※ Prevent damage caused by static electricity when re-
pairing the pick-up.
The pattern of the pick-up is short-circuiting for prevention.
Remove the soldering with a solder iron whose insulation resistance is larger than 10M
Ω(DC500V) after com-
plete connection to the main PWB
For repair table shall use copper or conductive sheet
(with impedance is lower to 100M
Ω from 1MΩ)such as
a sheet.
Be sure to put on a wrist-strap for prevent electric
static's.(with impedance is to 100M
Ω from 1MΩ) The
strap works to drain away the static electricity build-up
on the human body.
And as static electricity build-up on clothes is not drained
away, be careful and not your clothes to touch the pickup.
Position of short soldering for pick-up protection position is different by model.
Some units have two short soldering points.
Always short LD circuit to open the short circuit and removes by soldering iron.

■COMPUTER ANTI-THEFT SYSTEM
This unit has a built-in Computer Anti-Theft System(CATS)
which makes the radio inoperative if power to the unit is
interrupted for any reason whatsoever(including disconnection and reconnection of the car battery). The radio will remain inoperative unless you enter the correct CATS number.
RELEASE the CATS
1. Turn on the power switch, "COdE" appear on the display.
2. Enter the code number of five figures using the preset
buttons.
3. If the entered code number is correct, make a beep sound
(about 1 second) and radio operating.
4. If the entered code number is incorrect, "Err1" appear
on the display for 1 secound and make a beep sound. It
repeats three times.
5. To enter the code number again, "COdE" reappears after 1 second on the display. Enter the correct code number.
6. If you enter an incorrect code number ten times in succession, "ErrE" appear on the display.
7. The system will not accept another code input for one
hour. If at the end of that hour make a beep sound (about
1 second) and you enter an incorrect code number again,
you will have to wait another hour to try once more and
so on.
■ADJUSTMENT
Clock accuracy
Item Procedure
Measuring
instrument
1. Turn on the ACC switch.
2. Set a universal timer to TP101(T-BASE), adjust TC102 so that a reading of the
meter is 0 to 1.0 sec./day.
Chronometer
1. Use specified parts.
The system uses parts with special safety features against
fire and voltage. Use only parts with equivalent characteristics when replacing them.
The use of unspecified parts shall be regarded as remodeling for which we shall not be liable. The onus of
product liability (PL) shall not be our responsibility in cases
where an accident or failure is as a result of unspecified
parts being used.
2. Place the parts and wiring back in their original positions
after replacement or re-wiring.
For proper circuit construction, use of insulation tubes,
bonding, gaps to PWB, etc, is involved. The wiring connection and routing to the PWB are specially planned
using clamps to keep away from heated and high voltage
parts. Ensure that they are placed back in their original
positions after repair or inspection.
If extended damage is caused due to negligence during
repair, the legal responsibility shall be with the repairing
company.
3. Check for safety after repair.
Check that the screws, parts and wires are put back securely in their original position after repair. Ensure for
safety reasons there is no possibility of secondary
ploblems around the repaired spots.
If extended damage is caused due to negligence of repair, the legal responsibility shall be with the repairing
company.
4. Caution in removal and making wiring connection to the
parts for the automobile.
Disconnect the battery terminal after turning the ignition
key off. If wrong wiring connections are made with the
battery connected, a short circuit and/or fire may occur.
If extensive damage is caused due to negligence of repair, the legal responsibility shall be with the repairing
company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnormality
is observed in their appearance. Always replace them
with new ones. (The chip parts include resistors, capacitors, diodes, transistors, etc). The negative pole of tantalum capacitors is highly susceptible to heat, so use special care when replacing them and check the operation
afterwards.
6. Cautions in handling flexible PWB
Before working with a soldering iron, make sure that the
iron tip temperature is around 270
℃. Take care not to
apply the iron tip repeatedly(more than three times)to the
same patterns. Also take care not to apply the tip with
force.
7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the
unit.
8. Cautions in checking that the optical pickup lights up.
The laser is focused on the disc reflection surface through
the lens of the optical pickup. When checking that the
laser optical diode lights up, keep your eyes more than
30cms away from the lens. Prolonged viewing of the laser within 30cms may damage your eyesight.
9. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by
electrostatic charge caused by your clothes and body.
Make sure to avoid electrostatic charges on your clothes
or body, or discharge static electricity before handling the
optical pickup.
9-1. Laser diode
The laser diode terminals are shorted for transportation in order to prevent electrostatic damage.
After replacement, open the shorted circuit. When
removing the pickup from the mechanism, short
the terminals by soldering them to prevent this
damage.
9-2. Actuator
The actuator has a powerful magnetic circuit. If a
magnetic material is put close to it. Its characteristics will change. Ensure that no foreign substances enter through the ventilation slots in the
cover.
9-3. Cleaning the lens
Dust on the optical lens affects performance. To
clean the lens, apply a small amount of isopropyl
alcohol to lens paper and wipe the lens gently.
