Laser Safety Warnings
The RainDrop Sense, classified as a Class 2 System, contains a Class 3B laser and Class 2
barcode laser. Avoid direct exposure to the Class 3B laser radiation when the unit is open
and interlocks are defeated. Only a qualified service person should remove the cover or
attempt to service this device, due to possible eye injury.
A laser warning indicates that the user must use precautions when operating the instrument
to avoid injury from the lasers.
Warning:
A Class 3B laser is hazardous if the eye is exposed directly, but diffuse
reflections such as those from paper or other matte surfaces are not harmful. The
AEL for continuous lasers in the wavelength range from 315 nm to far infrared is
0.5 W. For pulsed lasers between 400 and 700 nm, the AEL is 30 mW. Other
limits apply to other wavelengths and to ultrashort lasers. Protective eye wear is
typically required where direct viewing of a class 3B laser beam may occur. Class-
3B lasers must be equipped with a key switch and a safety interlock.
In addition, users should take precautions in accordance with local, state, and national
requirements.
