  Avoid eye exposure to direct laser beam or its close 
reflection 
  Prevent bright light from focussing through the 
eyepiece 
  Never aim the unit at highly reflective objects like 
mirrors and retroreflective surfaces, which are in close 
proximity to the laser rangefinder. This can lead to the 
permanent damage of the photoreceiver incorporated 
into the device.
