.OPERATING THE RESET SWITCH
This CD ITUNER and TAPE DECK/ PRE-AMPLIFIER unit is provided with areset switch on the rear panel. The reset switch serves to ini-
tialize the microprocessor in the each units which controls the CD, TUNER, TAPE DECK and etc block. If the unit is to be serviced or
key input is not acknowledged even when the CD/ TUNER, TAPE DECK and etc. operation buttons are pressed, press the RESET
switch and initialize the microprocessor following the step below.
1). Disconnect the AC power cord from the power outlet.
2). Keep the RESET switch depressed for 60 seconds.
(The backed up electrolytic capacitor is discharged by keeping the RESET switch depress.)
3). Reconnect the AC power cord to the power outlet.
4). Press the CD/TUNER, TAPE DECK and etc. operations, and check their operation.
PARTS LIST
PRODUCT SAFETY NOTICE
.-.’.-.:.”: Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~in the parts list
and the schematic diagram designate components in which safety can be of special significance. When replacing acomponent identi-
fied ~, use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are desig-
nated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts
are acceptably insulated from the supply circuit before returning the product to the customer.
CAUTION: Regular type resistors and capacitors are not list. To know those values, refer to the schematic diagram.
N.S.P :Not available as service parts.

.... LASER BEAM SAFETY PRECAUTIONS (CD)
Do not look straight at the laser beam from the pickup and do Structural Safety Interlock
not point the beam at your fingers or any other part of your
body. This model has adisc chuck lever and top lid. This disc chuck
Note: The laser beam must never be allowed to enter the eyes lever and top lid prevent to expose the laser beam for users.
since this may damage the eyes.
Power must never be supplied to apickup with adamaged laser
output part (objective lens, etc.).

\/
CAUTION -USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED IN THE OPERATING INSTRUCTIONS MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
THE COMPACT DISC PIAYER SHOULD NOT BE ADJUSTED OR REP-AIRED BY ANYONE EXCEPT PROPERLY
QUALIFIED PERSONNEL.

., b.
Precautions for handling the pickup and semiconductors
(particularly the lCs)
The pickup and semiconductors (particularly th lCS) may be
\
damaged if they come into contact with asou ~e of high
voltage static electricity. Do not bring them, therefore, into
contact with or into the vicinity of anything which has been
charged with high voltage static.
The pickup consists of alarge number of optical and precision
parts. Do not store or repair it, therefore, in any location
with ahigh temperature, high humidity, high magnetic fields
or high dust concentration. (Since the pickup contains a
powerful magnet, it must not be brought near any
magnetized objects.)
C.DO not apply Srong external pressure to the pickup or subject
it to impact. Actions like these can cause the printed circuit
board to crack or malfunctioning to occur.
d. The pickup is asingle integrated part which has been very
precisely adjusted. Therefore, its adjustment points and set
screws must not be touched.
2. How to prevent static during handling
a. When replacing any of the parts, disconnect the power plug
from the unit being repaired.
b. All measuring instruments, tools and repair equipment must
be grounded. Cover the work bench where the repair work
will be done with agrounded electrically conductive sheet.
c.Ground the metal part of the soldering iron in order to
safeguard against leakage of electricity from the heater.
d. Repair personnel must wear grounding bands around their
wrists to discharge static picked up by their bodies. These
bands are grounded through aresistor (with alM:
resistance).
Note: Under no circumstances must be the grounding bands be
e.
3.
a.
b.
grounded without aresistor (with a1Ml resistance) since
doing so involves the risk of electric shocks.
Since static in the clothes of the repair personnel will not be
discharged by wearing grounding bands, every care must be
taken not to allow the clothes to touch the pickup and
semiconductors (particularly the ICS).
The pickup, which is asingle integrated part, is kept in a
conductive bag. Use this bag to convey the pickup from one
place to another. [n order to avoid damage resulting from
static which may occur when the pickup is removed from the
bag, make sure that it is not placed on top of the bag.
Cleaning the lens surface
Blow off dust on the lens using the kind of air brush which is
used for cameras.
Remove stubborn dirt with acotton swab dipped in isopropyl
alcohol. Do not use any other type of cleaning fluid since it
may mark the plastic lens.
Notes: ●Do not use too much isopropyl alcohol: the excess ma)
seep inside the pickup.
●The lens is held in place by avery feeble supper
spring. Therefore, when cleaning the lens, avo
applying any more force by the cotton swab than
necessary since this may bend the support spring out
shape.

To enter any service mode other than timer debugging, first simultaneously press the OPEN/CLOSE and BAND keys on the CT unit.
This accesses the service mode entry state. Now press one of the buttons on the CT unit to enter aservice mode. As the service
mode entry state is discontinued after 1second elapses, the system will enter aservice mode only if the next key is pressed within
one second.
1. Confirm the clock
.When the CLOCK key is pressed during the service mode entry state, arectangular wave with afrequency of one- fourth that
of the oscillating frequency (1 .048576MHz) is output from the micro processor’s port CLKOUT.
.The clock output is stopped by pressing either the POWER or SET CLEAR key.

.In this mode, the tracking balance adjustment state (tracking is off) is automatically entered after the tray is completely closed.
If the PLAY key is pressed in this state, the ~racking servo is turned on and playing is begun at the present position.
Therefore, the readout on the display at the time playing is begun indicates the initial position of the pickup (i.e. the position
of the limit switch).

.In this mode, when CD function are used, displays like those shown in Table 3(which represent CD operations different than
normally displayed) appear in the LCD track number display.
.In this mode, the calendar numbers shown in Table 4come on when an error occurs in CD operations, at which time the
track number and calendar displays become fixed at their current readouts. To release these fixed displays, press the STOP key
while operations are stopped.

(3) Digital voltmeter (Input impedance 1Mohm or more) (B) AC Voltage Meter
Notes :a. The adjustments can be using the equipment produced by other manufactures provided that the performance of that
equipment corresponds to that of the above listed models.

PARTS LIST
PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol Ain the parts list
and the schematic diagram designate components in which safety can be of special significance. When replacing acomponent identi-
fied ~, use only the replacement parts Clesignateci, or parts with the same ratings of resistance, wattage or voltage that are desig-
nated in the parts’ list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts
are acceptably insulated from the supply circuit before returning the product to the customer.
CAUTION: Regular type resistors and capacitors are not list. To know those values, refer to the schematic diagram.
N.S.P :Not avairable as service parts.
