OPERATION MANUAL
Setting the AC voltage selector
Check the setting of the AC voltage selector located on the rear panel before plug-
ging the unit into an AC socket. If necessary, adjust the selector to correspond to the
AC power voltage used in your area.
Turn the selector with a screwdriver until the appropriate voltage num-
ber appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).
Connecting the AC power lead
After making all connections, connect the AC power lead to the unit
and then into the wall socket. If you plug in the unit first, it will enter
the demonstration mode.
Notes:
Unplug the AC power lead from the AC socket if the unit will not be in use for a pro-
longed 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, con-
nect 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 illustration ).

System Connections (For CD-BK100W)
Setting the FM/AM Span Selector
The International Telecommunication Union (ITU) has established thatmember coun-
tries should maintain either a 100 kHz or a 50 kHz interval between broadcasting fre-
quencies of FM stations and 10 kHz or 9 kHz for AM station. The illustration shows
the 50/9 kHz zones (regions 1 and 3), and the 100/10 kHz zone (region 2).
Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to the
interval (span) of your area.
To change the tuning zone:
Caution:
This operation will erase all data stored in memory including clock, timer settings,
tuner preset, and CD programme.
1 Press the ON/STAND-BY button to enter the stand-by mode.
2 Set the SPAN SELECTOR switch (on the rear panel) as follows.
For 50 kHz FM interval (9 kHz in AM) 50/9
For 100 kHz FM interval (10 kHz in AM) 100/10
3 Whilst pressing down the / button and the EQUALIZER/X-BASS/DEMO button,
press the ON/STAND-BY button until "CLEAR AL" appears.

Note 1: How to open the changer manually. (Fig. 11-1)
1. In this state, turn fully the lock lever in the arrow direction through
the hole on the loading chassis bottom.
2. While holding the lock lever, rotate the cam gear anticlockwise until the
cam gear rib engages with the clamp lever. (Fig. 11-2)
3. After that, push forward the slide chassis.
Note 2:
1. After removing the connector for the optical pickup from the
connector,wraptheconductivealuminiumfoilaroundthefrontend
of the connector so as to protect the optical pickup from electro-
static damage.
Note 3:
1. Be careful not to break the claw of the CD mechanism.
2. When fining back the cam gear assembly, let it lock by front
movement.

•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.
