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 when dialling, you should change it
back to the No Detection setting.

receiving a fax due to possible interference
on the telephone line, you can change the
compatibility setting which reduces the
modem speed to minimise errors.

 Basic(for VoIP) cuts the
modem speed to 9,600 bps and
turns off colour fax receiving and
ECM, except for colour fax-sending.
Unless interference is a recurring
problem on your telephone line, you
may prefer to use it only when
needed.
To improve compatibility with most
VoIP services, Brother recommends
changing the compatibility setting to
Basic(for VoIP).
 Normal sets the modem speed at
14,400 bps.
 High increases the modem speed to
33,600 bps. (factory default)

NOTE
VoIP (Voice over IP) is a type of phone
system that uses an Internet connection,
rather than a traditional phone line.
