WARRANTY
All fiber optic transmission systems, products and accessories
manufactured by Liteway, Inc. and it’s subsidiaries are fully tested prior
to shipment and are warranted against defective materials and
workmanship for a period of five full years from the date of the original
shipment. Should a problem occur, a Return Material Authorization
Number (RMA) must be obtained from Liteway Inc. at (516) 931-2800
and the item returned to Liteway, Inc. 166 Haverford Road, Hicksville,
NY 11801, USA, prepaid. Liteway Inc. will then, at its option repair or
replace the defective item.
Liteway, Inc. maximum liability under this warranty is limited to the cost
of the defective item only. No contingent liabilities of any kind are either
assumed or implied.
Any items returned to Liteway, Inc. that have been misused, abused,

instructions furnished by Liteway, Inc. or repaired by unauthorized
personnel will not be covered by this warranty. Any non-warranty
repairs required will be quoted at the current rate for such services.
!
CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All -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 of any
kind.

The diagram below shows the typical installation of the VAT-1001 and
VAR-1001 fiber optic video/audio transmission units. Both should be
connected as shown and a video signal applied to the transmitter. To
compensate for the unique fiber optic losses of your installation there
is a level adjustment on the VAR-1001. The receiver video Level
adjustment should then be set for a 1 Volt pp 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. The audio channels do not require any adjustments.

The audio input and output are transformer coupled and may be used
in either a balanced or an unbalanced configuration.
Balanced input or output:
Connect audio to Pin 1 and 2. (4 & 5 for channel 2)
Pin 3 is then used as a shield or unconnected.
Unbalanced input or output:
Connect audio signal to Pin 1 (5 for channel 2).
Connect audio return (and/or shield) to Pin 2 (4 for channel 2).
Connect jump Pin 2 (4 for channel 2) to Pin 3 (ground).
In both cases be certain that the audio input level does not exceed 1Volt RMS (3 volts peak-to-peak) or distortion and/or clipping will
occur.
Alarm Switch
The Alarm is used to turn the video alarm function on and off. This is
utilized when the Alarm sensing unit, ALM-1000 is being utilized.

the Link indicator will go off. The alarm switch cannot disable the
function of the indicator lights.
