This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
[CLEAR]
key, they cannot be restored after initialization.
So, before clearing, make a note of the adjusted data.
For reference, the drive has been designed so that the gain center
value is 20 and offset value is 80. Other values will be in a range of
10 to 80. If extreme value such as 00 or FF is set, adjustment will be
faulty. In such a case, check for disc scratch or cable disconnection,
then perform adjustment again.

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.
