Sending DTMF tones
The Dual Tone Multi Frequency (DTMF) tones al-
low you to communicate with voice mailboxes,
computerised telephony systems, etc. Sending
DTMF tones is not possible during a conference
call. Besides the numbers 0 - 9, you can also use
the characters
p
,
w
,
*
and
#
(for information on
the functions of these characters, see chapter 3
"Contacts: Contact cards - Storing DTMF tones").
To send a DTMF sequence when you have an ac-
tive call (remember that the active call must be
selected):
�
Key the digits from the communicator inter-
face keyboard. Each keystroke will generate a
DTMF tone which will be transmitted directly.
Or alternatively,
�
Press
Send DTMF
. A list of stored DTMF se-
quences is shown (for information on how to
store DTMF sequences, see chapter 3 "Con-
tacts: Contact cards - Storing DTMF tones").
�
Select a DTMF sequence. You can edit the se-
quence, or, if there are no stored sequences,
you can manually enter the DTMF string into
the field.
�
Press
Send
to send the DTMF sequence shown
in the input field, at the bottom of the display.
Incoming faxes, short messages and data
Faxes, short messages and incoming data are re-
ceived automatically, provided that the phone
interface is on and within cellular coverage area.
While a data/fax connection is active (check the
call status indicator), you cannot make calls.
If you want to make a voice call, you can either
wait until the data/fax call ends, or you can ter-
minate the data/fax call by starting to make a
call normally. When you press
Call
, you will be
asked if you want to terminate the data call.
Press
Terminate
to confirm.
