Simrad NX40/45 Installation and Operation Manual2

Warning

It is your sole responsibility to install and use the instrument and transducer(s) in a manner that will not cause accidents, personal injury or property damage. Always observe safe boating practices.

The choice, location, and installation of transducers and other components of the system are critical to the performance of the system as intended. If in doubt, consult your Simrad dealer.

To reduce the risk of misusing or misinterpreting this instrument, you must read and understand all aspects of this Installation and Operation Manual. We also recommend that you practice all operations using the built-in simulator before using this instrument at sea.

Global Positioning System: The Global Positioning System (GPS) is operated by the US Government which is solely responsible for its operation, accuracy and maintenance. The GPS is subject to changes which could affect the accuracy and performance of all GPS equipment anywhere in the world, including this instrument.

Electronic Chart: The electronic chart used by this instrument is an aid to navigation

designed to supplement, not replace, ofcial government charts. Only ofcial government

charts supplemented by notices to mariners contain the information required for safe and prudent navigation. Always supplement the electronic information provided by this instrument with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further.

AIS: The AIS features on this chart-plotter are designed as a safety aid only and do not guarantee safety at sea. AIS transmission is mandatory on some, but not all, vessels. You should check your local laws and regulations for requirements in your area. As a result of different legal requirements, different vessel sizes and uses, you should not assume that your AIS equipped chart-plotter will show the location of ALL vessels in your area. Careful prudence, judgement, and safe navigation practices should always be exercised. AIS should be used to complement radar, but AIS is not a substitute for radar.

Sounder performance: The accuracy of the echosounder depth display can be affected by many factors, including the type and location of the transducer and water conditions. Never use this instrument to gauge depth or other conditions for swimming or diving.

Fuel data: Do not rely on this instrument as the sole source of information about fuel available onboard. You must supplement this instrument’s fuel data with visual or other checks of the fuel available. This is necessary because possible operator errors, such

as forgetting to reset the fuel used when lling the tank or running the engine with

this instrument not switched on, can render this instrument inaccurate. Fuel economy can change drastically depending on boat loading and sea conditions. Always carry adequate fuel onboard for the intended trip, plus a reserve to allow for unforeseen circumstances.

Simulate mode: Never have simulate mode on when you are navigating on the water. Failure to adhere to these warnings may lead to death, serious injury or property

damage. Simrad disclaims all liability for installation or use of this product that causes or contributes to death, injury or property damage or that violates any law.

Overview2

1-1 Overview

The Simrad NX40/45 is a rugged, highly integrated

marine chartplotter and shnder. It is easy to use and

has a high resolution color display. Complex functions can be performed with only a few key presses, taking the hard work out of boating.

The available functions depend on the optional sensors and instruments that are installed:

The Video window requires the NX40/45 to receive • video from a compatible source, such as a camera.

Fuel functions require fuel sensors to be installed.• SmartCraft engine functions require a SmartCraft •

system to be installed. For information on using SmartCraft, see the SmartCraft Gateway Installation and Operation Manual.

The NX40/45 can send data to other instruments, • such as an autopilot, and receive data from other instruments.

Radar functions require an optional Simrad radar • system to be installed.

AIS functions require an optional AIS receiver to be •

installed. For information on installation options. This manual describes how to install and operate the

NX40/45. Special terms are explained in Appendix C. For more information on this instrument and other Simrad products, go to our website, www.simrad-yachting.com.

1-2 Cleaning and maintenance

The screen is covered by a proprietary anti-reection

coating. To avoid damage, clean the screen only with a damp cloth and mild detergent when dirty or covered in sea salt. Avoid abrasive cleaners, petrol or other solvents. If a plug-in card gets dirty or wet, clean it with a damp cloth or mild detergent.

Navigation: Chart4

3-1 Introduction to navigating

The unit has two ways of navigating, going straight to a point or following a route.

