13.6.3 Distancer, Measurements without Reflectors (Reflec-
torless mode)
General The EDM module built into the product produces a visible laser beam which
emerges from the telescope objective.
The laser product described in this section is classified as laser class 3R in
accordance with:
• IEC 60825-1 (2007-03): "Safety of laser products".
• EN 60825-1 (2007-10): "Safety of laser products".
Class 3R laser products:
Direct intrabeam viewing may be hazardous (low-level eye hazard), in partic-
ular for deliberate ocular exposure. The risk of injury for laser class 3R prod-
ucts is limited because of:
• unintentional exposure would rarely reflect worst case conditions of (e.g.)
beam alignment with the pupil, worst case accommodation,
• inherent safety margin in the maximum permissible exposure to laser radi-
ation (MPE), natural aversion behaviour for exposure to bright light for the
case of visible radiation.
