8 Satellites GPS worldwide navigation The GPS system is 24 satellites orbiting the earth and broadcasting position and time signals. The GPS receiver analyses the signals from the closest satellites and calculates exactly where it is on earth. The accuracy is typically better than 10 m (33 ft) for 95% of the time.
9 Echosounder fishfinding: Introduction ! CAUTION ! WARNING Use the automatic CruisingDANGER or Fishing modes when learning to use the unit or CAUTION when travelling at speed. 9-1 Using the unit The unit uses a echosounder transducer attached to the hull. The transducer generates an ultrasonic pulse (sound that is above the hearing range of the human ear), which travels down towards the bottom at a speed of about 1463 m/s (4800 ft/s), spreading out into a cone shape.
9-2 Interpreting the display The echosounder windows do not show a fixed distance travelled by the boat; rather, they display a history, showing what has passed below the boat during a certain period of time. The history of the echosounder signal shown depends the depth of the water and the scroll speed setting. In shallow water, the echoes have a short distance to travel between the bottom and the boat.
WARNING DANGER • Clarity of water. Particles or air in the water reduce the strength of the echo. CAUTION • Composition or density of the object or bottom. Planing hulls at speed produce air bubbles and turbulent water that bombard the transducer. The resulting ultrasonic noise may be picked up by the transducer and obscure the real echoes. Bottom types Mud, weed and sandy bottoms tend to weaken and scatter the echosounder pulse, resulting in a weak echo.
Shadows Shadows are created around areas where the ultrasonic beam cannot ‘see’. These areas include hollows on the bottom or beside rocks and ledges, where the strong echoes returned off the rocks obscure the weak echoes of the fish and may also create a double bottom trace. See following for an example of the echosounder window in such an environment. A double bottom trace is shown on the window.
This frequency is useful for getting a deep, wide overview of the area so that any areas of interest can be identified and then examined in detail with the 200 kHz frequency. When to use Mixed The Mixed frequency combines the 200 kHz and the 50 kHz echoes on one echosounder window, filling in detailed echoes in the center of the echosounder cone.
Comparison of the same fish scenario shown at different frequencies: 1 minute ago 30 seconds ago 50 kHz display 200 kHz display 200/50 kHz display Mixed display Simrad NX40/45 Installation and Operation Manual Now 41
9-4 Fish detection and display Where to find fish Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the 50 kHz or 50/200 kHz frequency window to find these features, then look for fish by passing over the feature slowly several times using the Zoom window. If there is a current, the fish will often be found downstream of the feature. A weak fuzzy band may appear between the bottom trace and surface.
water tend to show as randomly stacked areas of color. • Wave motion may result in distorted fish arches. 9-5 Range Range is the vertical depth shown on the unit echosounder window. For example, if the range is 100 m, then the echosounder window shows depths between 0 and 100 m. The range is shown at the bottom, right corner of a echosounder window. The unit has two range modes: • Auto: The unit adjusts the range automatically so that the bottom of the water is always shown at the bottom of the window.
The gain window To display or change the current settings for gain Select a echosounder window > > Threshold Changing mode The unit has three operating modes, In Cruising and Fishing modes, the unit automatically adjusts gain and threshold for good performance. In manual mode, you can hand adjust the settings. To change the mode from the Gain window Mode > Fishing or Cruising or Manual When you select Manual, the unit reverts to your last manual settings.
10 Echosounder To show the echosounder window > echosounder There are five kinds of echosounder window. To use a window > echosounder splits Then select the type of window to use: • No split: echosounder history window at a single or mixed frequency. • Split zoom: echosounder history plus a zoomed section. • Full screen zoom. • Split bottom: echosounder history plus a bottom trace in a zoomed section. • Split 50/200: echosounder histories at 50 and 200 kHz.
10-1-1 Extended history mode To review an old echosounder echo The time since the echoes shown on the screen were recorded is shown at the bottom of the screen. To return to the most recent echo The digital depth shown is always the current depth, even in extended history mode. The History Position Bar indicates the age of the most resent echo on the screen, and the position of the current screen in the recorded history.
Bottom lock To turn Bottom lock on or off > Bottom lock > On or Off If Bottom lock is on, pressing will turn it off. 10-3 Echosounder split window A Zoomed bottom signal B Sounder history The window shows the echosounder history on the right and the bottom signal as a flat trace in the center of the zoom section on the left. The flat trace make it easy to compare the echo strengths shown in the bottom signals. This can help to identify the type of bottom and objects close to the bottom.
Use the A-Scope while adjusting the gain and threshold settings manually. Setting gain and threshold It is convenient to use the A-scope window when adjusting gain and threshold manually. Follow this procedure to adjust gain and threshold for normal circumstances: • Switch to a echosounder window. If necessary, press to adjust range so that the bottom is shown. • If necessary, select the echosounder frequency , select to adjust the settings for. Press Frequency and select 200 kHz or 50 kHz.