3-1-1 Navigating to a point

When the unit is navigating to a point, the chart and highway windows show navigation data:

A The boat position B The destination point marked with a circle. C The boat’s plotted course to the destination. D Two CDI lines, parallel to the boat’s plotted course,

which indicate the maximum expected deviation

from the plotted course. For more information, see Appendix C. If the unit is connected to an autopilot, the unit will send

data to the autopilot to steer the boat to the destination. Start the autopilot before starting to navigate to the point.

If the unit has no autopilot, steer the boat manually.

use the boat position and destination on the chart or •

highway windows;

use navigation data shown on the data header or;•

use COG and BRG on the compass.•

Note:

If the XTE alarm is enabled, an alarm will sound if the •

boat deviates too much from its intended course.

If the arrival radius alarm is enabled, then an alarm •

will sound to show that the boat has reached the

destination.

When the destination is reached an arrival warning •

appears with the option to cancel navigation.

3-1-2 Going to a waypoint or to a point on the chart

A waypoint is a position that you can set on the chart, for

example a shing spot or a point on a route.

3-5 Tracks and tracking

Tracking records the boat’s position to memory at regular intervals, which can be time or distance intervals.

The track of where the boat has been can be shown on the chart. The unit can show one track while recording another.

The unit can store 10 tracks. Each can hold 2000 waypoints.

Tip: Record a reference track and then use the track to help navigate the same trip later. For example, record a reference track as you leave harbour. Then if you return to harbour and visibility is poor, select the chart and navigate manually along the reference track back into the harbour. Record reference tracks in good conditions.

When recording is on and the track becomes full then recording continues and the oldest points in the track are deleted. The maximum length of a track depends on the selected track interval: a small interval will give a shorter, more detailed track and a long interval will give a longer, less detailed track, as shown in these examples:

Satellites9

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.

GPS receiver (Optional)

Simrad GPS units have a sensitive 12-channel receiver, which tracks signals from all GPS satellites visible above the horizon and uses measurements from all satellites more than 5° above the horizon to calculate the position.

Each time a GPS receiver is turned on, it normally takes

about 50 seconds before it outputs the rst position.

Under some circumstances it will take up to two minutes or longer.

CAUTION

WARNING

Echosounder shnding: Introduction10

Use the automatic Cruising or Fishing modes when learning to use the unit or 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.

When the pulse meets an object, such as a sh or the bottom, it is partly reected back up towards the boat

as an echo. The depth of the object or bottom is calculated by the unit by measuring the time taken between sending a pulse and receiving the echo. When an echo has been returned, the next pulse is sent.

The unit converts each echo into an electronic signal, shown as a vertical line of pixels. The most recent echo appears on the extreme right of the window, with the older echoes being scrolled towards the left, eventually disappearing off the window.

The scroll speed depends upon the water depth and scroll speed setting.

The appearance of echoes shown are affected by:

The unit settings.•

Echoes (different sh types, different bottom types, •

wrecks and seaweed. Noise (water clarity and bubbles.)•

Cruise, Fishing and Manual Modes

The unit has three echosounder operating modes:

• Cruising mode: Use this when on the move. The unit automatically adjusts its settings to compensate for water clarity and to display the bottom.

• Fishing mode: Use this when shing. The unit automatically adjusts its settings to compensate for

water clarity and to best display sh, the bottom and

other details.

• Manual mode: Use this to ne-tune the unit settings by hand. Best results are often achieved in manual mode, but practice and experience are required to obtain the optimum settings for different conditions.

Simrad NX40/45 Installation and Operation Manual 37

9-2 Interpreting the display

The echosounder windows do not show a xed 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. In deep water, the history moves across the window more slowly because the echoes take longer to travel between the bottom and the boat. For example, when the scroll speed

is set to about 2 minutes for the data to move across the window, whereas at 20 ft (6 m) it takes only about 25 seconds.

The scroll speed can be set by the user to display either

a longer history with less sh information or a shorter history with more sh details.

If the boat is anchored, the echoes all come from the

same area of bottom. This produces a at bottom trace

on the window. The screen shot shows a typical echosounder window

with the Fish symbols turned Off. The echosounder pulse generated by the unit transducer travels down through the water, spreading outwards in a cone shape. The cone width is dependent upon the frequency of the pulse; at 50 kHz it is approximately 45°, and at 200 kHz it is approximately 11°.

