Entertainment Systems RADIO FREQUENCIES AM and FM frequencies are established by the Federal Communications Commission (FCC) and the Canadian Radio and Telecommunications Commission (CRTC). Those frequencies are: AM - 530, 540-1700, 1710 kHz FM- 87.7, 87.9-107.7, 107.9 MHz RADIO RECEPTION FACTORS There are three factors that can affect radio reception: • Distance/strength: The further you travel from an FM station, the weaker the signal and the weaker the reception. • Terrain: Hills, mountains, tall buildings, power lines, electric fences, traffic lights and thunderstorms can interfere with your reception. • Station overload: When you pass a broadcast tower, a stronger signal may overtake a weaker one and play while the weak station frequency is displayed. CASSETTE/PLAYER CARE Do: • Use only cassettes that are 90 minutes long or less. • Tighten very loose tapes by inserting a finger or pencil into the hole and turning the hub. • Remove loose labels before inserting tapes. • Allow tapes which have been subjected to extreme heat, humidity or cold to reach a moderate temperature before playing. • Clean the cassette player head with a cassette cleaning cartridge after 10-12 hours of play to maintain good sound/operation. Don't: • Expose tapes to direct sunlight, extreme humidity, heat or cold. • Leave tapes in the cassette player for a long time when not being played. CD/CD PLAYER CARE Do: • Handle discs by their edges only. Never touch the playing surface. • Inspect discs before playing. Clean only with an approved CD cleaner and wipe from the center out. 42 2005 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
