• The AM loop antenna should always be connected, even if an
outdoor AM antenna is connected to this unit.
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 the nearest authorized YAMAHA
dealer or service center about the outdoor antennas.
