ADJUSTMENT POINTS
CD SECTION
l
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 0
dB.)

NOTES ON SCHEMATIC DIAGRAM
l
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 pica-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

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.

are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and

TROUBLESHOOTING
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 off the power, and wipe the lens softly using a cleaning paper moistened with commercially available cleaning solution so
as not to damage it. Be careful not to touch the lens with bare hands.
Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use a
cleaning disc designed for CD optical pickup lenses..
Parts code
1. 1 CD optical pickup Lens cleaner disc
1 UDSKA0004AFZZ
1.
Using the brush in the cleaner cap, apply 1 or 2 drops of
th:e
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.
Cleaning fluid
\
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.
l
The CD lens cleaner should be effective for
30-50
operations, however if the
brushes become worn out earlier then please the cleaner disc.
0
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft
cloth.
0
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.
0
The CD cleaner disc must not be used on car CD players or on computer CD-ROM
drives.

(2) Does 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, but playback does not occur.
