Radio Reception & Antenna Care & Maintenance Even the best quality AM & FM tuners may have some difficulty receiving analog AM and FM signals. Here are some tips for getting the best possible radio reception from your I-Sonic Entertainment Digital Audio System. AM Radio The I-Sonic has an external AM loop antenna. Be sure to connect the wire marked in white to the white marked terminal and the wire marked in black to the black marked terminal. Move the antenna around to find the best reception position. If your radio is located in a metal frame building, there may be no reliable way to receive AM radio broadcasts. FM Radio The quality of FM reception is affected by many factors such as distance, location of the radio transmission tower and your proximity to large buildings, mountains and other large objects. You will get better reception when the radio/antenna is placed high in the house. Rural Conditions If you live far from radio transmitters you may not get the results you want with any in-door antenna. The very best option is an outdoor directional antenna specifically designed for FM with a rotor for aiming the antenna. If you already have a roof TV antenna you can tap into that although a specially designed FM antenna is better. Cable Some cable TV companies broadcast FM signals on their cable systems. Check with your local cable provider before attempting to hook up your I-Sonic's FM antenna jack to your cable system. Maintaining Your I-Sonic Use only a soft dry cloth to clean the system. Do not use any liquid cleaning solutions, solvents, chemicals, alcohol, ammonia, or abrasives. Clean grilles with compressed air. Clean iPod dock with compressed air. 18 Polk Audio Customer Service 800-377-7655 (Outside USA & Canada: 410-358-3600) I-Sonic: Radio Reception & Antenna / Maintenance
