FISH 4500/4600 Installation and Operation Manual

1 Introduction

Congratulations on choosing a Navman fishfinder. For maximum benefit, please read this manual carefully before installation and use. This manual describes how to install and set up the FISH 4500/4600 and the associated dualfrequency transom transducer. (If a through hull transducer is used, refer to the Installation Instructions supplied with that transducer.) This manual also explains how to operate the FISH 4500/4600 effectively and provides troubleshooting information and performance tips.

Important

It is vital to the performance of the fishfinder that the transducer is installed in the best location. Please follow the installation instructions very carefully.
1-1 Benefits of the FISH 4500/4600
The FISH 4500/4600 is a high quality, dualfrequency sonar fishfinder that is supplied with a dual-frequency transducer. It uses TFT (Thin Film Transistor) technology to provide a color display for easy daylight viewing that can be dimmed for night fishing. The bracket mounting option also allows the fishfinder to be tilted and swivelled for optimum viewing. The colors on the sonar displays are customizable, with a choice of four 16 color palettes and one 8 color palette. The colors represent different signal strengths, making the sonar displays easy to interpret. The dual frequency capability enables the FISH 4500/4600 to operate and display: At a high frequency of 200 kHz. At a low frequency of 50 kHz. Both frequencies side-by-side on a split display. Both frequencies combined together into a single display. This capability, combined with a variable power output of up to 600 W RMS, ensures that the FISH 4500/4600 operates effectively in shallow and deep water. The FISH 4500/4600 can detect the bottom to a depth of 2000 feet (600 metres) depending on the clarity of the water, the ultrasonic frequency chosen and the type of transducer used. 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 bottom profile. The Navman fishfinder can also assist with navigation by providing depth information to help identify the depth contours marked on charts. The FISH 4500/4600 is particularly suited to work with the TRACKER 5500/5600 - Navmans color display GPS chartplotter with worldwide coverage. The two instruments can be connected together using either NavBus or NMEA, so they can share data. IMPORTANT NOTE ON USE. While any fishfinder can be used as an aid to navigation, accuracy can be limited by many factors, including the location of the transducer. It is the users responsibility to ensure the Navman fishfinder is installed and used correctly. With the optional fuel kit, the FISH 4500/4600 also becomes a sophisticated and easy-to-use fuel computer. All of the Navman 4000 Series fishfinders use new proprietary SBN-II Technology for sonar processing to improve Signal enhancement, Bottom recognition and Noise rejection. SBN-II Technology uses digital adaptive filter algorithms to enhance all returned signals. At the same time, SBN-II Technology uses active noise control to reject interference, which can often be mistaken by fishfinders for true returns. Using SBN-II Technology, the Navman fishfinder analyses the reflections from each pulse, filters false returns and displays what is in the water under the boat. See section 4-1 Interpreting the display, for more information.

3-8 Setup > Calibrate

Press MENU once or more until the Setup menu is displayed, then select Calibrate: The fuel options can be calibrated only when the optional single or twin engine kit is installed on petrol/ gasoline engines. Use the cursor keys to display the speed readout box, then increase or decrease the readout to match the independent speed value.

Speed Filter

Increase this setting to stabilise an erratic speed reading. Decrease to improve reading responsiveness. The speed filter can be set from 0 to 30 seconds.

Temperature Speed

Calibration may be required because different hull shapes have different flow characteristics. Obtain an accurate measurement of the boats speed from a GPS receiver; or by following another boat travelling at a known speed; or by making a timed run over a known distance. Note: for accurate calibration: The speed from a GPS receiver should be greater than 5 knots. The speed from another paddlewheel transducer should be between 5 and 20 knots.
The factory settings should be sufficiently accurate for normal usage. To calibrate the temperature readout, first measure the water temperature with a thermometer known to be accurate. Use the cursor keys to display the temperature readout box, then increase or decrease the value to match the measured temperature. The temperature can be set from 32 to 99.9F (0 to 37.7C) with a resolution of 0.1 unit. To change the units between F (Fahrenheit) or C (Celsius), see section 3-6 Setup > Units.

