To ensure stability, the lid must be firmly seated in the tray. In some cases, the lid becomes ragged. In this case, alternating movements must be used.
Hold the shell of the ALLDOCk with one hand. Now grasp the docking rail very far out on the side. Lift the lid of the ALLDOCK by alternately pulling it up from the left and right. Do not try to grip the lid in the middle, this will not work.
Usually it is enough to lift the lid on one side for 1 mm. This will solve the problem.
