WARNING
• While the AQ1200 is producing light, do not remove the optical fiber cable, because light is
emitted from the light source port. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. On models with two or more light source ports, visual impairment may occur if light
that is mistakenly emitted from the wrong port enters the eye.
Use a short optical fiber to connect an AQ1200 light source port to an AQ1200 optical power
measurement port, and then perform optical power adjustment.
