MAINTENANCE
Careful and regular cleaning can extend the amount of time you can enjoy your new set. 
Caution: Be sure to turn the power off and unplug the power cord before you begin any cleaning.
Cleaning the Screen
To keep the dust off your screen for a while, wet a soft cloth in a mixture of lukewarm water and a little fab-
ric softener or dishwashing detergent. Wring the cloth until it’s almost dry, and then use it to wipe the
screen.
Make sure the excess water is off the screen, and then let it air-dry before you turn on your set.
Cleaning the Cabinet
ATo remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth.
APlease be sure not to use a wet cloth.
Extended Absence
GIf you expect to leave your set dormant for a long time (such as a vacation), it’s a good idea to unplug
the power cord to protect against possible damage from lightning or power surges.
