900 SERIES™ INTRODUCTION

Your 900 Series™ Ultra Wide Screen Fishing System comes in the following configuration:

• Humminbird® 947c 3D Combo: Ultra Wide Screen Fishing System with

Chartplotter (Maps) and Dual Frequency 455 kHz and 83 kHz Transducer, GPS Receiver included.

HOW THE 900 SERIES™ WORKS

Sonar uses sound waves to determine the presence and location of underwater objects. The time measured between the transmission of the sound wave and the reception of any reflection can be used to determine distance from an object. Analysis of the reflected signal can also be used to determine location, size, or composition of underwater objects.

Humminbird® products consist of two main components: the sonar unit and the transducer. The sonar unit contains the transmitter and receiver, as well as the user controls and LCD display. The transducer is mounted beneath the water surface and converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives reflected sound waves and converts them back into electrical signals for display on the sonar unit.

The transmit and receive cycle is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can "outrun" this sonar signal.

A number of variables affect the nature of information which can be derived from the sonar return. Sonar signals generated at a higher frequency have the advantage of greatly increased sonar resolution, although the distance (depth) a high-frequency signal can travel is relatively short. A low frequency signal can travel great distances, but provides poor sonar resolution. The shape of the transmitted sonar signal greatly

affects the information available as well. A single wide beam has a large area of coverage but poor resolution of detail. A narrow beam has excellent detail, but only a limited area of coverage.

3D SONAR

Your 900 Series™ Fishing System uses a six-element transducer that transmits at 455 kHz and is capable of reaching depths of 240 ft (75 m). Each transmitted beam is 16 degrees in width and is symmetrical. The six beams are lined up next to each other to provide a total coverage of 53 degrees from side to side, and 16 degrees from front to back. Using multiple narrow beams together gives you a wide area of coverage for terrain interpretation and fish location, without sacrificing the detail only a narrow beam can provide. Your 900 Series™ Fishing System gathers information from a continuous series of these returned signals. It then interprets this information to create a detailed 3-dimensional view of the terrain passing beneath your boat as you travel across the water.

2D SONAR

Your 900 Series™ Fishing System also has the capability of displaying traditional 2-dimensional sonar information from either a 455 kHz beam or an 83 kHz beam. The 455 kHz single beam has the advantage of providing increased sonar resolution but is limited to a depth capability of 240 ft (75 m). The 83 kHz single beam sonar has the advantage of providing sonar information to 1000 ft (330 m) but the sonar resolution is not as great as with the 455 kHz single beam.

531374-1_A - 947 Man.qxd 2/15/2005 7:52 PM Page 6

GPS AND CARTOGRAPHY

Your 900 Series™ uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information. The Global Positioning System (GPS) is a satellite navigation system designed and maintained by the U.S. Department of Defense. GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 10 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 10 meters of your actual position. The GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.

GPS uses a constellation of satellites that continually send radio signals to the earth. Your present position is determined by receiving signals from up to 12 satellites and measuring the distance from the satellites. The GPS Receiver, when attached to your 900 Series™, allows you to combine easy-to-use FishingGPS™ chartplotter and navigation capabilities with advanced fishfinding. The following GPS functionality is currently supported by the 900 Series™ when it is connected to a GPS Receiver:

• View current position

• View current track (breadcrumb trail)

• View precision speed and heading from your GPS receiver

• Save tracks, waypoints and routes

• Travel a route and navigate from one waypoint to the next.

NOTE: 900 Series™ supports Navionics® Gold Charts marine cartography and Navionics® HotMaps™ 2004 Gold for inland fishing. The 900 Series™ does not support Navionics® Classic Charts.

Your 900 Series™ also comes with a built-in World map with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models).

Your 900 Series™ uses the GPS Receiver to determine the position of the boat automatically, and uses the zoom level settings on a particular view to select the best chart to display. See Viewing Cartography for more information.

MULTI-MEDIA CARD (MMC) AND SD SLOT

Your 900 Series™ supports cartography, and has two multimedia card (MMC)/SD slots. Optional-purchase MMC and/or SD cards can contain additional detailed maps. You can also export navigation data from your unit onto an MMC/SD card (see Navigation Main Menu: Export All Nav Data). If you insert an MMC or SD card that contains a more detailed chart for a particular location, your unit will retrieve that chart and display it automatically.

