Wireless Flush Mount 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.

Troubleshooting
Need to clear intercom’s memory.
Intercom does not function.
Press and hold both buttons. Two beeps will be heard
and the channel lights will begin to cycle. Continue to
hold until a third 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.
It is normal for LEDs to go out if intercom has been
inactive for 5 minutes. The LEDs should light after a
button is pressed or a signal is received.
Check batteries in Intercom.
Ensure intercom is connected to a network.
See Programming Intercom.
Ensure that intercoms are on the same channel. See
Operation & Features.
Static and feedback is heard in intercom.
The intercoms are too close to each other. A cordless
phone, cell phone, or other radio device can also
cause static.

range.
Keep Intercom away from trees, metal objects and
electrical wiring.
Intercom beeps every ten minutes.
The battery is low in the intercom. Replace with
