A method for operating a construction laser in the form of a linear laser or rotating laser having a laser head, by means of a remote controller, which has several input fields (16, 18, 20, 22, 24, 26, 32) for initiating at least one action of the construction laser, wherein the remote control unit contains at least one sensor for determining a change in a parameter of the remote control unit, and the change in the parameter at least influences the at least one action, characterized in that, following activation of the input field (16, 18, 20, 22, 24, 26, 32) assigned to the action, said action is initiated only when the degree of change in the at least one parameter of the remote control unit has at least reached a threshold value, and once the threshold value has been reached, the degree of the at least one action is changed proportionally, dependent upon the degree of change in the parameter, wherein at least one action of the group is carried out: a scan mode, wherein to initiate the scan mode by activating an input field (22, 20) assigned thereto an action is first carried out by means of which a laser beam radiation that can be perceived outside of the rotating laser is carried out over an angle which is dependent on the degree of change in the parameter, rotational speed of the laser head, wherein by activating an input field assigned to the action rotational speed of the laser head and then reaching the threshold value, the speed of the rotating laser head is changed dependent upon the degree of change in the parameter, point mode, wherein to initiate the point mode first the action that determines the rotating speed of the laser head is implemented such that the laser head is stationary, and then by activating the input field (16, 20) assigned to the point mode and reaching the threshold value the rotational position of the laser head is changed dependent upon the degree of change in the parameter, cross-sectional mode, wherein to use the cross-sectional mode, in which an angular region of emitted light which is perceptible from outside the rotating laser is masked, the input field (18, 20) assigned to the cross-sectional mode is activated, and once the threshold value has been reached, the extent of the masked region is changed dependent upon the degree of change in the parameter, tilt of the plane spanned by the rotating laser beam. a scan mode, wherein to initiate the scan mode by activating an input field (22, 20) assigned thereto an action is first carried out by means of which a laser beam radiation that can be perceived outside of the rotating laser is carried out over an angle which is dependent on the degree of change in the parameter, rotational speed of the laser head, wherein by activating an input field assigned to the action rotational speed of the laser head and then reaching the threshold value, the speed of the rotating laser head is changed dependent upon the degree of change in the parameter, point mode, wherein to initiate the point mode first the action that determines the rotating speed of the laser head is implemented such that the laser head is stationary, and then by activating the input field (16, 20) assigned to the point mode and reaching the threshold value the rotational position of the laser head is changed dependent upon the degree of change in the parameter, cross-sectional mode, wherein to use the cross-sectional mode, in which an angular region of emitted light which is perceptible from outside the rotating laser is masked, the input field (18, 20) assigned to the cross-sectional mode is activated, and once the threshold value has been reached, the extent of the masked region is changed dependent upon the degree of change in the parameter, tilt of the plane spanned by the rotating laser beam.
