Important safety information
Possible Adverse Effects on LCD Screen: If a fi xed (non-moving) pattern remains on the LCD screen
for long periods of time, the image can become permanently engrained in the LCD TV panel and cause
subtle but permanent ghost images. This type of damage is NOT COVERED BY YOUR WARRANTY.
Never leave your TV on for long periods of time while it is displaying the following formats or images:
• Fixed Images, such as stock tickers, video game patterns, TV station logos, teletext pages, and
websites.
• Special Formats that do not use the entire screen. For example, viewing letterbox style (16:9) media
on a normal (4:3) display (Black bars at top and bottom of screen); or viewing normal style (4:3)
media on a widescreen (16:9) display (Black bars on left and right sides of screen).
Attention!
Cleaning instructions for your LCD TV.
Safety note:
Before you start to clean, switch the set's power off completely and disconnect the plug from the mains
power supply.
Be careful not to scratch the plastic coated front panel - it is highly vulnerable to accidental scratching
(e.g. by fi ngernails or other sharp items). (While cleaning, do not wear jewelry) that could cause surface
scratching (such as rings, wrist-watch, etc.). Use a lint-free cloth and pure water to clean with, but make
sure the cloth is thoroughly wrung out so that it is just damp and not soaking wet - also make sure that
the cloth is free from any dirt that could cause scratching to the surface.
Wipe the set clean using minimal pressure.
Do not use standard window cleaning fl uid. Its alcohol / ammonia will dissolve the front window's coating.
Never use solvent or thinner. Never use special cleaners which are designed for cleaning PC Monitors or
CRT TVs. Finally carefully rub dry with a clean dry lint-free cloth.
Do not use paper towels or tissues to clean the set - paper can disintegrate when wet or may leave a trail
of dust behind. Some paper can also be abrasive and scratch your screen.
