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 tan-
gential 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 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-

Hence, change discs following the given messages on OSD, and
the adjustment is finished if there is no problem.
