AIR CONDITIONING AND AUDIO (h) If the player malfunctions If "WAIT" appears on the display, audio signals of the disc cannot be read or the system has trouble. Push the "CD" button once again. If the player does not operate, check that the disc surface is not soiled or damaged. If the disc is O.K., the following two causes are possible.  Condensation may have occurred on the internal mechanism of the automatic changer. Open the cover to let the air circulate.  The temperature of the player's internal mechanism is raised because of high external temperature. Remove the magazine from the player to cool it. If the player still does not operate, take it to your Lexus dealer. Here are some common reception problems that probably do not indicate a problem with your radio. 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. Car audio system operating hints Radio reception Usually, the problem with radio reception does not mean there is a problem with your radio - it is just the normal result of conditions outside the vehicle. For example, nearby buildings and terrain can interfere with FM reception. Power lines or telephone wires can interfere with AM signals. And of course, radio signals have a limited range, and the farther you are from a station, the weaker its signal will be. In addition, reception conditions change constantly as your vehicle moves. 120
