This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
CLEAR “R” key on the remote commander, they cannot be restored
after initialization is executed. So, before clearing, make a note of
the adjusted data before you start initialization. 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 broken cable, poor connection of
flexible board, then perform adjustment again.
