the case of misuse.
•
Never open the housing of the TFT monitor (electric shock, short-circuit and the danger of fire)!
•
Do not insert any objects through the slots and openings into the inside of the TFT (electrical shock,
short-circuit and the danger of fire)!
•
Slots and openings in the TFT monitor are for ventilation purpose. Do not cover these openings, as
otherwise this may lead to overheating (overheating, danger of fire)!
•
Never exert pressure on the display. This could break the monitor.
•
An injury hazard exists when the display breaks. Wear protective 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.
•
Do not touch the display with your fingers or with sharp objects to avoid damage.
Please proceed as outlined in the Customer Service section:
•
if the power cable overheats or is damaged
•
if liquid has gotten into the monitor
•
if the TFT monitor is dropped or the housing damaged
Point of use
•
In the first hours of operation, new devices may emit a typical, unavoidable but completely harmless smell,
which will decline increasingly in the course of time.
We recommend you to ventilate the room regularly, in order to counteract the formation of the smell.
During the development of this product, we have made sure that the applicable limits are clearly fallen
below.
•
Keep your TFT 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 TFT monitor.
•
Do not operate your device in the open air, because external influences, such as rain, snow, etc. could
damage the device.
•
Do not place any containers filled with liquid (vases or similar containers) on the device. The
container could tip over and liquid can impair electrical safety.
•
Do not place any open sources of fire (candles or similar objects) on the device.
•
Pay attention to sufficiently large clearances in the wall cupboard. Maintain a minimum clearance
of 10 cm around the device for sufficient ventilation.
•

Intended Environment
•
The TFT monitor can be operated at an ambient temperatures of between +41°F and +95°F
(5° C to 35° C) and at a relative humidity of between 20% and 85% (without condensation).
•
When switched off, the monitor can be stored at between -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 of between 20% and 80%
(without condensation).
•
After transporting your TFT 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 TFT monitor which could cause an electrical short-circuit.
Power Supply
Please pay attention: Pats of the device are still live, even if the mains switch is switched off. Pull
the mains plug out of the socket, to interrupt the power supply to your TFT monitor or to release
the device from voltage completely.
•
Operate your TFT monitor mains (power supply) only on grounded sockets with
AC 100-240V~/ 50-60 Hz. If you are not sure about the power supply at your location, check with your
power company.
•
For additional safety we recommend use of an excessive voltage protection device to protect your TFT
monitor from damage resulting from voltage surges or lightning.
•
To interrupt the TFT monitor from mains (power supply) disconnect the plug from the socket.
•
To avoid power consumption when the device is switched off either pull out the power plug when the
device is not used or connect the device to a master-/slave power bar.
•
The power socket must be in the vicinity of your TFT monitor and within reach of the power cables. DO
NOT stretch the power cables tightly to reach a power socket.
•
If you use an extension cable, ensure that it fulfills the VDE requirements. Please ask your
electrician.
•
You should lay the TFT Monitor cables in a manner that no one can trip or step on it.
•
To avoid damage of cable do not place any objects or furniture on the cable.

Pixel Defects on TFTs (LCD-Displays)
Active matrix TFTs (LCD) with a resolution of 1440 x 900 pixel (WSXGA), which are in turn composed of three
sub-pixels each (red, green, blue), contain about 3.9 million addressable transistors. Because of this very high
number of transistors and 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 addressed
A white pixel is caused when all three sub-pixel are lit.
•
Type 2:
A pixel that does not light up (dark, black spot), although it is addressed
•
Type 3:
Abnormal or defective red, green or blue sub-pixels.
(E.g. constantly lit with half the brightness, one color is not shining, blinking or flickering, but not
belonging to Type 1 or 2 Pixel Failures)
In addition:
A cluster of type 3 (= 2 or more defective sub-pixels in an array of 5 x 5 pixel). A cluster is an array
of 5 x 5 pixel (15 x 5 sub-pixel).

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:

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.
