Sending DTMF Tones

Placing p and w characters between DTMF digits

You may insert a pause of 2.5 seconds or a wait in front of,

or between DTMF digits.

For a pause, press the

✱

key three times quickly so that a p

is displayed. All digits following the pause will be sent as
DTMF tones.

For a wait character, press the

✱

key four times quickly so

that a w is displayed.

To send a DTMF sequence which contains wait characters:

Make a DTMF call in the normal way.

Wait for answer. Press the

DTMF

selection key as many

times as there are wait characters.
All digits following these characters will be sent as DTMF

tones.

Note: Some SIM cards do not allow pause or wait charac-
ters. If your SIM card rejects the characters, first select the

phone memory and then store the sequence.
