Uniphone 1150 Using Instruction page 2

Acknowledgement
In 1963, Dr. Robert H. Weitbrecht, an
American physicist who was deaf, developed
an acoustic coupler that could send and
receive teletypewriter signals over the
telephone lines. His invention, the
Weitbrecht Modem, enabled people who
are deaf to use the telephone for the first
time.
While modern technology now makes it
possible to build advanced microcomputer
devices like your new Ultratec text
telephone, the Weitbrecht modem remains
the major technological break-through that
began telecommunications for the deaf. Ultratec wishes to
acknowledge the importance of Dr. Weitbrecht's contribution to
the welfare of people who are deaf the world over.
