Enter Maintenance Mode:

1. Unplug power from rear of Fax machine, hold the Menu button while plugging power back in. Continue to hold the Menu button until "Maintenance" appears in the LCD window.
2. There are no helps for the Maintenance mode. Follow parameter change procedures to the letter.

Changing Baud Rate from Automatic to 9600:

1. Enter 10 (one, zero). This will bring up WSW00 on the LCD window.
2. Change the 00 to 19. If the baud rate is set to automatic, the numbers that appear will be 11100010.
3. Change the 11100010 to 01100010. This sets the baud rate to 9600.
4. Press the "Set" button just below the LCD window.
5. Press "Stop".
6. Enter 99. This will exit Maintenance mode and make the fax ready to use again.

You can't, plus it will not help on a digital phone system. ALL fax machines are ANALOG devices.
