Installation

Location
The FISH400 and FISH440 are water resistant and may be mounted and operated in many positions thanks to its compact and robust bracket, associated with a swivel support. When installing the display head, select a position where it will be: at least 300 mm ( 12" ) away from the compass. at least 300 mm ( 12" ) away from any radio transmitter, such as the VHF. easy to read by the helmsman and crew while under way. protected from physical damage during rough sea passages. have easy access to the 12 volt power source. convenient to route the transducer cables.
Note It may be advisable to install the transducer and wiring before finalising the location of the display head and bracket.

Installation The Transducer
Read this section carefully before attempting the transducer installation. Remember, the transducer location is the most critical part of the installation. If this is not done properly, the transducer cant perform at its designed potential. Therefore the performance of the fishfinder, especially at higher speeds, will not be satisfactory.

Mounting

Once the best location of the transducer is determined, hold the transducer and bracket against the transom. The bottom surface of the transducer needs to sit parallel to the surface of the water for the best signal return. The lower face of the transducer should extend down below the bottom of the hull so that it will be below the surface of the water at high speeds. (See fig. 2.1)

Transom Mount Transducer

The transducer can be installed on any outboard or sterndrive powered boat. The transom mount transducer has a safety kick up mounting bracket to help minimise damage to the transducer should it impact the bottom or floating debris in the water. Select a position for the transducer that will: allow the transducer a smooth flow of water over its surface at all times. ensure a mount as deep in the water as possible. be clear of any interference from the trailer when launching or retrieving the boat. be away from planing strakes or other projections from the hull that may cause aerated water to flow over the face of the transducer. be away from the propeller be at least 150 mm ( 6" ) away from the keel of the boat.

fig. 2.1

Minimum immersion required
Mark the transom through the bracket slots to correctly place the two outer screws. Now drill the two holes in the centre of the slots. This will allow you to adjust the transducer position later on if required. Use two of the three stainless screws supplied to attach the bracket to the transom. Ensure the lower face of the transducer is parallel with the ground (see fig. 3.1 and 3.2). Tighten the two screws.

Electrical protection

Finally, drill a hole and insert the third screw in the middle of the bracket. It is advisable to fill holes with a sealing compound before inserting screws (see fig. 3.3).

fig. 3.3

Your fishfinder has an internal electrical protection system for over voltage and short circuit situations. It is not necessary to use a fuse or a circuit breaker.

If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps, and other equipment can affect the display. Both the power and depth transducer cables lead into one four pin connector on the FISH400 or the eight pin connector on the FISH440. This plugs into a single socket in the rear of the instrument. Connect the red wire of the two-core power cable to the positive supply and the black wire to the electrical ground. The shortest and most direct connection to the boats battery will help to eliminate any problems due to voltage drop or electrical interference.
Other Types of Transducers
It is possible to use your NAVMAN Fish Finder with all the NAVMAN Transducers Range (including thru-hull mounting). For this purpose you need to purchase the Y adaptors for the FISH400 and FISH440, which will allow you to separate the power cable from the transducers cable.

Operation
The FISH400 and FISH440 use sonar technology to display lake or seabed contours and to detect fish. 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 LCD screen is menu driven for ease of use. 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

Display and Operating Modes
The FISH400 has five modes of operation. These are Echo, Echo + Analogue Scope, AutoFish, AutoFish + Analogue Scope and Navigate.

Autofish mode

Echo mode
The Autofish mode automatically analyses the return echoes and displays echoes with fish icons (the bigger the echoes, the bigger the icon!). The Echo mode displays the return signals as they are received from the transducer. Fish appear as arches and not as fish symbols. The length of the arch will indicate the relative size of the return echo and size of the fish. The Echo mode enables the unit to display echoes caused by surface turbulence, thermal layers, plankton or transducer noise when the boat is moving. This mode is very useful for the experienced user. The digital display in this sample window is indicating the depth of the bottom. The display units are also user selectable The return echo is caused when the sonar beam strikes the air stored in the fishes swim bladder. Certain types of fish have larger swim bladders than normal so the size of the icon is not always a reliable way to indicate the relative size of the fish. In the Autofish mode, unnecessary surface noise is reduced from the top of the screen. This mode is recommended when your boat is moving along at higher speeds.

Analogue Scope

Displays depth only

Current Echo

The Analogue-scope function is available in either the Echo or Autofish modes. 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.