Use the MMC/SD cards to update the software version of your control head. To update the software in your control head, plug in the appropriate MMC/SD card that contains a software update file; the unit will recognize it, will tell you what software version your control head is currently running, and will ask you if you want to update the software in the unit to match that on the MMC/SD card. You can obtain software updates from the www.humminbird.com website.

Use the illustration to locate the position of the MMC and SD slot cover, remove the cover, and then insert an MMC and/or an SD card into one or both slots - either slot can accept either an MMC or an SD card. The label on both types of cards should face down and away from you so that you’re looking at the back of the card. Press down on the card until it clicks into place, then replace the slot cover and tighten the screw snugly - do NOT overtighten, as this will not improve water resistance, and may damage the cover.

NOTE: Accessories may require a separate purchase. You can visit our website at www.humminbird.com to order these accessories online or contact our Customer Resource

Center at 1-800-633-1468.

CONTROL HEAD INSTALLATION

You have two choices for mounting your 900 Series™ control head:

• Gimbal mounting, where you use a surface on the boat, such as the dash, to

mount the control head so that it can be tilted up or down, or

• In-dash mounting, where you cut a hole in the dash in order to allow the control

head to be recessed into the dash, and the control head cannot be moved after mounting.

GIMBAL MOUNTING THE CONTROL HEAD

If you are gimbal mounting the Humminbird® 900 Series™, you can pre-assemble the unit in order to plan the best mounting location.

Parts and tools specific to gimbal mounting are:

• Gimbal mounting bracket and screws

• Gimbal mounting knobs and washers

• Phillips head screwdriver

• 5/16" socket wrench or flat head screw driver

• Hand drill with various drill bits

• Marine-grade silicone sealant.

1. Place the control head into the gimbal bracket. Make sure that the straight side of the gimbal arm is against the back side of the control head.

2. Place a 1" (25 mm) diameter black washer on the gimbal knob and then thread the knob and washer into the housing. Tighten the gimbal knob to secure the 900 Series™ control head to the mount. Repeat step 2 for the other side.

You can now place the control head in various locations to decide which is best for mounting. Rotating the mounting bracket to the top of the control head will allow for overhead mounting. The chosen mounting area should allow for sufficient room so the control head can pivot through the full tilt range and allow for easy removal and installation.

NOTE: You can drill the cable pass hole underneath the gimbal bracket, allowing you to thread the cables through the knock- out holes in the mount; however, if you cannot drill the hole directly under the mounting bracket, then you will need to drill the cable pass hole behind the bracket, and will need to mount the hole cover there instead.

NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. Fill all holes with marine grade silicone sealant.

NOTE: You must have underside access to the mounting location to pass the cables through to the surface. Also make sure that the mounting surface is adequately supported to protect the control head from excessive wave shock and vibration and provide visibility while in operation.

3. After the mounting location has been determined, loosen the gimbal knobs and remove the control head from the gimbal bracket.

NOTE: Alternate hole patterns are available underneath the gimbal mounting bracket, and may match existing holes on the boat. If you choose to use one of these alternate hole patterns, simply drill it out and use it to mount the bracket instead.

4. Place the gimbal bracket in the chosen position on the mounting surface and mark the four mounting screw locations using a pencil or center punch.

NOTE: Go to the installation instructions applicable to your transducer, GPS Receiver and accessories. Make the required installations and then run the cables to your control head mounting location. Do not cut any cabling (except the power cable). If your cables are too short, extensions are available from your local dealer or online from www.humminbird.com.

5. Set the gimbal bracket aside and drill the four mounting screw holes using a 5/32" (4.0 mm) drill bit.

6a. If the cables must pass through a hole directly beneath the mounting bracket,

mark and drill an additional 1" (25 mm) hole centered between the four mounting holes. Route the cables through the grommet, then press the grommet in place around the cables and into the 1" (25 mm) hole. Pass the cables out of the back of the mounting bracket. Using needle-nose pliers, break out the tabs on the rear of the mounting base. You will need to break out the cable tabs for the number of cables you want to run to your control head.

