manufacturer of your TTY device to ensure that it supports digital
wireless transmission. 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.
