摘要： An electrically and manually adjustable screening device for screening a window. The screening device has a screen with a variable length and a positionable free end. The longitudinal position of the free end determines the length of the screen. An electric drive is operably connected to the screen for adjusting the longitudinal position of said free end. A sensor arrangement is configured to detect manual movement of the longitudinal position of the free end and for outputting a detection signal. A circuit or processor is configured to control the speed of the electric drive and is configured to ramp up the speed of the electric drive in response to a detected manual movement starting the ramp up at a speed similar to the speed of the detected movement to gradually take over from the manual movement.
