Connecting the FM and AM
antennas
Both FM and AM indoor antennas are supplied with this
unit. Connect each antenna correctly to the designated
terminals. In general, these antennas should provide
sufficient signal strength.
Notes
• The AM loop antenna should be placed away from this unit.
• A properly installed outdoor antenna provides clearer reception
than an indoor one. If you experience poor reception quality,
install an outdoor antenna. Consult the nearest authorized
Yamaha dealer or service center about outdoor antennas.
• The AM loop antenna should always be connected, even if an
outdoor AM antenna is connected to this unit.
