The home theater entertainment experience is a growing trend, and larger TVs are popular
purchases. However, TVs are not always supported on the proper stands or installed
according to the manufacturer’s recommendations. We and the consumer electronics
industry are committed to making home entertainment enjoyable and safe.
TVs that are inappropriately placed on dressers, bookcases, shelves, desks, speakers, chests, or
carts may fall over and cause injury.
Tune into safety
•One size of TV stand does not fit all. Use only a TV stand
rated for the weight of your TV.
•Carefully read and understand all enclosed instructions
for proper use of this product.
•Don’t let children climb on or play with entertainment
system furniture and TVs.
•Don’t place TVs on furniture that can easily be used as
steps, such as a crate or chest of drawers.
•Remember that children can become excited while
watching a program, especially on a “larger-than-life” TV.
Make sure that you place or install the TV where it cannot
be pushed, pulled over, or knocked down.
•Make sure that you route all cords and cables so that they
cannot be pulled or grabbed by curious children.

Wall mounting
If you decide to wall mount your TV, always remember:
•One size of wall mount does not fit all. Use only a wall mount rated for the weight of
your TV and that has been recommended by this TV manufacturer, listed in this
manual, or otherwise listed by an independent laboratory as suitable for your TV.
•Follow all instructions supplied by the TV and wall mount manufacturers.
•If you have any doubts about your ability to safely wall mount your TV, get help from a
professional installer.
•Make sure that the wall where you are mounting the TV is
appropriate. Some wall mounts are not designed to be
mounted to walls backed with steel studs or cinder blocks. If
you are unsure, ask a professional installer.
•TVs can be heavy. At least two people are required for safe wall mount installation.

moisture. No user-serviceable parts are inside. Refer
servicing to qualified service technicians.
Lightning
For added protection for your device receiver
during a lightning storm, or when it is left
unattended and unused for long periods of time,
unplug it from the power outlet and disconnect any
antenna or cable system. This helps prevent
property damage and personal injury from
lightning and power line surges.
Power lines
An outside antenna system should not be located in
the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall
into such power lines or circuits. When installing an
outside antenna system, extreme care should be
taken to keep from touching such power lines or
circuits as contact with them might be fatal.

Article 820 of the National Electrical Code,
ANSI/NFPA No. 40 provides guidance for correct
grounding. Specifically, it states that the cable
ground must be connected to the grounding
system of the building as close to the point of cable
entry as practical.
Condensation
Moisture will form on the TV if the TV is brought
from cool surroundings into a warm room or if the
temperature of the room rises suddenly. When this
happens, the TV's performance may be impaired. To
prevent this, let the TV stand in its new
surroundings for about an hour before switching it
on, or make sure that the room temperature rises
gradually.
Condensation may also form during the summer if
the TV is exposed to the breeze from an air
conditioner. In such cases, change the location of
the TV.
Mobile telephone warning
To avoid interference with your TV picture and
sound, operating problems, or even damage, keep
your cordless and cellular telephones away from
