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 1 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) TheLaserPowerOutputofthePickupinsidetheunitandreplacementservicepartshavealreadybeenadjustedpriortoshipping.
(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.
VOLTAGE SELECTION
Before operating the unit on mains, check the preset voltage. If the voltage is different from your local voltage, adjust the voltage
as follows, turn the selector with a screwdriver until the appropriate voltage number appears in the window (110V, 127V, 220V
or 230V - 240V AC).

OPERATION MANUAL
PREPARATION FOR USE
Connecting the AC power lead
Check the setting of the AC voltage selector located on the
rear panel before plugging the unit into an AC socket. If nec-
essary, adjust the selector to correspond to the AC power
voltage used in your area.
Selector adjustment:
Turn the selector with a screwdriver until the appropriate
voltage number appears in the window (110 V, 127 V, 220 V
or 230 V - 240 V AC).
Notes:
Plug the AC power lead into an AC socket, after any con-
nections.
Unplug the AC power lead from the AC socket if the unit
will not be in use for a prolonged period of time.
Never use a power lead other than the one supplied. Use
of a power lead other than the one supplied may cause
an electric shock or fire.
AC Plug Adaptor
In areas (or countries) where an AC socket as shown in
illustration is used, connect the unit using the AC plug
adaptor supplied with the unit, as illustrated. The AC plug
adaptor is not included in areas where the AC wall socket
and AC power plug can be directly connected (see illustra-
tion ).
Note for users in Australia and New Zealand:
An AC plug adaptor is not supplied if the lead has an Austra-
lian Standard plu
g
.
AM/FM interval (span)
The International Telecommunication Union (ITU) has
established that member countries should maintain either a
10 kHz or a 9 kHz interval between broadcasting frequen-
cies of any AM station. The illustration shows the 9 kHz
interval zones (regions 1 and 3), and the 10 kHz interval
zone (region 2).
Before using the unit, set the SPAN SELECTOR switch (on
the rear panel) to AM tuning interval (span) of your area.
To change the tuning zone:
1
Press the ON/STAND-BY button to enter the stand-
by mode.
2
Set the SPAN SELECTOR switch to "50/9" for 9 kHz
AM interval (50 kHz FM interval), and "100/10" for 10
kHz AM interval (100 kHz FM interval).
3
Whilst pressing down the / button and the
EQUALIZER/X-BASS/DEMO button, hold down the
ON/STAND-BY button for at least 1 second.
"CLEAR AL" will appear.
Caution:
The operation explained above will erase all data stored
in memory including clock and timer settings, and tuner
and CD presets.

PREPARATION FOR USE
Remote control
When inserting or removing the batteries, push them towards the battery terminals. Installing the batteries incorrectly may cause the unit to malfunction.
Precautions for battery use:
Insert the batteries according to the direction indicated in the battery compartment. Replace all old batteries with new ones at the same time. Do not mix old and new batteries. Remove the batteries if they are weak or if the unit will not be used for long periods of time. This will prevent potential damage due to battery leakage.
Caution: Do not use rechargeable batteries (nickel-cadmium battery, etc.). Notes concerning use:
Replace the batteries if the operating distance is reduced or if the operation becomes erratic. Periodically clean the transmitter LED on the remote con- trol and the sensor on the main unit with a soft cloth. Exposing the sensor on the main unit to strong light may interfere with operation. Change the lighting or the direc- tion of the unit. Keep the remote control away from moisture, excessive heat, shock, and vibrations.

Error State Code
[Servo System Error]

[Error during close operation]
0101 Open/Close SW Low → High not functioning
0103 Open/Close SW High →Low not functioning
[Error during open operation]
0201 Open/Close SW Low → High not functioning

[Error during skip operation]
0302 Pickup-in SW is not detected
0306 During Disc 1 search, Open/Close SW or Clamp SW
or Disc SW do not change to low.
0307 Clamp SW Low → High not functioning
0308 Clamp SW High →Low not functioning
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWB and pickup
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.
13-2 EFBL)
(3)Gainadjustment(Thegainis compensatedinside theIC
sothatthe loop gain at the gain crossover frequency will
be 0 dB.)
* Focus gain adjustment
* Tracking gain adjustment

•The indicated voltage in each section is the one measured
by Digital Multi meter 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 “ ” ( ) 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 micro-micro-farad and the unit of the
capacitor without such a symbol is micro farad. As to
electrolyticcapacitor,theexpression“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.
