CordLess Monitor (sold separately) and sensor pads use wireless technology, eliminating the need for cords and allowing you to place the monitor wherever it's most convenient, even outside the resident room. The monitor can support two sensor pads (bed and bed, bed and floor mat, floor mat and chair, floor mat and floor mat, bed and chair) at once. The pad-lost feature operates with four-minute delay. Bed pad is placed under the resident on the bed.
