Trackball Cleaning Procedures

1. Turn off the computer, disconnect AC power, and remove the battery

pack.

2. Remove the optical trackball.

3. Remove any large particles of debris that have fallen into the

trackball housing.

4. Dip a cotton swab in isopropyl alcohol and squeeze off excess liquid.

5. Carefully wipe inside the cage to remove residue from surfaces. Clean

the ball bearings by rubbing with the swab. Do not attempt to remove the

bearings. DO NOT USE ALCOHOL ON THE SENSOR WINDOW. Instead, gently wipe

the sensor window with a soft, dry, lint-free cloth until all debris is

removed. Allow enough time for the parts to air dry before reassembling.

6. Replace the ball and gently secure the retaining ring by rotating it

clockwise.
