Standards

This notebook meets the requirements of the following standards:

Electromagnetic Compatibility

•
When connecting additional components, please observe the guidelines on
Electromagnetic Compatibility (EMC). Please note only shielded cables shorter than
9.84 feet should be used for external interfaces (LPT, COM, USB, IEEE 1394,
audio, video and network) with this notebook.
•
Keep the notebook at least three feet away from high frequency and magnetic
interference sources (for example, TV sets, speakers, mobile phones, etc.) in order
to avoid malfunctions and/or loss of data.

Pixel Defects on TFTs (LCD-Displays)

ISO 13406-2 Class II
Active matrix LCDs (TFT) with a resolution of 1280 x 800 pixel (WXGA), which are in turn
composed of three sub-pixels each (red, green, blue), contain about 3.1 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 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).
