![174 3.3.10 In case of high waves CAUTION On short range scales, the setting of the sea surface clutter suppression should not be advanced to an extent that results in complete suppression of all clutter. Such a setting may suppress echoes from targets such as vessels or hazardous objects in addition to echoes from the waves and thus impair detection. When using the sea surface clutter suppression function, be sure that the sup-pression level is set at the optimum. When sea waves become high, echoes from the high waves (sea clutter) appear on the PPI screen making it difficult to see image of echoes from vessels or other objects. Sea clutter is increasingly prominent to the extent that its source is close to the ship. By using the [SEA] control function or the "automatic sea surface" function, sea surface clutter may be suppressed facilitating monitoring of the targets. Manual sea surface clutter suppressionManual sea surface clutter suppressionManual sea surface clutter suppressionManual sea surface clutter suppression (a) Turn the [SEA] control in the clockwise direction. As the control is turned in the clockwise direction, suppression of sea surface clutter increases.
