TTY Mode
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.
