Turn on TTY support
TTY support is designed to allow your device to connect with an external TTY device that converts received calls to text.
The TTY device that you want to connect to your BlackBerry device must operate at 45.45 bps. If your TTY device is
designed for use with a 2.5-mm headset jack, you must use an adapter accessory to connect your TTY device to your
device. The adapter end that plugs into the TTY device must be a male three pole mono 2.5-mm headset jack, and the end
that plugs into your BlackBerry device must be a male four pole stereo 3.5-mm headset jack.
