Send DTMF (Menu 17)
You can transmit numerical information as a series of tones, using the DTMF facility (e.g. to check for messages in your answering machine). There are two ways to send DTMF tones:
1.Manual Dialing:
1.1Make the call in the usual way.
1.2When the call has been answered, enter the numbers. Each number is sent immediately, as a DTMF tone. The length of the tone depends on how long you press the key.
2.Automatic Dialing:
2.1Make the call in the usual way.
2.2When the call has been answered, use the RCL key to recall a stored ‘DTMF’ number from a memory location (e.g. for location 23, press RCL 2 3).
2.3To send the whole number (displayed) as DTMF tones, press MENU SEND, or MENU 1 7. A series of tones, each tone representing a digit of the DTMF number, will be heard.
The special characters ‘+’, ‘p’ and ‘w’ are used for DTMF dialing; these are available on the * key.