6b. If the cables cannot be routed directly beneath the mounting bracket, mark and

drill a 1" (25 mm) hole that will allow you to run the cables close to the bracket. Pass the cables through the 1" (25 mm) hole, routing the cables through the grommet and pressing the grommet into place. Place the hole cover over the mounting surface hole, then use it to mark the position of the two mounting screws. Remove the hole cover, drill the two mounting holes using a 9/64" (3.5 mm) bit, fill them with marine-grade silicone, then replace the hole cover and insert the #8 Phillips countersink wood screws. Hand-tighten only.

7. Place the mounting bracket on the mounting surface aligned with the drilled holes and fill the mounting holes with marine grade silicone. Insert the four #10 Slotted-Hex wood screws into the mounting holes. Hand-tighten only.

NOTE: Be sure that the cables pass through the slots on the hole cover or gimbal bracket break out tabs and there is enough cable slack to allow for the control head to pivot through its full tilt range. Extra cable slack will also help when connecting/disconnecting the cables.

8. Insert cable connectors into the proper recesses on the cable collector insert. The cable connectors are keyed to prevent reverse installation, so be careful not to force the connectors into the wrong slots. If you don’t have a cable for every hole in the insert, install the blank plugs to protect the control head from the weather.

9. While holding cables in place in the cable collector insert, thread the cables through the slot in the bottom of the cable collector cover, line up the cable collector insert and cover, then slide the cover into place on the insert.

NOTE: Tab on cable collector insert goes into slot on cover.

10. Attach the cable collector insert to the cable collector cover using the 2 Phillip screws provided.

11. Place the control head back onto the mounting bracket. Plug in the cable collector assembly to the back of the control head. Cable connectors and cable sockets are keyed to prevent reverse installation, so be careful not to force the connectors into the wrong sockets. Once the cable collector and all cables are plugged into the back of the control head, lock the assembly into place by threading the knurled screw into the threaded insert on the back of the housing. Adjust the control head to the desired viewing angle and secure by tightening the gimbal knobs.

NOTE: You may wish to dress the cabling with nylon wire ties in order to hold the cables together and create a cleaner assembly.

The Humminbird® 900 Series™ control head is now ready for operation.

IN-DASH MOUNTING THE CONTROL HEAD

If you are in-dash mounting the control head, start by placing the components on the surfaces where you intend to install them before installation. Make sure that the surfaces you have chosen provide adequate protection from wave shock, and that all cables can reach the control head.

NOTE: If a cable is too short for your application, extension cables are available. Call Humminbird® Customer Resource Center at 1-800-633-1468 for more information.

Parts and tools specific to In-dash mounting are:

• In-dash mount bracket and threaded rods

• In-dash mounting foam pads

• In-dash mounting template

• Reciprocating saw for cutting dash material

• Masking tape to hold mounting template in place.

1. Locate a suitable, flat area of the dash to mount the control head. The control head requires a depth of at least 3 1/2 inches.

2. Tape the provided In-Dash paper template to the desired in-dash mounting location.

3. At a location inside the dotted line on the template, drill a hole large enough to insert blade of reciprocating saw. Carefully begin cutting toward the dotted line, then follow the dotted line around the template. Remove the template when finished.

4. Insert and tighten the two threaded rods into the two threaded inserts located on the back side of the control head. Peel off the adhesive-backed foam pads and place them on the back of the control head; make sure you notice the difference between the longer top/bottom and shorter side pads.

5. Insert the control head through the mounting hole from the front side of the dash. From the back side of the dash, align the two threaded rods on the rear of the housing with the two holes on the in-dash mounting bracket. Place a washer onto each threaded rod, then secure bracket by placing a wing nut onto each threaded rod and tighten fully.

6. Insert cable connectors into the proper recesses on the cable collector insert. The cable connectors are keyed to prevent reverse installation, so be careful not to force the connectors into the wrong slots. If you don’t have a cable for every hole in the insert, install the blank plugs to protect the unit from the weather.

7. While holding cables in place in the cable collector insert, thread the cables through the slot in the bottom of the cable collector cover, line up the cable collector insert and cover, then slide the cover into place on the insert.

NOTE: Tab on cable collector insert goes into slot on cover.

8. Attach the cable collector insert to the cable collector cover using the 2 Phillip screws provided.

9. Plug the cable collector assembly into the back of the control head. Cable connectors and cable sockets are keyed to prevent reverse installation, so be careful not to force the connectors into the wrong sockets. Once the cable collector and all cables are plugged into the back of the control head, lock the assembly into place by threading the knurled screw into the threaded insert on the back of the housing. (Cable ties are provided to help you secure the cables in place by threading them through the available holes on the in-dash bracket).

