The adjustment must be executed more than once after default
data were written. External vibration or shock to the player must
not be given. Reference value for DVD is from 10 to 20, and for
CD, from 28 to 4F.
Check that the value of CD is larger than that of DVD.
When those values are beyond a range perform this 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.

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 dis-
connection, then perform adjustment again.
