EXTENDED ABSENCE
If you leave your Entertainment Machine dormant for a long time (such as a vacation), it’s a good

an off-air antenna, you may also want to disconnect it from the back of your Entertainment Machine
before leaving.

PICTURE INTERFERENCE
Even though you may be getting cable, the signal may be weak, which means the quality of your

VIDEO GAMES AND OTHER FIXED-PATTERN DISPLAYS
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 or using
the Game preset.

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.
