Getting More Out of Your Phone
Using TTY Mode
You can use an optional TTY device with your
phone to send and receive calls. You must plug
the TTY device into the phone’s headset jack and
set the phone to operate in one of three TTY
modes.
Notes:
•
Use a TSB-121 compliant cable (provided by the TTY
manufacturer) to connect the TTY device to your
phone.
•
Set the phone volume to level 4 (middle setting) for
proper operation. If you experience a high number of
incorrect characters, adjust the volume as necessary
to minimize the error rate.
•
For optimal performance, your phone should be at
least 12 inches (30 centimeters) away from the TTY
device. Placing the phone too close to the TTY device
may cause high error rates.

Setting TTY Mode

When you set your phone to a TTY mode, it operates in
that mode whenever the TTY device is connected.
The
TTY Setup
menu includes the following options:
When your phone is in a TTY mode, the international
TTY symbol and the mode setting are shown in the
display during an active digital TTY call. You can press
TTYMODE
(
-
) to change the mode setting.

Switching to TTY Mode During a Voice Call

Returning to Voice Mode

To return to normal voice mode, select
Voice
from the
TTY Setup
menu.
Using Fixed Dialing
When you turn on fixed dialing, users can only
call numbers stored in the fixed dial list. Use this
feature to limit outgoing calls to a predefined list
of numbers, country codes, area codes, or other
prefixes.

Turning Fixed Dial On or Off

Using the Fixed Dial List

You must turn on fixed dialing to open the fixed dial list
(see above)
You create and edit fixed dial entries just like phonebook
entries. Fixed dial entries are stored on your SIM card, and
do not have
Type
,
Voice Name
, or
Ringer ID
information.
Using DTMF Tones
You can send numbers to the network as dual tone
multi-frequency (DTMF) tones during a call. Use DTMF
tones to communicate with automated systems that
require you to submit a PIN code or credit card number.
To set DTMF tones to be long, short, or off:
Short
sends a short fixed-duration tone for each keypress.
Long
sends each tone for as long as you depress the key.
Short DTMF tones work with most automated systems.
Some systems (such as home answering machines) may
require long tones for proper activation.
