Abstract:
Screen display apparatus capable of generating a display signal of a physical parameter, with the display signala) consisting of a numerical display value and/or b) a number of symbols, â€ƒwhile aa) the shown numerical display value is approximately proportional to the level and/or the number of the adjusted increments of the adjusted value that is allocated to the signal, or bb) the number of the symbols is approximately proportional to the level and/or the number of the adjusted increments of the adjusted value that is allocated to the signal, wherein the adjusted value of an operational parameter is allocated a symbol of a certain color and/or a symbol of a certain shape, and the color symbols and/or shape symbols for adjoining symbols or symbol groups of sequential adjusted values of operational parameters differ from each other, and wherein, at a normal range of an operational parameter, e.g. at room volume level, the interval size or the incremental increase is smaller than at the maximum range, and/or the different interval sizes or the different incremental increases can be displayed with the allocated symbol itself, i.e. based on position, size, color or shape, and wherein the color and/or shape design of a particular symbol and/or numerical display for a preferred parameter setting can be chosen by the user, and can be saved into a memory, and wherein the device incorporates the means to adjust several operational parameters, consisting of a one-piece servo component which can be pushed in and/or turned in several directions; with a first movement of the one-piece servo component, the adjustment mode of an operational parameter can be called up, and with another movement of the servo component the value adjustment of the called up operational parameter can be implemented.