NOTE: It is very important that the cable collector is used and secured in place in the In-Dash installation.

CONNECTING THE CONTROL HEAD POWER CABLE TO THE BOAT

A 6' (2 m) long power cable is included to supply power to the control head. You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire.

CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head MUST be connected to a 12 VDC power supply.

The control head power cable can be connected to the electrical system of the boat at one of two places: a fuse panel usually located near the console, or directly to the battery.

NOTE: Make sure that the power cable is disconnected from the control head at the beginning of this procedure.

1a. If a fuse terminal is available, use crimp-on type electrical connectors (not

included) that match the terminal on the fuse panel. Attach the black wire to ground (-), and the red wire to positive (+) 12 VDC power.

1b. If you need to wire the control head directly to a battery, obtain and install an

inline fuse holder and a 2.5 to 3 Amp fuse (not included) for the protection of the unit. Humminbird® is not responsible for over-voltage or over-current failures.

NOTE: In order to minimize the potential for interference with other marine electronics, a separate power source (such as a second battery) may be necessary.

You are now ready to install the transducer. Find the section that refers to your specific transducer installation method.

TRANSDUCER INSTALLATION

There are three different installation methods for your transducer:

• Transom Transducer

• Inside the Hull Transducer

• Trolling Motor Transducer.

Find the section that describes the method of installation you will be using.

NOTE: If the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often at very little or no charge, depending on the transducer. Call the Humminbird® Customer Resource Center (1-800-633-1468) for details and pricing, or visit

www.humminbird.com, Product Support/Transducer Exchange for more information.

NOTE: Due to the wide variety of hulls, only general instructions are presented in this

installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. In addition to the parts supplied, you will need a hand drill with various bits, a socket wrench (5/16"), a Phillips head screwdriver, and marine-grade silicone sealant.

WARNING: Do not touch an active transducer during operation, as this may cause physical discomfort and may result in personal injury in the form of tissue damage. Handle the transducer only when the power to the control head is off.

TRANSOM TRANSDUCER INSTALLATION

If you will be installing a transom mounted transducer, use the procedures in this section. There are several procedures you will have to perform in order to install a transom-mounted transducer. They are:

• Determine transducer mounting location

• Mount the bracket to the boat

• Attach the pivot to the transducer

• Mount the transducer pivot assembly to the bracket

• Adjust the running position of the transducer

• Route the transducer cable

• Perform a final test of the transom transducer installation.

To determine transducer mounting location:

NOTE: If transom mounting is not possible because of a stepped hull or cavitation noise, and you have a single layer fiberglass hull, In-hull installation is an option. See Inside the Hull Transducer Installation for more information.

1. First, determine the best location on the transom to install the transducer. Consider the following to find the best location:

• It is very important to locate the transducer in an area which is relatively free of turbulent water. As a boat moves through the water, turbulence is generated by the weight of the boat, and the thrust of the propeller(s) - either clockwise or counter- clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or inboard/outboard boats, it is best to locate the transducer at least 15" (380 mm) to the side of the propeller(s).

• The best way to locate turbulence-free water is to view the transom while the boat is moving. This method is recommended if maximum high-speed operation is a high priority. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs.

• The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment.

• On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal.

• If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered (see Inside the Hull Transducer Installation).

To mount the transducer bracket to the boat:

1. Remove the transducer mounting template from this manual. (See Appendix A, Transducer Mounting Template: SHS 7W).

2. Hold the template on the transom of the boat in the location where the transducer will be installed. Align the template vertically, matching the lower edge of the transom with the bottom corner of the template. If your propeller moves clockwise as the boat moves forward, mount the transducer on the starboard side, and use the bottom left corner of the template. If your propeller moves counterclockwise as the boat moves forward, mount the transducer on the port side, and use the bottom right corner of the template.

3. Using a pencil or punch, mark the three mounting holes on the transom. Do not mark or drill any other holes at this time.

4. Using a 5/32" (4.0 mm) bit, drill the three holes to a depth of approximately 1" (25 mm). On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. Use a marine-grade silicone sealant to fill the drilled holes.

