b) Cleaning:
Clean the two long shafts, the bearing, plastic cover and the internal area of clamping ring (see

Put the trackball into that. The long axis of clamping ring aims at the slot of trackball’s cover. Press
the bulges of the clamping ring with fingers. Rotate the ring 35 degrees clockwise to lock it. The
ring is installed well if the position of two bulges on the ring is perpendicular to device’s panel. See
