HOW SONAR WORKS

Sonar technology is based on sound waves. The HDR 610 Digital Depth Gauge uses sonar to determine depth directly below the transducer. Your HDR 610 Digital Depth Gauge consists of two components: the HDR 610 sonar unit and the transducer. The sonar unit contains the transmitter and receiver, as well as the user controls and 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 the reflected sound waves and converts them back into electrical signals for display on the sonar unit.

Sonar 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.

INSTALLATION OVERVIEW
Before you start installation, we encourage you to read these instructions carefully in order to get the full benefit from your HDR 610 Digital Depth Gauge. You will install your HDR 610 depthsounder first, then your transducer. When you are done with both of these installation tasks, you should perform a final installation test before operating your HDR 610. Please make sure that the following parts are included for your depthsounder: HDR 610 depthsounder "U" bracket and mounting hardware 2 cable ties. Also, please make sure the following parts are included for your transducer: Transom mount or Puck transducer with 20' of cable Transducer mounting hardware kit. In addition to the hardware supplied, you will need the following for installation and operation: Powered hand drill and various drill bits, including a 2 1/8" hole saw, if your boat does not have an existing gauge hole Phillips-head and flat-head screwdrivers Ruler or measuring tape Pen or pencil 12 Volt power source (your boat's battery) Marine-grade silicone sealant (for sealing drilled holes) Two-part, slow-cure epoxy (for inside-the-hull transducer installation only).
NOTE: If you are wiring directly to the boat's battery, you will also need a 1 Amp fuse and a fuse holder.

INSTALLING THE HDR 610

Before installing the HDR 610, make sure you have the following parts: HDR 610 depthsounder "U" bracket and mounting hardware 2 cable ties. Perform the following high-level steps by following the instructions in each numbered section to install the HDR 610 depthsounder: 1. Locating the HRD 610 mounting position 2. Cutting the mounting hole 3. Customizing and assembling the HDR 610 4. Installing the HDR 610 5. Installing the buzzer 6. Connecting the transducer cable 7. Connecting to the power supply.

Page 8

1. Locating the HDR 610 Mounting Position
You must select an appropriate mounting location for the HDR 610. Consider different positions on the console or deck of the boat. Remember that the cables for the transducer and power must reach the mounting location. Extension cables are available. The mounting surface should be visible to the boat operator and adequately supported to protect the HDR 610 from excessive wave shock and vibration. Allow at least 2" clearance at the back, sides, and top of the unit for connection, air flow, and ease of installation and removal.

2. Carefully line up the notch on the bottom of the overlay with the tab at the bottom of the face of the HDR 610, then press the overlay into place so that all buttons and the display show through. 3. The bezel is keyed to fit only one way onto the front of the HDR 610. There are two opposing sets of tabs on the inside of the bezel: two wide tabs, and two tabs with slots in them. Find the tab that has the asymmetrical slots (refer to the illustration) and push the bezel onto the front of the HDR 610 according to the illustration.

2. Cutting the Mounting Hole
Once you have selected your mounting location, perform the following steps: 1. Mark the desired mounting location, then drill a pilot hole. 2. Drill a 2 1/8" diameter hole using a hole saw and hand drill. This is a standard hole saw readily available for rental or purchase. If you prefer, any marine service shop can perform this task.
3. Customizing and Assembling the HDR 610
Your HDR 610 comes with both black and white bezels, and both black and white overlays. You must select one color for the bezel, and another color for the overlay, and perform the following assembly steps: 1. Peel off the protective backing from the overlay, being careful not to let the adhesive touch anything prematurely.
WARNING: In order to provide a lasting, waterproof bond, the overlay adhesive is extremely sticky, and therefore you will NOT be able to re-position it once you have stuck it onto the face of the HDR 610.

