POSSIBLE EXPLOSION HAZARD. Equipment not suitable for use in the presence of a flammable
thetic
mixture with air or with oxygen or nitrous oxide.
This system should only be used by qualified medical personnel.
WARNING: THERE IS A RISK OF
TION. THE RISK OF INJURY IS REDUCED BY
ESSARY, BY MINIMIZING EXPOSURE TIME, AND BY AVOIDING CLOSE STATIONARY VIEWING.
WARNING: The high intensity light at the front of the light source and at the tip of a fiber optic bundle may
give rise to high temperatures. To minimize the risk of injury, avoid contact with tissues.
WARNING: As with any bright light, do not look into the beam. Permanent
To reduce the chance of direct visual exposure to the light, set the light intensity knob to the minimum
level and plug the fiber optic bundle into the light source before turning the power ON.

With the output of high intensity (Xenon) light sources, it is possible to convey a large amount of light energy and to
concentrate this energy in a very small area. This may result in thermal injury to the tissue.
The risk of injury is increased under the following
1.
Prolonged close contact or close stationary viewing of the mucosa or tissue.
2.
Using a high intensity light source at high output levels.
3.
Using multiple instruments to illuminate the same area.
conditions:
The following recommendations will reduce the risk of thermal injury:
1.
Use
the minimum level of illumination necessary for adequate visualization.
2.
When possible, avoid close stationary viewing.
3. Minimize exposure time.
