33 - Audio equipment and telematics 01-01-2006 RADIO Notes on radio reception Your car radio is subject to phenomena which do not affect domestic radio sets. Both AM (MW/ LW) and FM reception are subject to various forms of interference. This is no reflection on the quality of the equipment, but is due to the nature of the signals and the way in which they are transmitted. On MW/LW, interference may be noticed when passing under high voltage power lines or bridges, or in tunnels. On FM, interference may be the result of increasing distance from the transmitter, deflection of the signals by obstacles (mountains, hills, buildings, etc.), or of being in an area which is not covered by a transmitter. Selecting radio mode Automatic station search Automatic volume correction This function enables the volume to be automatically adjusted depending on the level of noise produced by the speed of the vehicle. Press buttons H or I to switch the function on or off. Press button O. Press button O briefly to select wavebands FM1, FM2, FMast and AM. Briefly press button J or L to search for the station immediately above or below. By continuing to press the button in the direction selected, you will obtain continuous scrolling of the frequency. The scrolling stops at the first station found as soon as the button is released. If the TA traffic programme is selected, only stations broadcasting this type of programme are selected. Selecting a waveband Manual station search Press the "MAN" button. Briefly press button J or L to increase or decrease the frequency displayed. By continuing to press the button in the direction selected, you will obtain continuous scrolling of the frequency. The scrolling stops at the first station found as soon as the button is released. Pressing the "MAN" button again returns you to automatic station search. Manual storing of stations in the memory Select the station required. Press one of the buttons "1" to "6" for more than two seconds. The sound stops then becomes audible again, confirming that the station has been stored in the memory. Searching for a station occurs first in "LO" sensitivity (selection of the most powerful transmitters) during scanning of the waveband, then in "DX" sensitivity (selection of the weakest and most distant transmitters). To make a direct search in "DX" sensitivity, press button J or L twice. |