Fast, at depths over 1000 ft (300 m) it takes

A School of sh

B Single sh

C Hard bottoms such as rock and coral show as wide

bands

D Soft bottoms such as mud, weed and sand show as

narrow bands

The differences in the cone width affect what is shown.

Strength of echoes

The colors indicate differences in the strength of the echo. The strength varies with several factors, such as the:

Size of the sh, school of sh or other object.•

Depth of the sh or object.•

Location of the sh or object. (The area covered by •

the ultrasonic pulse is a rough cone shape and the echoes are strongest in the middle.)

Simrad NX40/45 Installation and Operation Manual38

CAUTION

DANGER

WARNING

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.

Frequency and cone width

Clarity of water. Particles or air in the water reduce • the strength of the echo.

Composition or density of the object or bottom.•

Bottom types

Mud, weed and sandy bottoms tend to weaken and scatter the echosounder pulse, resulting in a weak echo.

Hard, rocky or coral bottoms reect the pulse, resulting

in a strong 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 sh 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.

When looking for sh with the wide angled 50 kHz

frequency, be aware of increased shadows. Use the high frequency 200 kHz in areas that have rocks and ledges because this frequency reduces the shadow effect considerably.

9-3 Single and Dual frequency shnding

Sounder frequencies

The unit has two echosounder frequencies, 200 kHz and 50 kHz..

To select the echosounder frequency

> Frequency > 200 kHz or 50 kHz or Mixed

When to use 200 kHz

The 200 kHz frequency is especially suitable for use in shallow and medium depth water, typically less than 500 ft (150 m) and while running at speed.

At 200 kHz, the narrow cone reduces any noise caused by air bubbles.

The 200 kHz frequency generates a higher denition pulse

which produces little shadow and returns excellent detail over a small area of bottom. Therefore, it gives excellent bottom discrimination capability and is particularly good

at showing individual sh, including bottom dwellers.

When to use 50 kHz

The 50 kHz frequency is particularly suitable for use in deep water, typically greater than 500 ft (150 m).

At 50 kHz, the cone covers an area of water about four times wider than the 200 kHz cone and penetrates to a greater depth with minimal loss of the return signal.

However, it produces a lower denition display with more

shadow compared to the 200 kHz frequency. This means

that a group of small sh, for example, could be shown as a single item, while any sh very close to the bottom

Example of shadows

may not be found at all. This frequency is useful for getting a deep, wide

overview of the area so that any areas of interest can

be identied 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, lling in

detailed echoes in the center of the echosounder cone.

When to use 50/200 kHz

Operating the unit at both 50 kHz and 200 kHz simultaneously on a split window can be very useful when operating in shallow to medium water, typically

less than 500 ft (150 m), because the 50 kHz section of the window shows the general area, while the 200 kHz section can be viewed simultaneously for a more detailed look at any interesting feature.

To use 50/200 kHz, select the Split 50/200 window.

Where to nd sh

Underwater features like reefs, wrecks and rocky

outcrops attract sh. Use the 50 kHz or 50/200 kHz frequency window to nd these features, then look for sh by passing over the feature slowly several times using the Zoom window. If there is a current, the sh

will often be found downstream of the feature. A weak fuzzy band may appear between the bottom

trace and surface. This might indicate a thermocline - a rapid change in water temperature, such as the edge of a warm or cold current. The temperature difference can

form a barrier which the sh may not swim through. In fresh water, sh often collect around a thermocline.

Fish arches

In good conditions, a sh passing through the coneshaped ultrasonic pulse is shown as a sh arch. The

50 kHz frequency uses a wider cone than the 200 kHz

frequency. This makes the sh arches easier to see.

A sh arch starts when a sh enters the weak edge of

the echosounder cone, generating a weak echo that is

shown as the start of the sh arch. As the sh moves

closer to the middle of the cone, the distance between

the transducer and the sh reduces and the echo is

shown at progressively shallower depths, producing a

rising shape. When the sh passes directly beneath the

middle of the cone, the echo becomes strongest and

thickest. As the sh passes out of the middle of the cone

the reverse happens with a progressively weaker and deeper echo.

