[. . . ] It does this by equalizing echo presentation so that fish schools of the same size appear in the same density in both shallow and deep waters. The gain is adjusted automatically depending on the depth. The gain is low at short distance and getting back with increasing distance. High provides the greatest degree of gain reduction against short range echoes. Note that this function is operative when manual is selected on the GAIN knob. Smoothing: Smoothes echo presentation when enabled. Adjust the setting when echoes appear "spotty". TX Power: Interference may appear on the screen when an echo sounder having the same frequency as your own is being operated in the vicinity of your vessel. In this case, lower your TX power and contact the vessel to request them to reduce their TX power. The higher the numeric the greater the TX power. The "Auto" setting automatically adjusts TX power with depth. Note that this function is only operative when Fish Info and Fish Symbols in the Display menu are off. When Fish Info and Fish Symbols are on, the TX power mode is "Auto". Normally, the highest rate (10) is used. When in shallow waters second reflection echoes may appear between surface and actual bottom echo. The choice "S" means the ship's speed dependent mode, where the TX rate changes automatically with ship's speed. (Requires ship's speed input. ) Bottom area Border (below) [ENTER] : Set [MENU] : Cancel Bottom Area setting window 2. Use or to choose the border desired (Above or Below). White Line: Displays the leading edge of the bottom echo in white. This is useful for discriminating bottom fish from bottom. The setting range is 0 to 50 % in intervals of five. The larger the numeric, the wider the white line width. [. . . ] Use or to choose NMEA under System menu and press the ENTER key. NMEA NMEA0183 NMEA Port NMEA Output WAAS Setup TLL Output // [ENTER] [MENU] / : Ver 2. 0 : In/Out : Off : Off : TLL WAAS Setup Choose how to use the WAAS signal when connecting with a WAAS receiver, for example GP-320B. The message types (WAAS-00 to WAAS-27) are used as WAAS correction. Note: Currently, WAAS is only available in North America, and it is in the developmental stage in Europe and Japan. During the developmental phase the reliability and availability of the WAAS signal cannot be guaranteed. [. . . ]
