Consideration of duty according to the battery law
Old batteries do not belong to domestic waste because they could cause damages of health and environment. You can return used
batteries free of charge to your dealer and collection points. As end-user you are committed by law to bring back needed batteries to
distributors and other collecting points!
Consideration of duty according to the law of electrical devices
This symbol means that you must dispose of electrical devices separated from the General household waste when it reaches the end of
its useful life. Take your unit to your local waste collection point or recycling centre. This applies to all countries of the European Union,
and to other European countries with a separate waste collection system.