There are many reasons why sh arches may not be

seen. For example:

Poor transducer installation (see Transom Transducers • Installation Guide).

If the boat is anchored then sh will tend to show •

on the window as horizontal lines as they swim into and out of the transducer echosounder beam.

Slow speeds in deeper water give the best sh arch

returns.

Range is important. It will be much easier to see sh •

arches when using zoom mode to concentrate on a particular section of water, rather than just showing everything from the surface to the bottom. Zooming increases screen resolution and is necessary for

good sh arches.

It is difcult to get sh arches in shallow water as the •

transducer echosounder beam is very narrow near

the surface and sh do not stay within the beam long enough to show an arch. Several sh in shallow

Wave motion may result in distorted sh 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. Auto range is recommended for normal operation.

To set Auto mode

Go to a echosounder window >

> Range >

Auto

• Manual: The unit does not adjust the range automatically. If the bottom depth is below the range, the bottom will not appear on the window. Manual range is useful if the bottom depth changes rapidly, because Auto range will cause the window to change range frequently.

Go to a echosounder window >

Zoom range and offset

The echosounder Zoom and Bottom windows can show a

magnied part of the range.

9-6 Gain and threshold

Gain and threshold settings control the amount of detail shown on a echosounder window:

Gain: The gain of the echosounder receiver. The gain should be high to display good detail, but if the gain is too high then information from the strong bottom signal is lost and false echoes might be shown. There is a separate gain setting for each echosounder frequency, 50 kHz and 200 kHz.

Threshold: Return echoes less than the threshold are ignored. The threshold should be as low as possible, but if the threshold is too low, unwanted noise will be shown. Threshold is set as a percentage of gain. For example, if the threshold is 50 %, then return echoes less than 50 % of the maximum signal are ignored. There is a separate threshold setting for each echosounder frequency, 50 kHz and 200 kHz.

Use the Auto range when learning to use the unit or when travelling at speed.

Fish recognition

The echo strengths shown on the A-scope can be useful

in recognizing the type of sh. Different species of sh

have different sizes and shapes of swim bladders. The

air in the swim bladder reects the ultrasonic pulse, so the strength of the echo varies between sh species

according to the size and shape of the swim bladder.

When catching sh from a school, note the species and

the strength of the echo that it returns on the A-scope. Then, when that particular echo is seen again, it is likely

to be the same sh species.

Bottom type

The shape of the echo strengths in the A-Scope can help you to recognise the type of bottom.

Fuel functions and display14

CAUTION

WARNING

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 ow sensor installed to measure the engine’s fuel ow.

The NX40/45 use these ows, 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.• set low fuel alarms.• make fuel consumption curves - graphs of fuel •

consumption and boat speed as a function of engine RPM - to monitor and optimize boat performance.

13-2 Fuel display

To go to the Fuel display

> More > Fuel

The display differs according to the number of engines and tanks.

To switch between a Summary or a Fuel curve display

To ensure the fuel data is accurate:

When you add or • remove fuel from a tank, tell the NX40/45.

If the boat has petrol/ • gasoline sensors, calibrate them during installation or if the fuel readings seem inaccurate.

Choose an appropriate • type of boat speed sensor to calculate economy, range and the fuel consumption curve.

If the boat uses a • paddlewheel sensor to measure speed, calibrate it during installation or if the speed readings seem inaccurate.

If engine RPM is available and if you have made and selected a Fuel Consumption Curve.

The Fuel display shows:

Speed RPM (if available)

If engine RPM is not available, the display shows depth.

Remaining

The fuel remaining in the tank(s) is shown as a vertical gauge on the right of the display. The height of the yellow bar(s) show how much fuel remains in the tank(s). If you have set a low fuel alarm, a red bar shows the level at which the alarm will trigger. If there are two tanks, the left bar shows the port tank, the right bar shows the starboard tank.

The fuel used by each engine and the total fuel used are shown.

