The
manual reset installation
for the TDD
Detector requires no special wiring. However,
with this installation, your operator is
responsible for pressing the "RESET" button at
the end of each TTY call he or she receives.
When the "RESET" button is pressed, the TDD
Detector resumes monitoring the phone line for
TTY signals.
If the operator fails to press the "RESET"
button, the TDD Detector will reset itself after a
standard 10-minute time-out period.
Turn to page 4 for manual reset installation
instructions.
NOTE: The length of the time-out period can be
changed at Ultratec to meet your specifications.

The manual reset installation
requires no specific
adjustments to your
telephone equipment.
In the
automatic reset installation
, the TDD
Detector determines the beginning of each new
telephone call by detecting loop current, or by
monitoring the on- or off-hook status of the
phone line. In either case, the TDD Detector
knows when an operator has answered a call,
and automatically monitors the beginning of
that call to listen for TTY signals. When the
operator hangs up, the TDD Detector will wait
until the beginning of the next incoming call to
monitor the phone line. The operator does not
need to press the "RESET" button.
Turn to page 5 for automatic reset installation
instructions.
In the automatic reset
installation the TDD Detector
monitors the
on-hook or off-hook status of
the phone line.
