Installation on Bracket
Mounting the Display Unit Standard Mount
You may mount the display unit on any flat surface using the bracket supplied. See Fig. 2-10. (There is also an optional kit which allows you to flush-mount the display in a flat panel or dashboard). Follow these instructions if you are using the standard mounting bracket: 1. The LCD type display used on this unit is easier to see from certain angles. Before selecting a permanent mounting location, make temporary power connections and turn on the unit. This will allow you to test the visibility of the display from several different angles. Remove the display unit from the bracket by pressing on the large button in the center of the bracket. See Fig. 2-10. Mount the base of the bracket using the supplied screws. Slide the display unit back into the bracket. Adjust the display unit for the best viewing angle. You can turn the display from side to side, and tilt it up or down.

Mounting the Display Unit Flush Mount
In order to do this installation, you will need the optional flush mounting kit (part no. M99-138). See Fig. 2-12. 1. Select a mounting location on the dashboard or control panel. Choose a clear, flat area at least 7" x 7" (180 mm x 180 mm). Be sure you will also have at least 6" (152 mm) of clearance behind the area where the display unit will be mounted. It is a good idea to drill a small pilot hole in the center of the mounting area. Be sure there are no hidden electrical wires or other items behind the point where you plan to mount the display unit. A mounting template is supplied with the flush mounting kit. Tape this over the selected location on the panel and trace around the edges. Make the cutout for the display. Drill a series of 1/2" (13 mm) holes at the points shown around the edges of the cutout area. Drill the two small holes for the threaded studs as shown on the mounting template. Use a 7/32" (5.5 mm) drill bit. Remove the template and draw straight lines between the 1/2" holes. Cut along each of the lines with a small saw.

Flush-mount Installation

Separate the display unit from the mounting bracket. (See Fig. 2-13.) Press the large button in the center of the bracket to separate the bracket arms. The display unit is attached to the arms by two screws. Each screw is covered by a cap. Locate the small slot beside each cap and pry upward using a small screwdriver. Remove the caps, then the two screws and the two wave washers. Save these parts in case you ever want to use the mounting bracket.
To pry up the cap, insert a small screwdriver here.

Disassembling from Bracket
Screw the threaded studs into the holes on the rear of the display unit. Set the display unit into place to be sure that it will fit correctly. Thread the wing-nuts onto the threaded studs to hold the display unit in place temporarily. Once the DC wiring is complete, finish the installation. Hold the gasket in place around the opening. Fit the display into the cutout again. From the rear, screw the thumbscrews securely onto the threaded studs to hold the unit in place.
Installing the Transducer Cable
A 20 foot length of cable, with the connector attached, is supplied with the Downlooker transducer.

Fig. 2-14

Installing Cable on Transom
Route the cable up and over the top edge of the transom. See Fig. 2-14. Secure the cable using cable clamps. (These clamps are available from your local marine equipment supplier.) If you do not want to expose the cable on the deck, you may drill a new hole (3/4" or 19 mm) through the transom for the cable. (Rememberthis hole must be large enough to accept the cable with the connector attached. Do not cut the cable!) To seal the opening, use a feed-thru cap where the cable passes through the transom. Run the cable through the interior of the boat. If the transducer cable runs near another electrical wire, it may pick up electrical interference or noise. To reduce this, try to keep the transducer cable separated as far as possible from all other wires. This is especially important with wiring for the boats ignition, alternator, or tachometer. Also try to keep the transducer cable away from the antenna and power cables for VHF or FM radios. It is also helpful to keep the transducer cable away from the FishFinder power cable. If it is necessary to run the transducer cable across any wires, make the crossing at a right angle. Be careful not to tear the cable jacket when passing it through bulkheads and other parts of your boat. Secure the cables in place using tywraps or lacing twine. Coil the extra cable and tie it out of the way. If the 20 foot transducer cable is not long enough, a 15 foot extension cable (5M) is available from your Raymarine dealer (part no. M99-140).

When you attach the extension cable, be sure that the connections are tight and watertight. Use Dow Corning DC-4 or an equivalent sealing compound to protect the connector assemblies. At the rear of the display unit, plug in the transducer cable using the keyed connector.
Installing the Transducer Cable Sidelooker Option
1. If the installation includes the optional Sidelooker transducer, there will be two transducer cables. See Fig. 2-15. The cable from the Sidelooker includes a Y connector, and is 12 long (3.6 m). Plug the cable from the depth transducer into the open end of the Y connector.

