Storage and Handling
Usage precautions
- The Lixel L3 is a precision surveying instrument. Drops or impacts can damage it and reduce accuracy.
- The Lixel L3 is rated IP54. Do not use it in conditions beyond this rating. Clean it with a soft, dry cloth or the supplied cleaning cloth, and do not touch the LiDAR or lenses with your fingers.
- The body gets hot during use. Avoid touching it to prevent burns.
- Keep the heat dissipation area uncovered. The device may shut down if it overheats.