Fuel ow

The fuel ow for the engine(s). On a multi engine boat,

the data for the port engine is on the left of the display.

Use the ows to check the load of each engine.

Range

The estimated boat range at the current fuel ow. The

value can depend on the type of speed sensor.

Economy

The distance travelled per unit of fuel used. The value can depend on the type of speed sensor. The larger the value, the better the fuel economy. Adjust the throttle and trim to achieve the best economy.

Fuel consumption curve

A graph of fuel consumption and boat speed as a function of engine RPM. Use the curve to monitor and optimize boat performance.

13-3 When you add or remove fuel

When you add or remove fuel, you must tell the NX40/45, otherwise the fuel data will be meaningless.

Note: Underoor fuel tanks are often difcult to rell 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.

Write down how much fuel you add. Change the number.

> Add fuel

On a multi-tank boat select the tank you have added fuel to.

Note: If you follow procedure B every time you add fuel, then a small error will accumulate, because it is hard to measure exactly how much fuel you add. To avoid this,

completely ll the tank and follow procedure A about

every tenth time you add fuel.

C - Removing fuel

Before removing fuel

> Set remaining

On a multi-tank boat, select the tank that you are • removing fuel from.

Write down the value of Remaining for the tank; this • is the amount of fuel originally in the tank.

Remove fuel from the tank and write down how • much fuel you remove.

Subtract the amount of fuel you removed from the • amount of fuel originally in the tank to calculate the amount of fuel now in the tank.

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 Boat speed sensors 13-5-1 Selecting a boat speed sensor

The fuel calculations can use boat speeds from the GPS, or from a paddlewheel sensor or pitot sensor if these optional sensors are installed:

Paddlewheel and pitot sensors measure the speed • through the water; GPS speed is speed over ground; these sensors can give different values for Range, Economy and the fuel consumption curves.

A pitot sensor is more accurate than a paddlewheel • sensor at high speeds but is not accurate at low speeds. A paddlewheel sensor is more accurate than a pitot sensor at low speeds.

To select an optional speed sensor

> > Fuel > Speed source

To use a paddlewheel or pitot sensor > Water speed. To use GPS speed > Ground speed

If you have both a paddlewheel sensor and a pitot sensor

> Smart Craft > Speed type > Paddlewheel or

Pitot

Tip: You can select a different speed sensor during

a trip.

Simrad NX40/45 Installation and Operation Manual 55

13-5-2 Water speed and ground speed

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.

Water speed is better for measuring the boat’s potential performance, Ground speed is better for going to a destination because it takes currents into account.

When the current is from ahead, ground speed is less than water speed.

For Example 1

If the boat travels for one hour, uses 3 gallons of fuel per hour and has 50 gallons of fuel left:

When the current is from behind, ground speed is more than water speed.

13-6 Fuel consumption curves

A fuel consumption curve shows fuel consumption (fuel used per unit of distance travelled) and boat speed as a function of engine RPM. Fuel consumption curves require engine RPM, which requires SmartCraft to be installed. Fuel consumption curves are powerful tools for assessing boat performance in different conditions and for helping you to run at the most economical speed for the conditions.

13-6-1 Making a fuel consumption curve

To make a fuel consumption curve you will need to run the boat in a straight line for about 15 minutes using the

engine’s full RPM range. For your rst curve, choose a

calm day with light wind and little current; have a typical load and a freshly cleaned hull. Later, you can make fuel

Example 1:

A (water speed) = 10 knts. B (current) = 4 knts.

Gives a ground speed of 6 knots.

Example 2:

A (water speed) = 10 knts. B (current) = 4 knts at 45º.

Gives a ground speed of about 8 knts.

Example 3:

A (water speed) = 10 knts. B (current) = 4 knts.

Gives a ground speed of 14 knots.

Example 4:

A (water speed) = 10 knts. B (current) = 4 knts at 45º.

Gives a ground speed of about 13 knts.

Simrad NX40/45 Installation and Operation Manual56

consumption curves for different boat, weather or sea

conditions. Compare these with your rst 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 • Select •

Enter the comfortable maximum RPM you know you • can achieve for the engine rather than the maker’s value.

