 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.
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 more than 30 cm away from the  objective
lens.
 CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.
• Code number of Chuck Plate Jig : X-4918-255-1

SERVICING NOTES
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Press CD open knob.
2. Open the lid for CD.
3. Push on SWITCH (S701) as following figure.
4. Confirm the laser diode emission while observing the
objecting lens. When there is no emission, Auto Power
Control circuit or Optical Pick-up is broken.
Objective lens moves up and down once for the focus
search.

SAFETY  CHECK-OUT (US model)
After correcting the original service problem, perform the
following 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
The AC 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-operated AC 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” indication is 0.75
V, so analog meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)

SOFTWARE AND  WRITING
SOFTWARE
¥ To compress  a source  for an MP3 file, we
recommend setting the transfer bit 
rate of
the compression  software  to 
44.1 kHz ,
128kbps , and  Constant Bit Rate .
¥ To record up to the maximum capacity, set
to the  halting  of writing .
¥ To record  at one time up to the maximum
capacity on media that has nothing
recorded it, set to  Disc at Once .
NOTES FOR SAVING FILES ON
THE MEDIA
When the disc is inserted,  the player reads
all the  files on  that  disc.   If there  are  many
folders or non-MP3 files on the disc, it may
take a long time for play to begin or for the
next MP3 file to start play.
Do not save  unnecessary  folders  or files
other than MP3 ones  in the disc to be used
for MP3  listening.
We recommend that you do not save other
types files or unnecessary  folders on a disc
that has  MP3 files.
About “MP3”
What is the MP3?
MP3 (MPEG 1 Audio Layer-3)  is a standard
technology and format for compressing  a
sound sequence.  The file is compressed  to
about 1/10 of its original size. Sounds
outside the range of human hearing are
compressed while the sounds we can hear
are not compressed.
Playable “MP3” files on this
player
You can only play MP3 files recorded  by
following requirements.
USABLE MEDIA
CD-Rs and CD-RWs
USABLE DISC FORMAT
You can use  ISO 9660 Level 1 format discs,
not including the  expanded  format.  In
some cases,  MP3 files that are recorded  in a
format other than ISO 9660 Level 1 may not
play normally or the file and folder names
may not be displayed  correctly.
The major specifications  of the ISO 9660
Level 1 format are as follows:
¥ Maximum directory steps:   8
¥ Usable characters  for a file/folder name:
A - Z, 0  - 9,  _  (underscore)
¥ Maximum  number  of characters  for a  file
name: 12 including quotation marks and a
3-character extension code
