WARNING
Use of controls or adjustments or performunce of procedures other than those
specified herein may result in hazardous radiation exposure.

WARNING
• Do not directly stare into the laser beams or specularly reflected light. Doing
so may result in serious eye injury. Do not direct laser beams towards a human
body intentionally although laser beams will not cause damage even if it
strikes exposed skin.
• Never disassemble HR-51. HR-51 is not equipped with a mechanism to stop
laser emission when disassembled. If HR-51 is disassembled, laser beams
emitted from HR-51 may cause eye injury.
• Before cleaning the transmitter/receiver part of laser scanner, be sure to stop
the emission of laser beams. Otherwise, exposure to the laser may cause eye
injury.
• Be careful of the light path of laser beams.
Be especially careful of the specularly reflected light.
Do not install HR-51 in such a way that the laser beam passes at eye height
when operating HR-51.
