Handling Incoming Calls
DifficultySuggestions
The machine ‘Hears’ a voice as a

Dial Tone detectionB
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 factory  No Detection setting.

has the ability to convert it, the 
colour fax will be printed at your
