WEEE-notice

The WEEE (Waste Electrical and Electronic Equipment)-directive, which became 

effective as European law on February 13th 2003, resulted in an all out change 

in the disposal of disused electro devices. The primarily purpose of this directive 

is the avoidance of electrical waste (WEEE) and at the same time the support of 

recycling and other forms of recycling in order to reduce waste. The WEEE-logo 

on the device and the package indicates that the device should not be disposed 

in the normal household garbage. You are responsible for taking the disused 

electrical and electronical devices to a respective collecting point. A separated 

collection and reasonable recycling of your electrical waste helps handling the 

natural resources more economical. Furthermore recycling of electrical waste is 

a contribution to keep the environment and thus also the health of men. Further 

information about disposal of electrical and electronical waste, recycling and 

the collection points are available in local organizations, waste management 

enterprises, in specialized trade and the producer of the device.
