Notes on chip component replacement

•Never reuse a disconnected chip component.

•Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 ˚C

during 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.

CAUTION

Use of controls or adjustments or performance of procedures

otherthanthose specified hereinmayresultin hazardous radiation

exposure.

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 viscou-s (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.

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

break-down because of the potential difference generated by the

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

During repair, pay attention to electrostatic break-down 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.

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

Laser component in this product is capable

of emitting radiation exceeding the limit for

Class 1.

This appliance is

claassified as a CLASS 1

LASER product. This

label is located on the

rear exterior.
