Recycling Information
WEEE (Waste of Electrical and Electronic Equipment), Recycling of Electronic Products

Europe, United Kingdom
In 2006 the European Union introduced regulations (WEEE) for the collection and recycling of all waste electrical and electronic equipment. It is no longer allowable to
simply throw away electrical and electronic equipment. Instead, these products must enter the recycling process.
Each individual EU member state has implemented the WEEE regulations into national law in slightly different ways. Please follow your national law when you want to
dispose of any electrical or electronic products. More details can be obtained from your national WEEE recycling agency.

Battery Remark:
Do not put empty batteries in your domestic waste bin as they will not be recycled. Empty batteries can be returned for recycling at our trade counter or at your local
household recycling center.
The raw materials enclosed in batteries such as Zinc, Iron, and Nickel can be reused in a very large proportion. The recycling of batteries and disused/obsolete electronic
equipment is one of the most efﬁcient environment protection actions you can easily take.

Tested to comply with FCC standards.
