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 headset jack. If this cable was not
provided with your TTY device, contact your TTY device manufacturer to purchase the connector
cable.

Warning
:
9-1-1 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 9-1-1 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.
