- 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 ËšC 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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.

SERVICING NOTES
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 emis-
sion, observe from more than 30 cm away from the objective lens.
US/Canadian model:
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.
DISC MAGAZINE GETTING OUT PROCEDURE
ON THE POWER SUPPLY IS OFF
Remove the CASE (LOWER. T) beforehand
1) Press the lever (ML.S) assy in the direction of arrow A.
2) Removal the magazine assy.
Note: Take out the magazine only when the tray is completely within the
magazine. If the disk or tray is sticking out, turn on the power and
eject the magazine.

TEST DISC
This set can playback a CD-R, CD-RW for audio use. When test
this set, use the following test disc.
Test disc for CD-R: TCD-R082LMT (Part No.: J-2502-063-1)
Notes on CD-R discs
You can play CD-Rs (recordable CDs)
designed for audio use on this unit.
Look for this mark to
distinguish CD-Rs for audio use.
This mark denotes that a disc is
not for audio use.
Some CD-Rs (depending on the equipment
used for its recording or the condition of
the disc) may not play on this unit.
You cannot play a CD-R that is not
finalized*.
*A process necessary for a recorded CD-R disc to
be played on the audio CD player.

JIG ON REPAIRING
When repairing this set, connect the jig (cord) for RF output ex-
tract (Part No. J-2502-058-1) and power supply (Part No. J-2502-
058-2) as the figure shown below.
