Important safety information
Moving the unit or carrying by hand
When the unit is moved a long way, unplug the power cord and disconnect the aerial, connect-
ing cables and any fall-prevention apparatus.
• Moving without doing so could result in damage to the power cord, a fi re, electric shocks or injuries
from dropping the unit.
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 specifi c
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 5 ~ 7 times as long as diagonal length
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.
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.
Saving electricity
The high energy consumption during operation is reached only with maximal brightness of the display
light. Maximal 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. 17). 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. 17), 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 consump-
tion with switched on DBC.
Note:
• Maximal contrast values are reached only with a maximal setting (16) 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 16 and turn off the DBC.
