1. Check your phone line.
Pick up the receiver of a telephone connected to
a line that the TDD Detector is monitoring.
Listen to the dial tone on the line. It should
sound clear and loud.
2. Press the black "RESET" button on the
front panel.
3. Press the red "SEND" button.
You will hear a series of beeping sounds on the
phone line. The beeping sounds you hear are
the sounds of the TTY message (in Baudot code)
being sent over the line by the TDD Detector.
The message says, "TYPE YOUR NAME GA."

the TTY message, "911 HERE PLEASE
HOLD." All the lights on the front panel of
the TDD Detector should come on, and
the receive circuitry in the unit is