4. Installing the HDR 610
Once you have your mounting hole cut, perform the following steps: 1. Insert the HDR 610 from the front of the panel. 2. Install the "U" bracket and wingnut from the rear of the panel, and make sure that the face of the HDR 610 is oriented correctly, so that the top of the unit is at the top of the hole.
6. Connecting the Transducer Cable
Connect the transducer cable to the transducer connector on the HDR 610.
NOTE: The connector is keyed to prevent reverse installation, so be careful not to force the plug into the connector the wrong way.
7. Connecting to the Power Supply
Use the following information to connect your HDR 610 to an appropriate power supply: If your boat has an electrical system, there is probably a fuse panel in the console area that can be used to attach the HDR 610 power cable. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on the fuse panel, and attach the black wire to ground, and the red wire to 12 VDC power. You must use a 1-Amp fuse in the connection. 36" of power cable is included; you may shorten or lengthen this cable using 18-gauge, multi-strand copper wire.

Inline Fuse Holder NOTE: If the panel into which you are mounting the unit is greater than 1/4" thick, the "U" bracket may appear too long. You may modify the "U" bracket by using pliers to break the legs of the bracket at the score lines. Shorten the bracket in gradual stages to avoid making it too short. CAUTION: Some boats have 24 or 36 Volt electrical systems. Make sure that your HDR 610 is connected to a 12 VDC power supply. Use a voltage conditioner for variable inputs.
3. Tighten the wingnut to secure the installation.
If you must wire the HDR 610 directly to a battery, make sure that you install an in-line fuse holder and a 1-Amp fuse (not included) for the protection of the unit. Humminbird is not responsible for over-voltage or over-current failures.

5. Installing the Buzzer

Once the unit is mounted in the dash, secure the buzzer either to the metal bracket or to a nearby wire bundle using the cable ties included.

TRANSDUCER INSTALLATION
If you have a transom mount transducer you can mount it on the transom (preferred), in the hull, or you can purchase the trolling motor adapter and mount it on your trolling motor. If you have a puck transducer then you can ONLY mount it in the hull; there is a separate inside the hull mounting section for puck transducers. Find the correct section for your transducer installation type. The included transducer is designed for transom mounting on the boat (directly exposed to the water). On fiberglass hull boats, this same transducer can be bonded to the inside of the hull. When mounted inside the hull, the sonar signal actually passes through the hull of the boat. One of these two mounting techniques will produce acceptable results on most boats. There are, however, several situations that may demand a different type of transducer. Inboard boats, wood or metal hulls, and sailboats often have unique transducer mounting requirements.
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 depthsounder 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).

2. Mounting the Bracket

1. Remove the transducer mounting template from the end of this manual.
NOTE: Please make sure that you use the correct drill holes for the hull composition of your boat.
TRANSOM TRANSDUCER INSTALLATION
1. Locating the Transducer Mounting Position
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.
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.
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 counter-clockwise 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 two mounting holes (shown on the template for your type of hull) on the transom. Do not mark or drill any other holes at this time. 4. Using a 9/64" (3.5 mm) bit, drill the two holes to a depth of approximately 1" (25 mm).

Use 5/32" drill bit

3. Transducer Assembly

NOTE: The transducer assembly referred to in this step consists of the transducer connected to either the Single Piece or the Two Nyloc Piece Kick-up mounting bracket. Nut
Kick-up Pivot Knuckle Transducer Arms Pivot Bolt
1. Attach the Single Piece mounting bracket or the Two Piece Kick-up pivot to the transducer body, using the 1/4 - 20 x 1 1/4" Phillips head pivot bolt, the nyloc nut, and the two toothed lock washers.
NOTE: The toothed lock washers must be positioned between the transducer arms and the pivot knuckle regardless of mounting bracket type.

Page 14

2. Using a Phillips screwdriver and a 7/16" wrench, loosely tighten the pivot bolt. Do not completely tighten the assembly at this time, so the pivot angle can be adjusted later. 3. Only if you have a Kick-up transducer mounting assembly, insert the pivot/transducer assembly into the mounting bracket. 4. Do not snap the assembly closed.

