ACCESSORIES
Humminbird offers a wide assortment of accessories that complement and expand the
capability of your new fishfinder. These accessories are designed with the same high
standards and are backed by the same one-year warranty. The Humminbird Accessory
catalog included with your unit contains descriptions of the many accessories available
and ordering information. All Humminbird accessories are available through your full-
service Humminbird dealer or factory direct through our number listed in the Customer
Support section.
INSTALLATION OVERVIEW
Your Humminbird fishfinder consists of two primary components to install: the control
head and the transducer.
The control head contains the sonar transmit and receive circuitry, as well as the user
controls and display. It should be installed in a location that provides access to the
controls and visibility while in use. The control head mounts on a quick disconnect
mounting system that swivels and tilts providing flexibility for viewing from almost
anywhere on the boat.
The transducer 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 control head. It should be installed in
contact with the surface of the water in an area that has smooth waterflow- usually on
the transom of the boat. There are several mounting options for the transducer. Review
the following section to determine the method that works for you and your boat.

INSTALLATION PREPARATION
INSTALLATION OVERVIEW
Determining How to Mount the Transducer
Your Humminbird fishfinder includes a standard
transducer. This transducer can be mounted on the
transom of the boat or bonded to the inside of a fiberglass
hull boat.
The transom installation, which is the most widely used,
places the transducer on the outside of the boat hull. This
technique produces the least signal loss, and provides a
way to adjust the transducer after installation. The
mounting hardware included is designed to protect both
the boat and the transducer should the boat strike debris in
the water or when trailering.
As an alternative to transom mounting, it is possible on many
fiberglass-hulled boats to glue the transducer on the inside of
the boat hull. Since fiberglass has similar sonar
characteristics as water, the sonar signal can pass through
the boat hull with minimal loss. The hull of the boat must be
single layer construction (not double-hulled) Also, any air
trapped in the lamination of the fiberglass would prevent the
sonar signal from passing through.
Inside the hull installations require no holes be drilled into the
boat and through experimentation, high-speed operation
comparable to transom mounting can be achieved. Two-part slow cure epoxy (not
included) is required to glue the transducer in place.

INSTALLATION PREPARATION
ALTERNATE MOUNTING METHODS
ALTERNATE TRANSDUCERS AND MOUNTING METHODS
Your Humminbird fishfinder comes with everything necessary for installation and
operation on most boats. However, there are several situations which may require a
different type of transducer. Inboard boats, wood or metal hulls, and sail boats create
unique transducer mounting needs Alternate transducers and mounting methods are
detailed below.
Portable Mounting
The standard transducer can be adapted for portable
installations with a portable mounting kit available from
Humminbird. This accessory adapts your transducer to a
suction cup mount for temporary installation on the boat hull
or other surface.
Trolling Motor Mounting
The standard transducer can also be adapted to mount on
most trolling motors using a different accessory kit. This
accessory includes a bracket and hose clamp that allows
mounting the transducer to the body of most trolling motors.
Thru-Hull Mounting
Thru-hull transducers install through a hole drilled in the hull
of the boat. Larger boats or boats with inboard motors create
turbulence that make transom mounting ineffective. Also,
hulls that are very thick or are double layered, or made from
materials such as wood or metal, (which do not conduct
sonar signals) make inside the hull mounting inadvisable.
Thru-hull mounting may require the use of a fairing block to level the transducer with the
waterline. Also, since special tools and knowledge may be required to perform this type
of installation, it is best to refer to a qualified marine technician.

INSTALLATION
TRANSOM INSTALLATION
Do not begin this transducer installation until you read the Installation
Preparation in the Operation Guide. This chapter contains information critical to
the correct installation of your transducer.
Due to the wide variety of boat hulls, only general instructions are presented in
the installation guide. Each boat hull represents a unique set of requirements that
should be evaluated prior to installation.
TRANSOM INSTALLATION
Step One - Determine Where to Mount the Transducer
Begin the transducer installation by determining where 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). 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) (Figure 1). On outboard or inboard/outboard
boats it is best to stay at least 15” (40cm) to the side of the
propeller(s).
If possible, viewing the transom of the boat while the boat is
moving will provide the best means of locating turbulence free
water. If maximum high-speed operation is a high priority, this
is the recommended method. 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 transducer when mounted should point straight down.
The design of the transducer will accommodate a wide range
of deadrises and remain ported straight down (Figure 2).
On boats with stepped hulls, it may be possible to mount the transducer on the step.
Never mount the transducer on the transom behind a step, as this area of the
transom will not be in contact with the water at high speed (Figure 3).

