Setting Dial Tone detection
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.

Compatibility
If you are having difficulty sending or receiving a fax due to possible

Equalization for compatibility. The machine adjusts the modem
speed for fax operations.
