[Tangential screw adjustment]
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 message 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.
