LASER BEAM SAFETY PRECAUTIONS (CD)
Do not look straight at the laser beam from the pickup and do
not point the beam at your fingers or any other part of your
body.
Note: The laser beam must never be allowed to enter the eyes
since this may damage the eyes.
Power must never be supplied to a pickup with a damaged laser
output part (objective lens, etc.).

1. Precautions for handling the pickup and semiconductors
(particularly the ICs)
a. The pickup and semiconductors (particularly the ICs) may be
damaged if they come into contact with a source 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.
b. The pickup consists of a large number of optical and precision
parts. Do not store or repair it, therefore, in any location
with a high 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 strong 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 a single 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 a grounded electrically conductive sheet.
c.Ground the metal part of the soldering iron in order to
safeguard against leakage of electricity from the heater.
CAUTION - USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

d. Repair personnel must wear grounding bands around their
wrists to discharge static picked up by their bodies. These
bands are grounded through a resistor (with a 1Mlt
resistance).
Note: Under no circumstances must be the grounding bands be
grounded without a resistor (with a 1MIF 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).
e. The pickup, which is a single integrated part, is kept in a
conductive bag. Use this bag to convey the pickup from one
place to another. in 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.
3. Cleaning the lens surface
a. Blow off dust on the lens using the kind of air brush which is
used for cameras.
b. Remove stubborn dirt with a cotton 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 may
seep inside the pickup.
@The lens is held in place by a very feeble support
spring. Therefore, when cleaning the lens, avoid
applying any more force by the cotton swab than is
necessary since this may bend the support spring out of
shape.

SERVICE MODE
Specifications
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 a service mode. As the service
mode entry state is discontinued after 1 second elapses, the system will enter a service 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, a rectangular wave with a frequency 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.
2. Timer debugging
- When the FAST key is pressed, the current time advances one minute and the seconds readout changes to 55 seconds. If the
key is held down the time advances continuously.
- The FAST key, a concealed key not actually mounted to the set.
Note: For timer debugging, the service mode entry state (entered by simultaneously pressing the
12k ohm
OPEN/CLOSE service mode entry key and the BAND key) is not necessary. L
3. Checking the key input signal connections |
- Enter this mode by pressing the MEMORY(TUNER) key during the service mode entry state. =—

6. CD tracking balance adjusting mode
- Enter this mode by pressing the PLAY/PAUSE key during the service mode entry state.
- If the power is off when this mode is entered, the power automatically comes on.
- In this mode, the tracking balance adjustment state (tracking is off) is automatically entered after the tray is completely closed.
lf the PLAY key is pressed in this state, the tracking 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, the tracking balance adjustment state can be entered by pressing the MEMORY key during playing. Pressing the
PLAY key in this state turns on the tracking servo and causes playing to begin.
- Turning off the power releases the CD tracking balance adjusting mode.
7. CD operation display mode
‘ Enter this mode by pressing the STOP key during the service mode entry state.
- If the power is off when this mode is entered, the power automatically comes on.
