TTY Mode
A TTY (teletypewriter, also known as a TDD or Text Telephone) is a telecommunications phone
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 phones. Please check with the manufacturer of your
TTY phone to ensure that it supports digital wireless transmission. Your phone and TTY phone
will connect using a special cable that plugs into your phone’s headset jack. If this cable was not
provided with your TTY phone, contact your TTY phone manufacturer to purchase the
connector cable.