Installing the Transducer Cable Installation with Separate Speed and Temperature Sensors
1. Optional depth-only and speed- and temperature-only transducers are available for the FishFinder L470. In this optional configuration the separate transducers are connected via a Y type receptacle cable located on the optional speed- and temperature-only transducer cable.
Plug the cable from the depth-only transducer into the receptacle connector on the optional speed- and temperature-only transducer. The speed- and temperature-only transducer then connects at the transducer receptacle of the FishFinder L470. This is shown below in Fig. 2-16.

Making the DC Power Connections
1. The display unit is designed for use on boats with 12V DC power systems. (The unit can operate as long as the DC voltage is between 10.8 and 16V DC.) The display unit can be wired to a negativeground system, or both the negative and positive supply lines may be floating above ground. This unit is not intended for use on boats with positive ground. The 6-foot power cable supplied with the display unit should reach the source of DC power. On a small boat, connect the power leads directly to the main battery isolation switch or breaker. On a larger boat, route the power leads to the DC power distribution panel. It is very important that you connect the power leads correctly. See Fig. 2-17. At the power source, connect the red wire to the positive

higher value for Speed Cal. If the display unit is reading high, use a smaller number for Speed Cal. You may enter any value between 75 and 125. The temperature sensor is usually very accurate, but you can adjust the calibration using the entry for Temp Cal.
Final note: After you finish the installation, please remember to fill out the Warranty Card included with this manual.

The FishFinder is designed to be easy to use while the boat is moving. You can steady your hand by gripping the right side of the display with the fingers of your right hand. This will allow you to use your right thumb to press the buttons on the display. Notice that some of the buttons can be used in two ways. They do one job during a normal display, and a different job when you are setting up the unit. In this section, we will use symbols like this PWR and SETUP to indicate the buttons on the front of the unit. PWR This button turns the power on and off. To turn on the power Press once to turn the power on. To enter the Lamp/Contrast Menu To bring up the Lamp/Contrast Menu in any operating mode, press the PWR key for a moment, then release it. To turn off the power If you press and hold the button, the display will say Powering Off. If you hold the button for more than 3 seconds, the display unit will switch off.

Fig. 3-4
Figure 3-4 shows a typical FishFinder display. (The FishFinder Page is also called the chart or bottom graph display.) As time passes, this display scrolls from right to left. The scrolling image becomes a record of the echoes and the bottom seen by the FishFinder as your boat moves. The images at the right side of the display show the most recent echoes. Some of these echoes indicate fish, and others show the bottom. As new echoes are received, the FishFinder draws a graph of the bottom. The bottom graph helps you to tell whether the bottom is rising or falling. It also allows you to identify the shape or structure of the bottom. This can indicate a reef or shipwreck. Notice that the scrolling speed of the display does not necessarily match the speed of the boat. The scrolling speed of the display is called the
chart speed. You can adjust this using the Setup Menu. (See Section 4.) Many of the items on this display appear in the other display pages. Since you are likely to use the FishFinder Page most often, we will explain all of these items here.
Top of display Buzzer symbol This symbol shows whether any of the alarms will use the buzzer. There are three kinds of alarms: shallow, deep, and fish. If one of these alarms is triggered, the unit will present a flashing symbol on the display. The Buzzer symbol shows whether, in addition to the flashing symbol, the alarms will also use the buzzer.
If the Buzzer setting in the System Setup Menu is on (indicating that the buzzer is enabled for all of the alarms), this symbol will appear filled. If the Buzzer setting is off (indicating that the buzzer is disabled for all of the alarms), this symbol will be empty. Shallow alarm set You can set an alarm to go off if the boat moves into water which is shallower than a certain depth. If you set this type of alarm, the S indicator will appear on the display. If the alarm is triggered, the S symbol will flash. If the buzzer has been turned on (in the System Setup Menu), the buzzer will also sound. To stop the buzzer, press the CLEAR button. The S symbol will continue to flash until you move into deeper water. Deep alarm set You can set a different alarm to go off if the boat moves into water which is deeper than a certain depth. When this alarm is set, the D symbol will appear. If the alarm is triggered, the D symbol will flash. If the buzzer has been turned on (in the System Setup Menu), the buzzer will also sound. To stop the buzzer, press the CLEAR button. The D symbol will continue to flash until you move into shallower water.

