Congratulations on your purchase! As you enjoy
your new TV, keep these safety tips in mind:
The Issue
¾
If you are like most consumers, you have a TV in your home.
Many homes, in fact, have more than one TV.
The home theater entertainment experience is a growing
¾
trend, and larger TVs are popular purchases; however, they
are not always supported on the proper TV stands.
Sometimes TVs are improperly secured or inappropriately
¾
situated on dressers, bookcases, shelves, desks, audio
speakers, chests, or carts. As a result, TVs may fall over,
causing unnecessary injury.
Toshiba Cares!
¾
The consumer electronics industry
is committed to making home
entertainment enjoyable and safe.
¾
The Consumer Electronics
Association formed the Home
Entertainment Support Safety
Committee, comprised of TV and
consumer electronics furniture
manufacturers, to advocate
children’s safety and educate
consumers and their families about
television safety.
Tune Into Safety
¾
One size does NOT fit all! Use appropriate
furniture large enough to support the weight of your
TV (and other electronic components).
¾
Use appropriate angle braces, straps, and anchors to secure
your furniture to the wall (but never screw anything directly
into the TV).
¾
Carefully read and understand the other enclosed
instructions for proper use of this product.
Do not allow children to climb on or play with furniture
¾
and TVs.
Avoid placing any item on top of your TV (such as a VCR,
¾
remote control, or toy) that a curious child may reach for.
Remember that children can become excited while watching
¾
a program and can potentially push or pull a TV over.
Share our safety message about this hidden hazard of

home with your family and friends. Thank you!
