y Outdoor Antenna Grounding  
(Can differ by country):  
y CAUTION concerning the Power Cord  
(Can differ by country):  
Check the specification page of this owner’s  
manual to be certain. Do not connect too many  
appliances to the same AC power outlet as this  
could result in fire or electric shock. 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 service. 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. Do not move the TV with the  
power cord plugged in. Do not use a damaged or  
loose power cord. Be sure do grasp the plug when  
unplugging the power cord. Do not pull on the  
power cord to unplug the TV.  
If an outdoor antenna is installed, follow the  
precautions below. An outdoor antenna system  
should not be located in the vicinity of overhead  
power lines or other electric light or power  
circuits, or where it can come in contact with  
such power lines or circuits as death or serious  
injury can occur. Be sure the antenna system is  
grounded to provide some protection against  
voltage surges and built-up static charges. Section  
810 of the National Electrical Code (NEC) in the  
U.S.A. provides information with respect to proper  
grounding of the mast and supporting structure,  
grounding of the lead-in wire to an antenna  
discharge unit, size of grounding conductors,  
location of antenna discharge unit, connection to  
grounding electrodes and requirements for the  
grounding electrode.

CHILD SAFETY:  
PROPER TELEVISION PLACEMENT MATTERS  
THE CONSUMER ELECTRONICS INDUSTRY CARES  
• Manufacturers, retailers and the rest of the consumer electronics industry are committed to  
making home entertainment safe and enjoyable.  
• As you enjoy your television, please note that all televisions – new and old- must be supported on  
proper stands or installed according to the manufacturer’s recommendations. Televisions that  
are inappropriately situated on dressers, bookcases, shelves, desks, speakers, chests, carts, etc.,  
may fall over, resulting in injury.  
TUNE IN TO SAFETY  
ALWAYS follow the manufacturer’s recommendations for the safe installation of your television.  
ALWAYS read and follow all instructions for proper use of your television.  
NEVER allow children to climb on or play on the television or the furniture on which the television  
is placed.  
NEVER place the television on furniture that can easily be used as steps, such as a chest of  
drawers.  
ALWAYS install the television where it cannot be pushed, pulled over or knocked down.  
ALWAYS route cords and cables connected to the television so that they cannot be tripped  
over, pulled or grabbed.  
WALL OR CEILING MOUNTYOUR TELEVISION  
ALWAYS contact your retailer about professional installation if you have any doubts about your  
ability to safely mount your television.  
ALWAYS use a mount that has been recommended by the television manufacturer and has a  
safety certification by an independent laboratory (such as UL, CSA, ETL).  
ALWAYS follow all instructions supplied by the television and mount manufacturers.  
ALWAYS make sure that the wall or ceiling where you are mounting the television is appropriate.  
Some mounts are not designed to be mounted to walls and ceilings with steel studs or cinder  
block construction. If you are unsure, contact a professional installer.  
Televisions can be heavy. A minimum of two people is required for a wall or ceiling mount  
installation.  
MOVING AN OLDER TELEVISION TO A NEW PLACE IN  
YOUR HOME  
• Many new television buyers move their older CRT televisions into a secondary room after the  
purchase of a flat-panel television. Special care should be made in the placement of older CRT  
televisions.  
ALWAYS place your older CRT television on furniture that is sturdy and appropriate for its size  
and weight.  
NEVER place your older CRT television on a dresser where children may be tempted to use the  
drawers to climb.  
ALWAYS make sure your older CRT television does not hang over the edge of your furniture.
