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. This is useful when navigating to your favourite fishing location. To increase precision, the values are displayed in 0. 1 increments. You may display water temperature in degrees °C or °F. The depth of the bottom in feet, metres or fathoms. The speed of the boat in mph, knots or kph. 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. There are three different range modes; Top, Bottom, and All. 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. If Bottom is selected then an upper depth limit must also be entered. 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. [. . . ] Measure the voltage at the unit's power terminals. If it isn't: · the battery terminals or wiring on the terminals are corroded · the battery needs charging. · the wiring to the unit is defective 4. Check any fuses you may have placed in the line.
