Overview
The Intercom has up to a 1000 foot (300 m) range and
allows multiple simultaneous conversations, using a
900 MHz secure digital radio link. The intercoms
form an exclusive network and respond only to other
intercoms in the network.
Carton Inventory

Operation & Features
Channel Select Button: Press
the Channel Select button to set
intercom to one of four secure
channels or the paging channel.
The default channel for the intercom
is the paging channel where all four
channel lights are lit. An intercom
on a channel can only hear an
intercom on the same channel or on
the paging channel.
Battery: The AA Alkaline batteries
(not provided) will last up to a year
depending on use. When batteries
are low intercom will emit three
beeps every ten minutes.
A DC Adapter (not provided) can
also be used to power the intercom.
In this case, the channel lights will
remain on.
Conference Mode: Conference Mode allows multiple
intercoms to participate in a conversation compared
to Normal Mode in which only two intercoms
can communicate. All intercoms must be set
to the same channel or the paging channel
to be in Conference Mode. To put intercom
in Conference Mode set Dipswitch #2 to UP
position.
Monitor Mode: Monitor Mode
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
listen to that room. If a specifi c channel is selected
for Monitor Mode then only other intercoms on that
channel or on the paging channel can listen. Press the
Talk button to exit Monitor Mode. A tone will be heard
indicating Monitor Mode is no longer active.
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 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.