11 Gauges window The Gauges window shows boat data, such as water speed, as analog gauges. To select the Gauges window > More > Gauges Before using the Gauges window, set Speed range, Max RPM and Max fuel flow. To select a layout from the Gauges window > Layout The Gauges window can show one of four gauge layouts. Changing data shown in the gauge layout > Gauge setup > > > > You can change the data shown on each gauge in a layout.
12 Data window The data window has large numeric data fields and a graph of depth and water temperature if available.
13 Fuel functions and display The Fuel functions require optional petrol/gasoline or SmartCraft fuel sensors to be installed and set up. 13-1 What the fuel computer does Each engine has a flow sensor installed to measure the engine’s fuel flow. The NX40/45 use these flows, together with boat speed and engine RPM if available to estimate the fuel remaining in the tank(s), fuel used, range and fuel economy. This data is shown on the fuel display. You can: • display the fuel used during a trip.
Used The fuel used during a trip. On a multi-engine boat, the data for the port engine is on the left of the display. When you want to start measuring how much fuel is used, go to the Fuel display. To clear fuel used in a single-engine boat > Clear used To clear fuel used in a multi-engine boat > Clear used > Port or Starboard or both The fuel used by each engine and the total fuel used are shown. Fuel flow The fuel flow for the engine(s).
Note: Underfloor fuel tanks are often difficult to refill to the same level twice, due to air pockets. With underfloor fuel tanks: • Trim the boat to the same angle in the water each time you follow procedure A. • Mostly use procedure B below when adding fuel, but completely fill the tank and follow procedure A about every tenth time you add fuel. B - Part fill a tank When you part fill a tank Write down how much fuel you add. Change the number.
13-4 Low fuel alarm To set a low fuel alarm > > Fuel > Setup tanks > Tank alarm Select and enter a fuel level to trigger the low fuel alarm; or enter zero to disable the alarm. On a multi-tank boat, select the tank to set the alarm for. When a low fuel alarm is set, the alarm’s fuel level is shown on the fuel display tank levels as a red bar. The alarm can also be set using the Alarms setup menu.
13-5-2 Water speed and ground speed Example 1: A paddlewheel sensor and a pitot sensor measure water speed, the boat speed through the water. A GPS measures ground speed, the boat speed over the bottom of the water. If there is a current, then these speeds will be different, and the log, trip log, economy and range will be different, as shown below.
consumption curves for different boat, weather or sea conditions. Compare these with your first curve to see how your boat’s performance changes with conditions. Making a curve • Start running the boat in a straight line. • Choose a speed source for the curve. Normally choose Water speed to measure the boat’s potential performance. • Press twice, then select Fuel. • Select Fuel consumption curve, then select New.
13-6-3 Using fuel consumption curves Deleting a curve > > Fuel > Fuel consumption curve > Name > select the name of the curve to delete > Delete Selecting a curve You must make a fuel consumption curve before you can use it. > Fuel consumption curve >select the curve right if necessary to select On the fuel display, press Fuel curve and display the fuel consumption curve. Note • On a multi engine boat, keep the RPM of all engines similar while using a curve.
13-7 Calibration Calibrate petrol/gasoline fuel flow sensors during installation, or if the fuel readings seem inaccurate and the other troubleshooting suggestions do not help (see Appendix B troubleshooting). Note • SmartCraft fuel sensors are factory calibrated and should never need recalibrating. • On a multi engine boat, calibrate each engine’s sensor. This can be done at the same time with a portable tank for each engine or at different times using one portable tank.
14 Tides window ! CAUTION ! WARNING DANGER The tides window is available on Chart cards. The tides window shows tide information at a tide station for the selected date. CAUTION The tides window requires the local time offset to be set to work correctly.

16 AIS AIS is short for Automatic Identification System. The International Convention for Safety of Life At Sea (SOLAS) requires all vessels greater than 300 tons and all passenger vessels to be equipped with AIS Transponders. All vessels equipped with AIS permanently broadcast via one or more of the two dedicated VHF channels. This transmission may include information about the vessels MMSI-number, its call sign, name, position, course, heading, speed, rate of turn and type of vessel.
When the cursor is placed over an AIS vessel for at least two seconds, a data box appears at the bottom of the window with information about the AIS vessel. For complete AIS information over AIS vessel > Press either or . to clear the information. 16-2 Dangerous Vessels The NX40/45 calculates the time of closest point of approach (TCPA) and closest point of approach (CPA) for each AIS vessel. This is used to determine potential dangerous vessels.
