TTY Options
A TTY (also known as a TDD or Text Telephone) is
a telecommunications device that allows people
who are deaf, hard of hearing, or who have
speech or language disabilities, to communicate
by telephone.
Your phone is compatible with select TTY
devices. Please check with the manufacturer of
your TTY device to ensure that it is compatible
with digital cell phones. Your phone and TTY
device will connect via a special cable that plugs
into your phone’s headset jack. If this cable was
not provided with your TTY device, contact your
TTY device manufacturer to purchase the
connector cable.
Before using your phone with a TTY device,
configure TTY options.
Note: Enabling TTY Options may affect the
performance of headsets and other non-TTY
equipment plugged into your phone’s
headset jack.

To access the state Telecommunications Relay
Service (TRS) for assistance with TTY calls:
Ⅲ Dial 711, then press the
TALK Key and
press to reach an operator.
Caution! 911 Emergency Calling - it is
recommended that TTY users make
emergency calls by other means,
including Telecommunications Relay
Services (TRS), analog cellular, and land
line communications. Wireless TTY calls
to 911 may be corrupted when received
by public safety answering points
(PSAPs), rendering some
communications unintelligible. The
problem encountered appears related to
software used by PSAPs. This matter has
been brought to the attention of the FCC,
and the wireless industry and the PSAP
community are currently working to
resolve this.
