The Pocket Radar technology is specifically designed to be very safe to use. The patented new sensor technology is designed to work with a very low power. It operates using simple radio waves like all wireless communications. The output power is much less than almost all commonly used wireless devices. Our Radars operate on the license-free ISM band from 24,075 to 24,175 MHz. The nominal radio frequency power from the Pocket Radar is about 2.5 mW, while a cell phone can put out over 1000 mW. The maximum radio wave exposure possible from a Pocket Radar is more than 1000 times lower than the FCC standard for maximum continuous exposure to this kind of radio wave emission. The radio wave energy exposure when using a Pocket Radar is many, many times lower than a person gets from using a cordless telephone or carrying a cell phone. It is also less exposure than you can get from wearing a wireless headset or earbuds, or from standing beside an operating microwave oven.
