SERVICE NOTES
1. Make sure that the power lead is connected properly to
power source, otherwise damage to radio may result. If a
battery eliminator is used as a power source in place of a
battery, it must be filtered and regulated. (The power sup-
ply capacity should be more than 5 amps.)
2. Integrated circuits (ICs) are used in this unit. Because the
ICs are direc-coupled devices, as to all electronic equip-
ment, reading within 10% of the indicated values are ac-
ceptable. Allowance must also be made for variations in
supply voltage. It is expected that any breakdown within
the IC results in drastic changes of the operating voltages
at the terminals.
3. When replacing a power output IC, remember to use the
IC specified in the parts list; Coat the IC-fin with silicon
grease.
WARNING
ln using meters, signal generator and any tool in servicing
Ics, extreme care is needed. DO NOT SHORT THE IC TER-
MINALS TO THE PATTERN ON THE PC BOARD OR TO
EACH OTHER. THE IC WILL BE INSTANTANEOUSLY DE-
STROYED.
ALIGNMENT PROCEDURE
Alignment is performed at factory with laboratory equipment.
Therefore, before alignment is attempted, the unit should be
thoroughly checked for circuit troubles.
NOTES:
1. Check for specified source voltage-DC, 14.4volts.
2. Connect an AC voltmeter (AC VM) across speaker or
dummy load (4 ohms. 20W, wirewound resistor)...see Fig.
1-3. (ELECTRICALADJUSTMENTS)
3. Signal input must be kept as low as possible to avoid over-
load and clipping (use highest sensitivity of output indica-
tor).
4. Repeat adjustment to ensure good results.
5. Non-metallic alignment tools must be used (especially at
FM alignment).
6. For alignment location details, refer to CIRCUIT BOARD
PARTS LOCATION.
SERVICE NOTES AND PRECAUTIONS
INSTALLATION PROCEDURE
1. To prevent a short circuit, remove the key from the igni-
tion and disconnect the battery.
2. Make the proper input and output wire connections for
each unit.
3. Connect the wiring harness wires in the following order:
ground, speakers, battery, ignition.
4. Connect the wiring harness connector to the unit.
5. Install the unit in your car.
6. Reconnect the battery.
7. Disinstall by reversing the installation procedure.
CAUTI0N
• The rear-panel which also heatsink is very hot. Don’t burn!!
• If your car’s ignition does not have an ACC position, con-
nect the ignition wires to a power source that can be turned
on and off with the ignition key. If you connect the ignition
wire to a power source with a constant voltage supply, as
with battery wires, the battery may die.
• If the console has a lid, make sure to install the unit so
that the cover will not hit the lid when closing and open-
ing.
• If the fuse blows, first make sure the wires aren’t touching
to cause a short circuit, then replace the old fuse with one
with the same rating.
• Do not let unconnected wires or terminals touch metal on
the car or anything else conducting electricity. To prevent
a short circuit, do not remove the caps on the ends of the
unconnected wires or the terminals.
• Connect the speaker wires correctly to the terminals to
which they correspond. The unit may be damaged or fail
to work if you share the wires or ground them to any
metal part in the car.
• After the unit is installed, check whether the brake lamps,
blinkers, wipers, etc. on the car are working properly.
• Insulate unconnected wires with vinyl tape or other simi-
lar material .

SERVICE NOTES AND PRECAUTIONS
LASER BEAM SAFETY PRECAUTIONS
NOTES FOR TRANSPORT AND STORAGE
1. The pickup should always be kept in its conductive bag
until use.
2. The pickup should never be subjected to external pres-
sure or impact.
REPAIR NOTES
1. The pickup incorporates a strong magnet, and so should
never be brought close to magnetic materials.
NG
Magnet
NG
2. The pickup should always be handled correctly and care-
fully, taking care to avoid external pressure and impact. If
it is subjected to strong pressure or impact, the result may
be an operational malfunction and/or damage to the
printed circuit board.
3. Each and every pickup is already individually adjusted to
a high degree of precision, and for that reason the adjust-
ment point and installation screws should be absolutely
never be touched.
4. Laser beam may damage the eyes!
Absolutely never permit laser beams to enter the eyes!
Also NEVER switch ON the power to the laser output part
(lens, etc.) of the pickup if it is damaged.
Laser Beam
NEVER look directly at the
laser, and do not let contact
fingers of other exposed
skin.
NG
5. Cleaning the lens surface
If there is dust on the lens surface, the dust should be
cleaned away by using an air brush (such as one used for
camera lens). The lens is held by a delicate spring.
Conductive Sheet
6. Never attempt to disassemble the pickup.

SERVICE NOTE AND PRECAUTIONS
STATIC ELECTRICITY
The CD pickup might suffer destruction by static electricity during spare-parts maintenance or replacement, although it is stable
when connected to the circuit in the CD unit. The destruction might be caused because the laser diode terminal will be electri-
cally open. To prevent the terminal from being open, do the following steps:
1. When you replace the CD pickup, or remove the CD unit from the car stereo unit for any maintenance purpose, solder the
copper foil pattern indicated in Fig. 1 and Fig. 2 below to short-circuit the connector PCB and flexible wire of the CD unit.
Perform your intended maintenance work with the flexible wire short-circuited.
2. If the original CD pickup may possibly be reused, make a short circuit in the area indicated in Fig. 3 first. Then remove the
pickup and perform the work.
3. The CD Pickup OPTIMA-715K2, which is supplied as one of the spare parts, is already short-circuited with the copper foil
pattern pre-soldered indicated in Fig. 3 below. To handle this CD Pickup, keep the short circuit as it is. Then attach the
Pickup to the unit and connect the flexible wire to the connector.
4. After performing the work, eliminate the short circuit by removing the solder at its respective short-circuited area described
in 1, 2 and 3 above.
5. Insert a CD. If the E-01 or E-02 error should appear on the display on the face plate, check the area mentioned in 4 above,
where the short circuit may not have been eliminated.
6. Note that the semi-fixed VR equipped with the CD Pickup OPTIMA-715K2 must not be turned. You cannot make any
adjustment to the semi-fixed VR, which is completely adjusted when shipped at the factory.