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. If All is selected then the unit will automatically adjust the display range to show both the top of the water and the sea bed no matter what the depth of the water is.

Setting the gain

Gain function
The gain is a measure of ability to receive weak signals. The higher the gain setting, the better the unit is able to pick up weak return signals. Deep water operation requires the gain to be set to a higher value due to loss of signal in the water. There are two gain modes that can be selected, Manual and Auto. If Manual is selected then a gain setting from 0 to 15 must also be entered. This will be the value of gain that is always used when displaying information on the screen. A low gain number may be suitable in shallow water but will need to be increased for deep water operation If Auto is selected then the gain will automatically vary as the water depth changes. This feature is particularly useful if you are fishing areas where the depth changes suddenly. In Auto mode, you can set the auto-gain value to provide a consistent image of the bottom, regardless of the bottom type. A low auto-gain setting will cause a thin bottom image to be displayed. A high autogain setting will result in a thick bottom image. This adjustment is particularly useful with a weak return signal from a muddy or silty bottom. Normally, in these conditions the auto-gain will increase the gain to a level that may make the display appear too cluttered, making it difficult to distinguish fish. In this situation the auto-gain can be reduced to display a weak bottom image but with improved fish images. Press the displayed

key until the gain menu is
Press either the key or the key to move the pointer to the desired mode of operation If the desired mode is Manual then use the V or the ^ key to adjust the value to the desired level Press the key to accept the choice and return to normal display mode If the desired mode is Auto then use the V or the ^ key to adjust the value to the desired level. In Auto mode the gain will be controlled to show the same bottom detail irregardless of depth

Display scroll speed

The scroll speed is the speed that the picture moves across the screen. It is adjustable in three distinct steps, slow, medium and fast. In general the faster scroll speed will work better with higher boat speeds. The slower scroll speeds are more suitable for slow speed trolling and slower vessels. The most suitable scroll speed is determined by experimentation

Setting the scroll speed

Press the displayed
key until the speed menu is
Press either the key or the key to move the pointer to the desired scroll speed Press the key to accept the choice and return to normal display mode

Alarms

There are three different types of alarms, Fish, Shallow, and Deep. All the alarms activate the internal buzzer if their alarm condition is met. The buzzer will provide three different alarm signals. A short alarm signal for a mid water echo, such as a fish, a long continuous signal for a shallow water alarm and a series of short signals for a deep alarm. Each alarm can be individually enabled or disabled. All enabled alarms can be simultaneously disabled with a single key press. The alarm indicator bar on the top left of the display shows which alarms have been selected. They are fish F, shallow S, and deep D. Fish Alarm Alerts you with a single short signal when an object that could be a fish is detected. The alarm for a small fish is shorter than the alarm for a bigger fish. Shallow Alarm Alerts you when the water depth is shallower than the shallow alarm setting, i.e., the water becomes too shallow. Deep Alarm Alerts you when the water depth is deeper the deep alarm setting, i.e., the water becomes to deep. Press the displayed

Alarms on the FISH440

When either or all of the Fish, Shallow or Deep alarms are active they are displayed on the screen. When an alarm is triggered there is a beep and the corresponding alarms figure flashes on and off.
Press either the key or the key to move the pointer to the required alarm Use the V or the ^ key to adjust the alarm setting to the desired depth level. OFF is shown if shallow alarm value is 0 or deep alarm value of 600 feet is selected Press the key to accept the choice and return to normal display mode

Anchor Drag Alarm

The Shallow and Deep Alarms can be set just above and below your anchored depth. An alarm will sound if your anchor drags and you drift into deeper or shallower water. Be sure to disable the fish alarms in this mode to prevent false anchor drag alarms due to fish.

Setup Menu

The setup menu enables you to customise the look and feel of the instrument. There are six parameters that can be adjusted. Lamp intensity, units of measure, keel offset, training mode, LCD contrast and white line operation. Lamp Intensity The intensity of the night vision lights can be adjusted from 1 to 7 and OFF. Units Of Measure Depth can be displayed in either feet (FT), meters (M), or fathoms (FA). Keel Offset The depth of water is normally measured from the face of the transducer to the bottom. You can enter an offset which will be added or subtracted from the calculated depth before it is displayed on the LCD. Entering a negative offset can be used to display the depth of water below the keel. Entering a positive offset can be used to show depth from the surface to the bottom. When entering zero as an offset, the fishfinder will display depth of water below the transducer. Training Mode This setting will enable a simulation mode which allows you to learn to use all the different features in this instrument. LCD Contrast You can adjust contrast level from 0 to 7 to match your preference. Special circuitry will also automatically adjust the contrast for changes due to temperature. White Line This feature displays the bottom signal as a thin line, with a variable width band beneath it. This indicates the bottom hardness and also allows you to separate targets near the bottom of the sea bed. This function will also remove most surface echo signals from the top of the screen.

