SAFETY PRECAUTION FOR
SERVICE MANUAL
Precaution to be taken when replacing and servicing the
Laser Pickup.
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. Do 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 adjustments, or performance
of procedures other than those specified herein may result
in hazardous radiation exposure.

How to remove the loading motor
(See Fig. 13-1)
1. Bend the hooks (A1) x 5 pcs., to remove the loading motor.
How to remove the pickup (See Fig. 13-2)
1. Remove the screws (B1) x 2 pcs., to remove the shaft (B2).

Notes:
1: Description of the "FM IF Adjustment" is not carried on this
Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a
complete unit, so you can't obtain each part individually

• Adjustment
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWBs and pickups
can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.
Items adjusted automatically
(1) Offset adjustment (The offset voltage between the head
amplifier output and the VREF reference voltage is
compensated inside the IC.)
* Focus offset adjustment
* Tracking offset adjustment
(2) Tracking balance adjustment (waveform drawing Fig.
14-2 EFBL)
(3) Gain adjustment (The gain is compensated inside the IC
so that the loop gain at the gain crossover frequency will
be 0dB.)
* Focus gain adjustment
* Tracking gain adjustment

NOTES ON SCHEMATIC DIAGRAM
• 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.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.
CD-BA1200H
• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chassis with no signal given.
1. In the tuner section,
( ) indicates AM
< > indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.
( ) indicates the record state.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
• Parts marked with “ ” ( ) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.

TROUBLE SHOOTING
When the CD does not function
When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. 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.
Parts code
1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ
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.
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.
Cleaner Fluid
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 disk must not be used on car CD players or on computer CD ROM
drives.

Cleaner disc
When a CD cannot be played
1. "E-CD01" is displayed.
(1) Check the power to IC2 (LC78641E), the presence of the clock signal (16.93 MHz) and the status of the RESET terminal
(pin 71 on IC2).
(2) Did the pickup move to the PICKUP-IN Switch (SW4) position?
If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).
2. Pressing the CD operation key is accepted, butplayback does not occur.

Explanation of capacitors/resistors parts codes
Capacitors
VCC ....................... Ceramic type
VCK........................ Ceramic type
VCT........................ Semiconductor type
VC • • MF ............... Cylindrical type (without lead wire)
VC • • MN............... Cylindrical type (without lead wire)
VC • • TV................ Square type (without lead wire)
VC • • TQ ............... Square type (without lead wire)
VC • • CY ............... Square type (without lead wire)
VC • • CZ ............... Square type (without lead wire)
VC • • • • • • • • • J .. The 13th character represents capacity difference.
("J" ±5%, "K" ±10%, "M" ±20%, "N" ±30%,
"C" ±0.25 pF, "D" ±0.5 pF, "Z" +80-20%.)
If there are no indications for the electrolytic capacitors, error is ±20%.
NOTE:
Parts marked with “ ” are important for maintaining the safety of the set.
Be sure to replace parts with specified ones for maintaining the safety and performance of the set.
Resistors
VRD ....................... Carbon-film type
VRS........................ Carbon-film type
VRN ....................... Metal-film type
VR • • MF ............... Cylindrical type (without lead wire)

VR • • TQ ............... Square type (without lead wire)
VR • • CY ............... Square type (without lead wire)
VR • • CZ ............... Square type (without lead wire)
VR • • • • • • • • • J .. The 13th character represents error.
("J" ±5%, "F" ±1%, "D" ±0.5%.)
If there are no indications for other parts, the resistors are ±5%
carbon-film type.
