iv About This Guide

For Your Safety
For your personal safety, please review the following safety precautions. They
are provided for your protection, and to prevent damage to your Cobra. This
safety information applies to anyone who comes in contact with Cobra.
Laser Safety
Read the laser safety information carefully and follow all safety
precautions. Not following safety precautions could result in hazardous
radiation exposure to your eyes.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
Cobra should never be tilted or turned over while the laser LED is lit.
Cobra Digital Range Sensors (DRS) use a laser diode as the laser source. DRS
laser energy is not dangerous to exposed skin. However, if viewed directly or
from a reflection of a specular (mirror-like) surface for a period of time longer
than the normal human aversion to bright light, the emitted light from those
sources may be harmful to the human eye.
Cobra DRS laser sensors conform to laser safety regulations set forth by the
Code of Federal Regulations 21 (CFR 21) and submitted to the Center for
Devices and Radiological Health (CDRH). DRS sensors also conform to the
IEC-825 (1993) laser safety regulations specified by the International
Electrotechnical Commission (IEC).
Cobra DRS laser sensors meet Class II requirements of the CFR 21 standard and
Class 2 requirements of the IEC-825 European standard.
