SAFETY INSTRUCTIONS
y You may find different brightness and colour of the panel depending on your viewing
position(left/right/top/down).
This phenomenon occurs due to the characteristic of the panel. It is not related with the
product performance, and it is not malfunction.
y Displaying a still image (e.g., broadcasting channel logo, on-screen menu, scene from a video game) for a
prolonged time may cause damage to the screen, resulting in retention of the image, which is known as image
sticking. The warranty does not cover the product for image sticking.
Avoid displaying a fixed image on your television's screen for a prolonged period (2 or more hours for LCD, 1
or more hours for Plasma).
Also, if you watch the TV at a ratio of 4:3 (4:3 or 16:9 for 21:9 model) for a long time, image sticking may occur
on the borders of the panel. When watching the TV for a long period of time, please use the default screen
ratio.
This phenomenon also occurs in third-party products and is not subject to exchange or refund.
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 tempera-ture 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 on
the product.
This generated sound does not affect the performance and reliability of the product.
y Do not use high voltage electrical goods near the TV (e.g. electric mosquito-swatter). This may result in
product malfunction.
