Important safety information
WARNING
• To prevent fire, never place any type of candle or open flame
on the top or near the TV set.
Moving the unit or carrying by hand
When the unit is moved a long way, unplug the power cord and disconnect the antenna, connecting
cables and any fall-prevention apparatus.
• Moving without doing so could result in damage to the power cord, a fire, electric shocks or injuries from
dropping the unit.
Ensure that unpacking and transfer of the unit is carried out by two or more people and that the unit
stays upright when doing this.
When the TV stand has casters, remove caster cups from the stand and push it while supporting the
unit.
• Ensure that you support the unit when the stand is pushed, as this can cause the unit to fall and you could
be injured.
• The appliance could leave indentations in wooden tables with extremely soft wooden surfaces due to its
heavy weight.
• Furniture polish could corrode and dissolve rubber feet. Black imprints could be visible on the table. You
should therefore only use TV benches, which have been constructed for this specific purpose.
Secure the casters when the unit is installed on a TV stand with casters.
• The stand can move and you could be hurt if the casters are not secured.
Remove casters when the stand is placed on a soft surface such as a mat and carpet.
The distance between eyes and the screen should be about 3 ~ 4 times as long as height of the screen.
• Viewing from too close a distance can cause strain for your eyes.
When installing the Monitor on a table, be careful not to place the edge of its stand.
• This may cause the Monitor to fall, causing serious injury to a child or adult, and serious damage to the
Monitor.
Possible Adverse Effects on LCD Screen: If a fixed (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 perma-
nent 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, 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
fingernails 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 fluid. 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.
Saving electricity
The high energy consumption during operation is reached only with maximal brightness of the display light. Maxi-
mal brightness is only necessary in a daylight environment in order to get a luminous and full of contrast picture.
With less light in the environment, e.g. in the evening, the picture already can be too bright and might dazzle. The
brightness of the display light can be reduced to the desired value in the menu Backlight (see p. 19). If the Backlight
is set to a smaller value you can save up to 30 % of energy.
If there is set DBC (Dynamic Backlight Control) (see p. 19), the brightness of the display light changes depending on
the video signal. The energy consumption changes with the brightness of the video scenes. Darker scenes consume
less energy than bright scenes. Thus in average one gets less energy consumption with switched on DBC.
Note:
• Maximal contrast values are reached only with a maximal setting of Backlight.
• The biggest energy saving effect is reached with minimal setting of Background.
• With dimmed display light as well as with turned on DBC one can hear a low humming sound on technical
reasons. This is normal and no reason to worry about. There is no production fault because of that. If the low
humming in exceptional cases should disturb in an extremely quiet environment, reset the value of Backlight to
the factory setting and turn off the DBC.
