Before starting optical adjustment, be sure to take anti-static measures.

Optical pickup tilt adjustment is needed after replacement of the following components.
1. Optical pickup unit
2. Spindle motor unit
3. Optical pickup peripheral parts (such as rail)
Notes
Adjustment is generally unnecessary after replacing other parts of the traverse unit. However, do adjustment if there is a
noticeable degradation in picture quality. Optical adjustments cannot be made inside the optical pickup. Adjustment isgenerally
unnecessary after replacing the traverse unit.

11.3. Storing and Handling Test Discs
·
Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.
1. Do not place discs directly onto the workbench, etc., after use.
2. Handle discs carefully in order to maintain their flatness. Place them into their case after use and store them vertically. Store
discs in a cool place where they are not exposed to direct sunlight or air from air conditioners.
3. Accurate adjustment will not be possible if the disc is warped when placed on a surface made of glass, etc. If this happens, use
a new test disc to make optical adjustments.
4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will not be playable.
