For Safe Laser Use - Class 2 Lasers
• Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.
Reference IEC 60825-1:2007, Section 8.2.
Class 2 Lasers
Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400
nm to 700 nm, where eye protection is normally afforded by aversion responses,
including the blink reflex. This reaction may be expected to provide adequate
protection under reasonably foreseeable conditions of operation, including the use of
optical instruments for intrabeam viewing.

Class 2 Laser Safety Notes
Low-power lasers are, by definition, incapable of causing eye injury within the
duration of a blink (aversion response) of 0.25 seconds. They also must emit only
visible wavelengths (400 to 700 nm). Therefore, an ocular hazard may exist only if
individuals overcome their natural aversion to bright light and stare directly into the
laser beam.
Output: < 1.0 mW
Laser wavelength: 640 to 670 nm
Pulse Duration: 20 µs to 2 ms

1.4.1 Display and Indicators
The display is a 4-digit, 7-segment LED. Run mode is the primary view displayed.
For 2-pt, BGS, FGS, and DYN TEACH modes, the display shows the current distance to the target in centimeters. For dual
TEACH mode, the display shows the percentage matched to the taught reference surface. A display value of
indicates the sensor has not been taught.
