electrical and electronic products should not be disposed of as municipal waste. Electrical
and electronic products including the cables, plugs and accessories should be disposed of
separately in order to allow proper treatment, recovery and recycling. These products should

stream. This contributes to the protection of human health and the environment. Please be
informed that a fine may be imposed for illegal disposal of electrical and electronic products
via the general municipal waste stream.
In order to facilitate separate disposal and environmentally sound recycling arrangements have been made for local
collection and recycling. In case your electrical and electronic products need to be disposed of please refer to your
supplier or the contractual agreements that your company has made upon acquisition of these products.
At www.nec-philips.com/weee you can find information about separate disposal and environmentally sound
recycling.
For countries outside the European Union
Disposal of electrical and electronic products in countries outside the European Union should be done in line with
the local regulations. If no arrangement has been made with your supplier, please contact the local authorities for
further information.