5. Align the metal mounting bracket with the mounting holes. The center slot should be above the two outer slots. (This bracket and all other hardware supplied is top quality stainless steel for maximum strength and corrosion protection.) Insert the three 1" (25 mm) flat head wood screws into the drilled holes, but do not completely tighten.

To attach the pivot to the transducer:

1. Attach the pivot to the transducer body, using the two 1/4"-20 x 5/8" (16 mm) machine screws, toothed washers, and square nuts. The toothed washers must fit on the inside of the transducer ears, between the pivot and the ears. The square nuts will be prevented from rotating by the pocket in the back of the pivot. An Allen wrench is provided which fits all the 1/4"-20 screws, but do not fully tighten the screws at this time.

To mount the transducer pivot assembly to the bracket:

1. Slide the assembled transducer into the metal bracket from the bottom, aligning the large hole at the top of the bracket with the hole in the pivot.

2. Insert the headed pin through the pivot holes in the bracket and pivot. The headed pin can be inserted from either side of the bracket.

3. Place the nylon washer over the opposite end of the headed pin. Place the stainless washer over the ¹⁄₄"-20 x ⁵⁄₈" screw threads, then insert into the opposite end of the headed pin and finger tighten only. The screw has a thread locking compound on the threads to prevent loosening, and should not be fully tightened until all adjustments are made.

NOTE: The running position of the transducer is now completely adjustable. Subsequent adjustment may be necessary to tweak the installation after high speed testing.

To adjust the running position of the transducer:

The transducer mounting bracket allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation. Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the installation after high-speed testing.

NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in exactly the same way.

1. First, adjust the pivot angle of the transducer body, so it is parallel with the length of the hull of the boat.

2. Fully tighten the two pivot screws, using the supplied Allen wrench. Access to the pivot screws is provided by the lower holes in the side of the mounting bracket. It may be necessary to re-tighten the pivot bolt after initial use as the plastic may still be conforming to the pressure from the lock washers.

3. Adjust the height of the assembly so the face of the transducer is 1/8" (3 mm) to 1/4" (6 mm) beneath the bottom of the transom, and fully tighten the three mounting screws.

4. In order to gain access to the mounting screws, the transducer assembly must be pivoted up in the bracket as shown. Be careful not to alter the running angle as some force is necessary to pivot the assembly.

5. If access to the top mounting hole is not possible due to the selected height of the transducer, fully tighten the two lower screws, then simply remove the headed pivot pin and the transducer assembly, and tighten the top screw, then reassemble.

6. Confirm that the pivot angle has not changed and that all mounting screws are fully tightened.

To route the transom transducer cable:

The transducer cable has a low profile connector that must be routed to the point where the control head is mounted. There are several ways to route the transducer cable to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat.

NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.

1. Unplug the other end of the transducer cable from the control head. Make sure that the cable is long enough to accommodate the planned route by running the cable over the transom.

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50' (15 m). For assistance, contact the Customer Resource Center at www.humminbird.com or call 1-800- 633-1468 for more information.

NOTE: Since the transducer may need to pivot up to 90 degrees in the bracket if it strikes an object, make sure there is sufficient cable slack to accommodate this motion. It is best to route the cable to the side of the transducer so the cable will not be damaged by the rotation of the transducer.

2. If you will be routing the cable through a hole in the transom, drill a 5/8" diameter (16 mm) hole above the waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and proceed to the next step immediately.

3. Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64" (3.6 mm) holes, then fill both holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8" (16 mm) wood screws.

4. Route and secure the cable by attaching the cable clamp to the transom; drill one 9/64" dia. (3.5 mm) x 5/8" deep (16 mm) hole, then fill hole with marinegrade silicone sealant, then attach the cable clamp using a #8 x 5/8" (16 mm) screw.

5. Plug the other end of the transducer cable back into the control head connection holder.

To perform a final test of the transom transducer installation:

After transom transducer installation, please perform the final testing and then finalize the installation (see Test and Finish the Transducer Installation).

INSIDE THE HULL TRANSDUCER INSTALLATION

If you choose to mount your transducer inside the hull of your boat, perform the procedures in this section. In-hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird® cannot guarantee depth performance when transmitting and receiving through the hull of the boat, since some signal loss occurs. The amount of loss depends on hull construction and thickness, as well as the installation position and process.

