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 device 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.
