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.
Connecting the AM loop antenna
1
Set up the AM loop antenna, then connect it 
to the terminals on this unit.
2
Press and hold the tab to insert 
the AM loop antenna lead wires 
into the AM ANT and GND 
terminals. 
3
Orient the AM loop antenna 
for the best reception.
• The AM loop antenna should be placed away from this unit.
• 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 outdoor 
antennas.

FREQUENCY STEP switch
(Asia and General models only)

spacing differs in different areas, set 
the FREQUENCY STEP switch 
(locating on the rear panel) according 
to the frequency spacing in your area.
• North, Central and South America: 100 kHz/10 kHz
• Other areas: 50 kHz/9 kHz
Before setting this switch, disconnect this unit’s power 
cord from the AC wall outlet.
