This appliance is classified
as a CLASS 1 LASER
product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
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 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.

SERVICING NOTE
CDP-XE570
HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH
TURNS OFF
Insert a tapering driver into the aperture of the unit bottom, and turn
in the direction of arrow.
Use a flat (–) head screwdriver to open the CD tray b y manual operation. (Flat head screwdriver with nominal blade length of 3mm.)
*
To close the disc table, turn the driver in the reverse direction.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostatic 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 from more than 30 cm away from the objective lens.
Pull out disc table.

CD-TEXT TEST DISC
This unit is able to display the TEXT data (character information)
written in the CD on its fluorescent indicator tube.
The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is used
for checking the display.
To check, perform the following procedure.
Procedure:
1. Turn ON the power and set the test disc.
2. Press the H button and play back the disc.
3. The following will be displayed on the fluorescent indicator
tube.
Display : 1kHz/0 dB/– – – –
4. Rotate the l AMS L knob to switch the track. The
text data of each track will be displayed.
Restrictions in CD-TEXT Display
In this unit, some special characters will not be displayed properly . These will be displayed as a space or a character resembling it. For details,
refer to “Table 2 : CD-TEXT DISC Recorded Contents and Display”.
