System Connections
• Do not plug the AC input cord into the wall AC outlet until all connections are completed.
• Be sure to connect the white RCA pin cords to the L(left) and the red RCA pin cords to the R(right) jacks when making audio
connections.
• Change the position of the FM indoor antenna until you get the best reception of your favorite FM stations.
• A 75 Ω outdoor FM antenna may be used to further improve the reception.
Disconnect the indoor antenna before replacing it with the outdoor one.
• 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.
• Make connections firmly and correctly. If not, it can cause loss of sound, noise or damage to the receiver.
• If the electricity fails or the AC input cord is left unplugged for more than 2 weeks, the memorized contents will be cleared.
Should this happen, memorize them again.
