13 Disposal instructions for countries in the EU

To conserve and protect the environment, prevent environmental pollution and improve the recycling of

return of electrical and electronic units for proper disposal or recycling.
Within the European Union, units with this symbol should not therefore be disposed of in unsort-
ed domestic waste.
For more information regarding proper disposal please apply at your local authorities.
