Laser Safety Warning

DANGER — CLASS 3B LASER RADIATION. AVOID DIRECT EXPOSURE TO THE BEAM.

Direct exposure or exposure to mirror-like reflections can cause serious, permanent eye injury.
Never look into the laser aperture or view the beam through binoculars, telescopes, or other optical instruments.
Use laser protective eyewear suitable for the emitted wavelength range and output power. Ordinary sunglasses do not provide suitable protection.
Operate only in a controlled area, keep the beam below eye level, and terminate it with a suitable non-reflective beam stop.
Never aim the laser toward people, animals, vehicles, or aircraft.
Keep away from children and unauthorized users. This product is not a toy.
Disconnect power before installing, adjusting, or servicing the module.

Electrical Notice: Use only a suitable 3–5V DC supply. Do not exceed 5V DC or connect the module directly to AC mains power. Check voltage and polarity before use.
