Claims under the warranty rendered void!
The housing of the LMS5xx is sealed. Type-dependent, the devices have a diffent quanitity
of sealing stickers across their components. Claims under the warranty against SICK AG will
be rendered void if the screwed housing is opened and/or the seals are damaged.
The housing is only allowed to be opened by SICK authorized service personnel.
The only exception in this case is the process of replacing an LMS500 Lite/Pro Indoor or
