7. ADDITIONAL FEATURES
Sending DTMF Tones
The Dual Tone Multi Frequency (DTMF) feature allows you to send
touch tones which can be used to control equipment such as
bank-by-phone or voicemail by using your cellular phone.
There are two alternative ways to send DTMF tones:
1. Manual Transmission
1
Make a call to the desired number in the usual way (e.g., to
your bank’s computer phone number).
2
Enter the digits you want to be sent as DTMF tones (e.g., your
bank account number and password).
2. Automatic Transmission
You can send a string of digits as DTMF tones by storing the string
in the phone’s memory and then recalling it for automatic DTMF
transmission.
•
When storing the string, insert a wait character between the
access phone number and DTMF string. (See Adding a Wait on
page 43.)
1
Recall the memory location containing the phone number and
DTMF string.
2
Press the SEND key to dial the phone number.
3
After the phone number ha sdisappeared from teh display, wait
for the tone and press the SEND key.
•
If the keypad tones have been set to off, the DTMF tones will
be sent, but you will not hear them.
4
To end the call, press the END key after the DTMF transmission
is completed and the phone has returned to normal call mode.
Note: When recalling a DTMF number from the memory during a
call, do not recall it by first entering the location number
and then pressing the key, because the location
number will then be sent as DTMF tones.
