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.

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 (110V, 127V, 220V or 230V - 240V 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.
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 ).
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 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.

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.
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)Trackingbalanceadjustment(waveformdrawingFig.13-

•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 “ ” ( ) 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 microfarad. 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.
