1. CONNECTING ANTENNAS
· Change the position of the FM indoor antenna until you
get the best reception of your favorite FM stations.
· Place the AM loop antenna as far as possible from
the receiver, TV set, speaker cords and the AC
input cord and set it to a direction for the best
reception.
· If the reception is poor with the AM loop antenna,
an AM outdoor antenna can be used in place of
the AM loop antenna.
· A 75
outdoor FM antenna may be used to further
improve the reception. Disconnect the indoor
antenna before replacing it with the outdoor one.
