DTMF DIALING

You can transmit numeric information as a series of tones
using the DTMF facility (for example to check for messages
in your answering machine).
There are two alternative ways to use the DTMF facility.
(I) Sending Direct Entries
³ Make the call in the usual way (see "Placing a Call'',
page 8).
· Key in numbers onto the display. Each number is
directly sent as a DTMF tone. The length of the tone
depends on how long you press the key.
(II) Sending Stored Information
³ Recall a number from a memory location and send it
as DTMF tones.
· Make the call in the usual way (see "Placing a Call'',
page 8).
» Recall the DTMF number from memory (RCL followed
by the memory location number).
¿ Send the DTMF tones by pressing MENU followed by
SEND. A series of tones, each representing a number, will
be heard.
Using Pause and Wait Characters between DTMF Digits
If you need to place a pause (P = 2.5 seconds) between
DTMF digits press MENU # to create the "p'' character in
the sequence. If you want to add a DTMF number to a
stored phone number, place a wait "w'' character in front
of the DTMF number by pressing MENU # #.
When you recall the information (telephone number and
DTMF numbers) from memory (RCL), press SEND to call
the number stored before the wait character.