Temp filter

Increase this setting to stabilise an erratic temperature reading. Decrease to improve reading responsiveness. The temperature filter can be set from 0 to 30 seconds.
Best results are achieved in calm conditions where there is minimal current (best at high or low tide).

Fuel Warning:

Extreme precautions must be observed when carrying out this procedure. Failure to do so could create hazardous conditions that can cause serious personal or property damage.

Keel offset

Keel offset is a depth correction representing the vertical distance between the depth transducer and the location from which the depth is to be measured. Enter a positive keel offset value when the transducer is located below the water surface but the total depth is required. Enter a negative keel offset value when the depth below the deepest part of the boat is required (such as the keel, the rudder or the propeller) and the transducer is located closer to the water surface. Use the cursor keys to select Keel offset, then press to display the Keel offset box. Use the or cursor keys to adjust the value.
Calibrating the fuel usage can improve the accuracy of fuel measurements. Twin engine installations require each fuel transducer to be calibrated. This can be done at the same time with two portable tanks or at different times using one portable tank. Calibrating the fuel transducer(s) 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 difficult to fill underfloor tanks to the same level twice due to air pockets, so the more fuel used, the more accurate the calibration. To calibrate the fuel transducer(s), perform the following steps: 1. Record the level of the fuel in the tank(s). 2. Connect the portable tank(s) to the engine through the fuel transducer(s). 3. Run the engine at normal cruising speed until at least 4 gallons (15 litres) of fuel has been used per engine. 4. Check the actual amount of fuel used per engine by refilling the portable tank(s) to the original level and noting the reading(s) from the fuel dispensers gauge. 5. Select Fuel. Use the cursor keys to change the reading for each engine to match that on the fuel dispensers gauge. 6. Press ENT when the reading is correct. Note: If the fuel calibration options appear to give erroneous readings after a while, first check that the fuel sensor has been installed correctly according to the installation instructions supplied with it. Then see Appendix B - Troubleshooting.

4 Using the FISH 4500/4600
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. Also see section 1-2 How the FISH 4500/4600 works.
4-1 Interpreting the display
The sonar displays 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 on 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 display 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 4 minutes for each vertical line of pixels to move across the display, whereas at 20 ft. (6 m) it takes only about 15 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 3-2 Setup > Sonar. If the boat is anchored, the echoes all come from the same area of bottom. This produces a flat bottom trace on the display. The screen shot shows a typical sonar display with the Fish symbols turned Off.

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 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. Note: 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. Kelp / Weed Soft bottoms such as mud, weed and sand show as narrow bands Hard bottoms such as rock or coral show as wide bands
Single fish Large school of fish Small school of fish Bottom

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. See section 5-3 Sonar Bottom display.

Frequency and cone width

The pulse generated by the FISH 4500/4600 transducer travels down through the water, spreading outwards to form a rough cone shape. However, the cone width is dependent upon the frequency of the pulse; at 50 kHz it is 45, whereas at 200 kHz it is 11. The chart shows how the cone width varies over depth for each frequency used. Figures are approximate. Depth

The fish symbol can be customized or switched off altogether so that the echoes are not converted to fish symbols on the display. See section 3-2 Setup > Sonar. The differences between Fish symbol On and Off are:

Fish symbols On

Using Navmans SBN-II sonar technology the fishfinder analyses all echoes and eliminates most false signals and clutter so that remaining targets are most likely fish. Depending on the strength of the remaining echoes, they are displayed as either small, medium or large fish symbols - with or without depth. While the SBN-II processing is very sophisticated it is not foolproof - there will be times when the fishfinder will not be able to differentiate between large air bubbles, rubbish containing air, fishing floats etc. and genuine fish. The following picture shows the Sonar display with the Fish symbol: On + depth:

