Disposal of Old Equipment and Batteries (Applicable only for European Union and Countries with a Recycling
System)
The disposal of our products and possible recycling of their components after decommissioning has to be
carried out by an accredited recycling company, or the products/components must be taken to applicable
collection points. Such disposal activities must comply with all local laws, guidelines and environmental speci-
fications of the country in which the disposal is done. For the European Union the sustainable disposal of elec-
tronic scrap is defined in the respective regulation for "waste electrical and electronic equipment" (WEEE).
The crossed-out wheelie bin on the products, packaging and/or accompanying documents means
that used electrical and electronic products and batteries must not be mixed with normal house-
hold waste.
According to national legislation, penalties may be charged for incorrect disposal of such
waste.
