is used to monitor the noise in a
specifi c room. Place the intercom
in the room that is to be monitored
and press the Monitor button until
a tone is heard. For extended
Monitor usage, consider using a
plug-in transformer. Any other networked intercom can

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 fi rst 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.
