	Turn on the power switch, the digital screen shows UV000. Turn the switch of anti-radiation on when all the UV display lights lit up.
	Put the lens on UV lens setting place. If the wave length of the lens is below 360nm, the digital screen shows UV000, which means the effect of anti-ultraviolet ray is bad. If the wave length of the lens is above 360nm, the digital screen shows 360,365,370,375,380,385,390,395,400nm individually. 400nm means the best effect of anti-ultraviolet ray, and 369nm is the worst.
