Important Notices
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.

Installation Instructions
The diagram below shows the typical installation of the VT-1001 and
VR-1001 fiber optic video transmission units. Both should be
connected exactly as shown. To compensate for the unique fiber
optic losses of your installation there is a level adjustment on the VR-
1001. Apply video signal applied to the transmitter and set the
receiver level adjustment for a 1-volt peak-to-peak video output
signal, or for an acceptable picture. The range of the receiver level
control is adequate to allow the full 0 - 13dB optical path loss range to
be accommodated.
A dual channel unit, the VR-1002 which consists of two VR-1001
mounted in the same housing to conserve rack space is also
available.
