How It Is Used
With the batteries fitted, press the button and aim the beam at a screen, board or object; releasing the button turns the laser off. The green beam looks brighter than a red one because the eye is more sensitive to green light, which helps in lit rooms and for pointing out stars at night. Never look into the beam or aim it at people, animals or reflective surfaces.
