EMC Regulatory Notices
Federal Communications Commission (FCC) Part 15 Information: This device complies
with Part 15 of the FCC standard rules. Operation is subject to the following conditions:
This device may not cause harmful interference
This device must accept any interference received including interference that may cause
undesirable operations.
Delivery Damage Inspection
Carefully inspect the frame and exterior components to be sure that there has been no
shipping damage. Make sure all modules are seated correctly and have not detached
during shipment.
Factors Affecting Quality of Results
There are many factors affecting the quality of results when signals are transmitted from
a source to a destination.
Signal cables — Use only the best quality cables to avoid interference and
degraded signal quality and elevated noise levels.
Sockets and connectors of the sources and destinations — Use only the
highest quality, since "zero ohm" connection resistance is the target.
Connectors should also match the required impedance (75 ohm in
video) to minimize return loss.
Amplifying circuitry — Must have quality performance when the desired
end result is high linearity, low distortion, and low noise.
Distance between sources and destinations — Plays a major role in the final
result. For long distances (over 15 meters) between sources and
destinations, special measures should be taken to avoid high frequency
cable losses. These measures include using higher quality cables and/or
adding line cable equalizing amplifiers.
Interference from neighboring electrical appliances — These can have an
adverse affect on signal quality. Balanced audio lines are less prone to
interference, but unbalanced audio should be installed away from any
main power lines, electric motors, transmitters, etc. even when the
cables are shielded.
CAUTION!
Only an authorized Sierra Video technician can service these products. Any user who
