AUDIO/VIDEO SYSTEM FM Fading and drifting stations - Generally, the effective range of FM is about 40 km (25 miles). Once outside this range, you may notice fading and drifting, which increase with the distance from the radio transmitter. They are often accompanied by distortion. Multi−path - FM signals are reflective, making it possible for two signals to reach your antenna at the same time. If this happens, the signals will cancel each other out, causing a momentary flutter or loss of reception. Static and fluttering - These occur when signals are blocked by buildings, trees, or other large objects. Increasing the bass level may reduce static and fluttering. Station swapping - If the FM signal you are listening to is interrupted or weakened, and there is another strong station nearby on the FM band, your radio may tune in the second station until the original signal can be picked up again. AM Fading - AM broadcasts are reflected by the upper atmosphere - especially at night. These reflected signals can interfere with those received directly from the radio station, causing the radio station to sound alternately strong and weak. Station interference - When a reflected signal and a signal received directly from a radio station are very nearly the same frequency, they can interfere with each other, making it difficult to hear the broadcast. Static - AM is easily affected by external sources of electrical noise, such as high tension power lines, lightening, or electrical motors. This results in static. CARING FOR YOUR CD CHANGER, DVD PLAYER AND DISCS D Your CD changer is intended for use with 12 cm (4.7 in.) discs only. D Extremely high temperatures can keep your CD changer and DVD player from working. On hot days, use the air conditioning to cool the vehicle interior before you use the changer and player. D Bumpy roads or other vibrations may make your CD changer and DVD player skip. D If moisture gets into your CD changer and DVD player, you may not play even though they appear to be working. Remove the disc from the changer and player and wait until it dries. CAUTION CD changers and DVD players use an invisible laser beam which could cause hazardous radiation exposure if directed outside the unit. Be sure to operate the changers and players correctly. 242
