If training with a particular remote terminal always
takes too long, the initial modem rate may be too
high. Reduce the initial Tx modem rate using
these bits.
For the settings slower than 14.4 kbps, Switch 04
bit 4 must be changed to 0.

The machine uses inch-based resolutions for
scanning. If “inch only” is selected, the printed
copy may be slightly distorted at the other end if
that machine uses mm-based resolutions.

(0, 1): Use this setting if echoes on the line are
interfering with the set-up protocol at the start of
transmission. The machine will then wait for the
second DIS or NSF before sending DCS or NSS.

V.8 protocol
0: Disabled
1: Enabled If transmissions to a specific destination always
end at a lower modem rate (lower than 14,400
bps), disable V.8 protocol so as not to use V.34
protocol.
0: V.34 communication will not be possible.