INSTALLATION
TRANSOM INSTALLATION
·
If the propeller(s) is (are) forward of the transom, it may be impossible to find an
area clear from turbulence, and a different mounting technique or transducer type
should be considered.
Step Two - Drill the Mounting Holes
1. Remove the mounting template from the front of the Operations Manual.
2. Hold the template on the transom of the boat in the location where the transducer
will be installed (Figure 4). Align the template vertically, ensuring the lower edge of
the transom meets with the bottom corner of the template.
3. Using a pencil or punch, mark the two mounting holes
shown on the template onto the transom. Do not mark or
drill any other holes at this time.
4. Using a 5/32” (4mm) bit drill the two holes to a depth of
approximately 1" (3cm). On 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.
Step Three - Assemble the Transducer
1. Attach the Pivot to the transducer body as shown in Figure
5, using the #8 – 3/8” (9mm) long allen headed pivot screw,
the headed pin, the two flat washers, and the two toothed
lock washers.
Note: The toothed lock washers must be positioned
between the transducer and the pivot ears. The flat
washers must be positioned to the outside at the pivot
ears.
2. Using the AIlen wrenches provided, loosely tighten the pivot
screw (Figure 6). Do not completely tighten the assembly at
this time, so the pivot angle can be adjusted later.
3. Insert the pivot/transducer assembly into the mounting
bracket as shown in Figure 7. Do not snap the assembly
closed.

INSTALLATION
TRANSOM INSTALLATION
Step Four - Mount the Transducer to the Transom
1. Apply silicone sealant to the mounting holes drilled into the transom.
2. Align the transducer assembly with the drilled holes in the transom (Figure 8).
3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm)
socket to mount the assembly. Using the two #10 – 1”
(25mm) long slotted hex head screws, mount the transdu
assembly to the transom as shown. Do not fully tighten th
mounting screws in order to vertically adjust the transduc
Snap the pivot down into place.
Step Five - Adjust the Running Position of the Transduc
The bracket allows height and tilt adjustment, the pivot sc
allow angular adjustment. Initially, adjust the transduce
described in the following paragraphs. Further adjustment
be necessary to refine the instillation after high speed testing
1. First adjust the pivot angle of the transducer body so its
length is parallel with the length of hull of the boat. Then
pivot the transducer down so the rear is about 1/4 inch
(6mm) lower than the front (Figure 9).
2. Fully tighten the two pivot screws using the Allen wrench
It may be necessary to retighten the pivot screws after th
initial use as the plastics may still be seating to the lock
washers.
3. Adjust the height of the assembly so the face of the
transducer is 3/16" (4.5mm) beneath the lower edge of th
transom (Figure 10). Mark the position of the mounting
bracket on the transom with a pencil.
4. Force the pivot to the up position to gain access to the
mounting screws. Assure the transducer location has not
changed, then fully tighten the two mounting screws (Fig
11). Snap the pivot back down.
Confirm the pivot angle has not changed.
Note: A third screw location is provided for the
mounting bracket. Drill this hole and install the screw after final testing and
adjustments have been completed.

INSTALLATION
TRANSOM INSTALLATION
Step Six - Route the Cable
There are several ways to route the transducer cable to the to the area where the
control head will be installed. The most common procedure routes the cable through the
transom into the boat.
Inside the boat there is often a channel or conduit used for other
wiring that the cable can be routed along. Do not cut or shorten
the transducer cable and try not to damage the cable insulation.
Route the cable as far as practical from the VHF radio antenna
cables or tachometer cable 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). Call Humminbird
Customer Support for more information.
Follow these steps to route the cable through the transom:
1. Drill a 5/8” (16mm) hole above the water line. Route the
cable through the hole.
2. Fill the hole with silicone sealant.
3. Place the escutcheon plate over the hole and attach with the two #8 x 5/8” (16mm)
screws.
4. Secure the cable by attaching the cable camp to the transom using a #8 x 5/8”
(16mm) screw.
Note: The transducer will 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 cable will not be damaged by the transducer during movement.

