10 Disposal
10.1 Product
This symbol must appear on any electrical and electronic equipment placed on
the EU market. This symbol indicates that this device should not be disposed of
as unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose
of it separately from unsorted municipal waste. Spent batteries and accumulators,
which are not enclosed by the WEEE, as well as lamps that can be removed from
the WEEE in a non-destructive manner, must be removed by end users from the
WEEE in a non-destructive manner before it is handed over to a collection point.
Distributors of electrical and electronic equipment are legally obliged to provide free take-
back of waste. Conrad provides the following return options free of charge (more details on
our website):
■
in our Conrad offices
■
at the Conrad collection points
■
at the collection points of public waste management authorities or the collection points
set up by manufacturers or distributors within the meaning of the ElektroG
End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply
in countries outside of Germany.
10.2 (Rechargeable) batteries
Remove batteries/rechargeable batteries, if any, and dispose of them separately from the
product. According to the Battery Directive, end users are legally obliged to return all spent
batteries/rechargeable batteries; they must not be disposed of in the normal household
waste.
Batteries/rechargeable batteries containing hazardous substances are labelled
with this symbol to indicate that disposal in household waste is forbidden. The ab-
breviations for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury,
Pb = Lead (name on (rechargeable) batteries, e.g. below the trash icon on the
left).

Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations
and contribute to environmental protection.
Batteries/rechargeable batteries that are disposed of should be protected against short cir-
cuit and their exposed terminals should be covered completely with insulating tape before
disposal. Even empty batteries/rechargeable batteries can contain residual energy that may
cause them to swell, burst, catch fire or explode in the event of a short circuit.