4-4 Gain

Gain (sensitivity) controls the amount of detail displayed on the FISH 4500/4600. Understanding how to set suitable Gain settings is important for optimum performance. The Navman fishfinder has two gain modes, Auto Gain and Manual Gain. Normally the best results are obtained in Manual Gain, but practice and experience are required to obtain the optimum settings for different conditions. Therefore, the use of Auto Gain is strongly recommended when learning to use the fishfinder or when travelling at speed. In Auto Gain, the gain adjusts automatically to compensate for water depth and clarity. In Manual Gain, the gain can be adjusted by the user to compensate for water depth and clarity. High Gain settings may amplify the normal background noise until it appears as random pixels.
Note: The Gain mode automatically changes to Manual Gain if the gain or threshold settings are adjusted by the user
Obtaining the best results
To obtain the best detection capability for both fish and bottom we recommend the use of the Sonar A-Scope display: 1. Set the threshold to 0%. 2. Adjust the gain until the threshold line is just to the right of the unwanted noise.
Changing between Auto and Manual
To change between Auto Gain and Manual Gain: 1. From any Sonar display, press ENT. 2. Use the or cursor keys to highlight Auto or Manual, then use the or cursor keys to select the required mode.

Divider line between sonar history and A-scope Gain setting (strongest echo for display) Gain threshold (weakest echo for display) See section 4-4 Gain, for more information. The strength of an echo at a particular depth is shown by the length of the horizontal line at that depth. A strong echo produces a long line whereas a weak echo produces a short line. To change items, press MENU until the Options menu is shown. Gain is explained in section 4-4 Gain. Range is explained in section 4-5 Range. Data header is explained in section 5-1 Sonar display. Split ratio is explained in section 5-2 Sonar Zoom display.

Fish recognition

The echo strengths shown on the A-scope can be useful in recognising 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 user can define the level of the weakest and strongest echoes to be shown on the sonar displays, by using the Gain and Threshold settings.
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 A-scope. Then,
when that particular echo is seen at future times on the fishfinder, it is likely to be the same fish species.

5-6 Fuel display

Used shows total fuel used since this was last reset with the Clear Used command. Remaining shows the amount of fuel remaining in the tank(s). Flow shows the fuel consumption per hour. For twin engine installations, the fuel flow for each engine is shown separately. This is useful for checking that both engines are under the same load. Economy is the distance travelled per unit of fuel used. The Fishfinder calculates this using the fuel used and boat speed (water speed or GPS speed - which ever is selected as the speed source see section 3-3 Setup > Fuel). To show the Fuel display, press DISP and select Other Tab, select Fuel and press ENT. There are no options. (See section 3-3 Setup > Fuel for information about setting up the fuel values. If the number of engines is set to 0, the fuel features are turned off.) The bigger this number, the better the fuel economy. Adjust the throttle and trim to achieve the best fuel economy. Note: when water speed is selected as the speed source, calibration of the boat speed measurement is essential for an accurate fuel economy reading see section 3-8 Setup > Calibrate. To show the Data display, press DISP and select Other Tab, select Data and press ENT. This shows a graph of the water temperature and depth over the last 20 minutes and selected data items. The graph is useful for locating warm and cold spots in the water. To change data items: 1. Press MENU until the Options menu is shown. 2. Highlight Data setup and press ENT. 3. Use the cursor keys to move from data field to data field. 4. Press ENT at any data field to show the list of data items that can be displayed there. 5. Highlight the required data item and press ENT. The data item is immediately displayed. 6. Press ESC when finished.

Secondary alarm wiring option
Green Wire: Use this to connect a secondary alarm indicator such as a flashing light or external beeper with a built-in drive circuit. See the Auto power wiring diagram. If the external beeper or light requires more than 200 mA total, fit a relay. Consult your Navman dealer for more advice.

Fuel kit wiring

See the Fuel Kit Installation Guide for information about the fuel transducer cable. Wire the power cable for Auto power (as described in this section) to make sure the fuel counter starts as soon as the engine starts. For twin engine installation a T-connector needs to be installed on the fuel transducer cable.

