Wireless Portable Intercom
Overview
Channel Button: Press the Channel 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.
The Intercom has up to a 1000' 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.

On/Off: To turn intercom ON, press any button. To
turn intercom OFF, hold down the Volume button for
5 seconds.
Talk Button: To talk, hold down the Talk button. All
intercoms in the network that are on
the same channel will receive the
Voice Activation Mode (VOX): Voice Activation
signal. Release the Talk button when
done talking and within 10-15 seconds
press and hold the Talk button of a
different intercom to make a secure
channel between the two. Once the
channel is made the other intercoms in
the network cannot hear the conversation.
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.

Troubleshooting
Intercom does not function.
Check batteries in intercom. If using an AC Adapter
ensure that it is plugged in.
Ensure intercom is connected to a network.
See Programming Intercom.
Ensure that intercoms are on the same channel. See
Operation & Features.
Need to clear intercom’s memory.
Press and hold Learn button, an initial beep will be
heard. Continue to hold until a second beep is heard
(about 15 seconds). Ensure other intercoms are not
activated during this time. Intercoms in the network that
are on will signal during the clearing process. Once
memory is clear the intercom can be programmed to a
new network.
Intercom is not getting expected transmission
range.
Keep antenna vertical. Keep intercom away from
trees, metal objects and electrical wiring. Cell phones,
cordless phones, or other radio devices may also
limit range.
Static and feedback is heard in intercom.
The intercoms are too close to each other. A cordless
phone, cell phone, or other radio devices can also
cause static.
Intercom is sending audio while no buttons are
pressed.
Intercom beeps every ten minutes.
The battery is low in the intercom. Replace with AA
Alkaline batteries or operate it with AC Adapter (not
provided). A 9-12 volt, 500mA AC Adapter may be
used (center positive polarity on the round plug).
The sending intercom is set to Monitoring Mode or Voice
Activation Mode and will activate when sound is heard.
It can be taken out of Monitoring Mode by pressing the
Talk button. It can be taken out of Voice Activation Mode
by setting Dipswitch #1 to DOWN position.
