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 for a long time, image sticking may occur on
the borders of the panel.
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.
