Tone Dial or Pulse Dial?
If the setting of this feature is incorrect, the machine cannot dial.
There are two basic types of telephone company exchange:
Exchanges using Tone dialing (also known as DTMF, TT or sometimes
PB)
Exchanges using Pulse dialing (also known as PD or DP)
The telephone line type setting in your fax machine must match the type of
exchange that you are connected to. If you are not sure what type your local
exchange is, ask the telephone company.
