Handling Precautions
1 Vibration and Impact Protection
When transporting the instrument, provide protection to minimize risk of severe vibration
or impact. Severe vibration or impacts may affect beam accuracy.
2.Laser Scanning Interference
Particular reflective surfaces such as mirrors and some glass surfaces, can cause beam
reflection that in very rare circumstances can interfere with the laser scanning function. If
this should happen, simply change the location of the laser or cover the reflective surface.

may results in hazardous radiation exposure.
