Setting Dial Tone detectionC
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.
