MAINTENANCE OF YOUR 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.