Toothed Lock Washer

3. Before removing the template, adjust the height of the assembly so the face of the transducer touches the face of the template. Mark the position of the mounting bracket on the transom with a pencil. 4a. If you are using the Two Piece Kick-up mounting bracket, force the pivot to the Up position to gain access to the Normal cavitation mounting screws. Make sure that the transducer location has not changed, then hand tighten the two mounting screws. Snap the pivot back down. 4b. If you are using the Single Piece mounting bracket, make sure that the transducer location has not changed, then hand tighten the two mounting screws. 5. Confirm that the pivot angle has not changed.
4. Mounting the Transducer Assembly to the Transom
1. Apply marine-grade silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom. 3. Using the appropriate tool for your mounting hardware, attach the transducer assembly to the boat transom as shown , using #8 x 5/8" (16 mm) wood screws. Do not fully tighten the mounting screws in order to vertically adjust the transducer. If you have a Two Piece Kick-up transducer mounting assembly, snap the pivot down into place.

Page 16

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" dia. (3.5 mm) x 5/8" deep (16 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 marine-grade 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 depthsounder connection holder.
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.

7. Final Testing

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

2. 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 depthsounder, then power up the depthsounder. When the depthsounder 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 pointed end towards the bow. 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 fibergalss surface. 5. View the sonar signal on the display and compare against what was 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 depthsounder. 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.

6. Your depthsounder is now ready for operation. 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 depthsounder, then power up the depthsounder. When the depthsounder 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 Preferred Mounting Area 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.

Page 22

3. Place the transducer body face down on the inside of the hull in the area you have selected. 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.
3. Mix an ample quantity of two-part slow cure epoxy slowly and thoroughly. 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.
NOTE: Puck or round, circular-bottomed transducers have no directional bias, and therefore orientation of these types of transducers is not as important.

5. View the sonar signal on the display and compare against what was 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 depthsounder. 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.
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 provide a smooth mounting surface.

OPERATING THE HDR 610
Your HDR 610 Digital Depth Gauge sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object. As your HDR 610 transducer receives sonar signals, it converts them to a digital depth that is shown on the HDR 610 display. The depth reading is continuously updated as you travel across the water. The liquid crystal display (LCD) offers sharp viewing, even in bright, direct sunlight, and is continuously lit for nighttime operation.

Page 28

MAINTENANCE
To keep both your HDR 610 and your transducer working properly, perform the following maintenance tasks as needed.
3. To enable Keel Offset, press the SET key until the KO icon is displayed on the screen. 4. The available settings are +10 to -10 units. The default setting of the unit is Off, which is displayed as zero (0.0). From the default setting of 0.0, use the DOWN Arrow key to enter a negative (-) number (for depth measurements from the keel of the boat); use the UP Arrow key to enter a positive (+) number (for depth measurements from the waterline). 5. After your selection is made, wait 5 seconds for the unit to return to normal operation. The KO icon should now be visible.
EXAMPLE: The following figures depict a scenario where the Keel Offset has been set to -2 feet. The third figure shows the return to normal operation with the updated depth readout.

HDR 610 MAINTENANCE

If your HDR 610 unit comes into contact with salt spray, simply wipe the affected surfaces with a cloth dampened in fresh water. Do not use a chemical glass cleaner on the lens, as chemicals in the solution may cause cracking in the lens. When cleaning the LCD protective lens, use a chamois and non-abrasive, mild cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid scratching the lens.
WARNING: Never leave your HDR 610 in a closed car or trunk; the extremely high temperatures generated in hot weather can damage the electronics.

TRANSDUCER MAINTENANCE

If your boat remains in the water for long periods of time, algae and other marine growth can reduce the effectiveness of the transducer. Periodically clean the face of the transducer with hot water. Pivoting the transducer up in the bracket may allow better access for inspection or cleaning. If your boat remains out of the water for a long period of time, it may take some time to wet the transducer after it is returned to the water. Small air bubbles can cling to the surface of the transducer and interfere with proper operation. These bubbles will dissipate with time, or you may wipe the face of the transducer with your fingers after the transducer is in the water.

