The drive can be automatically adjusted, except disc change and
tangential skew adjustment. For a disc, use the disc for adjust-
ment.
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 8 will appear.

The tray opens after the [ENTER] key is pressed and the initial-
ization is finished. Then, place the DVD_SL disc for adjustment.
Press the [ENTER] key to start adjustment. During adjustment,
the tangential skew adjustment screen is displayed. Make this ad-
justment 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 screw-
driver with the disc. After adjustment, a message to apply a screw
locking agent will be displayed if jitter value is within the specifi-
cation. 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.
