Ive had the same problem and no it doesnt show you in the manual, which i think is pretty poor. Heres what to do :
Dial mode
Your BT Freestyle 310 is pre-set to Tone (DTMF) dialing.
If required, you can change this setting to Pulse dialing.
1. Press Menu. Scroll to Settings menu and press OK.
2. Scroll to Setup base and press OK.
3. Scroll to Dial mode and press OK.
4. Scroll or to highlight Tone or Pulse, then press OK.
5. Press to return to standby.
It makes it a lot easier!!