This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, thus reducing signal strength.

NOTE: In-hull mounting requires an installed and operational control head.

Determine the transducer mounting location:

Decide where to install the transducer on the inside of the hull. Consider the following to find the best location:

• Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes and other protrusions, as these create turbulence.

• As a general rule, the faster the boat can travel, the further aft and closer to the centerline of the hull the transducer has to be located in order to remain in contact with the water at high speeds.

Trial installation:

You will not be able to adjust the mounting after an inside the hull transducer is installed. It is best, therefore, to perform a trial installation first that includes running the boat at various speeds, in order to determine the best mounting area before permanently mounting the transducer.

1. Plug the transducer into the control head, then power up the control head. When the control head detects a functioning transducer, it will automatically enter Normal operating mode.

2. View the sonar signal at its best by holding the transducer over the side, immersed in the water, so that it is pointing straight down over a known flat bottom. Use the display to benchmark against the sonar signal that will be detected once the transducer is placed in the hull.

3. Place the transducer body face down at the identified mounting location inside the hull, with the end that has the mounting ears pointed towards the bow of the boat.

Step

Preferred Mounting Area

4. Fill the hull with enough water to submerge the transducer body. Use a sand-filled bag or other heavy object to hold the transducer in position. The transducer cannot transmit through air, and the water purges any air from between the transducer and the hull, and fills any voids in the coarse fiberglass surface.

5. View the sonar signal on the display and compare against what you observed in Step 2, making sure that the boat is in the same location as it was during your observations in Step 2. If the results are comparable, move on to Step 6. Otherwise, locate a new position in the hull and repeat Steps 3 through 5.

6. Run the boat at various speeds and water depths while observing the screen on the control head. If depth performance is required, test the transducer in water at the desired depth. If the performance is acceptable, move on to Step 7. If the performance is not acceptable, repeat Steps 3 through 6.

7. Once you have determined the best mounting location using the above steps, mark the position of the transducer.

Route the cable:

1. Once the mounting location is determined and you have marked the position of the transducer, route the cable from the transducer to the control head.

Permanently mount the transducer:

1. Make sure the position of the transducer is marked.

2. Remove the water from inside the hull and thoroughly dry the mounting surface. If the surface is excessively rough, it may be necessary to sand the area to create a smooth mounting surface.

3. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy. Avoid trapping air bubbles.

4. Coat the face of the transducer and the inside of the hull with epoxy.

5. Press the transducer into place with a slight twisting motion to purge any trapped air from underneath, keeping the end of the transducer that has the mounting ears pointed forward, towards the bow of the boat.

NOTE: Proper operation requires the end of the transducer that has the mounting ears to face towards the bow of the boat.

6. Weight the transducer so that it will not move while the epoxy is curing.

NOTE: When the epoxy cures, no water is necessary inside the hull.

7. If you unplugged the transducer cable at the beginning of this procedure, plug it back into the control head.

NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.

TROLLING MOTOR TRANSDUCER INSTALLATION

If you want to install the transducer on a trolling motor, use this procedure. Several styles of the transducer are compatible with trolling motor mounting. If you have a trolling motor bracket, refer to the separate installation instructions that are included with the bracket.

NOTE: After trolling motor transducer installation, please perform the final testing and then finalize the installation (see Test and Finish the Transducer Installation).

If you don’t have a trolling motor transducer, there are several options:

• You may purchase a Trolling Motor Adapter kit that will allow you to mount the transducer on the trolling motor.

• You may also exchange your NEW and UNASSEMBLED transducer (with mounting hardware included) for a trolling motor transducer.

There are also several transducer switches available that support the following configurations:

• Two control heads with one transducer

• Two transducers with one control head.

NOTE: Call the Humminbird® Customer Resource Center (1-800-633-1468) for details and pricing, or visit www.humminbird.com for more information.

TEST AND FINISH THE TRANSDUCER INSTALLATION

When you have installed both the control head, the transom transducer, and accessories and have routed all the cables, you must perform a final test before locking the transducer in place. Testing should be performed with the boat in the water, although you can initially confirm basic operation with the boat out of the water.

NOTE: If you have installed an in-hull mount transducer, this procedure does not apply, as the transducer is already locked in place.

