About TTY support
When you turn on TTY support and you connect your BlackBerry smartphone to a TTY device that operates at 45.45 bits
per second, you can make calls to and receive calls from TTY devices. Your smartphone is designed to convert received
calls to text that you can read on your TTY device.
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 smartphone. To get an adapter accessory that Research In Motion has approved for use with your
smartphone, visit www.shopblackberry.com.
