On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is displayed.
This is not displayed where the spindle is not locked. The spindle
could run overriding the control if the spindle system is faulty or
RF is not present. In such a case, do not operate CLVA.

menu and make a check for three types
of discs (SL, DL, CD).
Select the loaded disc. The adjusted
