WARNING –
The use of Laser Class 3R equipment can be dangerous for the eyes. The risk for eye
damage is minimized through the radiation limit of 5 mW (FOCUS 35 at 660 nm).
Do not stare directly into the beam.
Do not direct the beam towards reflective surfaces (prisms, mirrors, metallic surfaces, or
windows) or towards other people.
Precautions should be taken to ensure that persons do not look with an optical instrument directly
into the beam.
Dazzle flash-blindness and afterimages may be caused by a beam from a Class 3R laser product,
particularly under low ambient light conditions. This may result in temporary disturbance of vision.
Do not operate any equipment or vehicles if such disturbance of vision occurs.
In a distance of 80 m (262 ft) from an instrument the radiation conforms to Laser Class 1. In Laser
Class 1 a direct intrabeam viewing is not hazardous.
Take the following precautions while using a Class 3R instrument in order to minimize the risks of
personal injury:
l
Only use the instrument’s Laser Class 3R function when absolutely necessary.
l
Set up the laser beam above or below human eye level wherever practicable.
l
Make sure that the area where the Class 3R instruments are used is marked with appropriate
laser warning signs.
l
Do not measure towards prisms up to 1,000 m (3,280 ft) in reflectorless mode.
l
Make sure that unauthorized personnel do not get access to the instrument.
The Distance Measuring Unit in prism mode produces visible laser light emerging at the center of the
telescope objective. Product conforms to Class 1 in accordance with IEC 60825-1:2014 and IEC 60825-
1:2007 “Safety of laser devices”.
Max. output power
< 20 µW
WARNING –
Class 1 laser products are safe in normal use under reasonable conditions of operation
and are not harmful to the eyes provided that the products are used and maintained in accordance
with the instructions.
