How Sonar Works
Sonar technology is based on sound waves. The HDR 650 Digital Depth Sounder
uses sonar to determine depth directly below the transducer. Your HDR 650
Digital Depth Sounder consists of two components: the HDR 650 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.

1. Locating the HDR 650 Mounting Position
You must select an appropriate mounting location for the HDR 650. Consider
different positions on the console or deck of the boat, and note the following:
• 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 650 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.
Choosing Mounting Hole Location
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 650
Your HDR 650 includes a variety of face plates and trim rings so that you can
customize the appearance.
1. Select one face plate and one trim ring.
2. Peel off the protective backing from the face plate. Be careful not to let the
adhesive touch anything prematurely.
CAUTION: In order to provide a lasting, waterproof bond, the face plate adhesive
is extremely sticky, and you will NOT be able to re-position it once you have stuck
it onto the face of the HDR 650.
3. Carefully line up the face plate with the face of the HDR 650. Press the face
plate into place so that all keys are accessible and the display is visible (see
illustration).
4. Align the inside tabs of the trim ring with the HDR 650 tabs, and snap the
trim ring onto the front of the HDR 650 (see illustration).

6. Connecting to the Power Supply
Use the following information to connect your HDR 650 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 650 power cable.
• 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 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.

CAUTION: Some boats have 24 or 36 Volt electrical systems. Make sure that your
HDR 650 is connected to a 12 VDC power supply. Use a voltage conditioner for
variable inputs.
NOTE: Humminbird® is not responsible for over-voltage or over-current failures. The
control head must have adequate protection through the proper selection and
installation of a 1 amp fuse.
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. Install a 1 amp fuse (not included) for protection of the unit.
Humminbird® is not responsible for over-voltage of over-current failures.

Transducer Installation Overview
Find the correct section for your transducer installation type. 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.
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.

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.
Turbulence: You must first determine the best
location on the transom to install the transducer. It
is very important to locate the transducer in an area
that is relatively free of turbulent water. Consider
the following to find the best location with the least
amount of turbulence:
Areas of Possible Turbulence
• As the 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" to the side of the
propeller(s) (see the illustration Turbulence-
Free Location).
Rivets
Transom
Strakes
Hull
Stepped Hull
Rib
Step
• 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 (see the
illustration Areas of Possible Turbulence).
Transom Mount Transducer Installation

• 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 (see the illustration Stepped Hull).
• 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, such as an Inside the Hull Transducer.
• If you plan to trailer your boat, do not mount the transducer too close to
trailer bunks or rollers to avoid moving or damaging the transducer during
loading and unloading of the boat.
• If high speed operation is critical, you may want to consider using an In-Hull
transducer instead of this Transom Mount transducer.
Turbulence-Free Location
Level
15”
Find a turbulence-free location at least 15” from the propeller(s) and not in
line with trailer bunks or rollers.
NOTE: The hydrodynamic shape of your
transducer allows it to point straight down
without deadrise adjustment.
Deadrise Angle
NOTE: If you cannot find a transom mount location that will work for your high-
speed application, find an In-Hull Transducer by contacting our Customer
Resource Center at either 1-800-633-1468 or by visiting our Web site at
humminbird.com.

