To engineers in charge of repair or inspecti-

on of our products.

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

ructions 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.

Theuseofunspecifiedpartsshallberegardedasremodelingfor

which we sha ll not be liable. The o nus of product liability (PL) shall

not be our responsibility in cases where an accident or failure is as

a r esult of uns pecified par t s being used.

2. Place t he 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 u sing clamps to keep away from

heated and high voltage parts. Ensure that they are placed back

in their original posi tion s after repair or inspection.

If extended damage is caused due to negligence during repair, the

legal res ponsibility 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 r easons there

is no possibility of secondary ploblems around the repaired spo ts.

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 ob-

served 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 suscep-

tible 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

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 re flection surface throu gh 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 dam-

age your eyesight.

9. Cautions in handling the optical pickup

The l aser diode of the optical pickup can be damaged by ele c-

trostatic charge cau sed by your clothes and body. Make sure

to avoid electrostatic charges on your clothes or body, or dis-

charge static electric ity before handling the optical pickup.

9-1.Laser diode

The laser diode term inals are shorted for transportation in

order to prevent electrostatic damage.

After replacement, open the shorted circuit. When removin g

the pickup from the mechanism, short the terminals by sol-

dering them to p rev ent 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. En-

sure 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 sm all amount of isopropyl alcohol to lens paper

and wipe the lens gently.

CHANGING THE RECEPTION AREA

Model PE-2561B-A(U.S model) is initi ally set to USA frequency

intervals of 10kHz for AM and 200kHz for FM. When using it

outside the USA, the frequency reception range can switched to

the intervals below.

Setting the reception area

1. Press the [BND] button and select the desired radio band

(FM o r AM).

2. While pressing the [A-M] button a nd hold the number "2" of the

[DIRECT] button for 2 seconds or longer, the reception area

switches from inside the USA to outside the USA.

3. While pressing the [A-M] button and h old the number "1" of the

[DIRECT] button for 2 seconds or longer, the reception area

switches from outside the USA to inside the USA.

* Any station preset memories are lost when the reception

area is changed.
