Even though you may be getting cable, the signal may be weak, which means the quality
of your picture may suffer due to other factors. If there are problems with the image on your
Entertainment Machine, consult the Troubleshooting guide on the following pages.
If you use your Entertainment Machine to play video games or for other uses that have single,
fixed images, such as a photo-CD player, you should avoid setting the Brightness level too high.
If static images, like network identification patterns, are left sitting for too long, they can leave
a permanent impression on the picture tube. You can reduce the chance of this happening by
limiting the amount of time you use the fixed-image display, and by reducing the contrast and
brightness levels.
Sometimes the Trakball gets greasy or dirty, which can affect it’s performance. To clean it, moisten
a cloth with a solution of dish washing detergent and water. Gently wipe the exposed area of the
Trakball, rolling it with your thumb. Allow the remote to dry before using it again.
NOTE: Do NOT use alcohol or other “cleaning fluids” anywhere on the remote control.
