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 CHECK-OUT
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 passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
Fig. A)

SECTION 1
SERVICING 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.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree 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
occur 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.

Notes on playing MP3 discs
• Do not save other types of files or unnecessary folders on a disc that
has MP3 files.
• Folders that have no MP3 files are skipped.
• MP3 files are played back in the order that they are recorded onto
the disc.
• The system can only play MP3 files that have a file extension of
“.MP3.”
• If there are files on the disc that have the “.MP3” file extension,
but that are not MP3 files, the unit may produce noise or may
malfunction.
• The maximum number of:
− folders is 150 (including the root folder).
− MP3 files is 255.
−
MP3 files and folders that can be contained on a single disc is 300.
− folder levels (the tree structure of files) is 8.
• Compatibility with all MP3 encoding/writing software, recording
device, and recording media cannot be guaranteed. Incompatible
MP3 discs may produce noise or interrupted audio or may not play
at all.
Notes on playing multisession discs
• If the disc begins with a CD-DA (or MP3) session, it is recognized
as a CD-DA (or MP3) disc, and playback continues until another
session is encountered.
• A disc with a mixed CD format is recognized as a CD-DA (audio)
disc.

Number of repeat for CD playback is 5 times when the repeat mode
is “REPEAT”. This mode is used to enables CD to repeat playback
for limitless times.
Procedure:
1. Press the I/1 button to turn the power on.
2. Press the [CD] button to select “CD”.
3. Press three buttons of s , [CD] and 7 simultaneously.
4. The message “LIMIT OFF” is displayed on the fluorescent
indicator tube momentarily, CD repeat 5 limit is cancelled.
CD POWER MANAGE
This mode is used to changed over CD power on/of f for decreasing
of reception noise in the tuner mode.
Procedure:
1. Press the I/1 button to turn the power on.
2. Press the [CD] button to select “CD”.
3. Press the I/1 button to turn the power off.
4. Press two buttons of s and I/1 simultaneously.
5. The message “CD POWER ON” or “CD POWER OFF” is
displayed on the fluorescent indicator tube, and CD power
on/off changed over in the tuner mode.
