Troubleshooting  
Intercom does not function.  
Need to clear intercom’s memory.  
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.  
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.
