Multi path reections
FM waves, like light waves, travel in a straight direction unless reected
o objects in their path. Because of this, two sets of waves reach your
antenna from the FM station; those that have traveled directly to the
antenna, and those that have been reected o buildings or mountains.
When the antenna receives both kinds of signals, the two interfere with
each other and result in distorted sound and poor separation. This phe-
nomenon is called "multi path reection". To reduce this problem, select
an antenna with good directivity and place it in the best location with
strong reception.

SPECIAL NOTE ABOUT STEREO RECEPTION
When changing presets or adjusting station tuning you may experience
a loss of stereo separation. By cycling the power (unplugging the units
power and plugging it back in). The full stereo separation will be re-
stored. If you experience poor stereo sound form a selected channel this
will remedy the situation.

FM Antenna
INDOOR FM ANTENNA
- Connect the antenna to its corresponding input on the rear panel of the HRs84. While listening
to a broadcast, move around until the antenna is facing a direction where the signal comes in
the strongest. Secure the antenna in this position.
OUTDOOR FM ANTENNA
- Installation of an outdoor FM antenna is recommended for a very high quality FM reception.
- The lead-in antenna cable should be of the 75-ohm coaxial type as it suppresses intrusion of
noise more eectively than the 300 ohm twin lead type.
