If there is interference or static,unplug the item from 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 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 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.4-115
