FOR YOUR SAFETY

LASER RADIATION

AVOID DIRECT EYE EXPOSURE

CLASS 3R LASER PRODUCT

•Do not remove warning labels from the unit.

•The laser is subject to class 3R (< 5mW, 600 ... 680 nm).

•Due to the small diameter beam, watch and secure the course of the beam in remote areas.

•Never look into the laser beam or direct it to the eyes of other people.

•Always operate the unit in a way that prevents the beam from getting into people’s eyes.

Important Information

•Always place the laser in the middle of the working area.

•Tripod/wall mount operation is recommended for distances over 20 m (65 ft).

•Check the accuracy regularly.

•Stable mounting is necessary for secure operations.

•Keep the glass of the instrument clean.
