CLEAR: Default Set     page.2/2

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.
