SERVICE NOTE

CAUTION
Use of controls or adjustments or performance of proce-
dures other than those specified herein may result in hair,
ardous radiation exposure.

Notes on Chlp Component Replacement

- Never reuse a disconnected chip component.

0 Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

NOTES ON HANDLINGTHE OPTICAL PICK-UP BLOCK OR
BASE UNIT

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.

NOTES ON PICK-UP FLEXIBLE BOARD

The pickvup flexible board in this set is secured to the optical pick-up
with an adhesive tape. Once the tape is removed, an adhering force
becomes weak, and it cannot be reused.

Therefore, if the optical pick-up is replaced, replace also the pick-up
flexible board with anew one.

NOTES ON CLEANING THE OBJECTIVE LENS

cotton swabs
objective lens

2M5 actuator

optical plck-up

Z-axis cover
slide bass

Apply CD lens cleaner 13-4 (Part No.:J-2501v000-A) to cotton swabs
(narrow type) (Part No.:J-2501-023~A) to be lightly wet Use a force
(about 5 g (0.18 02)) to make the objective lens in contact with the
bottom lightly, and clean the lens by spirals as following below.

Replace the cotton swab and repeat this cleaning two or three times.

surface of objective lens

Notes:

Do not force to push the objective lens. Otherwise, the plate spring
supporting the objective lens will be bent, causing a deteriorated RF
waveform.

Never touch anything other than the objective lens. Otherwise, a
significant deterioration occurs in the RF waveform.
