\ QUIET TALK (QT) AND DIGITAL QUIET TALK (DQT) j
QT and DOQT are functions to reject signals from undesired
persons that are using the same channel. A QT tone or
DQT code is programmed in each of the 4 channels at the
factory, as code 1 in ch. 1, code 10 in ch. 2, code 19in
ch. 3, and code 28 in ch. 4. After selecting one of those
channels, you will hear audio from the speaker only when
you receive a signal that contains the matched code.