INSTALLATION
INSIDE THE HULL INSTALLATION
INSIDE THE HULL INSTALLATION
Inside the hull installation requires the mount system and control
head be installed and operational. See Installing the Control Head
for instruction on installing the unit.
Inside the 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, and the installation.
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. Five minute epoxy has
a tendency to cure before all the air bubbles can be purged.
Step One - Determine the Mounting Location
Begin the transducer installation by determining where inside the
hull to install the transducer. 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 (Figure 14).
·
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 to remain in contact with the water at high speeds.
Step Two - Test the Mounting Location
There is no opportunity for adjustment after the transducer glued in place. Therefore, it
is best to perform a trial installation on inside the hull transducers first, and run the boat
at high speeds to determine the best mounting area.
1. At the identified mounting location, lay the transducer body face down with the
pointed end towards the bow.
2. 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. The water purges any air from between
the transducer and the hull and fills any voids in the coarse fiberglass surface.

INSTALLATION
INSIDE THE HULL INSTALLATION
3. Power up the Control Head.
4. Run the boat at various speeds and water depths while observing the screen on the
Control Head. If the unit functions well at low speeds but begins to skip or miss the
bottom at higher speeds, the transducer needs to be moved. If depth performance is
required, test the fishfinder in water at the desired depth. Test different locations in
the hull until the optimum performance is achieved.
Step Three - Permanently Mount the Transducer
1. Once the mounting location is determined, mark the position of the transducer.
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.
Ensure the mounting area is clear and dry.
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 (Figure
16).
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 (Figure 17).
Note: Proper operation requires the pointed end of the
transducer body to face towards the bow.
6. Weight the transducer so it does not move while the epoxy is curing.
When the epoxy cures, no water is necessary inside the hull. Neither water, spilled
gasoline, or oil will affect the performance of the transducer.

INSTALLATION
CONTROL HEAD INSTALLATION
CONTROL HEAD INSTALLATION
Step One - Determine Where to Mount
Begin the installation by determining where to mount the control head. Consider the
following to determine best location:
·
The cables for power, transducer and temp/speed accessories (if applicable) should
be installed first and must reach the mounting location. Extension cables are
available.
·
There are two ways to route the cables to the unit: through a
hole in the mounting surface underneath the mounting bracket
or from a hole outside the mounting bracket. Routing the cables
down under the mount provides maximum weather protection;
however this is not always feasible if the area under the
fishfinder is inaccessible. In this case, route the cables through
a hole at another location and cover with the supplied hole
cover.
·
·
The mounting surface should be adequately supported to
protect the fishfinder from excessive wave shock and vibration,
and provide visibility while in operation.
The mounting area should allow sufficient room for the unit to
pivot and swivel freely, and for easy removal and installation
(Figures 18-19).
Step Two - Connect the Power Cable to the Boat
A 6’ (2m) long power cable is included to supply power to the
fishfinder. You may shorten or lengthen the cable using 18 gauge
multi-stranded copper wire.
CAUTION: Some boats have 24 or 36 volt electric systems. Be
sure your unit is connected to a 12 VDC power supply.
The Power can be connected to the boat's electrical system at two
places: a fuse panel, usually located near the console, or directly to the battery.
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 (Figure 20). Be sure to use a one amp fuse in the connection. If you
must wire the control head directly to a battery, be sure to install an inline fuse holder

INSTALLATION
CONTROL HEAD INSTALLATION
and one amp fuse (not included) for the protection of the unit (Figure 21). Humminbird is
not responsible for over voltage or over current failures.
In order to minimize the potential for interference with other
marine electronics a separate power source (such as a
second battery) may be necessary.
Step Three - Drill the Mounting Holes
1. Set the mounting bracket in place on the mounting
surface. Mark the four mounting screw locations with a
pencil or punch.
2. Set the mounting bracket aside, and drill the four
mounting screw holes using a 9/64” (3.6mm) bit.
Step Four - Run the Cables
1. If the cables must pass through a hole underneath the
mounting surface, mark and drill a 1” (25mm) hole
centered between the four mounting holes (Figure 22).
Note: if the cables must pass through the mounting
surface at a different location, drill the 1" (25mm) hole at
that location and pass the cables through from
underneath. Also, you must break out the tabs on the
rear of the mounting base using needle nose pliers
(Figures 24-25).
2. Insert all cables through the 1” (25mm) hole from beneath
the mounting surface.
3. Pass the cables through the grommet (if the cable hole is
underneath the mounting bracket) then press the grommet
in place around the cables and into the 1” (25mm) hole.
4. Pass the cables through the mounting base, out the top of the mounting bracket.
5. Place the mounting bracket on the mounting surface aligned with the drilled holes.
Insert the four flathead wood screws into the mounting holes and tighten fully (Figure
23).
Optional: If the cables pass outside the mounting bracket, install the hole cover
over the hole and fasten in place using the two #8 x 7/8” (22mm) wood screws
(Figure 24).

