Dial Tone detection B
When sending a fax, 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 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.

Telephone Line Interference

If you are having problems sending or
receiving a fax due to possible interference
on the telephone line, or if you are using a
VoIP system, we recommend that you
change the modem speed to minimise errors
in fax operations.

g Press Normal or Basic(for VoIP).
 Basic(for VoIP) reduces the
modem speed to 9,600 bps and
turns off colour fax receiving and
Error Correction Mode (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.

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