The NX40/45 then asks you to set the minimum • RPM. Set the throttle to idle; on a multi engine boat set all engines to about the same idle RPM. Now, do not change the engine speed. Wait for about

60 seconds for the boat to stabilise, then press Wait while the fuel computer records the data.

The NX40/45 then asks you to set the throttle to • achieve a target RPM. On a multi engine boat set all engines to about the target RPM. When the engine RPMs are correct, the Target RPM box will turn green. Now, do not change the engine speed. Wait for about 60 seconds for the boat to stabilise, ensuring

the Target RPM box stays green. Then press while the fuel computer records the data.

The NX40/45 repeats the above step to record data • up to the maximum RPM. Then the NX40/45 asks if you want to save the curve. Select Yes. The fuel computer asks for a name for the curve. Change

the default name if required. Then press NX40/45 stores the new curve.

RPM is the average of the two RPMs.

B Red curve: boat speeds at different RPMs recorded

when you made this fuel consumption curve.

C Red marker: the boat speed now. This marker is

below the red curve, showing that the boat speed now at this RPM is less than when you recorded the curve.

D Blue curve: fuel consumption at different RPMs

recorded when you made this fuel consumption curve.

E Blue marker: the fuel consumption now. This marker

is below the blue curve, showing that the fuel consumption now at this RPM is better than when you recorded the curve.

F If the blue curve has a dip, then running the boat at

this RPM will give the best speed for the least fuel consumption.

13-7 Calibration

Calibrate petrol/gasoline fuel ow 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.

Calibrating a sensor requires accurate • measurement of the fuel consumption. This is best done using a small portable tank. At least 4 gallons (15 litres) of fuel should be used to ensure an accurate calibration.

•

It is often very difcult to ll underoor tanks to the

same level twice due to air pockets, so the more fuel used, the more accurate the calibration.

To calibrate the sensor(s)

Record the level of the fuel in the tank(s).• Connect the portable tank(s) to the engine through •

the fuel sensor(s). Run the engine at normal cruising speed until at •

least 4 gallons (15 litres) of fuel has been used per engine.

Check the actual amount of fuel used per engine by •

relling the portable tank(s) to the original level and

noting the reading(s) of the fuel dispenser’s gauge.

> > Fuel > Setup engines

• On a single engine boat, select • Calibrate and change

the shown value to be equal to the reading of the fuel dispenser’s gauge, then press

On a multi-engine boat select the engine. Select •

Calibrate and change the shown value to be equal

to the reading of the fuel dispenser’s gauge, then press

. Repeat for the other engines.

AIS17

AIS is short for Automatic Identication 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.

This unit can receive and display AIS information when connected to an AIS receiver. Available AIS vessels transmitting in the local area are shown on the chart when this feature is enabled.

We recommend the Simrad AI50 for the NX40/45. The following AIS receivers are also supported by this unit:

Comar SLR200 (external GPS)• Weatherdock Two Channel AIS Receiver• NASA Marine AIS Engine 2 channel Receiver (external •

GPS).

To enable AIS from the system menu check the box.

Radar 18

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 reected

back from any solid objects such as land masses or other boats. These objects are called targets and are shown on the radar window.

The scanner rotates through 360° so the radar window shows all of the area around your boat within the range of the scanner, producing a map-like display called the PPI (Plan Position Indicator).

Typically, your boat is in the center of the radar window with concentric range rings surrounding it. The range rings help you to quickly estimate the distance to various targets.

17-1 Radar window

The radar window shows:

A B C D

A Distance between each range ring (in

this example, 1/8 nautical mile)

17-2 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. An open array will be rotating.

If you want to save on power but be able to start transmitting immediately, use standby mode.

17-3 Enabling the radar functionality

When the radar is enabled, it will turn on, warm up, and enter standby mode.

