CHILD SAFETY
How and where you use your television wall mount is extremely important for Child Safety
As you set up and use your new product, keep all of these safety tips in mind.
•One size of TV wall mount does not fit all TVs. Use only a TV wall mount rated for the weight of
your TV and the size of your screen. Your TV wall mount assembly instructions contains spe-
cific information on the maximum weight and screen size combination that your wall mount can
safely support. Do not exceed the maximum weight of screen size for any TV wall mount.
•Carefully read all of enclosed instructions for proper use of this product. If you have any doubts
about safe and secure assembly, please contact a professional.
• Don’t let children climb on or play with mounts or TVs.
•Remember that children can become excited while watching a program, especially on a “larger
than life” TV. Make sure to place or install the TV wall mount where it cannot be pushed, pulled
on, or knocked down.
•Make sure that you route all cords and cables so that they cannot be pulled or grabbed by curi-
ous children.
Always wear safety goggles to when drilling or installing hardware.

Step 3: Attach the wall mount to the wall
Step 2. Find and mark the best position for the wall mount on the wall.
The best viewing height is parallel to the eye level of a person sitting on a couch. Normally, this is
about 4 feet above floor level.
In addition to your eye level height when you are seated, the following two measurements will help
you determine the perfect height for your wall-mounted television:
•The distance from your viewing location to the wall.
•The vertical distance from eye level to the floor plus the distance from your viewing location to the
wall when the viewing angle is 15 degrees.
For example:
• If distance ‘a’ is 5 to 7 feet (1.5 to 2.1 meters), distance ‘b’ is about 1 foot (0.3 meter)
• If distance ‘a’ is 8 to 13 feet (2.4 to 4 meters), distance ‘b’ is about 3 feet (0.9 meter)
• If distance ‘a’ is 14 to 17 feet (4.3 to 5.2 meters), distance ‘b’ is about 4 feet (1.2 meters)
Add the eye level height plus ‘b’ to get the ideal height of the center of the television display.
After determining the ideal height on the wall for your television, follow the mounting instructions for
your type of wall construction: wood stud walls or masonry walls (concrete, brick, or stone).

1. The Handles on the front of the Wall Plate mount arm are used to adjust the tilt angle
of the TV to your desired angle.
2. These handles are tension levers. To loosen the tilt adjustment, turn the handle
counter clock-wise until the handle hits the connecting plate and can turn no more.
Then pull the handle away from the mount arm to release the spring as shown in Fig. 5b,
and while holding the handle away from the mount arm, turn the handle clockwise and
release the handle to again engage the spring. Now you can turn the handle further counter
clockwise to loosen the tilt adjustment more.
3. Loosen the other handle slightly and adjust the tilt to your liking and tighten both handles.
4. To tighten these spring loaded handles and lock in the tilt, turn the handles clockwise and
when the handles can turn no further, pull each handle away from the mount arm and then
turn the handle counter clockwise and release. Now you can tighten handle further to lock
in the tilt.