1. Press POWER once to turn the control head on. There will be an audible chirp when the button is pressed correctly. If the unit does not power-up, make sure that the connector holder is fully seated and that power is available.

2. If all connections are correct and power is available, the control head will enter Normal operation. If no transducer is detected (or one is not connected), the unit will go into Simulator mode and will indicate this by displaying the word Simulator on the control head display.

NOTE: The transducer must be submerged in water for reliable transducer detection.

3. If the bottom is visible on-screen with a digital depth readout, the unit is working properly. Make sure that the boat is in water greater than 2 ft (.6 m) but less than the depth capability of the unit, and that the transducer is fully submerged, since the sonar signal cannot pass through air.

4. If the unit is working properly, gradually increase the boat speed to test highspeed performance. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. Angling the rear of the transducer downward and/or lowering the transducer farther into the water will help achieve depth readings at high speeds.

531374-1_A - 947 Man.qxd 2/15/2005 7:53 PM Page 22

NOTE: Due to the wide variety of boat hulls, it is not always possible to obtain high speed depth readings.

NOTE: It is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved.

Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings.

5. Mark the transducer bracket location on the transom with a pencil, then pop up the bracket to reveal the mounting screws. Tighten the stainless steel mounting bracket screws to secure in place.

Hand-tighten only!

GPS RECEIVER INSTALLATION

To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky. The effective area of reception is 10° above the horizon. Different circumstances determine the mounting method appropriate for your GPS receiver.

If you have… Then use:

STEM MOUNTING WITH AN EXISTING 1" - 14 THREAD STEM

Follow these steps to stem mount the GPS receiver:

NOTE: If you have an existing stem for mounting the GPS receiver, proceed directly to step 2 of the following procedure.

1. Determine the best location to mount your GPS receiver. Preplan and test the cable routing to your control head before any drilling or cutting of your boat surfaces. If you have purchased hardware to stem mount your GPS receiver, follow the instructions included with that hardware to mount the stem (antenna pole).

NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

2. Screw on the receiver base to the stem first, making sure that the stem pipe does not protrude from the receiver base. This adds protection to the cable when pulling it through the pipe stem. In addition to this, de-burr the pipe edges to reduce cable abrasion.

3. Use electrical tape to secure the NMEA pigtail to the cable as shown.

NOTE: Leave the NMEA pigtail secured to the cable unless needed. This will make removing the receiver easier.

4. Route the GPS receiver cable through the stem and continue with the planned route you chose in step 1.

5. Attach the GPS receiver to its base using the included #6 - 7/8" screws.

ACCESS UNDER MOUNTING LOCATION

Follow these steps to deck mount the GPS receiver when routing the cable down through the mounting location:

1. Determine the best location, then test route the 20' (6 m) cable from the mounting location to the control head.

NOTE: Installation details may vary with unit configuration.

2. Mark the mounting location and drill a 3/4" (19 mm) hole for the cable and cable plug. Route the cable.

3. Cover the cable hole with the receiver. Make sure the receiver is flush on the surface and mark the two mounting holes with a pencil or punch.

4. Move the receiver to the side and drill two pilot holes using a 9/64" (3.5 mm) bit.

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

5. Align the GPS receiver screw holes over the pilot screw holes and attach with the #8 - 1 1/4" Phillips head screws. Hand tighten only!

NOTE: If the mounting surface is thin and made of a lighter material, a backing material may be needed below the mounting surface.

NO ACCESS UNDER MOUNTING LOCATION

Follow these steps to deck mount the GPS receiver in a situation where you must route the cable to the side because there is no space for a cable underneath the mounting location.

1. Determine the best location, then test route the cable from the mounting location to the control head.

NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).

2. Confirm the cable length is good and route the cable from the receiver to the control head. If holes are required to route the cable, they must be 3/4" (19 mm) to allow for the cable connector. Secure the NMEA pigtail with electrical tape.

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

3. The GPS receiver has two wire routing notches. Use the cable notch closest to the intended cable route.

4. With the cable routed, position the GPS receiver in the planned mounting location and mark the mounting holes with a pencil or punch.

5. Move the GPS receiver to the side and drill the two 9/64" (3.5 mm) pilot holes.

6. Align the GPS receiver's screw holes over the pilot screw holes and attach with the #8 - 1 1/4" Phillips head screws. Hand tighten only!