To enable the radar functionality

> System

Set Radar to • . The radar immediately turns on and enters warm-up •

mode. A message shows how long this will take. When the warm-up period is complete, the radar •

17-6 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 spots) caused by obstructions such as funnels or masts will be minimized. If you’re having problems with these, you may need to relocate the radar. Consult the Installation Guide for your Simrad radar or talk to your dealer or installer.

Multiple echoes off the same object are most likely to occur when you are close to a large target and are usually only a temporary nuisance.

You can adjust the radar to reduce the effects of sea clutter, rain clutter, and interference from other radars. You can also change the gain mode setting and the gain level setting to help reduce false echoes.

To adjust the radar

> Presentation > Adjust Radar >

17-6-1 Changing the gain mode

Use the radar gain mode to specify whether you want to adjust the radar gain yourself or have it adjusted automatically.

To change the radar gain mode

> Adjust Radar > Gain Mode

Simrad NX40/45 Installation and Operation Manual68

• Manual. Adjust the radar gain yourself to suit your local conditions and preferences.

• Auto. The radar gain is adjusted automatically.

17-6-2 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 difcult 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.)

To change the radar gain level

> Adjust Radar > Gain Level >

17-6-3 Changing the sea clutter mode (Manual mode)

Sea clutter usually appears as confusing, random signals close to your boat on the radar window.

High waves that can reect the radar signal will produce

the maximum amount of sea clutter. You can change the sea clutter mode yourself or have

it changed automatically to compensate for the sea conditions.

To change the sea clutter mode

> Adjust Radar > Sea Clutter

• Manual. Adjust the sea clutter setting yourself.

• Harbour. The sea clutter setting is adjusted automatically to suit a harbour environment.

• Offshore. The sea clutter setting is adjusted automatically to suit an offshore environment.

Range Rider• . Adjust the sea clutter setting yourself for a particular radar range, then have those settings stored and automatically re-used whenever you operate at that range again.

17-6-4 Changing the sea clutter level

If the sea clutter level is set too low, a lot of sea clutter will be shown. If the sea clutter level is set too high,

Simrad NX40/45 Installation and Operation Manual 69

small targets may not be shown in the radar window. If the sea clutter mode is set to Harbour or Offshore, and

you adjust the sea clutter level manually, the sea clutter mode changes 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 >

17-6-5 Changing the rain clutter

Rain clutter consists of random dots that can merge into

badly-dened echoes on your radar screen.

The random signals are returned from rain, hail, sleet, or snow and can result in a confusing display.

If the rain clutter is set too low, there will be excessive rain clutter shown whenever it’s raining. If the rain clutter is set too high, very large targets such as the coastline will appear to be hollow.

To change the rain clutter setting

> Adjust Radar > Rain clutter >

17-6-6 Changing the threshold level

Use this to dene the threshold level of the weakest echo

that you want to show on the radar screen. The threshold level is shown as a percentage.

100% is the maximum threshold level, meaning that only the strongest echoes are shown. 0% is the minimum threshold level, meaning that all echoes are shown.

To change the threshold level

> Presentation > Threshold >

17-7 Changing the echo expansion setting

If you have several small targets in view and want to make them easier to see, use the echo expansion option.

Note that the resolution decreases as the target size increases, so use this option only when target detection and visibility is more important that the quality of the display.

Simrad NX40/45 Installation and Operation Manual70

To change the echo expansion setting

> Presentation > Echo Expansion

• Off. No echo expansion.

• 1. Targets expanded x 2.

• 2. Targets expanded x 3.

17-8 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. If the radar motion mode is relative, any target that is moving relative to your boat will leave a trail.

To change the target trails setting

> Presentation

Set the • Target trails option to (target trails are on) or (target trails are off).

17-9 Using the VRM/EBL

Use one, or both of the VRM/EBL (Variable Range

Markers/Electronic Bearing Lines) to quickly nd the

precise range and bearing of a target.

A VRM can be xed or oating. Use the VRM to nd the

range (distance) to the target.

A xed VRM is shown as a thin, dashed, circle centerd • around your boat. Use this to nd the distance of a

target from your boat. You can move the center of the VRM away from your •

boat; for example, to measure the distance between

two islands. This is called a oating VRM.

