WEEE Notice
The Directive on Waste Electrical and Electronic Equipment (WEEE), which entered into force
as European law on 13th February 2003, resulted in a major change in the treatment of
electrical equipment at end-of-life.
The purpose of this Directive is, as a first priority, the prevention of WEEE, and in addition, to
promote the reuse, recycling and other forms of recovery of such wastes so as to reduce
disposal.
The WEEE logo (shown at the left) on the product or on its box indicates that this product must
not be disposed of or dumped with your other household waste. You are liable to dispose of all
your electronic or electrical waste equipment by relocating over to the specified collection point
for recycling of such hazardous waste. Isolated collection and proper recovery of your
electronic and electrical waste equipment at the time of disposal will allow us to help conserving
natural resources. Moreover, proper recycling of the electronic and electrical waste equipment
will ensure safety of human health and environment. For more information about electronic and
electrical waste equipment disposal, recovery, and collection points, please contact your local
city centre, household waste disposal service, shop from where you purchased the equipment,
or manufacturer of the equipment.
