5. The audio/video reception is not clear.
• The GA-253 uses the 2.4 GHz frequency
range which is also used by microwave
ovens, cordless phones and wireless LANs.
If any two such devices are operating at the
same time, interference occurs. While this
situation is difficult to prevent, switching
to different channels can help.
• Because the 2.4 GHz frequency resonates
with water, transmission is sensitive to
weather conditions and moving people.
Poor transmission quality can be improved
by adjusting the location, angle or direc-
tion of the antennas.
6. The transmission distance is less than 300 feet
(~100 meters).
• Transmission distance is highly dependent
on environment factors including weather
and building structure. The steel frame-
work in a reinforced concrete building will
absorb RF signals and reduce the transmis-
sion range. Adjust the antennas on the
receiver(s) and transmitter(s) to get opti-
mal performance.
