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,

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.
1. Touch TTY mode.
2. Touch TTY Full, TTY HCO, or TTY VCO.
A green circle displays next to your selection.