FINISH ROUTING THE CABLE AND CHECK GPS RECEIVER OPERATION

After installing a GPS receiver, you should perform the following procedure to finish routing the GPS cable to the control head and to check to make sure that the control head is working correctly.

1. Secure the cable along its path to the control head as needed with cable ties.

2. Plug in the GPS receiver cable into the Communications port on the control

head. See Testing the System Installation to use the System Status start-up option and/or the GPS Diagnostic View to confirm a good installation.

TEMPERATURE PROBE ACCESSORY INSTALLATION

The Temperature Probe incorporates a temperature sensitive probe in a highimpact plastic housing. The module is intended for installation on the transom, and will work well on almost any boat.

In addition to the parts supplied, you will need a hand drill with various bits, marine-grade silicone sealant, and a Phillips head screwdriver.

Install the temperature probe accessory:

1. Locate an area on the transom of your boat that will be 6” to 8” or farther from the transducer(s). This area must also maintain contact with the water, even at high speeds. Do not mount the sensor directly in front of the propeller or outdrive, and make sure that there are no protrusions such as ribs, rows of rivets, or transducers directly forward of the mounting location, as these may affect the flow of water over the temperature probe.

2. Align the sensor in the clamp, and align it on the transom so that the lower edge is flush with the hull of the boat, and mark the hole location.

3. On fiberglass hulls, it is best to start with a smaller drill bit and use progressively larger bits to reduce the chance of chipping or flaking the outer coating. Drill a 1/8” (3 mm) mounting hole approximately 3/4” (19 mm) deep.

4. Seal the mounting holes with marine-grade silicone sealant, and attach the sensor to the transom using the screw provided. Hand tighten only!

Routing the cable to the control head:

1. You may route the cable over the top of the transom, or drill a 5/8” (16 mm) diameter hole in the transom directly above the sensor and above the waterline to route cable through. Use the cable clamps provided to secure the cable to the transom of the boat. If you use a through-hole, then also use the included escutcheon plate to dress the hole.

NOTE: On fiberglass hulls, it is best to start with a smaller drill bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.

2. All mounting screws not specified require a 9/64” (3.5 mm) pilot hole drilled approximately 5/8” (16 mm) deep. Additionally, seal any hole drilled in the transom of the boat with marine-grade silicone sealant (not included).

3. Route the cable to the Control Head, and insert the connector into the appropriate slot. Use the connector designated for accessories on the control head.

4. If the connections are correct, the Control Head will begin displaying water temperature information immediately (assuming that the control head is powered on). If the gauge fails to read properly at high speeds, adjust the height of the sensor on the transom.

TESTING THE SYSTEM INSTALLATION

After you have completed the installation of the control head, transducer, and any other accessories such as the GPS receiver, and have made all the cabling connections required, you must test the installation before using the system. Thorough testing should be performed with the boat in the water; however, you can confirm basic operation initially with the boat out of the water as well.

To test the installation:

1. Press the POWER/LIGHT key on the control head once to turn on the control head. (There will be an audible chirp to let you know that you pressed the key, and the initial Title screen will appear.) If the unit does not power up, make sure that power is available. While the Title screen is shown on the display, press the MENU key to display the Start-Up Options menu. Use the UP or DOWN 4-WAY Cursor keys to position the cursor, then the RIGHT Cursor key to select System Status from the Start-Up Options menu (see the Start-Up Options Menu section for more information about these menu choices). The System Status Self Test screen will appear.

NOTE: If you wait too long, the system will default to whichever menu mode happens to be highlighted, and you will have to start again.

2. Self Test displays results from the internal diagnostic self test, including unit serial number, Printed Circuit Board (PCB) serial number, software revision, total hours of operation and the input voltage. See System Status for more information about the Self Test.

3. From the System Status screen, view accessory connections by pressing the VIEW key. See System Status for more information about the Accessory Test.

4. From the System Status screen, see a GPS Diagnostic View by pressing the View key. GPS Diagnostic View shows a sky chart and numerical data from the GPS receiver. The sky chart shows the location of each visible GPS satellite with its satellite number and a signal strength bar. A dark grey bar indicates that the satellite is being used to determine your current position. A light gray bar indicates that the satellite is being monitored, but is not yet being used.
