DTMF On or Off
Since the ability to communicate with
automated systems is frequently
needed, you can usually set and main-
tain the DTMF tone transmit selection to
on. If you use the phone scratchpad fea-
ture (see “Dialing a phone number on
notepad” on page 8) to key in a phone
number during a call in progress, you
can turn off the DTMF selection, as
needed, to avoid generating audible
tones that can be disruptive during a
phone conversation.
Text Message
Roll Off Order
As described in “Text Messages” on page 25,
your phone can receive text messages if text
messaging service is available through your cel-
lular service provider. When the phone text mes-
sage storage is full and more text messages are
delivered, existing messages are automatically
replaced with the new messages. The order in
which the existing messages are replaced,
referred to as roll off order, can be selected
based on message arrival time or message
urgency.

Example of Communicating with An Automa ted
System Using DTMF Touch Tones
To contact your credit card company for account balance informa-
tion, you dial the phone number. The credit card automated system
answers by prompting you to enter the account number. If the DTMF
tones selection in your phone is set to on, you can successfully com-
municate with the automated system. If the DTMF tones selection in
your phone is set to off, then the automated system cannot recognize
any number entries.
