Important Information About Using the FM/AM Tuner
Computer equipment uses high-frequency digital circuits that may cause interference on
radio and television equipment located nearby. If interference is a problem with the
RP-U100, and you cannot obtain good reception, or the auto tuning functions don’t
work properly, try the following.
• Move the indoor FM or AM loop antenna as far away from the computer and monitor
as physically possible and find the position and direction at which reception is the best.
• FM outdoor antennas offer the best performance and should be used when the good
reception is not available. Be sure to use coaxial cable to connect to an outdoor
antenna. Use the supplied F-type adapter to connect an outdoor FM antenna with an
F-type connector.
• If you cannot obtain good AM reception using only the AM loop antenna, connect 5 to
10 meters (16 to 32 ft.) of ordinary PVC coated wire to the AM connector on the
RP-U100, feed it through a window, or other outlet, and extend it horizontally. Be sure
to also connect the AM loop antenna. Using another piece of wire, connect the GND
connector on the RP-U100 to a good ground point, such as a grounding rod. Never
connect the RP-U100 to a metal gas or oil pipe, which would cause a safety hazard, or
a plastic water pipe.
