Muting or sending DTMF tones
The
Mute keys
and
Send keys
options allow you
to turn off and on the key tones. If the
Mute keys
option is selected, your phone does not transmit the
DTMF (Dual Tone Multi-Frequency) tones of the
keys, which allows you to press keys without
hearing annoying key tones during a call.

computerised telephone systems, the
Send
keys
option must be selected.

system, like a banking service.

select

or press the key.
2. Select