Sorting Vessels > Sort Safety msgs (rx) Safety msgs (rx) are broadcasted messages received by the AIS receiver. This window displays the date and time of message received, MMSI of AIS vessel that broadcasted the message, and the message itself. Safety msgs (rx) list will store up to 10 messages. The oldest message is replaced when the list is full.
17 SmartCraft Operation Mercury’s SmartCraft™ is an engine management system used for compatible Mercury engines. If you have a Mercury engine, you may want to display quality real-time data to your NX40/45 series unit. Note: SmartCraft Gateway is a peripheral device that can be purchased from your Simrad dealer. When connecting SmartCraft to an NX40/45 series unit, you need to enable SmartCraft functions in the display menu. 17-1 Turning SmartCraft on: 1. From your keypad, press SETUP (or MENU twice).
17-3 Key Features Depending on the engine and display, below are some key features that SmartCraft can perform when connected; these include: Data Displays • Engine performance and tank level displays. Troll Control • Automatically maintains a set engine idle Revs per minute (RPM) or idle boat speed. Trim Indicator • Displays the trim angle when engine trim is adjusted. Alarms • SmartCraft engine fault alarms • Engine fault list of active SmartCraft engine fault alarms • Engine fault history; e.g.
• If the boat has twin engine, the red needle or number shows port data, green shows the starboard data. • The gauges can be set up to be analog (dial) or digital (number). 17-3-2 Tank level displays The tank level display shows the levels from the optional level sensors in one or two tanks per engine, containing either fuel, oil, water or waste. Refer to the Navico installation manual for further information. • Each tank must be setup and calibrated.
Notes: • The range of engine idle RPM adjustable available for both RPM and speed mode depends on engine type.

18 Radar Radar is the Radio Detection And Ranging system. Radar functions require an optional Simrad radar system to be installed. Three radar systems are available; 2 kW, 4 kW, or 6 kW. When the radar is operating, the scanner transmits powerful microwave radio pulses which are reflected back from any solid objects such as land masses or other boats. These objects are called targets and are shown on the radar window.
18-2 Radar modes There are four radar modes: • Disabled. This saves on power consumption and magnetron usage. If the radar is disabled, it has to warm up and enter standby mode before it can start transmitting. • Warming. The radar on and is warming up. This can take up to 90 seconds, depending on your scanner type. • Standby. The radar is on and is warmed up. It is ready to start transmitting immediately. • Transmitting. The radar is actively sending and receiving microwave radio pulses.
18-6 Adjusting the quality of the radar window Common problems that can degrade the quality of the radar window include: • sea clutter • rain clutter • false echoes (sometimes called ghost echoes) and background noise • side lobe patterns (false echoes that appear as an arc or a broken arc) • shadows (blind spots) • multiple echoes off the same object • incorrect threshold setting If the radar is installed at a suitable height and in a suitable location on your boat, side lobe patterns and shadows (blind sp
18-6-2 Changing the gain level Use the radar gain level to adjust the sensitivity of the radar receiver. Ideally, the radar gain level should be set so that background noise is just visible on the radar window. If the radar gain level is too low, weak echoes won’t be shown. If the radar gain level is too high, strong echoes will be difficult to see amongst the large amount of background noise. (If the radar Gain Mode is set to Auto and you adjust the gain level manually, the Gain Mode is changed to Manual.
If you are in Range Rider mode when you adjust the sea clutter level, the sea clutter mode does not change to manual but the setting is stored and used automatically whenever you use the same range again. To change the sea clutter level > Adjust Radar > Sea Clutter Level > 18-6-5 Changing the rain clutter Rain clutter consists of random dots that can merge into badly-defined echoes on your radar screen. The random signals are returned from rain, hail, sleet, or snow and can result in a confusing display.
• Off. No echo expansion. • 1. Targets expanded x 2. • 2. Targets expanded x 3. 18-8 Turning the target trails on or off If you turn the target trails on, each target leaves a 30 second trail on the radar screen. You cannot change the length of the target trail. If you turn the target trails off, the targets do not leave trails. Note that if the radar motion mode is set to true, stationary targets won’t leave a trail.
• Select VRM/EBL then 1 (VRM/EBL 1) or 2 (VRM/EBL 2). to show the VRM and EBL on the • Set Enable to radar window (or to hide them). • Select EBL reference if you want to change the EBL bearing reference.

covers a 1.5 dB signal range. The 8 color palette displays less detail, and each color covers a 3 dB signal range. Interference filter No filter, normal setting. Filters the echo signal to remove spiky interference such as engine noise or echosounders on nearby boats. Noise filter Averages the echo signal to remove rapid changes. Select Medium or High to give a smoother bottom trace–this may help to detect a deeper bottom; however these settings may also remove fish echoes.