2. Preparing the Mounting Location
In this procedure, you will determine the mounting location and drill two
mounting holes, using the transducer mounting bracket as a guide.
1. Make sure that the boat is level on the trailer,
both from port to starboard and from bow to
stern, by placing your level on the deck of the
boat, first in one direction, then in the other.
Positioning the
Mounting Bracket
Level
2. Hold the mounting bracket against the
transom of the boat in the location you have
selected. Align the bracket horizontally, using
the level; make sure that the lower corner of
the bracket does not protrude past the bottom
of the hull, and there is at least 1/4" clearance
between the bottom of the bracket and the
bottom of the transom for fiberglass boats, and
1/8" clearance for aluminum boats (see the
illustration Boat Hull Types Require Different
Mounting Positions).
Boat Hull Types Require
Different Mounting Positions
NOTE: If you have a flat-bottomed aluminum
boat, some additional adjustment may be needed
to accommodate the rivets on the bottom of the
boat (i.e. the gap may need to be a little smaller
than 1/8"). This will help you to avoid excessive
turbulence at high speeds.
1/4” for fiberglass
1/8” for aluminum
NOTE: If your propeller moves clockwise (in
forward, as you're facing the stern of the boat
from behind), mount the transducer on the
starboard side, and align the bottom right corner
of the mounting bracket with the bottom of the
boat. If your propeller moves counter-clockwise
(in forward, as you're facing the stern of the boat
from behind), mount the transducer on the port
side, and align the bottom left corner of the
mounting bracket with the bottom of the boat.

Using the Mounting Bracket
to Mark the Initial Drill Holes
3. Continue to hold the bracket on the transom of
the boat, and use a pencil or marker to mark
where to drill the two mounting holes. Mark the
drill holes near the top of each slot, making sure
that your mark is centered in the slot (see the
illustration Using the Mounting Bracket to
Mark the Initial Drill Holes).
4th hole
NOTE: The third hole should not be drilled until
the angle and height of the transducer is finalized,
which you will not do until a later procedure.
Mark Initial
3rd hole
Drill Holes
4. Make sure that the drill bit is perpendicular to the
actual surface of the transom, NOT parallel to the
ground, before you drill. Using a 5/32” bit, drill the
two holes only to a depth of approximately 1”.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce
the chance of chipping or flaking the outer coating.
3. Assembling the Transducer and Initial Mounting
In this procedure, you will assemble the transducer using the hardware provided,
then mount it and make adjustments to its position without locking it in place.
NOTE: You will initially assemble the transducer and the pivot arm by matching the
two ratchets to a numbered position on the transducer knuckle. Further adjustments
may be necessary.
1a. If you already know your transom angle, refer to the chart below for the
initial position to use to set the ratchets. If your transom is angled at 14
degrees (a common transom angle for many boats) use position 1 for the
ratchets. In either case, go to step 2. If you do not know your transom
angle, go to step 1b.

Measuring the Transom Angle
1b. If you do not know your transom angle,
measure it using a plumb line (weighted
nylon string or monofilament line) exactly 12
inches long. Hold the top of the plumb line
against the top of the transom with your
finger, and wait until the line hangs straight
down. Using a ruler, measure the distance
from the bottom of the plumb line to the
back of the transom, then use the chart.

2. Place the two ratchets, one on either side of the transducer knuckle, so
that the beads on each ratchet line up with the desired position number
on the knuckle (see the illustration Transducer Knuckle Positions). If you
are setting the ratchets at position 1, the beads on each ratchet will line
up with the rib on the transducer knuckle to form one continuous line on
the assembly (see the illustration Ratchets Placed in Position 1).
NOTE: The ratchets are keyed; make sure that the square teeth on each ratchet
face the square teeth on the transducer knuckle, and the triangular teeth face
outward.
Hold the ratchets on the transducer knuckle with one hand and fit the pivot
arm over them until it snaps into place with the other hand. Refer to the
illustration Fitting the Mounting Bracket Over the Ratchet.

3. Put the pivot bolt through the assembly to
hold it in position and loosely install the nut,
but do NOT tighten the nut at this time (see
the illustration Inserting the Pivot Bolt).
Insert the pivot arm assembly into the
mounting bracket (see the illustration
Inserting the Pivot Arm Assembly Into the
Mounting Bracket). Do NOT snap the
assembly closed, as you will need to access
the mounting bracket in the next step.
Inserting the Pivot Bolt
NOTE: If the pivot assembly is snapped closed over the mounting bracket, use a flat
head screwdriver or similar tool to gently pry the assembly away from the
mounting bracket (see the illustration Prying the Assembly Away from the
Mounting Bracket).

