Specifications

Although it is connected to your phone line, the
TDD Detector does not affect the normal
operation of your telephone equipment.
NOTE: If your installation requires a TTY
message that differs from the standard message
("911 HERE PLEASE HOLD"), you can order a
custom message for your TDD Detector. See
page 11.

Your operators control the TDD Detector by
pressing the "RESET" or "SEND" buttons on the
front panel. These same operations can be
accomplished by easy-to-use commands from
the operator's Touch-Tone® telephone.
Additional Touch-Tone® commands allow your
operators to abort (stop) the send command,
and to test the TDD Detector's internal circuits.

There are two ways to install the TDD Detector
in your setting—the manual reset installation
and the automatic reset installation.
The manual reset installation requires no
special wiring, but your operators should be
trained to reset the Detector after it has
received a TTY call. The automatic reset
installation requires that your TDD Detector be
installed so that it can detect the on- and off-
hook status of the phone line. It will
automatically reset when the operator hangs up
after a TTY call.
Refer to page 3 for a complete description of the
two installations.
