134 Audio System GENERAL INFORMATION Radio Frequencies and Reception Factors 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: 87.9-107.7, 107.9 MHz Distance and strength Terrain Radio reception factors The further you travel from an FM station, the weaker the signal and the weaker the reception. Hills, mountains, tall buildings, bridges, tunnels, freeway overpasses, parking garages, dense tree foliage and thunderstorms can interfere with the reception. When you pass a ground-based broadcast repeating tower, a stronger signal may overtake a weaker one and result in the audio system muting. Station overload CD and CD Player Information Note: CD units play commercially pressed 4.75-inch (12 centimeter) audio compact discs only. Due to technical incompatibility, certain recordable and re-recordable compact discs may not function correctly when used in Ford CD players. Note: Do not insert CDs with homemade paper (adhesive) labels into the CD player as the label may peel and cause the CD to become jammed. You should use a permanent felt tip marker rather than adhesive labels on your homemade CDs. Ballpoint pens may damage CDs. Please contact your authorized dealer for further information. Note: Do not use any irregularly shaped discs or discs with a scratch protection film attached. Always handle discs by their edges only. Clean the disc with an approved CD cleaner only. Wipe it from the center of the disc toward the edge. Do not clean in a circular motion. Do not expose discs to direct sunlight or heat sources for extended periods. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)
