ANTENNA CONNECTIONS
Each antenna should be connected to the designated terminals correctly, referring to the following diagram.
Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide
sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an
indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement.

Connecting the AM loop antenna
123
The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.
The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.
GND terminal
For maximum safety and minimum interference,
connect the GND terminal to a good earth ground.
A good earth ground is a metal stake driven into
moist earth.
Notes:
When connecting the indoor FM
antenna, insert its connector into the
FM ANT terminal firmly.
If you need an outdoor FM antenna to
improve FM reception quality, either
300-ohm feeder or coaxial cable may be
used. In locations troubled by electrical
interference, coaxial cable is preferable.
Orient so that the best
reception is obtained.
