5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.

Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.
change in installation site, sending for repair).
