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

provided with your TTY device, contact your TTY device manufacturer to purchase the
connector cable.
