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 effectively than the 300-ohm twin lead type.
PROGRAMMING PRESETS
Hold the MEMORY SEARCH button down for 2 seconds. The HRS84 will then cycle through the entire FM band as set up MEMORY locations for stations that are available (the station must be strong enough for HRS84 to recognize). After the MEMORY SEARCH is complete you can press the MEMORY UP or DN buttons to access the preset channels.
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 unit’s power and plugging it back in). The full stereo separation will be restored. If you experience poor stereo sound form a selected channel this will remedy the situation.
Multipath reflections
FM waves, like light waves, travel in a straight direction unless reflected off 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 reflected off 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 phenomenon is called “multi-path reflection”. To reduce this problem, select an antenna with good directivity and place it in the best location with strong reception.
