It features 3 volume settings and alarm tones, two alarm settings and two distance settings. It is easy to align, with LED indicator lights on both units and emits a low battery warning signal.
Each unit uses 1 x 9v battery or can be used with a mains adapter (neither batteries or mains adapter included).
