Maintenance of the trackball remote control

Your trackball on the remote control is very durable and will provide years of use. It has a self-cleaning ball-cage that helps prevent dust and lint built-up around the ball. If the screen cursor jumps or moves abnormally, we recommend that you clean the trackball manually.

To clean your trackball

1.Turn the retainer ring counter-clockwise to remove the ball.

2.Wipe the ball with a clean, lint-free cloth.

3.Blow carefully into the ball cage to dislodge dust and lint.

4.Look for a built-up of dirt on the rubber rollers inside the ball cage. This build-up usually appears as a stripe running around the middle of the roller.

5.If dirty, clean the rollers using a cotton swab moistened lightly with isopropyl (rubbing) alcohol. After cleaning, make sure the rollers are still centered in their channels.

6.Make sure that fluff from the swab is not left on the rollers.

7.Replace the ball and retainer ring.
