11.2.1. Items for optical adjustment
•

•
•
"Optical pick-up tilt adjustment" is necessary when any of the following parts are replaced.
1. Optical pick-up
2. Disc motor
3. Traverse motor
4. Optical pick-up peripheral parts (rails, etc.)
Note:
Adjustment of other parts in the traverse is not normally necessary, but if deterioration of the picture is observed, make the
necessary adjustments. Optical adjustment of the optical pick-up is impossible. Replacing the traverse unit does not usually
require adjustment.
11.2.2. Items for electrical adjustment
11.3. Storage and maintenance of the test discs
•
•
•
•
The surface of DVD test discs is required to be very precise. Take every precaution when storing and maintaining them.
1.
After use, do not place the disc directly on the work surface.
2.
To keep the surface of the disc flat, treat with care and store in the case in a vertical position immediately after use. Keep in a cool
place away from direct sunlight and air conditioners.
3.
If the disc appears warped when laid on glass or other flat surfaces, accurate adjustment is no longer possible. Replace with a new
test disc for further optical adjustment.
4.
If adjustments are made with a warped disc, the adjustments will reflect this inaccuracy and playback of other discs may be
impossible.
