[. . . ] The system consists of an LCD display unit and a depth transducer positioned in the water. The model FISH440 is also supplied with integrated boat speed and water temperature sensors. The automatic detection can locate and display the position of fish with three different size fish symbols. This feature can be disabled so that the LCD will display only the raw electronic signals. Experienced users can use this mode to extract even more information about the water and seabed conditions. Primary functions and quick operation introduction Turns the power ON and OFF · · Press for one second to turn the power ON Press and hold for three seconds to turn the power OFF Note Momentarily pressing the key removes or displays depth, speed and temperature data (depth only in the FISH400) from the upper left corner of the display. The format chosen is retained in memory when the power is switched off. Menu selection system Your fishfinder has many features that may be selected for adjustment. You may access all the menu screens by repeatedly pressing the key. Selects digital information to be displayed in the top left corner of the Fish Finder screen. Turns the backlighting ON or OFF · · Press once to turn the backlights ON Press again to turn the backlights OFF Decreases setting values in menus. This feature displays an intensity graph of the current echoes down the right hand side of the screen. The information can be used to help determine the type of bottom structure and the size of fish. The strength of the echo is proportional to size or number of pixels visible in the analogue section of the screen. This feature will help to determine the strength of the return echo from the bottom and therefore how hard or soft the bottom may be. Navigate Mode In this mode the depth, speed and temperature are displayed in large easily readable digits. To increase precision, the values are displayed in 0. 1 increments. You may display water temperature in degrees °C or °F. The log will display the total distance in the speed unit you have selected. The log total is automatically stored in memory when the power is switched off or removed but this value can be reset to zero (see SETUP menu). When either or all of the Fish (F), Shallow (S) or Deep (D) alarms are active they are displayed at the top left corner of the screen. 12 NAVMAN Fishfinder User Manual Range function Changing the mode of operation The range function allows you to control the depth range that is displayed on the LCD. If Top is selected then a lower depth limit value must also be selected. This mode locks the display to show only echoes from the surface of the water down to the lower depth limit you have selected. This means that the sea bed may not be shown if the water is deeper than the selected lower depth limit. This mode locks the display to show only echoes between the sea bed and the upper depth limit you have selected. The top of the water may not be shown if the water is deeper than the upper depth limit. This feature is like a ZOOM function, as it allows you to see the bottom contour and fish echoes above the bottom in greater detail. [. . . ] This menu enables you to customise the display of speed and temperature and to change the calibration setting of these features. Temperature units Temperature can be displayed in either °C or °F. Temperature calibration If the displayed temperature is known to be wrong then it can be adjusted using this function. Speed units of measure Speed can be displayed in either knots (KTS) miles per hour (MPH) or kilometres per hour (KPH). [. . . ]
