Safety instructions

Laser Safety: This device uses a Class 2 laser (< 1 mW, 635 nm). Do not stare into the direct or reflected beam. Do not point the laser at persons. If the laser hits your eyes, close them immediately and move your head out of the beam path. Do not use optical instruments like magnifying glasses or binoculars to view the laser beam.

Electromagnetic Radiation: The device complies with EMC-Directive 2014/30/EU. Be aware of local operating restrictions in areas such as hospitals, aircraft, petrol stations, or near people with pacemakers.

Important usage notes

• Measurement Path: Ensure no objects obstruct the laser's line of measurement.
• Temperature Adaptation: Allow the device a brief adaptation period when moving between locations with significant temperature differences.
• Outdoor Use: The device has limited outdoor usability and cannot be used in strong sunlight. Rain, fog, and snow can influence or falsify results.
• Surface Reflectivity: Carpets, upholstery, and curtains do not reflect the laser optimally. Use flat, smooth surfaces for best results.
• Glass: Measurements taken through glass (window panes) may be inaccurate.
• Energy Saving: The device features an automatic shut-off function.
