...................................................................................................................................87 Appendix D Compliance statements............................................................................................................................................89 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 Navman 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, official government charts. Only official 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. Sonar performance: The accuracy of the sonar 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 filling 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. Navman 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. 4 8120 Installation and Operation Manual 1 Introduction Quick reference to the built-in and optional features: Feature General Type How to use the keys and windows Troubleshooting Simulate mode Glossary of special names Specifications MOB Man overboard key Navigation Overview of how to navigate Finding the boat's position on the chart Navigate to any point or to a waypoint Navigate along a route Projected course: An estimate of progress Tracks: records of where the boat has been GPS receiver status Saving and loading data with a user card Chart data Chart features (built in world chart) Chart details Tides at a port Alarms Built in alarms SmartCraft engine alarms Boat data Data at top of main displays Compass at top of main displays Dedicated data display Fuel Fuel computer, Instrument petrol/gasoline engine Fuel computer, Instrument diesel engine Fuel computer, SmartCraft engines What to do when you add or remove fuel Sounder Overview of the depth sounder Depth, bottom features, water features Fishfinder Other boats Track your buddy, polling other boats Distress calls See 2 Appendix B 2-6 Appendix C Appendix A 2-4 3-1 3-2 3-1 3-1 3-4 3-5 7 15 3-2 3-2-4 & 5 14 2-5 1-1 2-7-3 2-7-4 12 13 13 13 13-1 9 9 9 16 16 Requires GPS fix User card Chart card Chart card SmartCraft Fuel sensors Diesel sensors SmartCraft Sounder Sounder Sounder DSC VHF DSC VHF 5 8120 Installation and Operation Manual 1-1 Overview The NAVMAN 8120 is a rugged, highly integrated marine chartplotter and fishfinder. It is easy to use and has a very large, easy to read and use colour 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 8120 to receive video from a compatible source, such as a camera. Fuel functions require one or more petrol/gasoline or diesel 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. DSC/Buddy track functions require an appropriate Navman DSC VHF radio to be installed. The 8120 can send data to other instruments, such as an autopilot, and receive data from other instruments. For information on installation options, see section 18-2. This manual describes how to install and operate the 8120. Special terms are explained in Appendix C. For more information on this instrument and other Navman products, go to our website, www.navman.com. 1-2 Cleaning and maintenance The Instrument screen is covered by a proprietary anti-reflection 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. Cover or remove a transom-mounted transducer when repainting the hull. If painting over a through hull transducer with antifouling paint, use only one coat of paint. Remove the previous coat of antifouling paint by sanding it lightly. To optimize performance, avoid walking on or jamming cables and connectors. Keep the transducer free of weed, paint and debris. Do not use a high pressure water blast on a speed sensor paddlewheel as it may damage the bearings. Push the dust cover over the display when the Instrument is turned off. 6 8120 Installation and Operation Manual ! WARNING 1-3 Plug-in cards The 8120 can use two kinds of C-MAPTM SD-Card plug-in cards: Chart cards have chart details required for navigating in a particular region. When you insert a chart card, the extra details automatically appear on the Chart window. You can plug in up to two chart cards at once.

Twenty-four satellites orbit the earth and broadcast position and time signals. The positions of these satellites are constantly changing. The GPS receiver analyses the signals from the closest satellites and calculates exactly where it is on earth. This is called the GPS position. The accuracy of the GPS position is typically better than 10 m (33 ft) for 95% of the time. A GPS antenna can receive signals from the GPS satellites when it is almost anywhere on earth. Differential beacon DGPS Differential beacons are land based radio transmitters that broadcast correction signals that can be received by a special receiver on the boat. Differential beacons are usually only installed near ports and important waterways, and each beacon has a limited range. The accuracy of the corrected GPS position is typically better than 2 to 5 m (6 to 16 ft). GPS receiver Navman 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 first position. Under some circumstances it will take up to two minutes or longer. DGPS A DGPS system uses correction signals to remove some of the errors in the GPS position. The Instrument can use one of two types of DGPS system: WAAS and EGNOS DGPS WAAS and EGNOS are two satellite based DGPS systems. The correction signals are broadcast by satellites and are received by the Instrument's standard GPS antenna. The accuracy of the corrected GPS position is typically better than 5 m (15 ft) for 95% of the time. WAAS covers all of the USA and most of Canada. EGNOS will cover most of Western Europe when it becomes operational. 31 8120 Installation and Operation Manual 8-1 Satellite window The satellite window has information about the GPS satellites and GPS position.

