Selector 8: Line polarity reversal detector (Not used.)
When the remote station breaks the connection, a line polarity reversal occurs. Enabling the polarity
reversal detector with this selector allows the machine to detect the polarity reversal if detected when
the user is leaving a message on the station's answering machine.

Selectors 1 and 2: Monitoring the PC ON/OFF state
For the related functions, refer to WSW36, selectors 2 and 3.
Selector 3: Parallel port output pins kept at high level
Setting this selector to "0" will keep all parallel output pins of the machine at high level. Use this
setting if Resource Manager (bundled with MFC models) installed to WindowsNT running on the
connected PC fails to monitor the power ON/OFF state of the machine.
Selector 4: Previous filtering parameters for white level compensation
At the start of scanning operation, the machine usually initializes white and black level data stored in
the EEPROM by scanning the white reference film attached to the inside of the scanner top cover.
After long use of the machine, however, the film may be contaminated with dust or dirt. Accordingly,
incorrect white level data will be set up so that white vertical streaks will be brought on the scanning
result.
Setting this selector to "0" (Enabled) will apply previously saved white level data instead of new
incorrect compensation.
