Danger to life due to reflection
If you do not comply with the minimum distances, objects or persons cannot be
safely detected in the beams of the protective equipment.

When aligning the protective equipment, ensure that the minimum distance
to reflective objects or surfaces on all sides of the protection field is
observed.
The required minimum distances are listed in the table in this
documentation.

Do not operate the protective equipment if diffuse dispersive media are
present.
