5 General Information
Faulty pixels in display
A minimum number of faulty pixels in the display cannot be avoided. The following
is permissible:
Pixel number
Permanently light and permanently dark pixels ≤ 12
Permanently light green pixels ≤ 5
The production process for modern flat screens (LCD) does not currently
guarantee that all pixels in the screen are error free. As long as it is not a case of
an accumulation of locally erroneous pixels, there are no relevant functional
restrictions.
Disposal
Please observe the following safety-related information on correct handling and

lithium batteries:
• should never be recharged
• should never be opened
• should never be short circuited