Depth markers These markers show depths between the surface and the full depth range. In this example, the unit is set for a depth range of 100 feet. This means that each of the depth markers shows an interval of 20 feet. Speed This entry shows the speed of the boat through the water. From the System Setup Menu, you can turn this item off or change the units used for this display.
Log/distance This shows how far the boat has traveled since the log was last reset. From the System Setup Menu, you can turn this item off or change the units used for this display. Water temperature This entry shows the current water temperature at the surface of the water. (The reading for water temperature can be helpful for finding fish. A particular type of fish will often prefer water in a narrow temperature range.)
From the System Setup Menu, you can turn this item off or change the units used for this display. Fish symbol This indicates that the FishFinder sees a fish. Generally, the larger the fish symbol appears, the larger the fish. (The size of the fish symbol actually depends on a number of factors. See the section on Fish Indications.) If the fish is detected using the narrow 200 kHz beam, the display will show a filled-in symbol. If the fish is detected by the wide 50 kHz beam, the display will use a hollow symbol. (For more on this, see Choosing the Frequency.) Fish depth This indicates the depth of the fish shown by the fish symbol. This number will be shown using the same depth units (feet, fathoms, or meters) you have selected on the System Setup Menu. The fish depth indicator is turned off when the fish symbol function is off.
Bottom of display Bottom indication This shows the bottom of the lake or sea. You can compare this to the range depth shown in the lower right-hand corner. (In this example, the checkered pattern shows the unit is getting a strong echo return from the bottom. See the information on the White Line feature in the Setup Instructions.)
Range The range is the maximum depth the unit is set to measure. In this example, this is 100 feet. You can set the range manually, or the FishFinder can do it automatically.
Bottom depth This is the depth of the bottom shown on the display. You can select FT (feet), FA (fathoms), or M (meters) using the System Setup Menu. If the FishFinder cant tell how deep the water is, the last known depth flashes on the display. This will continue until the unit can see the bottom again. Before we explain the other pages, there are some general things you should know about the operation of the FishFinder.

Choosing a Frequency

We said that the FishFinder uses sound waves to see through the water under the boat. The frequency is a measure of how fast the sound waves change or vibrate. The FishFinder uses sound waves with two different frequencies 50 kHz and 200 kHz. Raymarine uses these two frequencies because each is better for a particular purpose: 50 kHz frequency Scans a wide area Penetrates water well, good for deep water 200 kHz frequency Scans a narrower area, but produces a more detailed view Good for seeing fish near the bottom or fish close together Better for use in very shallow water
Dual frequency (both 50 kHz and 200 kHz at once) Has the advantages of both frequencies Good depth penetration Good detail in display Using the Dual 50 kHz setting, the display is produced using the signal from the 50 kHz beam, with additional information from the 200 kHz beam. Using the Dual 200 kHz setting, the display is produced using the signal from the 200 kHz beam, with additional information from the 50 kHz beam. If you are using one of the dual frequency settings, you can get some useful information from the fish symbols. If the fish is spotted by the narrow 200 kHz beam, the fish symbol will be black or filled-in. If a fish is detected by the wide 50 kHz beam, the symbol will be hollow. When the unit is first turned on, it is set to use the Auto frequency feature. When set this way, the unit begins by using the 200 kHz frequency. If the bottom depth increases to more than 250 feet (or 50 fathoms or 80 meters), the unit will automatically switch to the 50 kHz frequency. If the unit cannot find the bottom, it will try both the 200 kHz and the 50 kHz frequencies. The unit will then use the frequency which finds the bottom first.

Fish Indications

Even using advanced sonar technology, it is sometimes hard to detect a fish in the water. The body of a fish is just a little more dense than the surrounding water. There is really nothing very solid for the sound waves to bounce off of. The FishFinder L470 is very good at telling the difference between a fish and the surrounding water. In fact, Raymarine is the leader in this technology. When the FishFinder detects a fish, it can be indicated by a fish symbol on the display. In general, a larger symbol means a larger fish. This rule is not always true, though. Lets say that there are two fish of the same size: one is close to the surface, and the other is near the bottom. The fish which is close to the surface will have a larger symbol. This is because the fish which is closer returns more of the sound waves back to the FishFinder. Actually, the sound waves are usually reflected by the air sac near the center of the fish, and not by the body of the fish. The size of this air sac is different for different kinds of fish. This can also affect the size of the

The optional Sidelooker transducer transmits two acoustic beamsone to the port side of the boat, and one to the starboard. These are displayed on the left and right halves of the Sidelooker Page. See Fig. 3-9. Once the Sidelooker feature has been turned on, you can reach the Sidelooker page easily. Press the < or > buttons on the Page Control Pad until the Sidelooker Page appears. The unit will present a display similar to Fig. 3-10.

