13.4.1.1. Adjustment procedure
1. While pressing STOP button on the main unit, press "5" on
the remote control unit.
2. Confirm that "J_xxx/yyy_zz" (display1/display2) is shown on
the front display.
For your information:
"yyy" and "zz" shown to the right have nothing to do with
the jitter value. "yyy" is the error counter, while "zz" is
the focus drive value.
Note:
Jitter value appears on the front display.
3. Play test disc T30 (center periphery).
4. Adjust tangential adjustment screw so that the jitter value is
minimized.
5. Play test disc T30 (center periphery).
6. Adjust tilt adjustment screw 1 so that the jitter value is
minimized.
7. Play test disc T30 (center periphery).
8. Adjust tilt adjustment screw 2 so that the jitter value is
minimized.
9. Repeat adjusting tilt adjustment screws 1 and 2 alternately
until the jitter value is minimized.
13.4.1.2. Important points
1. Make tangential adjustment first, and then make tilt
adjustment.
2. Repeat adjusting two or three times to find the optimum
point.
3. Finish the procedure with tilt adjustment.
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.
13.4.1.3. Check after adjustment
Play test disc or any other disc to make sure 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.
13.4.1.4. Procedure for screw lock
1. After adjustment, remove top cover, tray, clamper base and
traverse unit in this sequence.
2. Lay the traverse unit upside down, and fix adjustment screw
with screw lock.
3. After fixing, reassemble traverse unit, clamper base, tray
and top cover.