INSTALLATION
CONTROL HEAD INSTALLATION
Step Five - Assembling the Connector Holder
1. Insert the cable connectors into the connector holder.
The cable connectors are labeled, and there are
corresponding labels on the connector holder (Figure
26). The slots for the connectors are keyed to prevent
reverse installation, so do not force the connector into
the holder.
2. Carefully pull the excess cable from beneath the -
mounting surface so the connector holder aligns with the
mounting holes on the front of the mounting bracket
(Figure 27).
3. Snap the support plate to the rear of the connector
holder (Figure 28).
4. Insert the connector holder into place and use the two
#6-32 x ¾” (9mm) screws to fasten it to the mounting
bracket (Figure 28).
5. Install the control head by sliding it onto the mounting
bracket until it is fully seated. To remove the unit simply
depress the latch on the rear of the unit and lift (Figure
29).
Your Humminbird is now ready for operation.

INSTALLATION
TEST THE INSTALLATION
TEST THE INSTALLATION
Testing should be performed with the boat in the water, however you can initially
confirm basic operation with the boat trailered.
Press POWER once to turn the unit on. There will be an audible chirp when any button
is pressed to confirm the button press. If the unit does not power-up, ensure the unit is
fully seated on the mount and that power is available.
The first screen provides four options: Start-up, Options, Simulator, and Diagnostic. A
message at the bottom of the screen indicates the transducer connection. If no
transducer is detected (or one is not connected), the message will indicate this and the
unit will go into simulator after the initial screen times out.
Note: the transducer must be submerged in water for reliable transducer
detection.
If a transducer is detected, the unit will enter “Start Up” or normal operation unless you
choose another option. If you do not press any button before the timer reaches “0”, the
normal operation screen is displayed. If the boat is in water, sonar data appears.
If the bottom is visible on screen with a digital depth readout, the unit is working
properly. Ensure the boat is in water greater than 2’ but less than the depth
capability of the unit and the transducer is fully submerged. Remember the sonar signal
cannot pass through air.
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. Refer to the appropriate
transducer installation section for more detail.
Note: it is often necessary to make several incremental transducer adjustments
before optimum high-speed performance is achieved.
Important: For Transom Mount transducer installations, install the third mounting screw
after the final transducer adjustments.

USING THE 200DX
HOW SONAR WORKS
HOW SONAR WORKS
Your Humminbird unit uses sonar to locate and define
underwater objects, define the bottom terrain, as well as
determine distance.
Sonar technology is based on sound waves. Your
Humminbird unit sends out a sound wave signal. With this
signal it determines distance by measuring the time
between the transmission of the sound wave and when the
sound wave is reflected off an object. Your Humminbird
uses the reflected signal to interpret location, size and
composition of an object.
Sonar is very last. A sound wave can travel from the surface to a depth of 240’ (70m)
and back again in less than 1/4 of a second. It is unlikely that your boat can “outrun" this
sonar signal.
The 200DX is a dual frequency, dual beam unit, and generates two distinct sonar
signals - one narrow, one wide. Each signal is optimized for a particular purpose. First,
the center beam transmits at a frequency of 200kHz in a 20 degree (narrow)
symmetrical pattern for greater depth capability and excellent detail. Information from
this center beam is used to draw the graphic representation of the bottom on the
display.
Second, the wide beam transmits at a frequency of 83kHz in a 53 degree (wide)
symmetrical pattern for greater area of coverage. Information from the wide beam is
used to accurately detect the presence and location of fish. A wide beam has a large
area of (coverage but limited resolution of detail. A narrow beam has excellent detail,
but within a limited area of coverage.
The combination of the two beams and dual frequencies provides the combination of a
large area of coverage and a high level of detail.

