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

disposal of lithium batteries:

Warning

Improper handling of lithium batteries represents a risk of explosion – therefore,

lithium batteries:

• should never be recharged

• should never be opened

• should never be short circuited

• should never be reverse poled

• should never be heated over 100 °C

• should be protected from direct sunlight.

Condensation must not form on lithium batteries.

Only replace lithium batteries with those of the same type or one recommended by

the manufacturer.

Used lithium batteries do not belong in normal, household waste. They must be

disposed of individually as special waste, packed in a sealed plastic bag.

In the case of transport, applicable regulations on dangerous goods must be

observed by the respective transporting company (identification requirements).
