Entertainment Systems GENERAL AUDIO INFORMATION 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. 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. • Wipe discs from the center out. 53 2011 Expedition (exd) Owners Guide, 1st Printing USA (fus)