USING THE 200DX
SIMULATOR OPERATION
Actual depth capability depends on factors such as bottom hardness, water conditions,
and transducer installation. Unit will typically read to deeper depths in fresh water than
in salt water
SIMULATOR OPERATION
The 200DX contains a simulator that allows you to use the unit
as if you are on the water. The simulator is invaluable or
learning how to operate the 200DX.
There are two ways to start the simulator. If the unit is powered
off, press and hold the POWER button for approximately three
seconds until you hear a continuous chirp.
The simulator can also be started by selecting the Simulator option on the start-up
screen after you power-up the unit. When this screen is shown, simply press the DOWN
ARROW until Simulator is highlighted. When the screen times out, the unit will be in
simulator mode.
When in simulator operation, the 200DX responds to control inputs as if it is in actual
operation, so feel free to experiment or to customize the unit for your particular
operation.
To exit Simulator mode, power the unit off.
When in simulator mode, the word "simulator" occasionally scrolls across the
display indicating the information on-screen is not real sonar data.
FEATURE MEMORY
If your 200DX is installed with a transducer connected, any changes you make to the
set-up or User Options (see Control Functions) while in Simulator are retained in the
unit memory. This allows you to use simulator to experiment with the various set-up
options and retain your selected settings for normal operation.

USING THE 200DX
WHAT YOU SEE ON-SCREEN
If you are using the 200DX in Simulator when no transducer is connected, any selected
options are lost when the unit is powered off. The 200DX will return to Factory Settings,
or options selected when last used with a transducer, if no transducer is connected.
IMPORTANT: A transducer must be connected to the 200DX in order to retain user
settings selected when in simulator mode. If no transducer is detected the unit defaults
to pre-selected options when powered off.
What You See On-Screen
Your 200DX uses a 128 x 64 matrix FSTN LCD display.
This display provides outstanding viewability in all light
conditions over a wide range of temperatures.
At initial power-up, the 200DX uses settings that were set at
the factory. After initial use the 200DX will remember the
settings you enter.
Them are several elements on-screen that are common to
all modes of operation.
Temperature/Speed. The initial screen layout takes one of two basic forms depending
on whether the optional Temp/Speed accessory is installed. Figure A shows the default
view when the Temp/Speed accessory is installed. Figure B shows the default view
when the Temp/Speed accessory is not installed.
Depth. The digital depth number shows the water depth directly beneath the transducer
location.
Depth Range. The depth range is shown to the right of the screen. The upper number
is 0 indicating the surface of the water. The lower number is one of the nine depth
ranges available that best matches the depth of the water. As the depth of the water
changes the range changes as necessary in order to retain a bottom representation on-
screen.
Download from Www.Somanuals.com. All Manuals Search And Download.
USING THE 200DX
WHAT YOU SEE ON-SCREEN
When in Auto mode, the horizontal line at the top of the
screen is the “zero line,” representing the surface of the
water. Occasionally there is a gap in this line. This gap
indicates the unit is updating the display even if the bottom is
not visible on-screen or if the bottom information is not
changing.
New sonar information appears on the right side of the
graphic area of the display and moves to the left as new
information is displayed. The 200DX automatically selects the
appropriate depth range to show the depth of water beneath
the transducer. This range is selected so the bottom
representation is typically shown about 2/3 down the display.
Bottom. The graphic depiction or the bottom provides an
effective tool for understanding the composition of the bottom.
If the bottom is hard and smooth the bottom depiction is
narrow and dense. If the bottom is soft mud or sand, the
depiction will be thick and less dense. This indicates much of
the signal is absorbed by the soft bottom. It the bottom is
rocky or rugged in composition the depiction is of varying
density and textured in appearance.
Wave action also affects the bottom depiction. The
information drawn is a distance measurement so if the boat is
moving up and down over flat bottom, the bottom depiction
often appears in regular variations that match wave timing.

