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.

This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with 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.
