Enable TTY/TDD
A TTY (also known as TDD or text telephone) is a telecommunications
device that allows people who are deaf or hard of hearing, or who have
speech or language disabilities, to communicate by telephone. Your phone
is compatible with select TTY devices.
Not all wireless service providers support the TTY feature on your phone.
Check with AT&T for information.
You can connect a TTY/TDD machine to your phone using the headset
jack. Check with the manufacturer of your TTY device for connectivity
information. Be sure that the TTY device supports digital wireless
transmission.
NOTE
When TTY is enabled, you cannot use the headset jack for anything else,
and all audio modes are disabled on your phone, including holding the phone up to
your ear and listening.
