4.3. Check after Adjustment
Play a test disc or any other disc to make sure that there is
no picture degradation in the inner, middle and outer
peripheries, and no audio skipping. After adjustment is
finished, lock each adjustment screw in position using
screw lock.
4.4. Procedure for Screw Lock
1. After adjustment, remove the top cover, tray, clamper
base and traverse unit in this sequence.
2. Lay the traverse unit upside down, and lock the
adjustment screw with screw lock.
3. After locking, reassemble the traverse unit, clamper
base, tray and top cover.
• Jitter value depends on the model:
1. If the jitter value changes like B, the optimum point is
easy to find.
2. If the jitter value changes like A, set the optimum
point near the middle.
