PREPARATION Connecting the antennas 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. AM loop antenna (included) Indoor FM antenna (included) CONNECTIONS I 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. TUNER AM ANT GND 75Ω UNBAL. FM ANT Ground (GND terminal) For maximum safety and minimum interference, connect the antenna GND terminal to a good earth ground. A good earth ground is a metal stake driven into moist earth. 75-ohm/300-ohm antenna adapter (U.K. model only) 1 2 11 (7/16) 8 (5/16) Unit: 6 (1/14) mm (inch) Open the cover of the included 75-ohm/300-ohm antenna adapter. Cut the external sleeve of the 75-ohm coaxial cable and prepare it for connection. 3 Lead wire Cut the lead wire and remove it. 4 Clamp with pliers. Clamp with pliers. Insert the wire into the slot. Insert the cable wire into the slot, and clamp it with pliers. 5 Snap the cover into place. 3 Orient the AM loop antenna for the best reception. Notes • 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 the outdoor antennas. FREQUENCY STEP switch (China and General models only) FM/AM 50kHz/9kHz 100kHz/10kHz Because the inter-station frequency spacing differs in different areas, set the FREQUENCY STEP switch (located on FREQUENCY STEP 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 the AC power plug of this unit from the AC outlet. English 13

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.
Notes
•
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 the outdoor antennas.
FREQUENCY STEP switch (China and General
models only)
Because the inter-station frequency
spacing differs in different areas, set the
FREQUENCY STEP switch (located 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 the
AC power plug of this unit from the AC
outlet.

For maximum safety and minimum
interference, connect the antenna GND
terminal to a good earth ground. A good
earth ground is a metal stake driven into
moist earth.
