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 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 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 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 dam-
age your eyesight.
9. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by elec-
trostatic charge caused 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 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 sol-
dering 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. 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 small amount of isopropyl alcohol to lens paper
and wipe the lens gently.

CHANGING THE RECEPTION AREA
Model PE-2561B-A(U.S model) is initially 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 or AM).
2. While pressing the [A-M] button and 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 hold 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.
