cleaning can extend the amount of time you will have
your new TV. Be sure to turn the power off and unplug
the power cord before you begin any cleaning.
Cleaning the Screen
Here’s a great way to keep the dust off your screen A
for a while. 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
then use it to wipe the screen.
Make sure the excess water is off the screen, and B
then let it air-dry before you turn on your 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’s a good idea to unplug the power
cord to protect against possible damage from lightning
or power surges.

Note
Production of the screen requires high and precision R
technologies. However, there might be some
dank or bright (red, blue or green) spots, or some
anomalistic stripes or spots. This is not defect. If the
TV set is used in an area 2,400 meters above the sea
level where the air pressure is below 750hpa, the
picture on the screen maybe affected and a muffled
sound might be produced. These phenomena
might happen in the area 1,500 meters above the
sea level. This is resulted from difference between
air pressures inside and outside the display. This is
not a defect covered by the limited warranty.
