8. Disposal
This device contains a non-removable and nonrechargeable lithium batte-
ry. Batteries contain substances, which could harm the environment and
might endanger human health if not disposed of properly. To reduce the
disposal quantity so as unavoidable pollutants from electrical and electro-
nic equipment in waste, old equipment should be reused prior or materials
recycled or reused as another form. This is only possible if old equipment,
batteries, other accessories and packaging of the products are returned to
the manufacturer or handed in at recycling centers. Our business processes
generally provide that we or the specialist companies we use take old
devices including batteries, other accessories and packaging material back
with us after they have been replaced or at the end of their useful life and
dispose of them properly.
Insofar as no other contractual arrangement has been made in this respect,
your local or municipal authority or the local waste disposal company can
give you information relating the collection points for your used equip-
ments. ZENNER will always ensure correct disposal.
Caution!
Do not dispose of the devices with domestic waste. In this way, you will
help to protect natural resources and to promote the sustainable reuse of
material resources.
