But in the spirit of exploration I had a go nevertheless at the remote control on the wall. On the top row, from left to right: the Off button, a directed spray to the bum, a broad spray, the female option (I was too afraid to try), and the air dryer. Vertically on the lower panel: the control turning on a pulsating flow, a vertically oscillating flow, then two buttons controlling the strength of the flow, and finally two buttons controlling the position of the jet. The most advanced toilet I encountered also had a button that simulated the sound of flushing, to cover up any embarassing sounds you might be producing.
