SAFETY PRECAUTION FOR SERVICE MANUAL
z
This product is classified as a CLASS 1 LASER PRODUCT.
z
WARNINGS:
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than
Class I Requirements. However, the following precautions must be observed during servicing to protect
your eyes against exposure to the Laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup
is on a position outer than the lead-in position, the Laser will light for several seconds to detect a
disc. So not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already
been adjusted prior to shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustment, or performance of procedures other than those specified
herein may result in hazardous radiation exposure.

CD SECTION
Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary tp readjust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.
TEST MODE
Start
While holding down the “Stop” and “RANDOM” button simultaneously, move the FUNCTION switch to “CD”.
Note
1. When the CD DOOR switch is in the OFF position, i.e. CD DOOR is opened, the unit is now in test mode. Press the “UP/
F.FORWARD” and “DOWN/F.REVERSE” buttons to move the pickup back and forth.
2. The LCD display should be the same as it is for normal CD operations.
Operation
Pressing the “UP/F.FORWARD” button will move the pickup outward.
Pressing the “DOWN/F.REVERSE” button will move the pickup inward.
LCD MODE
Start
Display
After connecting the 10kohm resistor between IC201A 13 pin and GND, holding down the “Stop” and “RANDOM” button
simultaneously and move the FUNCTION switch to “CD”.

LASER LIGHTING CONFIRMATION
1. Remove the front cabinet according to the disassembly method.
2. Short the TP of the Figure 13-1 to turn on the CD DOOR switch (SW810).
3. While holding down the "Stop" and "RANDOM" button simultaneously, move the FUNCTION switch to "CD".
4. Open the CD DOOR and press the PLAY button. The laser lights up for a few seconds. (During this time, the pickup lens moves up and down and
adjusts the focus to check if there is a disc or not.)
PREPARATION FOR LASER LIGHT UP
1. Before the laser light up, CD DOOR switch (SW810) terminals have to be short with the solder. Resistor of 330ohm is put from 13 PIN of IC201A,
and you must connect it to GND of PWB. (Refer to PWB of Figure 13-1.)

SETTING METHOD FOR LASER LIGHT UP
1. In power OFF state, set the Function switch to ON, keeping to be pressed the "Stop" and "RANDOM" button at same time.
After CD initialize finish, The CD TEST mode is set, and the LCD indicate to the total tracks of the disc .
Release the PLAY button.
The CD TEST mode is set when the LCD indicate to "1".
Then out the above circuit.
2. In above TEST mode state, press once the PLAY button.
The laser is light up when LCD indicate to "CD".
SETTING FOR MAXIMUM LASER POWER
1. In above laser light up state, adjust the variable resistor (VR1A) on pickup PWB to maximum laser power.
Maximum laser power: Rotate the variable resistor (VR1A) to clockwise.

Resistor:
(
To differentiate the units of resistors, such symbol as K and M are
used: the symbol K means 1000 ohm and the symbol M means
1000 kohm and the resistor without any symbol is ohm-type
resistor. Besides, the one with “Fusible” is a fuse type.

To indicate the unit of capacitor, a symbol P is used: this symbol P
means pico-farad and the unit of the capacitor without such a
symbol is microfarad. As to electrolytic capacitor, the expression
“capacitance/withstand voltage” is used.

TROUBLESHOOTING (CD SECTION)
When the CD does not function
The CD section may not operate when the objective lens of the optical pickup is dirty. Clean the objective lens, and check the playback operation.
When this section does not operate even after the above step is taken, check the following items.
Remove the cabinet and follow the trouble shooting instructions.
“Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens. Before attempting
any adjustment make certain that the lens is clean. If not, clean it as mentioned below.”
Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.
HOW TO USE
1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the
brush on the CD cleaner disc which has the mark ▲ next to it.
Cleaning fluid
2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then
press the play button.
3. You will hear music for about 20 seconds and the CD player will automatically stop.
If it continuous to turn, press the stop button.
CAUTION
The CD lens cleaner should be effective for 30-50 operations, however if the brushes
become worn out earlier then please the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft
cloth.
Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the
event of this happening then drink and / or rinse with clean water and seek medical
advice.
The CD cleaner disc must not be used on car CD players or on computer CD-ROM
drives.
All rights reserved. Unauthorized duplicating, broadcasting and renting this product
is prohibited by law.
