10.2. AM Antenna Connections
10.2.1. When using the supplied AM loop antenna
Connect the supplied AM loop antenna to the AM antenna terminals.
Use the supplied AM loop antenna to receive broadcasts if satisfactory reception can be obtained.
Adjust the loop antenna’s position for the best possible reception while listening to AM broadcasts.
Notes
• When using the supplied AM loop antenna, keep it as far away as possible from speaker cables, audio
cables, power cables, and AC adapter.
• Connect the loop antenna cables to the antenna terminals so that their cable core wires are exposed several
millimeters from the terminals. When the exposed core wire of the antenna cable is too long, cut it to an
appropriate length.

10.2.2. When using an external antenna
If satisfactory AM band reception cannot be obtained with the supplied AM loop antenna, connect a commercially
available AM antenna or a long-wire antenna externally. Connect a cable core of the solid wire or the coaxial
cable to one of the AM antenna terminals.
It is recommended that a long-wire antenna be installed outside when the unit is used in weak radio wave area
or inside the ferroconcrete building. With the use of the long-wire antenna, it is possible to receive weak radio
signals that the supplied loop antenna cannot receive. The long-wire antenna can be installed by stringing a
PVC cable of about 5 – 10 m (16.5 – 33 ft) as illustrated below.
Notes
• Install the external antenna in an open field such as on the rooftop. Note that sufficient sensitivity cannot be
obtained if the antenna wire is set up between buildings.
• Keep the antenna at least 30 cm (1 ft) away from walls or metal objects that can interfere with radio signals.