Boat symbol Side range

Bottom/ shore indication Dashed vertical line

Fish indication

Fig. 3-10
The Sidelooker Page, like the FishFinder Page, displays a graph or chart. The scrolling vertical dashed line represents the centerline of the boat. As new Sidelooker echoes are received, the new information appears at the top of the display, and older information moves towards the bottom. There is no relationship between the chart speed of the FishFinder and the speed of the boat. (The speed at which the display moves is set by the entry for chart speed in the Setup Menu.) When the Fish Symbol feature is turned off, any fish detected will appear as long, vertical lines. These will be slightly arched towards the center of the display. The unit can also be set to display fish symbols, but the fish arches are usually more helpful. The Sidelooker transducer transmits at the 200 kHz frequency. If the unit spots any fish while the Fish Symbol feature is on, they will be indicated by solid fish symbols. (You can turn the Fish Symbol feature on or off from the System Setup Menu. See Section 4.)
Underwater objects such as submerged tree stumps or rocks can also be detected by the Sidelooker transducer. These objects usually appear as thicker vertical targets. The Sidelooker sounding beam is transmitted very close to the surface of the water. In rough or choppy water this turbulence may appear on the Sidelooker display as noise or clutter. The Sidelooker will also display noise or clutter when your boat travels at high speeds or in very shallow water. For best results, use the Sidelooker at idle or slow trolling speeds. On the Sidelooker Page, you may select one of three views using the Sidelooker View option in the Setup menu. These are labeled F, G, and H to match the three Window options which include Sidelooker views. View F looks only to the port (left) side of your boat. The boat symbol appears at the top of the display and the dashed vertical line appear on the right side of the screen. View G looks to both sides of your boat. The boat symbol appears at the top of the display and the dashed vertical line appears in the center of the screen. View H looks only to the starboard (right) side of your boat. The boat symbol appears at the top of the display and the dashed vertical line appears on the left side of the screen. Here are the special items on this display: Boat symbol This is pointing forward on the screen to indicate that, on the Sidelooker Page, the view is from above, as seen from a birds-eye. The boat symbol will appear on the top left, center, or right, depending on the view selected (F, G, or H) in the Sidelooker View option in the Setup Menu. Dashed vertical line The scrolling vertical line is drawn under, or behind, the boat symbol to indicate the division between the information produced by the left and the right sidelooker transducer elements. This is the maximum distance the unit will be able to see using the current range setting. Remember that the sound waves move out at a shallow angle, so this distance is

The normal display on the FishFinder is a top-down view, as if it was seen from the surface of the water. The Bottom Lock Mode shows a bottom-up view. The bottom is used as a reference, and all depths are measured up from the bottom. You can reach the Bottom Lock Mode at any time by pressing the LOCK button. For a moment, the display will say, ENTERING BOTTOM LOCK, then the Bottom Lock image will appear. Figure 3-15 shows the FishFinder Page with the split Bottom Lock feature enabled. The right section of the split image shows a section of the normal FishFinder Page. The left section shows the Bottom Lock image. Bottom indication The actual surface of the bottom under your boat varies in depth and contour. The bottom lock feature flattens out the bottom image to give you greater visibility of fish targets or structure resting on or near the bottom. On the Bottom Lock image, the bottom itself is shown as a flat surface, and all targets are shown relative to this flattened bottom. When using Bottom Lock, you will probably want to keep the Range (not the Bottom Lock Range) set to Auto. If the Range is set to Manual, and the bottom moves deeper than
the selected range, then Bottom Lock will not display the bottom image. Bottom Lock Range The range for the Bottom Lock image is set independently from the master range setting for the FishFinder. This Bottom Lock Range is measured up from the bottom, rather than down from the surface. The Bottom Lock Range may be adjusted using the Setup Menu when the Bottom Lock feature is enabled. (See page 73). The current setting for the Bottom Lock Range is shown in the upper right corner of the Bottom Lock image. This number is the maximum distance above the bottom the unit will display on the Bottom Lock image. (If the Bottom Lock Range number is larger than the actual depth of the water, the unit will not show any target in water shallower than the transducer itself.) The Bottom Lock feature may be used with a split screen presentation or in a full-screen presentation. You can make a selection from the Setup menu. See page 74 for details.