Changing the speed & temperature setup

The model FISH440 fishfinder is able to display boat speed, water temperature, and water depth. 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. The calibration value is saved in memory automatically. Speed units of measure Speed can be displayed in either knots (KTS) miles per hour (MPH) or kilometres per hour (KPH). Speed calibration If the displayed speed is known to be wrong then it can be adjusted using this function. The calibration value is saved in memory automatically.

Troubleshooting

The Fishfinder wont turn on:
1. Check the power cable socket at the back of the Fishfinder. 2. Make certain the power cables red wire connects to the positive battery terminal and the black wire to negative or ground. 3. Measure the voltage at the units power terminals. It should be at least 10 volts. If it isnt: 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.
The Fishfinder freezes, locks up, or operates erratically:
1. Electrical noise from the boats engine or an accessory may be interfering with the sonar unit. To stop this, try: re-routing the power and transducer cables away from the other electrical wiring on the boat routing the units power cable directly to the battery instead of through a fuse block or ignition switch 2. Inspect the transducer cable for damage or pinched wires. 3. Check the transducer and power connector. Make certain it is securely plugged into the unit.
Weak bottom echo, digital readings erratic, or no fish signals:
1. Make certain the transducer is pointing straight down. 2. Electrical noise from the boats motor can interfere with the Fishfinder. This causes the Fishfinder to automatically decrease the gain level unless the gain control has been set manually. The Fishfinder thus eliminates weaker signals such as fish or even the sea bed from the display. 3. Manual gain may be set too low, if you have the instrument set in manual mode. 4. The water may be deeper than the Fishfinders ability to find the bottom. If it cannot find the bottom return signal while it is in the automatic mode, the display will flash continuously. It may change the range to a realistic one, and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 5. Check the battery voltage. If it is too low, the units transmitter power is also low, reducing its ability to find the bottom or targets.

Bottom echo disappears or erratic digital reading while your boat is moving:
1. The transducer may be in turbulent water. Air bubbles in the water disrupt the Fishfinder signals, interfering with its ability to find the bottom or other targets. This often happens when you reverse the boat. The transducer must be mounted in a smooth flow of water in order for the Fishfinder to work at all boat speeds. 2. Again, electrical noise from the boats motor can interfere with the Fishfinder.

1 Introduction

Congratulations on choosing a NAVMAN fishfinder. For maximum benefit, please read this manual carefully before installation and use. This manual describes the installation and operation procedures for the FISH 4100 and FISH 4150. The manual generally refers to both products as the NAVMAN fishfinder. The product name is used only when describing features specific to that particular fishfinder. At the same time, SBN Technology uses active noise control to reject interference, which can often be mistaken by fishfinders for true returns. Using SBN Technology, the NAVMAN fishfinder analyses the reflections from each pulse, filters false returns and displays what is in the water under the boat. The distinctions between the four levels of shading help the user to better interpret what is in the water and what type of bottom is under the boat.

The NAVMAN Fishfinder

The FISH 4100 is an ultrasonic fishfinder. It provides powerful software and a large, high-resolution screen with a zoom facility and a choice of fish symbols. As well as detecting fish, the FISH 4100 measures the water depth, battery voltage and engine hours. The FISH 4150 also measures the water temperature, the boat speed and has two distance logs (Trip Log and Total Log). An installed NAVMAN fishfinder has two parts: - The transducer attached to the hull. - The display unit. The transducer generates an ultrasonic pulse (sound that is above the hearing range of the human ear), which travels down towards the bottom, spreading out into a cone shape. When the pulse meets an object, such as a fish or the bottom, some of the pulse is reflected back up towards the boat and is received by the transducer. The depth of an object can be calculated by measuring the time between sending the pulse and receiving its echo. The NAVMAN fishfinder will detect the bottom down to 600 feet (180 metres), depending on the clarity of the water, and the type of transducer used. The strength of an echo can vary for a number of reasons. Larger fish usually return stronger echoes, as so do fish in the middle of the cone, where the pulse is strongest. Reasons for weak echoes include the fish or object being in deep water or turbid water or in the edge of the cone where the pulse is weakest. Turbid water scatters the ultrasonic pulse and is difficult to see through. Turbidity can be caused by air in the water (e.g. from another boat's wake) or by mud in the water.
Assisting with navigation
The NAVMAN fishfinder can be used to find fish, to locate features on the bottom such as reefs or wrecks and to help recognize favourite fishing spots from the profile of the bottom. Use the NAVMAN fishfinder to assist navigation by following the depth contours marked on charts. IMPORTANT NOTE ON USE. While the NAVMAN fishfinder can be used as an aid to navigation, accuracy can be influenced by many factors including the location of the transducer. It is the users responsibility to ensure that the NAVMAN fishfinder is installed and used correctly.

