When you have finished, click the BACK button. 79 The sea clutter control can be set to Auto-Harbor (default), Auto-Offshore, or manual mode. In Auto-Off-shore mode, the radar optimizes its settings to account for the effects of sea clutter. In harbors and close proximity to land, different auto settings may be necessary to account for land clutter. To avoid losing small targets, set the sea clutter control to Auto-Harbor mode. If you set the sea control to manual mode, be sure you adjust the settings to ensure that all close small targets are visible. FTC You can use the Fast Time Constant (FTC) function to remove areas of clutter at a distance from your boat. It should be used in conjunction with the RAIN function to obtain the best results. When the FTC function is turned up, only the leading edge of large (rain clutter) echoes is shown, while the effect on smaller (boat) echoes is slight. This means that you can also use the function on shorter ranges to distinguish between two very close echoes on the same bearing, which may otherwise merge and appear as one echo. With the FTC function set high, the receiver is made less sensitive, and there is a reduction of background noise and fill-in reTurns from land and large targets. You should therefore set the control to low (or Off) when its use is not required. Gain mode The gain control adjusts the level of the display of signals received from the scanner; and is the equivalent to the volume control on a radio. The gain control can be set in either Auto or Manual mode. In auto mode, the radar self optimizes its settings. In harbors or close proximity to land, different auto settings may be necessary to compensate for the effects of land clutter. In manual mode, you must adjust the settings to ensure that all close small targets are visible, and you should check it every time you change the range scale. On long range settings, the gain should be set to give a slight speckle in the background of the radar picture. On shorter ranges, you may want to reduce the gain slightly to reduce the speckle and improve target definition. Do not set the gain too low, or you may miss small or weak targets.