order will be different if you start from the Zoom or Bottom Lock Modes.) To move from one menu item to another, press the and V arrows of the Page Control Pad. (If you continue to press and V often enough, you will eventually return to the same menu item which appeared originally.) The unit remembers which menu item was last used for each page, and will display that item the next time you go to the Setup Menu. To return to the normal display, press CLEAR. (The menu will disappear on its own in seven seconds). This arrangement allows you to reach any item on the Setup Menu easily, make a change, then return to the normal display quickly.

Range Setting

Fig. 4-2
See Fig. 4-2. The range sets the maximum depth the unit will be able to see. Use the < and > arrows of the Page Control Pad to select Auto or Manual range. The Range menu item for the downlooker is available from all pages except the Digital Page and the Sidelooker Page. (The Sidelooker Page does have a Range menu item, but only for the Sidelooker.) Auto range The FishFinder can be set to select the range by itself, automatically. The unit chooses the shallowest range which will still include the bottom in the display. If the bottom rises or falls, the FishFinder will adjust the range to keep the bottom in the display.
Manual range You can also set the range yourself. (However, if the bottom rises or falls, the FishFinder will not adjust for this.) As soon as you select Manual, the cursor will jump down a
line so you can choose the range you want. Use the < and > arrows of the Page Control Pad to make a selection. Here are the choices: Possible Range Settings (Auto or Manual) In feet: 5, 10, 15, 20, 30, 40, 50, 60, 80, 100, 150, 200, 250, 300, 400, 600, 800, 1000, 1500, 2000, 2500

To select the next menu item, press the V arrow of the Page Control Pad.

Sensitivity Setting

Fig. 4-3
The sensitivity adjusts the ability of the unit to tell the differences between echoes of different strengths. In general, the sensitivity should be as high as possible, to detect the fish and show the detail on the bottom. However, if the sensitivity is too high, the unit will begin to see bubbles in the water, debris, and other background noise. Use a higher sensitivity setting for deeper water, and a lower setting for shallower water. The L470 FishFinder has separate sensitivity settings for the 50kHz, 200kHz, and Sidelooker channels. On the bar graph below Auto/Man, the number 200 shows that the sensitivity for the 200kHz signal is being adjusted. 50 shows that the sensitivity for 50 kHz is being adjusted. If

Digital Setup Menu Item
When you are viewing the Window Page, press SETUP. The unit will present the setup menu shown in Fig. 4-14. The first five options (A through E) will appear every time you see this menu. The last three items (F through H) only appear when the optional Sidelooker feature is turned on. We explained the choices in the material on the Window Page in Section 3. (See page 41 and Fig. 3-8.) To make a choice, use the < or > controls, then press CLEAR to save the change. Notice that these options only control the information presented on the left side of the display. In each case, the right side presents part of the normal display. This will include the FishFinder Page, and may also use the Zoom, A-Scope, or Bottom Lock Modes. Notice that, whenever you use one of the last three options (F, G or H), the Digital information disappears. All of the space on the left side of the display is taken up by the Sidelooker Mode. See Fig. 4-20.