How to find fish

Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the NAVMAN fishfinder to find these features, then look for fish by passing over the feature slowly several times using the ZOOM screen (see section 3-4). Where there is a current, the fish will often be found downstream of the feature. For deep-sea fishing with the FISH 4150, a rapid change in temperature may indicate the edge of a warm or cold current. The temperature difference can form a barrier which the fish may not swim through. Search for fish on either side of the barrier.

Cleaning and maintenance

The NAVMAN fishfinder should be cleaned with a damp cloth or mild detergent. Avoid abrasive cleaners and petrol or other solvents. Always cover or remove a transom-mounted transducer when repainting the hull. If painting over a through hull transducer with antifouling paint then use only one coat of paint. When repainting the transducer, remove previous coats of antifouling paint by sanding it lightly. When not in use, the NAVMAN fishfinder can either be removed from the installation bracket and stored in a safe, dry, cool place such as the NAVMAN carry bag, or left on the installation bracket and securely covered. An optional sun cover, that also prevents key depressions when in place, is available from NAVMAN dealers.

Important

It is vital to the performance of the fishfinder that the transducer is installed in the best location. Please follow the instructions in the Transducer Installation manual very carefully. All of the NAVMAN 4000 Series fishfinders use new proprietary SBN Technology for sonar processing to improve signal enhancement, bottom recognition and noise rejection. SBN Technology uses the latest in digital adaptive filter algorithms to enhance all returned signals.

An internal simulator allows users to learn how to operate the fishfinder off the water. In Simulation mode the word SIMULATION flashes on the bottom of the screen. The fishfinder generates data so that all the main screens appear to be operational. Any changes made to the contrast, backlighting, alarms or the display setup are saved. power supply of 12 V DC to access the Simulation mode. Contact your nearest NAVMAN dealer.
To turn the Simulation mode on, power the fishfinder off, disconnect the blue transducer plug at the rear of unit, then turn the power on. To turn the Simulation mode off, power the fishfinder off, reconnect the blue transducer plug at the rear of the unit, then power the fishfinder on.
Turning Simulation on and off

Recognizing the Type of Fish
Different species of fish have different sizes and shapes of swim bladders. The air in the swim bladder reflects the ultrasonic pulse, so the strength of the echo varies between fish species according to the size and shape of the swim bladder. The sonar display on the FISH 4100 / 4150 is 70 pixels wide, so it can show 70 levels of return echo strength, which is a powerful feature. When fishing among a school of fish and catching them, note the fish species and the strength of the echo that it returns on the fishfinder on the Sonar Echo screen. Then, the next time that particular return on the fishfinder is seen, it is likely to be the same fish species.
Recognizing the Type of Bottom
The bottom trace is the strongest echo shown in the lower part of the left side of the screen. A bottom trace with a wide chequered grey layer is indicative of a hard bottom, because a hard bottom returns strong echoes. Conversely, a soft bottom produces medium or weak echoes, which are shown by a narrower trace.
Adjusting the Shading Bar
The Shading Bar is displayed as a horizontal bar in the lower half of the screen. Use the Shading Bar to choose the strength of the echoes to be displayed in black on the screens. Echoes that are weaker are displayed in black. Increase the black part of the Shading Bar by pressing if there are too few long (strong) echoes being displayed. Decrease the black part of the Shading Bar by pressing if there are too many long (strong) echoes being displayed.

Gain setting

These strong echoes will be shown in chequered grey on the Fish History screen These medium echoes will be shown in black on the Fish History section The weak echoes within this white section of the shading bar will not be shown - they are below the threshold of where the shading begins.

