monitor. This may lead to an electrical short-circuit or even fire
resulting in damage to your LCD monitor.
• Slots and openings in the LCD monitor are for ven-
tilation purpose. Do not cover these openings,
as this may lead to overheating.
• Do not allow children to play unattended with electrical
equipment. Children may not always correctly recognize
danger.
• This LCD monitor is intended for personal use only. It not
intended for commercial use in a heavy industry environ-
ment.
• An injury hazard exists when the display breaks. Wear pro-
tective gloves to pack the broken parts and send them into
your service center for proper disposal. Then wash your hands
with soap, because it is possible for chemicals to escape.
• Never exert pressure on the display. This could break the moni-
tor.

♦ if the LCD monitor is dropped or the housing damaged
REPAIR
• Leave all repairs of your LCD monitor to authorized and
qualified personnel only.
• Should a repair be necessary, please contact one of our author-
ized service partners only.
NOTES FOR SERVICE ENGINEERS
• Before opening the housing, disconnect the monitor from all
power sources and remove any connecting cables. If the moni-
tor has not been disconnected from the power outlet before being
opened, there is a danger to life through electric shock. There is
also a risk of damage to the components.
• Internal components of the LCD monitor may be damaged by electrostatic discharge (ESD). Carry out repairs in an ESD-protected
workshop. If no such workshop is available, wear an antistatic
wrist strap or touch a highly conductive metal object. We can re-
pair damage sustained by inappropriate handling for a fee.
• Use only original spare parts.

POINT OF USE
• Keep your LCD monitor and all units connected to it away from
moisture and avoid dust, heat and direct sunlight. Failure
to observe these instructions can lead to malfunctions or damage to the LCD monitor.
• Place and operate all units on a stable, level and vibra-
tion-free surface in order to avoid the LCD monitor from
falling.
ENVIRONMENTAL CONDITIONS
• The LCD monitor can be operated most reliably at ambient
temperatures between +41°F and +95°F (5° C to 35° C) and
at a relative humidity between 20% and 85% (without condensation).
• When switched off, the monitor can be stored most reliably be-
tween -4°F and +140°F (-20° C - +60° C), up to the maximum height of 39,000 ft (12,000 m) above sea level at a relative humidity between 10% and 85% (without condensation).
• After transporting your LCD monitor please wait until it has
assumed the ambient temperature before connecting and
switching it on. Extremely high variations in the temperature
or humidity may result in condensation forming on the inside of the LCD monitor which could cause an electrical
short-circuit.

their extremely complex production process occasionally defective or incorrectly
addressed pixels or sub-pixels may occur.
There have been several attempts in the past to define the acceptable number of
defective pixels. But this can be difficult and varies widely between different
manufacturers.
MEDION, therefore, adheres to the clear
and strict requirements of ISO 13406-2,
class II, for the warranty handling of all
TFT display products. These requirements
are summarized below.
Within ISO-standard 13406-2 the general
requirements regarding pixel defects are
defined. Pixel defects are classified into three
failure types and four failure classes. Each
individual pixel is made up of three sub-pixels
in the primary colors (red, green, blue).
Types of Pixel Failures:
Type 1: A constantly lit pixel (a bright, white spot), even though it is not
Type 2: A pixel that does not light up (dark, black spot), although it is ad-
Type 3: Abnormal or defective red, green or blue sub-pixels.
In addition: A cluster of type 3 (= 2 or more defective sub-pixels in an array of 5
Classes of Pixel Failures:

A white pixel is caused when all three sub-pixel are lit.

The acceptable number of defects of the above mentioned types in each failure
class refers to one million pixels and has to be calculated according the physical
resolution of the display.

This leads to a maximum allowed number in class II type failure:
Resolution
1024 x 768 (15") 0.786432 2.359296 2 2 4 - 2
1280 x 1024 (17,18, 19") 1.310720 3.932160 3 3 7 - 3
1600 x 1200 (19“) 1.920000 5.760000 4 4 10 - 4
Class I type failure only applies to special applications, e.g. medical applications,
and results in corresponding price increases. Class II type failure is the established
standard for quality conscious manufacturers with high quality displays.
Example 1:
A 15” - XGA-display consists of 1024 horizontal and 768 vertical picture dots
(pixel), which amounts to a total of 786,432 pixel. Related to one million pixels
this translates into a factor of about 0.8.
Class II type failure consequently allows for two defects each of type 1 and type 2
and 4 defects of type 3 and 2 clusters of type 3.
Example 2
A 17” - SXGA-display consists of 1280 horizontal and 1024 vertical picture dots
(pixel), which amounts to a total of 1,31 million pixels. Based on one million pixels
this translates into a factor of about 1.31.
Class II type failure consequently allows for three defects each of type 1 and type
2 and 7 defects of type 3 and 3 cluster of type 3.
These cases are normally not covered by warranty.
If the number of failures exceeds the figures of any category mentioned above
then this may be covered by the warranty.
