CW008 LOP (Landing Operation Panel): This panel is located on each floor (landing), outside the elevator doors. Passengers use it to call the elevator, typically with "up" and "down" buttons. The SMG-CW004 would aim to provide a clear, intuitive, and aesthetically pleasing interface for summoning the elevator, possibly featuring updated styling, brighter or more informative indicators for elevator location and direction, and robust construction to withstand public use.
