Unrestricted locations are areas, normally accessible to the public (e.g., unrestricted areas of rooftops, public areas at ground level, open areas of offices and industrial premises, etc.). To install a KORUZA v2 Pro in an unrestricted location, the link head must be installed 3 meters high or higher above the surface of the unrestricted area, or must be 1 meter or closer to the edge of the unrestricted area. If a KORUZA v2 Pro is installed in an unrestricted area, a warning sticker must be placed on the unit, stating βDo not use binoculars, telescopes or other optical aids to view the FSO link heads.β