Head up means that the radar image rotates underneath your boat, so the direction in which you are heading is pointing to the top of the radar screen. You can easily compare the visual view in front of your boat with the radar screen. Course up works only when COG data or heading data from a heading sensor is available and there is an active route.
There are four choices: Off. Interference rejection is off. Low operates the interference rejection at minimum strength. Medium operates the interference rejection at medium strength. High operates the interference rejection at maximum strength. This setting can make it more difficult to detect some targets and radar beacons. Palette Select the color scheme for the radar window. Digit size The range of the radar is shown on the radar window; for example 1/16.
19-4-1 Setup > Radar > Installation > Radar > Installation Note: This option is shown only when the radar is enabled. Park position If your radar has an open array and you take it out of enabled mode, the open array continues to rotate for a short distance before it finally stops. The stop position is known as the park position. You can adjust the angle of the parking position so that the open array will always stop at your preferred position; for example, facing the bow.
To adjust the zero range setting: • Position your boat about 45 to 90 m (50 to 100 yards) away from and parallel to a straight-walled jetty or similar feature. • Adjust the gain setting if necessary, so that a reasonably good image of the jetty echo is shown on the radar window. At this stage, the jetty echo may appear to be bent. • Select Zero range then use the arrow keys to adjust the zero range setting until the jetty echo appears as a straight line on the radar window.
19-6 Setup > Fuel > Fuel Note: Fuel functions require fuel flow sensors to be installed. Source Select the fuel flow sensors to use if the boat has more than one set of fuel sensors. Normally select Auto. Num engines Set the number of engines, or select 0 to disable the fuel functions. If there are two engines they are called port and starboard. Num tanks Set the number of fuel tanks. If there are two tanks they are called port and starboard.
Speed source If both water speed and ground speed are available, select which to use for fuel calculations. Max fuel flow The maximum fuel flow from a fuel tank to be shown on an analog fuel flow gauge. 19-7 Setup > Track > Track Tracking records and displays the boat’s course on the chart). Ten different tracks can be recorded. Record Off: The unit stops recording a track. 1 to 10 (select a track number): The unit starts recording the boat’s course into the selected track.

Show Dangerous Only Show only vessels that have a TCPA/CPA below the trigger values. This filter will override any other filter option. Dangerous Vessel Alarm When enabled an alarm will activate when both the TCPA and CPA are less than the trigger values. Note: Even when this setting is disabled the dangerous vessels will still be indicated on the chart. TCPA Limit Set the Time of Closet Point of Approach limit. CPA Limit Set the Closet Point of Approach limit.
A Transducer; depths measured below here You can display the alarm status in the data header. The alarm status shows the symbol for each alarm that is on. The symbol is normally black and turns red if the alarm triggers.
19-13 Setup > Calibrate > Calibrate Speed This calibrates the speed from a paddlewheel sensor connected to the unit. Calibration may be required because different hull shapes have different flow characteristics. Note: for accurate calibration, The speed from a GPS receiver should be greater than 5 knots, and the speed from another paddlewheel transducer should be between 5 and 20 knots. Best results are achieved in calm conditions where there is minimal current (best at high or low tide).
Temperature filter Water turbulence and currents cause the water temperature to fluctuate slightly. To give stable readings, the unit calculates these values by taking several measurements and averaging them. Set the Temperature filter to the lowest value which gives stable readings. The range is 1 to 30 seconds or Off (0). Keel Offset A depth transducer measures depths below where the transducer is mounted on the boat, usually the bottom of the boat.

2-3 Unit position different from same position on local charts: • Unit in simulate mode. Turn simulate mode off. • Fuel transducers wear out over time and should be replaced after every 5000 litres of fuel. 3-2 Flow indicates no fuel or low fuel: the • Check that the number of engines is set to 1. • Map shift has been applied wrongly. Clear map shift, then reapply if necessary. • Check that the fuel cable connectors are securely plugged in and the collar is locked in place.
the two magnets in the paddlewheel are still in place. B-4 echosounder fishfinding problems 4-1 The unit operates erratically: • Check that the transducer does not have debris (e.g. weed, plastic bag) caught around it. • The transducer may have been damaged during launching, running aground or while underway with debris etc. If the transducer has been impacted, it may have been kicked up on the bracket. If it is not physically damaged, reset the transducer back to its original position.
the boat is reversed. The transducer must be mounted in a smooth flow of water in order for the unit to work at all boat speeds. • Electrical noise from the boat’s motor can interfere with the unit. Try some suppression spark plugs. 4-5 There is a double bottom trace shown: • The boat may be in an area that generates shadows. • In shallow water, the echoes may bounce. Reduce the gain setting and/or reduce the echosounder pulse power. • Decrease the Range.
