This product has been designed and manufactured in the USA, utilizing the highest quality standards available. Model 06/16/05 Patents pending With the Lifestyle Wirefree Intercom, you can talk up to 1000 feet, completely wire free with a 900 MHz secure digital radio link. For privacy, your intercoms form an exclusive network, and respond only to other intercoms in your network. (Patent Pending) Even conversations within your network are secure, as intercoms automatically pair up, blocking all other intercoms from listening in. Additional features include: hands-free operation, baby monitoring with adjustable sensitivity, and non-secure conferencing mode. Please read the instructions carefully. TM INTERCOM QUICK SETUP GUIDE 1) Remove the battery door fr om 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 In tercoms 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. Using the Intercom 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. Channel Selection 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. Adjusting the speaker volume Press the VOLUME button up or down to adjust loudness of unit. Turning the intercom On or Off An intercom may be turned off by holding down the VOLUME button down for five seconds. To turn it back on, press any button. Volume Active/ Monitor Power Light Channel Power Monitoring Mode (Patent Pending) 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. Voice Activation Mode (VOX) 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). Note: the caller may interrupt you at any time by pressing TALK on their intercom. Conference Mode 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. Batteries 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. Troubleshooting and Frequently Asked Questions My intercom does nothin g. What should I do? 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 communic ate, 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. How do I Remove an Intercom from a Network? 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. Why is the intercom not getting the expected 1000 foot range? To assure best range, make sure that the intercom unit’s antenna is VERTICAL. Cell phones, cordless phones, or other radio de…
