The device comprises first markers (16, 24, 202) which either are arranged on the axis of a gun (2, 20, 200) or project radially, reflectors (15, 201) or a projector which either are arranged on the axis of the gun or project from the axis in the same direction as the markers or opposite to these, and a control apparatus (8, 10) with a control circuit for controlling the guns (2, 20, 200), which contains a circuit which can be cut off and can be controlled separately. For the basic setting, the guns (2, 20, 200) are adjusted via the control apparatus (8, 10) on the observation unit (1) in such a way that, after the basic setting, the first markers point in a direction directly towards or away from the observation unit (1). By means of the device, a person at the observation unit (1) can carry out the basic setting of the guns in a simple and easily read-off way. <IMAGE> |
