moisten the soft cloth with a mild or neutral detergent and then wipe off any
stains.

completely air-dry.
îš„ Cleaning the trackball
(1) Disassembling the trackball
Press the bulges on the clamping ring by both hands and turn the ring about 45°
clockwise until it lifts. Take out the ring and the rotary ball. Be careful not to drop
the ball.
(2) Cleaning the trackball mechanism and rotary ball
There can be a considerable buildup of finger oils and dirt on the internal trackball
mechanisms. Use a cotton swab or soft dry cloth to clean the two long shafts and
rotary bearing and to remove any accumulation.
Use the soft dry cloth to clean the rotary ball.
(3) Installing the trackball
Put the rotary ball back in the trackball mechanism and align the clamping ring
with the top cover notches. Press the bulges on the ring with both hands and turn
the ring about 45° counterclockwise until the ring clicks and locks. As the bulges
are flush with the top cover, the ring is secured.
