All the same parts are used and assemble these models.

* This product includes technology owned by Microsoft Corporation

and cannot be used or distributed without a license from MSLGP.

* We cannot supply PWB with component parts in principle. When

a circuit on PWB has failure, please repair it by component parts

base. Parts which are not mentioned in service manual are not

supplied.

* Specification and design are subject to change without notice for

further improvement.

* In case that the main unit is transported for repair, the lock pin

9. Cautions in handling the optical pickup

The laser diode of the optical pickup can be damaged by electr-

ostatic 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 ter-

minals 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 not foreign substances enter through the ventilati-

on 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.

PN-2708N-A/B

To engineers in charge of repair or inspe-

ction of our products.

Before repair or inspection, make sure to follow the in-

structions so that customers and Engineers in charge

of repair or inspection can avoid suffering any risk or

injury.

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) sh-

all 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 re-

placement 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.

CAUTION

Use of controls, adjustments, or performance of procedures other

than those specified herein, may result in hazardous radiation ex-

posure.

The compact disc player should not be adjusted or repaired by an-

yone except properly qualified service personnel.

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 obser-

ved 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 suscepti-

ble 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 C. Take care not to apply the iron tip

repeatedly(more than three times) to the same patterns. Also ta-

ke 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.