This section explains how to interpret the sonar displays, when and why to use the different frequencies and how fish are detected and displayed. It also describes Gain and Range and shows examples of some of the different sonar displays. 9-1 Using the Instrument The Instrument uses a sonar 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 4800 ft/sec (1463 m/sec), spreading out into a cone shape. When the pulse meets an object, such as a fish or the bottom, it is partly reflected back up towards the boat as an echo. The depth of the object or bottom is calculated by the Instrument by measuring the time taken 32 between sending a pulse and receiving the echo. When an echo has been returned, the next pulse is sent. The Instrument converts each echo into an electronic signal, displayed 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. See sections 17-3 and section 8-2, for more information. 8120 Installation and Operation Manual The appearance of echoes displayed are affected by: · The Instrument settings (see sections 17-3, 8-5 and 8-6) · Echoes (different fish types, different bottom types, wrecks and seaweed; see section 8-2) · Noise (water clarity and bubbles; see section 8-2). Cruise, Fishing and Manual Modes The Instrument has three sonar operating modes: · Cruising mode: Use this when on the move. The Instrument automatically adjusts its settings to compensate for water clarity and to display the bottom. · Fishing mode: Use this when fishing. The Instrument automatically adjusts its settings to compensate for water clarity and to best display fish, the bottom and other details. · Manual mode: Use this to fine-tune the Instrument 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. For more information about modes, see sections 8-5 and ! CAUTION 8-6. ! WARNING Use the automatic Cruising or Fishing DANGER modes when learning to use the Instrument or when travelling at speed. 9-2 Interpreting the display The sonar 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 sonar signal displayed 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 Fast, at depths over 1000 ft (300 m) it takes about 2 minutes for CAUTION A B C D 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 fish information or a shorter history with more fish details (see section 17-3). If the boat is anchored, the echoes all come from the same area of bottom. This produces a flat bottom trace on the window. The screen shot shows a typical sonar window with the Fish symbols turned Off. The sonar pulse generated by the Instrument 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°. The differences in the cone width affect what is displayed. (See section 8-3) A School of fish B Hard bottoms such as rock and coral show as wide bands C Single fish D Soft bottoms such as mud, weed and sand show as narrow bands 8120 Installation and Operation Manual 33 DANGER Strength of echoes The colours indicate differences in the strength of the echo. The strength varies with several factors, such as the: · Size of the fish, school of fish or other object. · Depth of the fish or object. · Location of the fish or object. (The area covered by the ultrasonic pulse is a rough cone shape and the echoes are strongest in the middle.) · Clarity of water. Particles or air in the water reduce the strength of the echo. · Composition or density of the object or bottom. CAUTION 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 sonar pulse, resulting in a weak echo. Hard, rocky or coral bottoms reflect the pulse, resulting in a strong echo. Frequency and cone width Water Depth 25 50 100 150 200 300 400 600 800 1000 Cone width at 50 kHz 20 40 80 130 170 250 330 500 660 830 Cone width at 200 kHz 5 10 20 30 40 60 80 120 150 190 45° cone 11° cone 34 8120 Installation and Operation Manual 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 sonar window in such an environment. A double bottom trace is shown on the window. When looking for fish 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. Example of shadows Sonar window of same area A A B B A B Fish is visible on the window Fish is hidden by the strong echoes off the bottom and is not shown on the window A A 9-3 Single and Dual frequency fishfinding Sonar frequencies The Instrument has two sonar frequencies, 200 kHz and 50 kHz. To select the sonar frequency to use: 1 Go to a sonar window (see section 9). 2 Press MENU , select Frequency and select 200 kHz, 50 kHz,or Mixed. 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 definition display with more shadow compared to the 200 kHz frequency. This means that a group of small fish, for example, could be displayed as a single item, while any fish very close to the bottom 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 identified and then examined in detail with the 200 kHz frequency. 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 definition 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 fish, including bottom dwellers. 