TROUBLESHOOTING

Before contacting the Humminbird Customer Resource Center, please read the following section. Taking the time to review these troubleshooting guidelines may allow you to solve a performance problem yourself, and therefore avoid sending your unit back for repair.
NOTE: Do not attempt to repair the HDR 610 yourself, as there are no user serviceable parts inside, and special tools and techniques are required for reassembly in order to maintain the waterproof integrity of the housing. Repairs should be performed only by authorized Humminbird technicians.

Page 30

HDR 610 Doesn't Power Up
If your HDR 610 doesn't power up, refer to the Installation section, and make sure that: the power cable is properly connected to the HDR 610; the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground; the fuse is operational; a fuse can often appear to be good when in fact it is not; check the fuse with a tester or replace it with a known good fuse; if the unit is wired through a fuse panel, make sure that the panel is powered, as accessory fuse panels are often controlled by a separate switch, or even the ignition switch of the boat; the battery voltage of the power connector is between 10 and 16 VDC. Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.

1-YEAR LIMITED WARRANTY

We warrant the original retail purchaser that products made by Humminbird have been manufactured free from defects in materials and workmanship. This warranty is effective for one year from the date of original retail purchase. Humminbird products found to be defective and covered by this warranty will be replaced or repaired free of charge at Humminbird option and returned to the customer freight prepaid. Humminbird sole responsibility under this warranty is limited to the repair or replacement of a product that has been deemed defective by Humminbird. Humminbird is not responsible for charges connected with the removal of such product or reinstallation of replaced or repaired parts. This warranty does not apply to a product that has been: Improperly installed; Used in an installation other than that recommended in the product installation and operation instructions; Damaged or has failed because of an accident or abnormal operation; Repaired or modified by entities other than Humminbird. Please retain your original receipt as a proof of the purchase date. This will be required for inwarranty service. THIS WARRANTY IS EXPRESSLY IN LIEU OF ANY OTHER WARRANTIES, OBLIGATIONS OR LIABILITIES ON THE PART OF HUMMINBIRD AND WILL BE THE CUSTOMER'S EXCLUSIVE REMEDY, EXCEPT FOR ANY APPLICABLE IMPLIED WARRANTIES UNDER STATE LAW WHICH ARE HEREBY LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF ORIGINAL PURCHASE. IN NO EVENT WILL HUMMINBIRD BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES FOR BREACH OF ANY EXPRESS OR IMPLIED WARRANTY RELATING TO THE PRODUCTS. Some states do not allow limitations on an implied warranty, or the exclusion of incidental or consequential damages, so the above exclusions may not apply to you. You may also have other rights, which vary from state to state.
No Bottom Reading on the Display

If there is no bottom reading visible on the display, there are a number of possible causes for this condition, including: if the loss of bottom information occurs only at high boat speeds, then a transducer adjustment may be needed (refer to the Transducer Installation section); check the transducer cable connection on the back of the HDR 610 and make sure that the cable to the transducer has not been cut or pinched, as even a small abrasion in the cable can affect performance significantly. Correct any known problems, including adjusting the transducer, or actually replacing the transducer cable if necessary.
No Continuous Depth Display in Very Shallow Water
Losing continuous depth when the boat is in very shallow water is normal, because the automatic range control cannot lock onto the bottom in depths of one foot or less.
HUMMINBIRD SERVICE POLICY
Even though you'll probably never need to take advantage of our incredible service policy, it's good to know that we back our products this confidently. We do it because you deserve the best. We will make every effort to repair your unit within three business days from the receipt of your unit at our factory. This does not include shipping time to and from our factory. Units received on Friday are typically shipped by the following Wednesday, units received Monday are typically shipped by Thursday, etc. All repair work is performed by factory-trained technicians to meet exacting factory specifications. Factory-serviced units go through the same rigorous testing and quality control inspections as new production units.
Screen Fades, Images Are Not Sharp
If the screen begins to fade, and images are not as sharp as normal, check the input voltage. The HDR 610 will not operate on input voltages below 10 VDC.
Bottom Reading Disappears During a Hard Turn
Losing the bottom reading temporarily when the boat is executing a hard turn is normal, as the transducer emerges from the water during such a turn; this condition should correct itself once the turn is completed.
