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:
1.1 Make the call in the usual way.
1.2 When 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:
2.1 Make the call in the usual way.
2.2 When 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).
2.3 To 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.
