Using TTY
A TTY (also known as TDD or Text Telephone) is a
telecommunications device that allows people who are deaf or hard
of hearing, or who have speech or language disabilities, to
communicate by telephone.
Your Treo 600 is compatible with select TTY devices. You can
connect a TTY/TDD machine to your phone through the headset
jack, but you cannot use your headset jack with a headset or hands-
free kit while this mode is enabled. Please check with the
manufacturer of your TTY device for connectivity information and to
ensure that the TTY device supports digital wireless transmission.
To use TTY, you may need to make additional arrangements with
your wireless service provider. Please contact their customer service
department for more information.
