CONNECTIONS
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.
■ 75-ohm/300-ohm antenna adapter
(U.K. model only)
1 Open the cover of the
included 75-ohm/300-ohm
antenna adapter.
2 Cut the external sleeve
of the 75-ohm coaxial
cable and prepare it for
connection.
3 Cut the lead wire and
remove it.
4 Insert the cable
wire into the slot,
and clamp it with
pliers.
5 Snap the cover
into place.
■ FREQUENCY STEP switch
(Asia and General models only)
Because the interstation frequency
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.
