AMThe range for most AM stations is greater than for FM,especially at night. The longer range can cause stationfrequencies to interfere with each other. For better radioreception, most AM radio stations will boost the powerlevels during the day, and then reduce these levelsduring the night. Static can also occur when things likestorms and power lines interfere with radio reception.When this happens, try reducing the treble onyour radio.FM StereoFM stereo will give the best sound, but FM signals willreach only about 10 to 40 miles (16 to 65 km). Tallbuildings or hills can interfere with FM signals, causingthe sound to fade in and out.XM™ Satellite Radio ServiceXM™ Satellite Radio Service gives digital radioreception from coast-to-coast in the 48 contiguousUnited States, and in Canada (if available). Just aswith FM, tall buildings or hills can interfere with satelliteradio signals, causing the sound to fade in and out.In addition, traveling or standing under heavy foliage,bridges, garages, or tunnels may cause loss of XMsignal for a period of time. The radio may display NOXM SIGNAL to indicate interference.Cellular Phone UsageCellular phone usage may cause interference with yourvehicle’s radio. This interference may occur whenmaking or receiving phone calls, charging the phone’sbattery, or simply having the phone on. This interferenceis an increased level of static while listening to theradio. If static is received while listening to the radio,unplug the cellular phone and turn it off.Care of Your CDsHandle CDs carefully. Store them in their original casesor other protective cases and away from direct sunlightand dust. The CD player scans the bottom surfaceof the disc. If the surface of a CD is damaged, such ascracked, broken, or scratched, the CD will not playproperly or not at all. If the surface of a CD is soiled,take a soft, lint free cloth or dampen a clean, soft cloth ina mild, neutral detergent solution mixed with water,and clean it. Make sure the wiping process starts fromthe center to the edge.Do not touch the bottom side of a CD while handling it;this could damage the surface. Pick up CDs bygrasping the outer edges or the edge of the hole andthe outer edge.3-103
