This easy-to-use intercom enables you to talk and be heard automatically with VOX-triggered transmission. In VOX mode, the system will transmit your voice without pressing any buttons. This system is expandable, so with the purchase of additional 900MHz stations, you can customize your own system and talk from any room in your home. No installation or wiring is necessary, simply plug it into a nearby AC outlet or insert 4 "AA" batteries (sold separately). You can even connect a radio, CD player, boombox or other audio device and listen to music from any room on the system.
Includes 2 main units and 2 power adapters.
The product is a re-design of the 43-3102 model. To enhance the intercom function, a VOX circuitry with selectable sensitivity was added such that when the user speaks to the unit, the transmission is turned on automatically.
