TTY Use With Handset
A TTY (also known as a TDD or Text Telephone), is a telecommunications device
that allows people who are deaf, hard of hearing, or 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 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.

IMPORTANT 911 Emergency Calling:
We recommend 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 TTY equipment or software used by PSAPs. This matter has been
brought to the attention of the FCC, and the wireless industry and PSAP community
are currently working to resolve it.
