Voice Activation Mode (VOX):
Voice Activation Mode (VOX)
allows a call to be answered
without pressing the Talk button.
Once a call is heard on an intercom
which has been set to VOX, a response can be given by
speaking loudly into the intercom. There will be a slight delay
when VOX is first activated by a voice, but will continue to
transmit audio until the speaking stops. To put intercom into
VOX, place Dipswitch #1 to the UP position. While in VOX
mode, a call may be initiated by pressing the Talk button.
