SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED
LINE WITH MARK 0ON 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 PUB-
LISHED BY SONY.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 °C dur-
ing 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 CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
TheAC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’instructions to use these
instruments.
2. A battery-operatedAC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2VAC range are suit-
able. (See Fig. A)

About CD-Rs/CD-RWs
This CD player can play CD-Rs/CD-RWs
recorded in the ATRAC3plus/ATRAC3,
MP3 or CDDA* format, but playback
capability may vary depending on the quality
of the disc and the condition of the recording
device.
*CDDA is the abbreviation for Compact Disc
Digital Audio. It is a recording standard used for
the Audio CDs.
Note
Use only the supplied AC power adaptor. Do not
use any other A C power adaptor.

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40 °C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges oc-
cur such as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

ZS-XN30 SECTION 1
SERVICING NOTES
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S801. (push switch type)
The following checking method for the laser diode is operable.
•Method
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig.1.
Note: Do not push the detection lever strongly, or it may be bent or dam-
aged.
3. Press the ubutton.
4. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up.
In this operation, the object lens will move up and down 2
times along with inward motion for the focus search.

About ESP (Electronic Shock Protection)
function
When a CD is playing, the ESP function is always
activated. The ESP function prevents the sound from
skipping by using a buffer memory that stores music data
for about 10 seconds.
The structure of ATRAC CDs/MP3 CDs
ATRAC CDs/MP3 CDs consist of files and groups. A
file is equivalent to a track of an audio CD. A group
is a bundle of files and is equivalent to an album.
For MP3 CDs, this CD player recognizes an MP3 folder as
a group so that ATRAC CDs and MP3 CDs can be
operated in the same way.
Notes
¥ If ATRAC3plus/ATRAC3
files and MP3 files are
recorded on the same CD,
this CD player plays the
ATRAC3plus/ATRAC3
only.
¥The playback capability of
this CD player may vary
depending on the quality of
the disc and the condition of
the recording device.
¥Acceptable characters on
this CD player are as
follows:
—Ato Z
—ato z
—0to 9
—!" # $ % & ’ ( ) * + , - . / :
; < = > ? @ [ \ ] ^ _ ‘ { | }
~
If you use other characters
on you computer by using
an software such as
SonicStage, they are
displayed as — on this CD
player.
¥On a disc that has
ATRAC3plus/ATRAC3/
MP3 files, do not save files
in other formats and do not
make unneccessary groups.
ATRAC CD
Playing order of ATRAC CDs and MP3 CDs
For ATRAC CDs, files are played in the order selected in
SonicStage.
For MP3 CDs, the playing order may differ depending on
the method used to record MP3 files on the disc. In the
following example, files are played in order of 1to 7.
Notes on ATRAC CDs
¥Maximum number of groups: 255
Maximum number of files: 999
¥CD-Rs/CD-RWs recorded in the ATRAC3plus/ATRAC3 format
cannot be played on your computer.
Notes on MP3 CDs
¥Maximum number of groups: 100
Maximum number of files: 400
Maximum directory level: 8
¥Agroup that does not include an MP3 file is skipped.
¥Be sure to add the file extension mp3 to the file name.
However, if you add the file extension mp3 to a file other than
an MP3 file, the player will not be able to recognize the file
properly.
¥ This player can play bit rates of 16 to 320 kbps, and sampling
frequencies of 32/44.1/ 48 kHz. Variable Bit Rate (VBR) file
can also be played.
¥ To compress a source in an MP3 file, we recommend setting the
compression parameters to 44.1 kHz, 128 kbps, and
Constant Bit Rate.
¥ To record up to the maximum capacity, set the writing software
to halting of writing.
¥To record to the maximum capacity at one time up on media that
has nothing recorded on it, set the writing software to Disc at
Once.
