[Bit 1]
Selects whether or not the echo protect tone is transmitted for high-speed transmission
(9600 or 7200 bps).
If errors due to line conditions occur frequently during fax transmission, select “Transmit-
ted”.
When “Transmitted” is selected, a non-modulated carrier is transmitted as a synchroniza-
tion signal before the image transmission.

tions:
##100, ##104, ##281, ##282, ##283, ##750, ##755, ##760, ##765
[Bit 7]
