Muting or Sending Key Tones

These options allow you to turn the key tones off or on. 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 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.

1.When you are connected to the teleservice system, press the Options soft key.

2.Press the Down key to highlight the Send DTMF option.

3.Press the OK soft key.

4.Enter the number you want to send and press the OK soft key.

The tones are sent.
