IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinchedorthathardwareisnotlodgedbetweenthechassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet,terminalboard,adjustmentandcompartmentcovers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5 kohm, 10 watt resistor
paralleled by a 0.15 µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
havingareturnpathtothechassis(antenna,metalcabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.
AllcheckmustberepeatedwiththeAClinecordplugconnection
reversed.
Anyreadingof0.3voltRMS(thiscorrespondsto0.2milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio

Condensation
Symptom Possible cause
The clock is not on time. Did a power failure occur? Reset the
clock.
When a button is pressed, the unit
does not respond. Set this unit to the power stand-by mode and then turn it back on.
Ifthe unitstill malfunctions,reset it.
No sound is heard. Is the volume level set to "0"?
Are the headphones connected?
Are the speaker wires disconnected?
Symptom Possible cause
Playback does not start. Is the disc loaded upside down?
Playback stops in the middle or is
not performed properly. Does the disc satisfy the standards?
Is the disc distorted or scratched?
Playback sounds are skipped, or
stopped in the middle of a track. Is the unit located near excessive vibra- tions?
Is the disc very dirty?
Has condensation formed inside the unit?
Symptom Possible cause
Radio makes unusual noise con-
secutively. Is the unit placed near the TV or comput- er?
Is the FM/AM loop antenna placed proper-
ly? Move the AC power cord away from
the antenna if located near.
Symptom Possible cause
Cannot record. Is the erase-prevention tab removed?
Cannot record tracks with proper
sound quality. Is it a normal tape? (You cannot record on a metal or CrO tape.)
Cannot erase completely.
Sound skipping. Is there any slack?
Is the tape stretched?
Cannot hear treble. Are the capstans, pinch rollers, or heads
dirty?
Sound fluctuation.
Cannot remove the tape. If a power failure occurs during playback,
the heads remain engaged with the tape.
Do not open the compartment forcibly.
Wait until electricity resumes.
Symptom Possible cause
The remote control does not oper-
ate. Is the AC power cord of the unit plugged in?
Is the battery polarity respected?
Are the batteries dead?
Is the distance or angle incorrect?
Does the remote control sensor receive
strong light?
Sudden temperature changes, storage or opera-
tion in an extremely humid environment may
cause condensation inside the cabinet (CD pick-
up, tape heads, etc.) or on the transmitter on the
remote control.
Condensation can cause the unit to malfunction.
If this happens, leave the power on with no disc
(or cassette) in the unit until normal playback is
possible (about 1 hour). Wipe off any condensa-
tion on the transmitter with a soft cloth before op-
erating the unit.

•Adjustment
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacingthepickup.Therefore,differentPWBsandpickups
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.

•The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas-
sis 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 “ 1” ( ) 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.
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 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.
(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.
