1. Connect to a stable 3.7–5 V DC source. Confirm polarity before power-up.
2. Adjust focus by gently rotating the lens barrel until the smallest spot is achieved at your target distance.
3. Allow adequate airflow around the heat-sink fins during extended use.
4. For engraving, secure both the laser and the workpiece to avoid misalignment.

Safety Notice

This laser can cause permanent eye injury and ignite flammable materials. Always use certified protective eyewear rated for 445 nm wavelengths and operate in a controlled environment. Never direct the beam at people, animals or reflective surfaces.
