Packing
Please use the recycling operators known to
you. We can also help you – get in touch with
your nearest sales office. By agreement we
will take packing material back, if it is sorted.
You must bear the costs of transport.
For packing material that is returned to us
unsorted or which we are not obliged to
accept, we shall have to invoice you for any
costs incurred.
Components used in life-support devices
or systems must be expressly authorized

with the
express written approval of the
Semiconductor Group of Siemens AG.
1 A critical component is a component used
in a life-support device or system whose
failure can reasonably be expected to
cause the failure of that life-support
device or system, or to affect its safety or
effectiveness of that device or system.
2 Life support devices or systems are
intended (a) to be implanted in the human
body, or (b) to support and/or maintain
and sustain human life. If they fail, it is
reasonable to assume that the health of
the user may be endangered.
