A method for setting at least one parameter on an actuation element (1) for triggering a function, in particular flushing, on a sanitary system, wherein the actuation element (1) comprises at least two actuation sensors (2, 3) for detecting an input of a user and at least two optical display elements (4, 5). The actuation element (1) is transferred from an operating mode (B) into a setting mode (E), in which said parameters can be set, with the simultaneous activation of at least two actuation sensors (2, 3) over a preset time interval (T1).
