Fade and drift: As your vehicle moves away from a station transmitter, the signals will tend to fade and/or drift. Static and flutter: During signal interference from buildings, large hills or due to antenna position, usually in conjunction with increased distance from the station transmitter, static or flutter can be heard. This can be reduced by lowering the treble setting to reduce the treble response. SAA0306 in areas with many tall buildings. It can also occur for several seconds during ionospheric turbulence even in areas where no obstacles exist. Static: Caused by thunderstorms, electrical power lines, electric signs and even traffic lights. Satellite radio reception: When the satellite radio (if so equipped) is first installed or the battery has been replaced, the satellite radio may not work properly. This is not a malfunction. Wait more than 10 minutes with satellite radio ON for satellite radio to receive all of the necessary data. The satellite radio mode will be skipped unless an optional satellite receiver and antenna are installed and an XM or SIRIUSTM satellite radio service subscription is active. Satellite radio is not available in Alaska, Hawaii and Guam. Satellite radio performance may be affected if cargo carried on the roof blocks the satellite radio signal. If possible, do not put cargo near the satellite antenna. FM radio reception: Range: FM range is normally limited to 25 to 30 miles (40 to 48 km), with monaural (single channel) FM having slightly more range than stereo FM. External influences may sometimes interfere with FM station reception even if the FM station is within 25 miles (40 km). The strength of the FM signal is directly related to the distance between the transmitter and receiver. FM signals follow a line-of-sight path, exhibiting many of the same characteristics as light. For example they will reflect off objects. Multipath reception: Because of the reflective characteristics of FM signals, direct and reflected signals reach the receiver at the same time. The signals may cancel each other, resulting in momentary flutter or loss of sound. AM radio reception: AM signals, because of their low frequency, can bend around objects and skip along the ground. In addition, the signals can be bounced off the ionosphere and bent back to earth. Because of these characteristics. AM signals are also subject to interference as they travel from transmitter to receiver. Fading: Occurs while the vehicle is passing through freeway underpasses or 4-30 Monitor, climate, audio, phone and voice recognition systems