4. Align the mounting bracket transducer
assembly with the drilled holes in the
transom. With a 5/16" socket driver, mount
the assembly to the transom using the two
#10 - 1" long screws provided (see the
illustration Mounting the Assembly to the
Transom).

6. Adjust the initial angle of the transducer from back to front by rotating the
transducer until the side seam on the transducer is almost parallel with the
bottom of the boat, one click at a time in either direction (see the
illustration Adjusting the Initial Transducer Angle).

7. Adjust the transducer assembly vertically, until the seam on the leading edge
of the transducer (the edge closest to the transom of the boat) is level and
just slightly below the hull (see the illustration Adjusting the Transducer
Mounting Position).
NOTE: The transducer has a natural downward slant of 4-5 degrees from leading
edge (closest to the boat transom) to trailing edge (farthest away from the boat).
Looking at the back of the transducer, the seam should be slightly below the
bottom of the hull.
8. Continue to adjust until the bracket is also level from port to starboard
(horizontally level as you look at the transducer from behind the boat (see
the illustration Leveling the Mounting Assembly Horizontally).

9. Mark the correct position on the transom by tracing the silhouette of the
transducer mounting bracket with a pencil or marker.
10. Tighten the pivot bolt, using the pivot screw and nut to lock the assembly.
Hand tighten only!
11. Snap open the assembly and hand-tighten the two mounting screws, then
snap the assembly closed.
NOTE: You will drill the third mounting hole and finalize the installation after you
route the cable and test and finish the installation in the following procedures.
4. Routing the Cable
The transducer cable has a low profile connector, which 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 is 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 (if it
is already connected). Make sure that the cable is long enough to
accommodate the planned route by running the cable over the transom.
Transom Mount Transducer Installation

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'. For assistance, contact the Customer Resource Center at humminbird.com
or call 1-800-633-1468 for more information.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough
slack in the cable for this movement. It is best to route the cable to the side of the
transducer so the transducer will not damage the cable during movement.
2a. If you are routing the cable over the transom of
the boat, secure the cable by attaching the
cable clamp to the transom, drilling 9/64"
diameter holes for #8 x 5/8" wood screws, then
skip directly to procedure 5, Connecting the
Cable.
Routing the Cable
or...
2b. If you will be routing the cable through a hole
in the transom, drill a 5/8" diameter 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 (see the illustration Routing the
Cable).
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" diameter x 5/8" deep
holes, and 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" wood screws.

4. Route and secure the cable by attaching the cable clamp to the transom;
drill one 9/64" diameter x 5/8" deep hole, then fill hole with marine-grade
silicone sealant, then attach the cable clamp using a #8 x 5/8" screw.
Storing Excess Cable
NOTE: If there is excess cable that needs to be
gathered at one location (as shown in the
illustration), dress the cable routed from both
directions so that a single loop is left extending from
the storage location. Doubling the cable up from this
point, form the cable into a coil. Storing excess cable
using this method can reduce electronic interference
(see the illustration Storing Excess Cable).
5. Connecting the Cable
If you unplugged the transducer cable at the beginning of this procedure, plug it
back into the depth sounder.
NOTE: The connector is keyed to prevent reverse installation, so be careful not to
force the plug into the connector the wrong way.
6. Test and Finish the Installation
Once you have installed both the HDR 650 and the transom transducer, 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.
1. Turn on the power source to power up the HDR. If the unit does not power
up, make sure that the connector holder is fully seated in the receptacle
and that power is available.
2. If all connections are correct and power is available, the Humminbird®
control head will enter Normal operation.
3. If the digital depth readout displays on the screen, the unit is working
properly. Make sure that the boat is in water greater than 2' but less than
the depth capability of the unit, and that the transducer is fully submerged,
since the sonar signal cannot pass through air.

