
control circuit or optical pick-up is faulty.
In this operation, the objective lens will move up and down 5
times along with inward motion for the focus search.
