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 except the Mirror Time. 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.
