NOTES ON HANDLING THE 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 pick-up 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 a new one.

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 sig-
nificant deterioration occurs in the RF waveform.

Apply CD lens cleaner B-4 (Part No.:J-2501-000-A) to cotton swabs
(narrow type) (Part No.:J-2501-023-A) to be lightly wet. Use a force
(about 5 g (0.18 oz)) 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.