NOTE: The transducer must be submerged in water for reliable transducer
detection.
4. If the unit is working properly, gradually increase the boat speed to test
high-speed performance. If the unit functions well at low speeds, but
begins to skip or miss the bottom at higher speeds, the transducer requires
adjustment.
5. If you have the correct angle set on the transducer, yet lose a bottom
reading at high speed, adjust the height and the running angle in small
increments to give you the ideal transducer position for your boat. First,
adjust the height in small increments (see the illustration Adjusting the
Transducer Mounting Position).

NOTE: The deeper the transducer is in the water, the more likely that a rooster tail
of spray will be generated at high speeds, so make sure that the transducer is as
high as it can be and still be submerged in the water.
If you are still not getting good high speed readings, you may need to
disassemble the transducer mounting assembly and re-position the ratchets
(see the illustrations Transducer Knuckle Positions, Ratchets Placed in
Position 1, Ratchets Placed in Position 2, and Fitting the Mounting
Bracket Over the Ratchet).

If you do change the transducer position, re-trace the position of the mounting
bracket before proceeding.
NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved. Due to the wide variety of
boat hulls, however, it is not always possible to obtain high speed depth readings.
6. Once you have reached a consistently good sonar signal at the desired
speeds, you are ready to lock down the transducer settings. Force the pivot
to the Up position to gain access to the mounting screws, then re-align the
mounting bracket against the transom of the boat to match the traced

Inside the Hull Transducer Installation
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.
WARNING! 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 depth sounder.
1. Locating the Transducer Mounting Position
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.
Inside the Hull Transducer 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 depth sounder, then power up the depth
sounder. When the depth sounder detects a functioning transducer, it will
automatically enter Normal operating mode.
Positioning the Transducer
Preferred Mounting Area
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 (see the illustrations
Positioning the Transducer and Preferred Mounting Area).
Inside the Hull Transducer Installation

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 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 depth sounder. 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.
3. Routing 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 depth
sounder.
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
humminbird.com or call 1-800-633-1468 for more information.

4. Permanently Mounting the Transducer
NOTE: Once permanently mounted, you will not be able to make further
adjustments to the transducer.
1. Make sure the position of the transducer is
marked.
Coating the Transducer with Epoxy
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.
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 (see the
illustration Coating the Transducer with
Epoxy).
Pressing the Transducer Into Place
5. Press the transducer into place with a
slight twisting motion to purge any
trapped air from underneath, keeping the
pointed end of the transducer body
pointed forward, towards the bow (see the
illustration Pressing the Transducer Into
Place).
NOTE: Proper operation requires the
pointed end of the transducer body to face
towards the bow.
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 depth sounder.
NOTE: The connector is keyed to prevent reverse installation, so be careful not
to force the plug into the connector the wrong way.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the
transducer.
Trolling Motor Transducer Installation
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.
Trolling Motor Transducer Options
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.
NOTE: There are also several transducer switches available that support the
configuration of two depth sounders with one transducer or two transducers with
one depth sounder.
NOTE: Call the Humminbird® Customer Resource Center at 1-800-633-1468 for
details and pricing, or visit humminbird.com for more information.

Operating the HDR 650
Your HDR 650 Digital Depth Sounder 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 650 transducer
receives sonar signals, it converts them to a digital depth that is shown on the
HDR 650 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.
NOTE: Actual depth capability depends on such factors as bottom hardness, water
conditions, and transducer installation. Units will typically read to deeper depths in
fresh water than in salt water.
The HDR 650 Control Head
The HDR 650 uses a backlit display, together with a 3-button keypad, to control
all user functions. The illustration below shows an example of the digital display.

Maintenance
To keep both your HDR 650 and your transducer working properly, perform the
following maintenance tasks as needed.
HDR 650 Maintenance
If your HDR 650 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 650 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 650 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.
HDR 650 Doesn't Power Up
If your HDR 650 doesn't power up, refer to the Installation section, and make
sure that:
• the power cable is properly connected to the HDR 650;
• 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 20 VDC.
Correct any known problems, including removing corrosion from the battery
terminals or wiring, or actually replacing the battery if necessary.
Troubleshooting

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 650 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.
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 650 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.
