Maintenance
Early malfunctions can be prevented. Careful and regular cleaning can extend the lifetime of your TV. Be
sure to turn the power off and unplug the power cord before you begin any cleaning.
• Do not use your TV in areas that are too hot or too cold, because the cabinet may warp or the screen
may malfunction. Your TV works best in temperatures that are comfortable to you.
• Storage temperatures are 0˚ to 50˚C (32˚ to 122˚F)
• Working temperatures are 0˚ to 35˚C (32˚ to 95˚F)
• Do not place your TV in direct sunlight or near a heat source
• Minimum 5cm clearance around device for sufficient ventilation
• Do not cover ventilation openings with items such as newspapers, tablecloths, curtains, etc.
• No open flames should be placed on or near the apparatus (such as candles)
Cleaning the screen
1. Wet a soft cloth in a mixture of lukewarm water and a little fabric softener or dish washing detergent.
Wring the cloth until it’s almost dry, and use to wipe the screen.
2. Make sure the excess water is off the screen, let air-dry before you turn on the TV.
Cleaning the Cabinet
To remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth. Please be sure not to use a wet
cloth.
Extended Absence
If you expect to leave your TV dormant for a long time (such as a vacation), it is a good
idea to unplug the power cord to protect against possible damages from lightning or
power surges.
