Advanced features include detection of both analog and digital cell phones, alarming upon Standby mode signals (when a cell phone is ON but a call is not in progress), and a remote alarm output for connection to an external device such as an annunciator panel or alarm system. Hidden, front-accessible controls and external input/output jacks make it easy to adjust the CellPhone Detector Plus for a specific coverage area, detection method, or alarm mode. Advanced features include detection of both analog and digital cell phones.
