The equipment is a Class I LED Product. The LED used for the equipment is safe under expected
use conditions including situation such as looking into the LED using optical equipment.
However, observe the following precautions when using the equipment

Do not direct LED beams to human eyes when unnecessary.
 Do not look into the objective lens for a prolonged time.
 Class 3R invisible LED radiation when Optical system subassembly open.
Avoid exposure to the beam.
 The longer the duration of exposure and the greater the number of pulses, the greater
the risk of ocular damage. Exposure to light from this instrument when operated at
maximum output will exceed the safety guideline after 9.9 x 10 7 sec for Retina IR, 5.3 x

sec for Kerato ring(Auto / Manual
Tracking), 9.5 x 10 7 sec for Kerato focus(Auto/Manual Tracking), 1.0 x 10 8 sec for Split
focus(Optimizing), 9.1 x 10 5 sec for external fixation lamp, 4.8 x 10 7 sec for SLD
Laser(OCT scanning), 1,936,114 pulses for the light source of fundus image capture
Note 1: The exposure time and number of pulses from all light sources is cumulative
and additive.
Note 2: If the intensity of any of the light sources is reduced to 50% of the maximum
intensity, the exposure time or number of pulses for that light source to reach the
exposure guideline is doubled. This linear relationship can be used to determine the
time to reach the exposure guideline for the combination of light sources at various
intensity settings.
Note 3: The weighted retinal radiant exposure guideline is 10 J/cm2