Cleaning Instructions

Always keep the display unit clean. Use a soft, clean cloth to wipe off the display panel. Do not use abrasive cleansers, chemical cleaners or solvents. Use a glass cleaner or a suitable general-purpose detergent. If you operate your boat in salt water, you will have to protect the hull with antifouling paint. Use caution when sanding or cleaning the outside of the hull near the transducer. Harsh cleaning solvents such as acetone may damage the transducer. Sea growth can collect quickly on the bottom of the transducer. This can reduce the performance in just a few weeks. To prevent this, coat the bottom of the transducer with a thin layer of paint. Use only a water-based antifouling paint, or a water-based paint specifically designed for transducers. Apply it with a brush. If your transducer becomes fouled or stops working because of sand or sea growth, use a stiff brush to clean it. You may sand the surface with a fine-grit wet or dry sandpaper (#320 grade or finer), but this will affect the performance of the unit when the boat is moving at higher speeds. The paddle wheel mechanism may become jammed by dirt or grit. Work this out of the mechanism, then clean the unit with soap and water or alcohol.
Troubleshooting Suggestions
If the unit is not working correctly, there may be a simple cause. Before you call for service help, please check these points: The FishFinder display unit will not turn on 1. The unit may actually be operating, but the contrast may have been set to the full light or full dark setting. With the unit turned off, hold the CLEAR button. When you press PWR to turn the unit on, all settings
Maintenance and Troubleshooting
will change to the factory defaults. See the default settings on page 82. If the power wiring includes a fuse, it may be blown. Also check the circuit breaker or main battery switch. You may have reversed the power connections. Follow the DC power lines all the way back to the battery. The red wire should connect to the positive terminal (+) on the battery or power source, and the black wire should connect to the negative terminal (-) (also called ground or earth). If the polarity is not correct, reconnect the leads properly and check again. The battery or DC power source may not be producing the correct voltage. The FishFinder needs at least 10.8 volts to operate. If the voltage is lower, check for loose or corroded connections, or a problem with the power source.
The display unit freezes (temporarily or permanently) 1. Check that the display has not been stopped using the Chart Speed Menu Item. (If the adjustment bar is moved all of the way to the left, the display will freeze.) 2. A source of electrical noise may be interfering with the units operation. Both the transducer cable and the power cable for the FishFinder should be routed as far as possible from all other wiring on the boat. To locate the source of the noise, turn on the FishFinder. Next, turn on each electrical device on the boat, but just supply power to one device at a time. This may reveal the cause of the problem. Move the FishFinder, the other unit, or the wiring. A movement of just a few inches can make a big difference. If it is necessary to cross any wires, make the crossing at a right angle. Start the motor in neutral and increase the RPM speed. This can reveal a problem with the wiring for the boats ignition, alternator, or tachometer. It may help to use resistor-type spark plugs or spark plug cables on the boats motor. You can also try a noise-suppression filter on the alternator. 3. One of the wiring connections may be loose. All of the connections should be clean, tight, and insulated. Soldering is the best way of making these connections. Protect each connection with a piece of shrink-wrap tubing.

The display disappears or is unreliable when the boat is moving at high speeds 1. Increased turbulence around the transducer may be confusing the unit. Move the transducer to a location where there is less turbulence when the boat is moving. 2. If the FishFinder is using the Auto Sensitivity setting, it may be reacting to an increase in electrical noise. As the level of noise increases, the sensitivity automatically adjusts, and the unit can lose its ability to see the bottom or fish. Check for problems with the wiring as described in the section on The display unit freezes. The display unit shows lots of background noise 1. The unit may be set to use the manual sensitivity adjustment, and the sensitivity may be set too high. See the information on Setup Instructions. 2. The transducer may be mounted incorrectly, or may be fouled. Check the mounting as described in Section 2. Clean the transducer as described earlier in this section. The depth setting flashes often Note: Normally, this indicates that the bottom has moved out of range. 1. The transducer may not be installed correctly, or the signal may not be reaching the display unit. Recheck the instructions in Mounting the Transducer in Section 2. Check the transducer cable for signs of damage. If the cable is damaged, the transducer and cable should be replaced as a unit. 2. The voltage reaching the unit may be low, and this may be affecting the transmitting power. Check for problems with the wiring as described in the section on The display unit freezes.
The speed or log readings are wrong 1. The paddle wheel on the transducer may be fouled. Clean the parts as described in the section on Cleaning Instructions. 2. Check the speed calibration. Use the item for Speed Cal on the System Setup Menu. See the instructions in Section 2.
Servicing a Thru-Hull Transducer
If your boat has a thru-hull transducer, you can service it without removing the boat from the water. The sensor(s) are mounted in a cylindrical plug in the center of the transducer assembly. If necessary, you can remove this plug by working from the inside of the boat. The transducer housing includes a check valve to minimize the water intrusion when removing the insert. A small amount of water will enter the boat. This is normal. Immediately after removing the speed insert, place the dummy insert in the transducer housing. Do not leave the transducer without the speed or dummy insert in place.
