Uniden SOLARA DSC English Owners Manual - Page 10

Engine Noise Suppression Interference from the noise generated by the electrical systems of engines is sometimes a problem with radios. The SOLARA DSC has been designed to be essentially impervious to ignition noise and alternator noise. However, in some installations it may be necessary to take measures to further reduce the effect of noise interference. All DC battery wires, antenna lead, and accessory cables should be routed away from the engine and engine compartment, and from power cabling carrying high currents. In severe cases of noise interference, it may be necessary to install a noise suppression kit. Contact your Uniden Dealer for more information. Antenna Considerations A variety of antennas are available from a number of quality suppliers. It is recommended you draw upon the advice of your Uniden dealer in determining a suitable antenna for your vessel and range requirements. In general, communication range is increased by using a high-gain antenna placed as high as possible above the water line. Antennas should be located away from metal objects. Antennas should not have excessively long coaxial feed cables. Antenna Selection and Installation SOLARA DSC has been designed to accomodate all of the popular marine VHF antennas. However, the selection and the installation of the antenna is the responsibility of the user or installer. The FCC has determined that excessive radiation poses a health risk to people near radio transmitting antennas. Therefore, the antenna used with this radio should be installed using the following guidelines to insure a suitable distance between the antenna and persons close by. Small whip antennas (3 dB) or smaller should be installed keeping at least three feet separation distance between the radiating element and people. Larger antennas (6 dB or 9 dB) should be installed keeping at least a six feet separation distance. No person should touch the antenna or come into the separation distance when the radio is transmitting. 8
