TTY Mode
A TTY (teletypewriter, 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 supports digital wireless transmission. Your phone and TTY device
will connect using a special cable that plugs into your phone’s audio jack. If this cable was not
provided with your TTY device, contact your TTY device manufacturer to purchase the
connector cable.

Warning:
911 Emergency Calling
It is recommended that TTY users make emergency calls by other means,
including Telecommunications Relay Services (TRS), analog cellular, and
landline 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 TTY
equipment or 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.
