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. Press the [MENU/ESC] key to open the main menu. Use or to choose DEEP GAIN from page 1 of the menu. Choose Low, Medium, or High as appropriate. High provides the greatest degree of gain reduction against short range echoes. Press the [MENU/ESC] key to close the menu. Page 2 TRIP RESET This item resets trip distance to "0. " 1. Press the [MENU/ESC] key to open the main menu. SYSTEM MENU The System menu mainly consists of items which once set do not require frequent adjustment. You may display this menu by choosing SYSTEM MENU at page 2 of the main menu and pressing .
