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.

CAUTION

This Mini Component System is classified as a CLASS
1 LASER product.

The CLASS 1 LASER PRODUCT label is located on the
rear cover.

Use of controls, adjustments or performance of proce­dures other than those specified herein may result in haz­ardous radiation exposure.

As the laser beam used in this compact disc player is
harmful to the eyes, do not attempt to disassemble the
cabinet. Refer servicing to qualified personnel only.

VOLTAGE SELECTION

The voltage selector is located on the AC voltage selector box. If adjustment is necessary, ensure to remove plug of AC cord from
AC socket and use a screwdriver to turn the selector in either direction. The correct voltage figure is displayed in the window below
to the adjustment screw.

Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary
to readjust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.

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.

TROUBLESHOOTING (CD SECTION)

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 troubleshooting 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.

Explanation of capacitors/resistors parts codes

Capacitors

VCC ....................... Ceramic type

VCK........................ Ceramic ty pe

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%.

Resistors

VRD ....................... Carbon-film type

VRS........................ Carbon-film type

VRN ....................... Metal-film type

VR • • MF ............... Cylindrical type (without lead wire)

VR • • MN............... Cylindrical type (without lead wire)

VR • • TV................ Square type (without lead wire)

VR • • TQ ............... Square type (without lead wir e)

VR • • CY ............... Square type (without lead wir e)

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.

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.
