follows:

 If you are not sure of your dialing system, set the unit to tone dialing. Make a trial call. If the call
connects, leave the setting as is. Otherwise, set the unit to pulse dialing.
 If your telephone system requires pulse dialing and you need to send DTMF tones in certain
situations during a call, you may “switch-over” to tone dialing. (Refer to the Dterm Headset
Cordless Owner’s Guide for Tone Dialing Switch-over section.)
