Dial Tone detection B
When you send a fax automatically, by
default your machine will wait for a fixed
amount of time before it starts to dial the
number. By changing the Dial Tone setting to
Detection you can make your machine dial
as soon as it detects a dial tone. This setting
can save a small amount of time when
sending a fax to many different numbers. If
you change the setting and start having
problems with dialling you should change
back to the default No Detection setting.

receiving a fax due to possible interference
on the telephone line, we recommend that

14,400 bps. (Default)
