6-3. Drive Auto Adjustment
The drive can be automatically adjusted, except disc change and
tangential skew adjustment. For a disc, use the disc for adjustment.
In case of abnormality, press the [stop] key to stop adjustment.
If the drive does not stop, prevent secondary failure by taking proper
action such as disconnection of the power cable. This adjustment
should be made after repair is finished and no trouble is present in
the drive.
A trouble, if present, causes NG and the adjustment to be aborted.
As the secondary failure could occur, perform automatic adjust-
ment after the drive is completely repaired.
With the initial menu displayed, press [1] on standard commander,
and the screen as shown in Figure 5 will appear.
The tray opens after the ENTER key is pressed and the initializa-
tion is finished. Then, place the DVD_SL disc for adjustment. Press
the ENTER key to start adjustment. During adjustment, the tangen-
tial skew adjustment screen is displayed. Make this adjustment only
when the pickup was replaced.
As for adjustment, rotate the T-SKEW adjusting screw on the pickup
so that the displayed jitter becomes minimum (CCW makes jitter
smaller). Avoid extreme rotation or interference of screwdriver with
the disc. After adjustment, a message to apply a screw locking agent
will be displayed if jitter value is within the specification. Then,
apply a drip of locking agent to the recess of screw. Hence, change
discs following the given messages on OSD, and the adjustment is
finished if there is no problem.
Note that if “All” is selected, the data of previous adjustment are
erased and initial values are set.
