Both AM and FM indoor antennas are included with this unit. In general, these antennas should provide sufficient signal
strength. Connect each antenna correctly to the designated terminals.
• A properly installed outdoor antenna provides clearer reception than an indoor one. If you experience poor reception quality, an
outdoor antenna may improve the quality. Consult your nearest authorized YAMAHA dealer or service center about outdoor antennas.
• If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit.
• To minimize interference from automobile ignition, locate the antenna as far from heavy traffic as possible.
• Keep the feeder cable or coaxial cable as short as possible. Do not bundle or roll up excess cable.
• The antenna should be placed at least 2 meters from reinforced concrete walls or metal structures.
