Important disposal instructions for batteries and accumulators
EC Guideline 2006/66/EC requires users to return all used and worn-out batteries and accumu-
lators . They must not be disposed of in normal domestic waste . Because our products include
batteries and accumulators in the delivery package our advice is as follows :
Used batteries and accumulators are not items of domestic waste . They must be disposed of in a
proper manner . Your local authority may have a disposal facility; alternatively you can hand them
in at any shop selling batteries and accumulators . You can also return them to the company which
supplied them to you; the company is obliged to accept them .
