POSITIONING YOUR DISPLAY
■
The image shown may be somewhat different from your set.
Adjust the position of the panel in various ways for maximum comfort.
•• TTiilltt rraannggee
LOCATION
Position your set so that no bright light or sunlight falls directly onto the screen. Care should be taken not to
expose the set to any unnecessary vibration, moisture, dust or heat. Also, ensure that the set is placed in a posi-
tion to allow a free flow of air. Do not cover the ventilation openings on the back cover.
If you intend to mount the set to a wall, attach the wall mounting interface (optional parts) to the back of the set.
When you install the set using the wall mounting interface (optional parts), attach it carefully so it will not drop.
- Be sure to use screws and a wall mount that meet VESA standards.
- Using screws longer than those recommended might damage the product.
- Using screws that do not meet VESA standards might either damage the product or result in it coming away from
the wall. We will not be held responsible for any damage resulting from failure to follow these instructions.

potentia y causing injury or damaging the product.
Caution: P ease make sure that chi dren don’t c imb on or hang from the set.
■Insert the eye-bo ts (or set brackets and bo ts) to tighten the product to the wa as shown in the picture.
*If your product has the bo ts in the eye-bo ts position before inserting the eye-bo ts, oosen the bo ts.
* Insert the eye-bo ts or set brackets/bo ts and tighten them secure y in the upper ho es.
Secure the wa brackets with the bo ts (so d separate y) to the wa . Match the height of the bracket that is
mounted on the wa to the ho es in the product.
Ensure the eye-bo ts or brackets are tightened secure y.
■Use a sturdy rope or cord (so d separate y) to tie the product. It is
safer to tie the rope so it becomes horizonta between the wa and the
product.
