Corolla_MATRIX_Navi_U (L/O 0208) Car audio system operating hints (g) If the player malfunctions If the player does not operate, check that the disc surface is not soiled or damaged. If the disc is O.K., the following causes are possible. NOTICE To ensure the correct audio system operation: z Be careful not to spill beverages over the audio system. z Do not put anything other than a Compact Disc into the slot. z The use of cellular phone inside or near the vehicle may cause a noise from the speakers of the audio system which you are listening to. However, this does not indicate a malfunction. RADIO RECEPTION Usually, a 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. The farther you are from a station, the weaker its signal will be. In addition, reception conditions change constantly as your vehicle moves. 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. D The temperature of the player's internal mechanism may be raised because of high external temperature. Remove the disc from the player to cool it.

D The temperature of the player's internal mechanism may be raised because of high external temperature. Remove the magazine from the player to cool it.
