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

Compensation for short or long fiber runs
On the VR-4005 there is a level adjustment to compensate for very
short or very long fiber optic cable installations. On most typical
installations no adjustment is needed. To make the adjustment, apply
a video signal applied to the transmitter and view the picture on the
TV receiver. If you do not have an acceptable image, turn the VR4005 front panel adjustment as follows;
If the picture appears noise turn the pot clockwise.
If the picture tears, turn the adjustment counter-clockwise.