The EBL is shown as a thin, dashed line extending from the center of the VRM to the edge of the radar window.

Use the EBL to nd the bearing of the target.

Zero bearing Use the zero bearing alignment to

rotate the radar image, one degree at a time, so that a known object dead ahead is directly under the boat’s heading marker.

This means that the radar image is

aligned with the shown chart and the compass. An accurate bearing alignment is particularly important when the radar image is overlaid onto the chart.

Adjust this on a chart window with

the radar overlay on.

Select Zero bearing then use the

cursor to enter the new bearing angle.

Zero range The zero range is also known as the

radar range offset and as the trigger delay.

If your radar window shows a blank,

black circle around the center or a solid circle of color at the center, you need to adjust the zero range setting until this circle disappears or almost disappears. Ideally, the radar sweep should start at your boat (a radar range of zero).

Fuel consumption can change drastically depending upon the boat loading and the sea conditions. Always carry adequate fuel for the journey, plus a reserve.

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.

Keel Offset A depth transducer measures

depths below where the transducer is mounted on the boat, usually the bottom of the boat. The unit calculates the depths to display by adding the keel offset to all measured depths.

A Have a zero keel offset to display

depths below the transducer.

B Enter a positive keel offset to

increase the shown depth. For example to display the total depths below the surface, enter the depth of the transducer below the surface.

C Enter a negative keel offset to

decrease the shown depth. For example, to display the depths of clear water below the boat, enter minus the depth of the deepest part

19-3 Installation: The display unit

Start by selecting a suitable mounting position for the NX40/45 display unit:

Consider the best possible position for viewing and • operating the NX40/45. This will generally be a

relatively shaded area free from obstructions. At least 100 mm (4”) away from the compass, at •

least 300 mm (12”) away from any radio transmitter and at least 1.2 m (4 ft) away from any antenna.

For optimum performance and reliability consider • mounting the unit where it will not be unnecessarily exposed to direct sunlight, water and protected from other physical damage which could occur during rough sea passages.

If bracket mounting chose a at area where the •

display will not be subjected excessive vibration. Select an area with adequate clearance for cabling •

and access to the power source. Before drilling any holes ensure that the drill area is •

free from cables or other obstructions.

There are two mounting arrangements:

Flush Mounting the NX40/45

Attach the ush mounting template to the selected •

mounting position using adhesive tape. Drill a pilot hole for each of the hole saw cuts shown •

on the template before cutting the larger hole with the hole saw.

Next cut all the way around the inside of the cut-out • line with a saw to remove the waste material shown on the template.

Check that the unit ts correctly in the cut out area. • Adjust the t with a le if required.

Select a 2-3.5 mm 1/8” drill bit depending on • hardness of material to drill. Smaller diameter holes will be needed for soft woods and larger diameter pilot holes will be required if mounting to hard

materials such as berglass (we recommend 3.5 mm (1/8”) for berglass and Aluminum).

With the selected drill bit drill the 4 pilot holes for the • 8 gauge screws used to attach the unit. These are indicated on the corners of the mounting template.

Connect all cables to the rear of the unit before • placing the unit into the console.

Firmly secure the unit in place with the 4 x 8 gauge • self tapping screws.

Simrad NX40/45 Installation and Operation Manual98

Note: the 5 x 14G self tapping screws are for bracket mounting only.

To nish off the installation rmly clip the front bezel •

in place.

Bracket Mounting the NX40/45

An alternative to ush mounting the NX40/45 is to

bracket mount the unit. This method has the advantage that the display can be easily removed when it is not in use. The display may be tilted for best possible viewing angle when bracket mounted.

Note: The mounting bracket does not allow for rotation of the unit to the left and right.

Use the mounting bracket as a template to mark the • 5 positions of the screw holes.

Select a suitable drill bit (note: larger diameter pilot •

holes may be required if mounting to berglass) and

drill 5 pilot holes in the marked positions. Secure the mounting bracket using the 5 x 14G self •

tapping screws. Slide the NX40/45 into the mounting bracket and •

secure in place with the bracket knobs.
