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.  
Intercom is not getting expected transmission  
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  
C batteries.  
NOTE: To prevent damage to the circuit DO NOT use  
C size Lithium batteries.