Manual Gain

When Manual Gain is selected, increasing the gain setting will result in more detail being shown on the fishfinder display. Decreasing the gain will reduce detail being shown. See Changing the Gain Mode in section 3-2 for more information on changing Gain settings.
Increasing Gain by pressing will move the black bar to the left and result in weaker echoes being displayed in the Fish History section.

When removing the NAVMAN fishfinder, ensure that the plugs left in the boat are not exposed to the elements. Push the attached dust covers over the exposed ends of the plugs. Keep the display unit in a dry clean place such as the optional NAVMAN carry bag.

5-4 Wiring Connection

Warning
1 Amp fuses must be positioned where shown in the wiring diagrams. If possible, route the transducer cables away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and other electrical equipment can affect the unit. The shortest and most direct connection to the boat's battery helps to minimize voltage drop. Do not lay cable along the bilge. Two wiring options are described in this section: Basic Wiring. This does not start the fishfinder automatically when the boat ignition is switched on and it disables the engine hours counter. Auto Power Wiring. This must be used for engine hours and fuel computer options.

Appendix B - Troubleshooting
This troubleshooting guide is written with the assumption that the user has read and understood the relevant sections in this manual. It is possible in many cases to solve difficulties without having to send the display unit back to the manufacturer for repair. Please follow this troubleshooting section before contacting the nearest NAVMAN dealer. There are no user serviceable parts. Specialized methods and testing equipment are required to ensure that the display unit is reassembled correctly and is waterproof. Users who service a NAVMAN fishfinder themselves will void the warranty. Repairs to the NAVMAN fishfinder may only be carried out by a service centre approved by NAVMAN NZ. If the display unit must be sent into a service centre for repair, it is essential to send in the transducer(s) at the same time. More information can be found on our Website: www.navman.com. 1. The fishfinder won't turn on: a) NAVMAN fishfinders are designed to operate on 12 volt battery systems, where the voltage may vary from 10 to 16.5 volts. If an excessive voltage is supplied to the unit, a resettable fuse will be tripped, turning the display unit off. b) Check that the power cable LT connector at the back of the display unit is securely plugged in and the collar is locked in place. The collar must be secure for watertight connection. c) Measure the battery voltage while the battery is under load - turn on some lights, radio, or other electrical equipment connected to the battery. If the voltage is less than 10 volts: - the battery terminals or wiring on the terminals may be corroded. - the battery may not be charging correctly or may need replacing. d) Inspect the power cable from end to end for damage such as cuts, breaks, or squashed sections. e) Ensure that the red wire is connected to the positive battery terminal and the black wire to the negative battery terminal. If wired for the engine hour option, ensure the yellow wires are connected to the ignition circuit. Also check the boat's main switch circuit. See section 5-4. f) Check for corrosion on the power cable LT connector and clean or replace if required. g) Check fuses that are placed in line with the power cable. A fuse can be blown despite appearing to be good, or the fuse may be

6. Bottom echo disappears or erratic digital reading while the boat is moving: a) Ensure the back of the bottom surface of the transducer is slightly lower than the front and the front is as deep in the water as possible in order to minimize the generation of bubbles through cavitation. See the Transducer Installation Guide for more information. b) The transducer may be in turbulent water. Air bubbles in the water disrupt the echoes returned, interfering with the fishfinders ability to find the bottom or other targets. This often happens when the boat is reversed. The transducer must be mounted in a smooth flow of water in order for the fishfinder to work at all boat speeds. c) Electrical noise from the boats motor can interfere with the fishfinder. Try some suppression spark plugs. 7. If the fishfinder beeps when turned on but nothing is displayed: The fishfinder may be operating, but the contrast settings may have been set too high or low. Power off the fishfinder. Then hold and press to reset the fishfinder to the default contrast setting. 8. The wrong language is displayed: See section 2. 9. The message "NO TRANSDUCER DETECTED. ENTER SIMULATION MODE?" appears when you turn the unit on: a) Check to see that the blue transducer connector is plugged into the top connector (with the blue nut) on the rear of the display unit. b) Check the cable connectors are securely plugged in and the blue collars are is locked in place. The collars must be secure for water tight connection. c) Check that the plugs are clean and free of water or anything that may short deteriorate the quality of the connection. Inspect the transducer cable from end to end for damage such as cuts, breaks, stretched or squashed sections.