Comms wiring

NMEA wiring option: NMEA out: White wire - Use this, if desired, to connect the Fishfinder to other NMEA instruments such as Navmans REPEAT 3100. (See section 6-6 Systems of several instruments.) NMEA-1 in: Blue wire Use this, if desired, to connect a NMEA instrument to the Fishfinder such as an external GPS source. Note however, to use NMEA-1 in, NavBus must be disabled in the Comms menu see section 3-7 Setup > Comms. NavBus wiring option: NavBus (-): Blue wire: and; NavBus (+): Orange wire: Use this, if desired, to connect the fishfinder to other Navman instruments such as Navmans REPEAT 3100. (See section 6-6 Systems of several instruments.)
NMEA and NavBus option: If both NMEA and NavBus are to be used, then use the following: NMEA out: White wire - NMEA out NMEA in: NMEA-2 in (White connector) NavBus: Blue wire - NavBus(-) and Orange wire NavBus(+) In all cases, both NMEA and NavBus reference to Black wire (GND)
6-6 Systems of several instruments
Several Navman instruments can be connected together to share data. The FISH 4500/4600 is particularly suited to work with the TRACKER 5500/5600 - Navmans color display GPS chartplotter with worldwide coverage. There are two ways of connecting instruments together; NavBus or NMEA. of instruments. Then, if the backlight setting is changed in one group, it will automatically change for the other instruments in that group. However, the backlight setting will not change for instruments in different groups.

If an alarm sounds, mute it by clearing the
alarm on any instrument which can display that alarm.
NavBus is a Navman proprietary system that allows systems of multiple instruments to be built using a single set of transducers. When instruments are connected by NavBus:
If the units, alarms or calibration are changed
NMEA is an industry standard for marine instrument connections. Data sent by one instrument over an NMEA line can be read and displayed by another instrument that accepts NMEA 0183 Version 2. It is not as flexible as NavBus as it requires dedicated connections between instruments. Please contact your Navman dealer for information on Navmans full range of NMEA enabled instruments and connection options.

6-7 Cleaning and maintenance
The FISH 4500/4600 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. 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. When not in use, the FISH 4500/4600 can be removed from the installation bracket and stored in the Navman carry bag, or left on the installation bracket and securely covered with the sun cover supplied.

Appendix C - 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 the product themselves will void the warranty. Repairs to the product may only be carried out by a service centre approved by Navman. If the product 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 wont turn on: a) The FISH 4500/4600 is designed to operate on a 12/24 volt battery system, where the voltage may vary from 10 to 35 volts. If an excessive voltage is supplied, a fuse will be tripped, turning the display unit off. Check the fuse. b) Check that the power cable 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, squashed or trapped 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 Auto Power option, ensure the yellow wire is connected to the ignition circuit. Also check the boats main switch circuit (see section 6-5 Wiring options).

Check for corrosion on the power cable connector and clean or replace if required. 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 corroded. Test the fuse or replace it with a fuse known to be good. The fishfinder wont turn off: The fishfinder may have been wired for Auto power. In this case, the fishfinder cannot be turned off while the ignition power is on. (See Auto power wiring in section 6-5 Wiring options.) The fishfinder operates erratically: Check that the transducer does not have debris (e.g. weed, plastic bag) caught around it. The transducer may have been damaged during launching, running aground or while underway with debris etc. If the transducer has been impacted, it may have been kicked up on the bracket. If it is not physically damaged, reset the transducer back to its original position. (See the Transom Transducer Installation Guide.) When the transducer is less that 2 ft. (0.6 m) from the bottom, the depth readings may become inconsistent and erratic. Manual Gain may be set too low, which may cause weak bottom echo or no fish signals. If in Manual Gain, try increasing the Gain. 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 Transom Transducers Installation Guide.) Check the transducer and power cable connectors at the back of the display unit are securely plugged in and the collars are locked in place. The collars must be secure for watertight connection. Inspect the power cable from end to end for damage such as cuts, breaks, squashed or trapped sections. Ensure there is not another fishfinder or depth sounder turned on, which may interfere with this fishfinder. Electrical noise from the boats engine or an accessory may be interfering with the transducer(s) and/or the Navman fishfinder. This may cause the fishfinder to
