SAFETY INSTRUCTIONS
Use only with the cart, stand, tripod, bracket,
or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use
caution when moving the cart/apparatus
combination to avoid injury from tip-over.
Never touch this apparatus or antenna during
a thunder or lighting storm.
Do not allow a impact shock or any objects to
fall into the product, and do not drop onto the

been damaged in any way, such as power-supply
cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus,
the apparatus has exposed to rain or moisture,
does not operate normally, or has been
dropped.
CAUTION concerning the Power Cord :
Most appliances recommend they be placed
upon a dedicated circuit; that is, a single outlet
circuit which powers only that appliance and
has no additional outlets or branch circuits.
Check the specification page of this owner's
manual to be certain.
Do not overload wall outlets. Overloaded wall
outlets, loose or damaged wall outlets, extension
cords, frayed power cords, or damaged or
cracked wire insulation are dangerous. Any of
these conditions could result in electric shock
or fire. Periodically examine the cord of your
appliance, and if its appearance indicates damage or deterioration, unplug it, discontinue use
of the appliance, and have the cord replaced
with an exact replacement part by an authorized
servicer. Protect the power cord from physical
or mechanical abuse, such as being twisted,
kinked, pinched, closed in a door, or walked
upon. Pay particular attention to plugs, wall
outlets, and the point where the cord exits the
appliance.

Early malfunctions can be prevented. Careful and regular cleaning can extend the amount of time you can
enjoy your new TV.
Caution: 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 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 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
GG
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.
