Radio ReceptionFrequency interference and static can occur duringnormal radio reception if items such as cell phonechargers, vehicle convenience accessories, and externalelectronic devices are plugged into the accessory poweroutlet. If there is interference or static, unplug the itemfrom the accessory power outlet.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 boost the power levelsduring the day, and then reduce these levels during thenight. Static can also occur when things like storms andpower lines interfere with radio reception. When thishappens, try reducing the treble on the radio.FM StereoFM signals only reach about 10 to 40 miles(16 to 65 km). Although the radio has a built-inelectronic circuit that automatically works to reduceinterference, some static can occur, especially aroundtall buildings or hills, causing the sound to fade inand out.XM™ Satellite Radio ServiceXM Satellite Radio Service gives digital radio receptionfrom coast-to-coast in the 48 contiguous United States,and in Canada. Just as with FM, tall buildings or hills caninterfere with satellite radio signals, causing the sound tofade in and out. In addition, traveling or standing underheavy foliage, bridges, garages, or tunnels may causeloss of the XM signal for a period of time.Cellular Phone UsageCellular phone usage may cause interference with thevehicle’s radio. This interference may occur when makingor receiving phone calls, charging the phone’s battery,or simply having the phone on. This interference causesan increased level of static while listening to the radio.If static is received while listening to the radio, unplugthe cellular phone and turn it off.3-128
