DVD/CD SECTION
• Adjustment
Since this DVD/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.

BEFORE TRANSPORTING THE UNIT
The following process need to be taken after set tapering/
parts replacement.
1. Press the ON/STAND–BY button to enter stand–by
mode.
2. While pressing down the 3 button and the X–BASS/
DEMO button, press the ON/STAND–BY button until
“CLEAR AL” appears.
3. While pressing down the 4˜1 button and the
X–BASS/DEMO button, press the ON/STAND–BY button
until “WAIT” ––> “FINISHED” appears.
4. Unplug the AC cord and the unit is ready for
transporting.
Notes for handling the mechanism unit
Since the pickup semiconductor laser can easily damaged
by the static electricity, handle the mechanism unit with care.
To prevent damage by the static electricity during
transportation, the LD terminals are short-circuited at 2
points on the PWB. Unsolder them by a soldering iron after
completing the connection. When you return the mechanism
unit, solder the terminals again.

* 'CHECKING'
If Error is detected, 'CHECKING' will be displayed instead
of 'ER–CD**' display will only be displayed when error had
been detected for the 5th times.
Speaker abnormal detection and +B PROTECTION display
In case speaker abnormal detection or +B PROTECTION
had occured, it can be checked by pressing 'POWER',
'VIDEO' and 'X-BASS' key twice. Display will show “S**B**”.
S is referring to speaker abnormal detection and B is
referring to +B PROTECTION. ** is in hex value.

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 “ ” ( ) 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.
