Guardian angel  is a digital wireless device designed to protect the family. One Base can control up to four Tags. The MAX search range is 500 meters (1600 feet) in line of sight. There are three “Alarm Distance Modes” for each Tag from near, middle or far from the base. Once the tag is out of the set range, both units can trigger an alarm at 95 dB Level. A dis‐alarm function is available to turn‐off alarm function as desired. The tags can be attached to children, pets, cellular phones or any valuable objects. The panic button on the tag can be used to call the base if necessary.