35 8120 Installation and Operation Manual When to use Mixed The Mixed frequency combines the 200 kHz and the 50 kHz echoes on one sonar window, filling in detailed echoes in the centre of the sonar cone. When to use 50/200 kHz Operating the Instrument 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 (see section 9-4). A B B A Narrow angle, more detailed 200 kHz cone B Wide angle, less detailed 50 kHz cone 36 8120 Installation and Operation Manual Comparison of the same fish scenario displayed at different frequencies: 1 minute ago 30 seconds ago Now 50 kHz display 200 kHz display 200/50 Khz display Mixed display 37 8120 Installation and Operation Manual 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 (see section 9-2). If there is a current, the fish will often be found downstream of the feature. When fishing with the Instrument with the Fish symbols Off, 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 fish may not swim through. In fresh water, fish often collect around a thermocline. Fish arches In good conditions, a fish passing through the cone-shaped ultrasonic pulse is displayed as a fish arch. The 50 kHz frequency uses a wider cone than the 200 kHz frequency. This makes the fish arches easier to see. A fish arch starts when a fish enters the weak edge of the sonar cone, generating a weak echo that is displayed as the start of the fish arch. As the fish moves closer to the middle of the cone, the distance between the transducer and the fish reduces and the echo is displayed at progressively shallower depths, producing a rising shape. When the fish passes directly beneath the middle of the cone, the echo becomes strongest and thickest. As the fish passes out of the middle of the cone the reverse happens with a progressively weaker and deeper echo. There are many reasons why fish arches may not be seen. For example: · Poor transducer installation (see Transom Transducers Installation Guide). · If the boat is anchored then fish will tend to show on the window as horizontal lines as they swim into and out of the transducer sonar beam. Slow speeds in deeper water give the best fish arch returns. · Range is important. It will be much easier to see fish arches when using zoom mode to concentrate on a particular section of water, rather than just displaying everything from the surface to the bottom. Zooming increases screen resolution and is necessary for good fish arches. Fish symbols The Instrument uses NAVMAN's SBN II technology to analyse sonar echoes and identify which are likely to be fish. The Instrument can be set up to display a fish symbol and the depth over these echoes (see section 17-3, Fish symbols). While SBN II is very sophisticated it is not foolproof - there will be times when the Instrument will not be able to differentiate between fish and large air bubbles or rubbish. Depending on the strength of a fish signal, the Instrument can display a small, medium or large symbol (see section 17-3, Fish filter). To see the maximum amount of information from the echoes, turn Fish symbols off. Fish appear as arches on the window. 38 8120 Installation and Operation Manual · It is difficult to get fish arches in shallow water as the transducer sonar beam is very narrow near the surface and fish do not stay within the beam long enough to display an arch. Several fish in shallow water tend to display as randomly stacked areas of colour. · Wave motion may result in distorted fish arches. 23 Fun fish symbol Normal fish symbol Fun symbol + depth Fish arch + depth 9-5 Range Range is the vertical depth displayed on the Instrument sonar window. For example, if the range is 100 m, then the sonar window shows depths between 0 and 100 m. The range is displayed at the bottom, right corner of a sonar window. The Instrument has two range modes: Auto: The Instrument 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: 1 Go to a sonar window (see section 9). AUTO 2 Press GOTO Manual: The Instrument 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. To set Manual range or to change the range: 1 Go to a sonar window (see section 9). 2 Either press to increase range or press to ! CAUTION decrease range ! WARNING Use the Auto range when learning to use DANGER the Instrument or when travelling at speed. Zoom range and offset CAUTION The sonar Zoom and Bottom windows can show a magnified part of the range (see sections 9-2 and 9-3). 39 8120 Installation and Operation Manual 9-6 Gain and threshold Gain and threshold settings control the amount of detail displayed on a sonar window: Gain: The gain of the sonar 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 displayed. There is a separate gain setting for each sonar 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 displayed. 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 sonar frequency, 50 kHz and 200 kHz. Changing mode The Instrument has three operating modes, In Cruising and Fishing modes, the Instrument 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, Select Mode and then select Fishing, Cruising or Manual. When you select Manual, the Instrument reverts to your last manual settings. Changing gain and threshold 1 In the Gain window, press or to select the setting to adjust. 2 Press or adjust the setting. The Instrument changes to Manual mode. Tip: Use the A-scope window to help set gain or threshold manually (see section 9-5).
