13. Disposal

Electronic devices are recyclable waste and must not be placed in household waste. At the end of its ser-
vice life, dispose of the product according to the relevant statutory regulations. Remove the inserted battery
and dispose of it separately from the product.

Disposal of used batteries/rechargeable batteries!

You are required by law to return all used batteries. They must not be placed in household waste.
Contaminated batteries/rechargeable batteries are labelled with symbols to indicate that disposal in do-
mestic waste is forbidden. The designations for the heavy metals involved are: Cd=cadmium, Hg=mercury,
Pb=lead (the marking can be seen on the battery, e.g., underneath the refuse bin symbol shown on the left).
Used batteries can be returned to local collection points, our stores or battery retailers.
That way you fulfil your statutory obligations and contribute to the protection of the environment!
