Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation

can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not

look directly into the optical transmitter of any unit or exposure to laser radiation may result.

An optical power meter should be used to verify active fibers. A protective cap or hood MUST

be immediately placed over any radiating transmitter or optical fiber connector to avoid the

potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles

from entering the connector.

Caution:

Improper handling can damage fiber optic cables. Do not bend fiber optic cable more

sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not

apply more pulling force to the cable than specified.
