Unleaded solder

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

· Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350°C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

· Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than

ordinary solder so use caution not to let solder bridges occur such

as on IC pins, etc.

· Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

Flexible Circuit Board Repairing

·Keep the temperature of the soldering iron around 270 °C dur-

ing repairing.

· Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

· Be careful not to apply force on the conductor when soldering

or unsoldering.

Notes on chip component replacement

·Never reuse a disconnected chip component.

· Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

This appliance is classified as a CLASS 1 LASER product.

The CLASS 1 LASER PRODUCT MARKING is located on

the rear exterior.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous

radiation exposure.

On AC poweradaptor

·Use only the AC power adaptor supplied or

recommeded in "Accessories (supplied/

optional)." Do not use any other AC power

adaptor. It may cause a malfunction.

SECTION 1

SERVICING NOTE

The laser diode in the optical pick-up block may suffer electrostatic

breakdown because of the potential difference generated by the

charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic breakdown and also use

the procedure in the printed matter which is included in the repair

parts.

The flexible board is easily damaged and should be handled with

care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

BEFORE REPLACING THE OPTICAL PICK-UP BLOCK

Please be sure to check thoroughly the parameters as par the "Optical

Pick-Up Block Checking Procedures" (Part No.: 9-960-027-11)

issued separately before replacing the optical pick-up block.

Note and specifications required to check are given below.

· FOK output: IC601 yg pin

When checking FOK, remove the lead wire to disc motor.

· RF signal P-to-P value: 0.45 to 0.65 Vp-p

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

During normal operation of the equipment, emission of the laser

diode is prohibited unless the upper lid is closed while turning ON

the S820. (push switch type)

The following checking method for the laser diode is operable.

· Method:

Emission of the laser diode is visually checked.

1. Open the upper lid.

2. With a disc not set, turn on the S820 with a screwdriver having a

thin tip as shown in Fig.1.

3. Press the u button.

4. Observing the objective lens, check that the laser diode emits

light.

When the laser diode does not emit light, automatic power control

circuit or optical pickup is faulty.

In this operation, the objective lens will move up and down 4

times along with inward motion for the focus search.
