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 adjusting the treble control counterclockwise to reduce treble response. 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. The radio has an FM Diversity reception system, which employs two antennas if so equipped. One is a rod type antenna; the other is an antenna printed on the window. This system automatically switches to the antenna which is receiving less noise. For additional information, see "Antenna" later in this section. signals are also subject to interference as they travel from transmitter to receiver. Fading: Occurs while the vehicle is passing through freeway underpasses or 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. are peeling and loose. If used, the label could jam in the player. ¼ If a cassette has loose tape, insert a pencil through one of the cassette hubs and rewind the tape firmly around the hubs. Loose tape may cause tape jamming and wavering sound quality. ¼ Over a period of time, the playback head, capstan and pinch roller may collect a tape coating residue as the tape is played. This residue accumulation can cause weak or wavering sound, and should be removed periodically with a head cleaning tape. If the residue is not removed periodically, the player may need to be disassembled for cleaning. AUDIO OPERATION PRECAUTIONS Cassette player ¼ To maintain good quality sound, NISSAN recommends using cassette tapes of 60 minutes or shorter in length. ¼ Cassette tapes should be removed from the player when not in use. Store cassettes in their protective cases and away from direct sunlight, heat, dust, moisture and magnetic sources. ¼ Direct sunlight can cause the cassette to become deformed. The use of deformed cassettes may cause the cassette to jam in the player. ¼ Do not use cassettes with labels which 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 4-12 Heater, air conditioner and audio systems
