TTY or TELETYPE Support

The TTY or teletype is a common name for the telecommunications device for the deaf
(TDD). Your BlackBerry is designed so that it can convert received calls into text that
can be read on a TTY device. You need to connect your BlackBerry to the TTY device
and then enable that option.
Make sure your wireless carrier supports TTY (most do). Start the phone call logs with
the Green Phone key if you are not already in the Phone app. Then press the Menu key
and select Options. Select TTY to see the screen and make sure that TTY Mode is set
to Yes. Save your changes.
Make sure that the TTY device operates at the universal standard of 45.45 BPS.
Connect the TTY device to the Headset Jack on the BlackBerry. (There are other
adapters, but this is the easiest way to connect the BlackBerry to a TTY device.)
