Adjustment
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different

Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.
Items

amplifier output and the VREF reference voltage is
compensated inside the

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.

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.
Using the brush in the cleaner cap, apply 1 or 2 drops of
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.
