The NC570 Receiver enables communication between transmitters and the Tek-CARE Appliance Server in a Tek-CARE 570 Wireless Nurse Call System. The NC570 Receiver collects wireless transmissions from NC571 Repeaters placed strategically throughout the facility. This information is then provided to the NC475DESK annunciator for visual and audible on the system. The RJ10 (4P4C) to serial cable is provided to connect the NC570 to the NC475DESK.
