SECTION 1
SERVICE NOTES
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
The following caution label is located inside the unit.
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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
CHUCK PLA TE 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
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Press CD open knob.
2. Open the lid for CD.
3. Push on SWITCH as following figure.
4. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Po wer Control circuit or
Optical Pick-up is broken.
Objective lens moves up and down once for the focus search.

SECTION 2
GENERAL
This section is extracted
from instruction manual.
1.Perform the traverse check in the CD test mode.
After check, be sure to exit the test mode.
2.Perform check in the order given.
3.Use the disc (YEDS-18, Parts No. 3-702-101-01) only when
so indicated.
Before Check
Put the set into test mode and perform the following checks.
Repair if there are any problems.
• Sled Motor Check
Press + , = keys and confirm that the Optical pick-up moves
smoothly from the innermost to outermost circumference and back
smoothly and with no catching or abnormal noises.
(Cancellation of BTL mute)
+ : Optical pick-up moves to the outer circumference.
= : Optical pick-up moves to the inner circumference.
E-F Balance Check
Adjustment Location : MAIN board (See page 23)
This check is to be done when the optical pick-up block is replaced.
Check Procedure:
1.Connect the oscilloscope to test point TP (VC) and TP (TE) on
MAIN board.
2.Put the set into test mode.
3.Optical pick-up setting to the center by + or = button
pushing.
4.Insert disk (YEDS-18) and press ^ button.
5.Check that the oscilloscope traverse wav eform is symmetrical,
as shown in the figure below.
6.Release test mode after adjustment is completed.

•Focus Search Check
1.Press the CD ^ key. (Focus search operation is performed
continuously.)
2.Look at the Optical pick-up objective lens and confirm that it
moves up and down smoothly, with no catching or abnormal
noises.
3.Press p button.
Confirm that focus search operation stops. If it does not, press
p button again longer.
How to Enter the Set into T est Mode
1.Turn the AC CORD IN (Adaptor).
(LCD 501 indicator blinks the test mode pattern.)
2.Short-circuit between the lands as shown on the control (1)
board.
How to Exit the T est Mode
Turn the POWER OFF.

Adjustment Location : MAIN board (Component side)
(See page 23)
This check is to be done when the optical block replaced.
Check Procedure:
1. Connect the oscilloscope to test point TP (VC) and TP (RF) on
MAIN board.
2. Put the set into test mode.
3. Opitical pick-up setting to the center by + or – button pushing.
4. Insert disk (YEDS-18) and press ^ button.
5. Press the MODE button. (Tracking servo ON)
6. Check that the oscilloscope wa vewform is as sho wn in the figure
below (eye pattern).
A good eye pattern means that the diamond shape (◊) in the
center of the waveform can be clearly distinguished.
7. Release test mode after adjustment is completed.

Focus/Tracking Gain Check
Adjustment Location : MAIN board (Component side)
(See page 23)
A frequency response analyzer is necessary in order to perform this
check exactly.
However , this gain has a mar gin, so e ven if it is slightly off, there is
no problem.
Focus/Tracking gain determines the pick-up follo w-up (vertical and
horizontal) relative to mechanical noise and mechanical shock when
the 2-axis device operate.
