1. Passed the national safety inspection and certification for mining equipment.
2. Applicable to various application scenarios.
3. Anti-rust and wear-resistant.
4. All-metal housing, sturdy and shock-resistant, easy to adjust, and simple to use.
5. The light output uses optical glass with high transmittance, which not only has the characteristics of anti-fouling and wear resistance, but also has the advantages of concentrating the energy of the emitted light beam, clear spot imaging, and high recognition.
6. The 3-pin aviation connector features a flame-retardant insulated housing for enhanced safety and corrosion resistance. Its secure locking mechanism ensures stable, vibration-proof connections that maintain uninterrupted current transmission.
7. Adjustment buttons allow for easy fine-tuning in the horizontal direction. The operation is simple and the spot positioning is accurate. After locking and securing, the light beam will not deviate.

Precautions：
1. Before use, carefully inspect the appearance of the pointer for any damage and check if all components are loose or missing. Pay special attention to the optical system and mechanical parts to ensure they are functioning properly.
2. Check if the operating environment is suitable for the instrument. Avoid using it in harsh conditions such as strong light, strong wind, high or low temperatures, or humidity, as these may affect measurement accuracy or damage the instrument.
3. For laser pointers, never look directly at the laser beam to prevent eye damage. When operating, wear appropriate protective glasses and ensure the laser beam does not accidentally hit anyone's eyes.
4. During measurement, precisely adjust the direction and angle of the instrument.
5. Avoid using the pointer in strong magnetic fields or environments with electromagnetic interference, as this may affect measurement results. If use is necessary in such environments, take appropriate shielding measures.
6. After use, promptly clean the instrument's surface, especially the optical components and laser exit window. Gently wipe with a soft cloth or lens paper. Do not use chemical reagents to avoid damaging the surface.
7. Store the instrument in a dry, cool place free from corrosive gases. Avoid prolonged exposure to moisture or high temperatures, which may affect the performance and life of the instrument.
8. Regularly maintain and service the instrument, including checking for mechanical wear, cleaning the optical system, and calibrating the instrument. For laser pointers, also regularly check the performance of the power supply and replace any aged or damaged components.
9. Regularly maintain the battery by charging and discharging it. Avoid long-term overcharging or overdischarging. When storing for a long time, it is recommended to remove the battery to extend its lifespan.
10. During transportation and use, avoid subjecting the instrument to severe vibrations or impacts to prevent damage to internal components.
