INTERCOM QUICK SETUP GUIDE 

 

1)  Remove the battery door from the bottom of each unit and place four fresh AA 

Alkaline batteries in the battery pack. The batteries are installed, the channel 

lights will begin to flash in sequence.   

 

2)  To create an Intercom Network, stand the antennas up, then Press the LEARN 

button for 1 second on each intercom.  Note: LEARN buttons must be pressed 
within ten seconds of each other on the first two units. The units will beep as 
they join the Network.  Additional Intercoms may be added to the network at 
any time by pressing the LEARN button on one of the networked units and on 
the new unit.  

 

3)   Press and release the TALK button on an Intercom unit to verify that the 

network is complete. 

To talk, hold down the TALK button.  All 
intercom units in your network will receive 
the signal. When somebody responds by 

holding down the TALK button on a different 
intercom unit, a secure channel is created 
and other units will not hear the signal, 
making your conversation secure.  

 

The default setting for the intercom is 

Paging Mode, with all four Channel lights 
flashing in sequence). Pressing the CHANNEL 

button will set an intercom unit to one of four 
secure channels.  While on a channel, you can 
only be heard by other units set to the same 
channel or in paging mode.  

 

Press the VOLUME button up or down to 
adjust loudness of unit. 

 

An intercom may be turned off by holding 
down the VOLUME button down for five 
seconds. To turn it back on, press any button.

Press monitor to place the intercom in 
monitor mode, making it voice activated.  
To adjust sensitivity, press the VOLUME 

button to cycle through the three 
sensitivity settings, with three beeps 
being the most sensitive.  

 

To talk to this unit from another 
intercom on the same channel, press the 
TALK button, even while hearing audio 

from the unit in monitoring mode.  

 

When in VOX mode, you may answer a 

call by simply speaking loudly.  After a 
brief delay, your intercom will begin to 
send audio, and will wait for you to finish 
speaking.  
To place the unit in VOX mode, slide 

dipswitch #1, UP (by the LEARN button).  

 the caller may interrupt you at 

any time by pressing TALK on 
their intercom. 

 

     

To put an intercom unit in Conference 
mode, slide dipswitch #2 UP.  This will 
allow any number of units to join a 
conversation, not just two. 

With average use, the batteries will last 
up to one year, or four months in 
monitoring mode. A double beep every 

ten minutes will alert you that the 
batteries are getting low. If desired, the 
Intercom may also be powered by a 12-
volt DC transformer (commonly 
available) in most department stores). In 

this case, both the power and channel 
lights will remain on constantly.

If there are no lights illuminated, make sure four fresh AA alkaline batteries are all 
installed correctly.  The CHANNEL lights should flash.   If you are using the optional 
12-volt transformer, make sure it is plugged in.  The POWER and CHANNEL lights 
should be continuously on.  If not, try another outlet.  
If the units have power but do not communicate, they may need to form a network. 
Press the LEARN button on each unit that needs to form a network and they will beep 
in response.  You may need to clear their memory and re-teach them (see Removing 
from a Network, below).  
If the units do not have the same channel light flashing, press the CHANNEL button 
until both units are on the same channel or in Paging mode, with all channel lights 
illuminated.  

 

Press and hold the Learn button, for fifteen seconds. It will beep when it has 
cleared its memory and you can re-teach it to a new intercom. If an intercom signals, 
while the Learn button is depressed, the procedure will have to be repeated.  

To assure best range, make sure that the intercom unit’s antenna is VERTICAL.  Cell 
phones, cordless phones, or other radio devices may reduce the intercom’s range if 
they are within a few feet of an intercom. Trees, metal, electrical wiring or other 
electrical devices directly between units may also limit the range.   

 

The sending intercom is set to Monitoring Mode or Voice Activated mode and will 
activate when it hears something. Pressing the VOLUME button can set the 
sensitivity of the microphone. It can be taken out of Monitoring Mode by pressing 
the TALK button, or taken out of VOX mode by pushing Dipswitch #1 down.   

 

The intercom is indicating that the batteries are low and need to be replaced.  

 

The intercom is probably too close to another intercom. Once the intercom is 
installed in the desired location, it will operate normally. If a cordless phone, cell 
phone, or other radio device is too close to the intercom and can limit the range.   

 

The Wirefree intercom is optimized for high quality AA batteries, but it may be 
powered by an 9-12 volt, 500mA, DC transformer purchased separately (center-
positive polarity on the round plug) like Radio Shack’s 

.
