APPENDIX
MAINTENANCE
Early malfunctions can be prevented. Careful and regular cleaning can prolong the life of your new TV.
Caution: Be sure to switch the power off and unplug the power cord before you begin any cleaning.
Cleaning the Screen
A good way to keep the dust off your screen for a while is to wet a soft cloth in a mixture of lukewarm water
and a little fabric softener or dish washing detergent. Wring the cloth until it is almost dry, and then use it
to wipe the screen.
Ensure there is no excess water on the screen. Allow any water or dampness to evaporate before switching on.
Cleaning the Cabinet
ATo remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth.
ADo not to use a wet cloth.
Extended Absence
GIf you expect to leave your TV dormant for prolonged periods (such as a holiday), unplug the power
cord to protect against possible damage from lightning or power surges.