USING THE 200DX
WHAT YOU SEE ON SCREEN
Structure. Structure is defined as any object physically attached to the bottom. The
sonar configuration of the 200DX is optimized to give the most accurate depiction of
bottom structure possible. Grass, trees, stumps, wrecks or other debris are accurately
displayed, however the depiction or these objects varies with boat speed and direction.
The best way to learn to interpret structure is to operate the 200DX over a variety of
known conditions and experiment with user functions to best represent those conditions
on-screen.
Surface Clutter. Surface clutter is the layer or water near the surface that is rich in
algae and other growth and often it aerated by wind or wave action. This area of water
interferes with sonar transmission and often appears on-screen as regular clusters of
individual dots near the 0 line.
Thermoclines. Thermoclines are sharp differences in water
temperature. These are easily identified by the continuous
nature of the return.
Second Returns. When a sonar signal is reflected off the
bottom back to the transducer there is often enough energy
left in the signal to be reflected off the surface of the water
back to the bottom a second time. Second returns appear
as a slightly weaker bottom representation exactly twice the
depth of the primary bottom return. The second return is
most likely to occur in shallow water and in areas of
relatively hard bottom.

USING THE 200DX
CONTROL FUNCTIONS
Fish ID. The 200DX uses advanced signal processing to
further evaluate any sonar return between the surface and
the bottom. For instance a small school of Bait fish usually
appears as a dense cluster of individual dots. If the return
meets certain additional criteria, a fish symbol is assigned.
There are three different size fish symbols used to indicate
the intensity of the sonar return. While signal intensity is a
good indicator of relative fish size, different species of fish
have different sonar characteristics, so it is not always
possible to distinguish fish size between varying species.
The signal intensity is normalized for depth so a small fish
close to the boat does not appear as a large fish symbol.
ID+ adds an additional piece of information to help the user
locate fish. On selected fish symbols the digital depth of the designated fish is drawn to
help locate the fish vertically.
The fish symbols indicate the sonar beam the fish is detected in. This gives you a
reliable indicator of side to side location of the fish relative to the boat. Fish symbols that
are hollow are detected in the wide beam and are around the boat. Solid fish symbols
represent fish detected in the narrow beam and are directly under the boat.
CONTROL FUNCTIONS
The 200DX uses a simple five button keypad for all user input. Press
any button and an audible “chirp” confirms the control input. If a
button has no function or is inappropriate for the situation an audible
error is heard. The unit sounds multiple chirps.
Power. The Power button powers the 200DX up for normal operation.
When the unit is on, POWER turns the unit off. POWER can also be
used to go directly into Simulator mode To enter simulator, with the
unit powered off, press and hold POWER for several seconds until a
continuous chime is heard.

USING THE 200DX
CONTROL FUNCTIONS
Light. LIGHT controls the unit's display backlight. With the unit powered on, press
LIGHT once to turn the backlight on “high." Press LIGHT a second time to turn the
backlight on “low,” and a third time turns the backlight off. The backlight is very effective
for low-light and nighttime operation. When the backlight is on the 200DX will consume
more power than with the backlight off. This is important when using the 200DX in a
portable configuration powered by a separate battery, or when powering the unit from a
trolling motor battery.
When powering the unit from a battery such as in portable applications, you can prolong
the battery life by using the backlight at a minimum.
The three lower buttons, MENU, UP ARROW, and DOWN ARROW work together to
control the 200DX menu-controlled user functions.
Menu. MENU displays a menu on-screen for adjustment. In
normal operation, pressing MENU repeatedly cycles through all
available menu headings. When a menu heading displays the full
menu appears after a short pause. A menu remains on-screen for
several seconds and can be adjusted by using the ARROW keys. If no adjustment is
made in the allotted time, the menu disappears. If you want the menu to remain on-
screen longer, press and hold MENU ¾ the menu will remain on-screen indefinitely.
Once you release the menu button, the screen will time out. Once a menu times out, it
is still considered the active menu. Press MENU to bring up the last menu used.
Arrow Keys. The UP ARROW and DOWN ARROW make adjustments to menu
functions. On the left side of every menu there are UP ARROW and DOWN ARROW
symbols. The symbols indicate which ARROW button has a function in a particular
situation. Either one or both ARROW buttons can be used to adjust the menu function.
A hollow ARROW symbol means the corresponding ARROW button has no function.
Pressing that button will result in no adjustment and the error audible will be heard.

