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

1Make a call to the desired number in the usual way (e.g., to your bank’s computer phone number).

2Enter 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.)

1Recall the memory location containing the phone number and DTMF string.

2Press the SEND key to dial the phone number.

3After 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.

4To 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.
