Using Your Phone

When the phone is connected with other devices or services, you
can send DTMF (Dual Tone Modulation Frequency) strings.
DTMF strings are keypad tones that can be sent via the microphone
as you dial another number. Your phone will emit the tones in
order to communicate with answering machines, pagers,
computerized telephone services, and so forth.

Enter the phone number and then press 

 to send the DTMF

string.

You can access the Phone Book, Calls, and Messages menus during
