In using the manual operation menu, take care of the following
points. These commands do not provide protection, thus requiring
correct operation. The sector address or time code field is displayed
when a disc is loaded.
Note:
1.
Set correctly the disc type to be used on the Disc Type
screen.
2. In case of an alarm, immediately press the  x  button
to stop the servo operation, and press the  +/1  button to
turn the power off.
Basic operation:
(controllable from front panel or remote commander)
 +/1

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.
