Muting or sending key 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.
Note: To communicate with answering machines or
computerised telephone systems, the Send
keys option must be selected.
Sending a sequence of DTMF tones
You can send the DTMF tones as a group after
entering the entire number you need to send.
This option is helpful for entering a password or an
account number when you call an automated
system, like a banking service.
To send the DTMF tones:
1. While connected to the teleservice system, press
the Options soft key or the Centre key.
2. Press the Down key to highlight the Send DTMF
option.
3. Press the OK soft key or the Centre key.
4. Enter the number you want to send and press
the OK soft key or the Centre key.
The tones are sent.
