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.

Telephone line interference B
If you are having problems sending or
receiving a fax due to possible interference
on the telephone line, we recommend that
you adjust the Equalization for compatibility
to reduce the modem speed for fax
operations.

on your telephone line, you may
prefer to use it only when needed.
Normal sets the modem speed at
14400 bps.
High increases the modem speed to
33600 bps. (default)
Press OK.
