ANTENNA CONNECTIONS
● Each antenna should be connected to the designated terminals correctly, referring to the following figure.
● 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
* 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 grounding. A good grounding is a
metal stake driven into moist earth. Notes
● When connecting the indoor
FM antenna, make sure that
the grooved part of the
connector hole is facing
downward.
● If you need an outdoor FM antenna to improve FM reception
quality, either a 300-ohm feeder or a coaxial cable may be
used. In locations troubled by electrical interference, a
coaxial cable is preferable.
