IMPORT ANT SER VICE 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
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.

2. Inspect all protective devices such as insulating materials,

cabinet, terminal board, adjustment and compartment covers
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

having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

Do not open the compartment forcibly.
Wait until electricity resumes.

Remote control

Symptom Possible cause

The remote control does not oper­ate.

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?

Condensation

Sudden temperature changes, storage or opera­tion in an extremely humid environment may
cause condensation inside the cabinet (CD pick­up, 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 condensa­tion on the transmitter with a soft cloth before op­erating the unit.

Troubleshooting chart

If trouble occurs

When this product is subjected to strong external interference (mechanical shock,
excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is
operated incorrectly, it may malfunction.

If such a problem occurs, do the following:

1 Set the unit to the stand-by mode and turn the power on again.
2 If the unit is not restored in the previous operation, unplug and plug in the unit,

and then turn the power on.

Note:

If neither operation above restores the unit, clear all the memory by resetting it.

Clearing all the memory (reset)

1 Press the ON/STAND-BY button to enter the power stand-by mode.
2 While pressing down the CLOCK button and the EQUALIZER/X-BASS/DEMO

button, press the ON/STAND-BY button until "CLEAR AL" appears.

Caution:

This operation will erase all data stored in memory including clock, timer settings,
tuner preset, and CD program.

Before transporting the unit

On the back of this unit is equipped with a transport screw in order to prevent damage
during transportation.

1 Press the ON/STAND-BY button to turn the

power on.

2 Press the CD button.
3 Press the OPEN/CLOSE button to open

the disc tray.

Remove all CDs inserted in the unit.

4 Press the OPEN/CLOSE button to close

the disc tray.

Make sure that "NO DISC" is displayed.

5 Press the ON/STAND-BY button to enter the

stand-by mode, and then unplug the AC
power cord from the AC outlet.

CD SECTION

• 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.15-2 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.)

* Focus gain adjustment
* Tracking gain adjustment

* 'CHECKING'
If Error is detected, 'CHECKING' will be display instead of 'ER­CD**' display. 'ER-CD**' display will only be display when
error had been detected for the 5 th times.

When Pickup set inner position, inner switch
cannot detect 'ON' level for 10 secs.

When tray moves to Open/Close, Open/Close switch
cannot detect 'ON' level for 7 secs.
When disc table rotate to target position.
Clamp switch cannot detect 'ON' level for 7 secs.

When disc table set to Disc1 position for 1 st time,
cannot detect 'ON' level for 14 secs.

When it changes to CD function, DSP cannot read
initial data.

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.

• 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 “ 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.
