CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All –5, -7, -8, and -9 Models use laser diodes. These solid-state
laser diodes are located in the optical ports of these units. Laser
diodes produce invisible radiation that may be harmful to human
eyes. Never look directly into the optical port of any fiber optic
unit designed to operate with single-mode optical fiber.
NOT FOR LIFE SUPPORT SYSTEMS
Liteway, Inc. does not authorize or warrant any of its products or
accessories for use in critical life support systems or applications
