Outdoor Antenna Grounding

 

(Can differ by country): 

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.

y

When mounting a TV on the wall, make sure not 

to install the TV by hanging the power and signal 

cables on the back of the TV.

 

y

Do not allow an impact shock or any objects to fall 

into the product, and do not drop anything onto 

the screen.

 

y

DISCONNECTING THE DEVICE FROM THE MAIN 

POWER

 

The power plug is the disconnecting device. 

In case of an emergency, the power plug must 

remain readily accessible.

 

y

Batteries 

 

Store the accessories (battery, etc.) in a safe 

location out of the reach of children.

 

y

This apparatus uses batteries. In your community 

there might be regulations that require you 

to dispose of these batteries properly due to 

environmental considerations. Please contact 

your local authorities for disposal or recycling

y

Dot Defect

 

The panel is a high technology product with 

resolution of two million to six million pixels. 

In a very few cases, you could see fine dots on 

the screen while you’re viewing the TV. Those 

dots are deactivated pixels and do not affect the 

performance and reliability of the TV.

 

y

Generated Sound

 

Cracking noise

 A cracking noise that occurs when 

watching or turning off the TV is generated by 

plastic thermal contraction due to temperature 

and humidity. This noise is common for products 

where thermal deformation is required.  

Electrical circuit humming/panel buzzing

 

A low level noise is generated from a high-speed 

switching circuit, which supplies a large amount of 

current to operate a product. It varies depending 

upon the product. This generated sound does 

not affect the performance and reliability of the 

product.

 

y

Take care not to touch the ventilation openings. 

When watching the TV for a long period, the 

ventilation openings may become hot. This does 

not affect the performance of the product or cause 

defects in the product.

 

y

Do not install this product on a wall if it could be 

exposed to oil or oil mist. This may damage the 

product and cause it to fall.

 

y

If the TV feels cold to the touch, there may be a 

small flicker when it is turned on. This is normal; 

there is nothing wrong with TV. Some minute dot 

defects may be visible on the screen, appearing as 

tiny red, green, or blue spots. However, they have 

no adverse effect on the TV’s performance. Avoid 

touching the LCD screen or holding your finger(s) 

against it for long periods of time. Doing so may 

produce some temporary distortion effects on the 

screen.

Preventing image burn or burn-in 

on your TV screen

 

y

If a fixed image displays on the TV screen for 

a long period of time, it will be imprinted and 

become a permanent disfigurement on the screen. 

This is image burn or burn-in and not covered by 

the warranty.

 

y

If the aspect ratio of the TV is set to 4:3 for a long 

period of time, image burn may occur on the 

letterboxed area of the screen.

 

y

Avoid displaying a fixed image on the TV screen 

for a long period of time (2 or more hours for LCD, 

1 or more hours for the Plasma TV) to prevent 

image burn.

WALL OR CEILING MOUNT YOUR 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.