USING THE 200DX
CONTROL FUNCTIONS
A solid ARROW symbol means the corresponding ARROW button can be used to affect
the menu adjustment.
The ARROW buttons often can be used when no menu is on-screen. In these
situations, pressing the ARROW button affects the function of the active (last-used)
menu. This is a short-cut to menu operation. The menu appears on-screen while the
adjustment is made and times out. A frequently used menu can
be adjusted very quickly using this technique.
After an adjustment is made to a menu function, the menu
times out after a few seconds and the unit returns to normal
operation.
Menu Layout. All menus use the same basic layout. The shading at the top describes
the menu function. The UP ARROW and DOWN ARROW symbols to the left of the
menu indicate which buttons are available for adjustment. In menus that have several
possible settings, a range of adjustment indicator shows the total range available and
the current setting.
Within the menu are the options available. The selected option or current setting is
highlighted in the black box. If no adjustment is made this is the selected setting. Press
an ARROW button while the menu is displayed to select another option.
Several of the menus are multi-step. In some situations if an adjustment is made,
additional options become available for further adjustment. Examples of these multi-
step menus are Depth Range, Depth Alarm, and Zoom. See the detailed description of
each function for further explanation.

USING THE 200DX
MENU FUNCTIONS
Menu Functions
Sensitivity. The Sensitivity function controls the sensitivity of the
sonar receiver. The 200DX automatically adjusts the level of
receiver sensitivity based on a number of factors including the depth
of the water and the level of noise present. Noise can be caused by
other electronic devices, engines, trolling motors, propeller
cavitation, and hydrodynamic flow among others.
The user has the option of adjusting the Sensitivity higher or lower based or personal
preference. You can select one of 11 sensitivity settings from -5 to +5. A setting of 0
(factory setting) has no effect on the automatic sensitivity control. Increasing the
sensitivity (+1 through +5) enables the Unit to display the information from progressively
smaller sonar returns. By decreasing the sensitivity bias (-1 through -5) the unit
effectively filters small sonar returns.
In murky or muddy water it is often helpful to reduce the
sensitivity. This prevents the display from being cluttered
with sonar returns from debris or suspended particles. In
very clear or very deep water, it may be helpful to increase
the sensitivity since even the smallest sonar return may be
of interest to the user.
To adjust Sensitivity, press MENU repeatedly until the
Sensitivity heading is displayed. When the Sensitivity menu
appears, use the UP ARROW to increase the sensitivity or
the DOWN ARROW to reduce sensitivity. To sequence
through the available settings, press and hold either
ARROW button. Release the button at the setting you want
to change.

USING THE 200DX
MENU FUNCTIONS
After an adjustment is made, the menu disappears and the new sensitivity setting is in
effect. If additional time is needed to study a menu press and hold the MENU button
and the menu will remain on-screen indefinitely. If you need to make an additional
adjustment, press the UP ARROW or DOWN ARROW button.
Depth Range. The Depth Range function controls the vertical
distance displayed on the graphic area of the display. There are
nine depth ranges available. The top of the range is always 0, or
the surface of the water. Ranges of 0-15’, 0-30’, 0-60’, 0-120’, 0-
180’, 0-240’, 0-360’, 0-480’, and 0-600’ are available. In the metric
version, ranges of 0-5, 0-10, 0-20, 0-40, 0-60, 0-80, 0-110, 0-150, and 0-185 meters are
available. The range that positions the bottom depiction closest to the bottom of the
screen, will best utilize the available display resolution.
The 200DX automatically adjusts the depth range depending on
the depth of the water. The unit tries to maintain the bottom
depiction about 2/3 down the total range (for example, in 20' (6m)
of water the 0-30' (0-10m) range would be selected). This
provides the best display resolution and therefore the best target
separation possible.
The Depth Range can be adjusted manually. Press MENU repeatedly until the Depth
Range menu is visible. Two options are available: Auto and Manual.
The manual setting enables you to adjust the current depth range
setting. The unit no longer adjusts the Depth Range to the most
appropriate range for bottom display. Often, the bottom may not be
visible on-screen. The digital depth readout always determines the
depth of the bottom, even it is not visible on-screen.

USING THE 200DX
MENU FUNCTIONS
Using manual Depth Range control, you can view sonar
information from the area near the surface in great detail.
To return to automatic Depth Range control, press the
MENU button until the Depth Range menu appears on-
screen and use the UP ARROW to select AUTO.
Zoom. Zoom is similar to Depth Range because it controls
the range of information displayed on screen. Zoom,
however, allows selection of ranges beneath the surface so
any area of water between the surface and the bottom can
be enlarged to provide more detailed information. By using
the full display to show a small area of coverage, the
effective display resolution is increased and the unit’s ability
to separate close targets is enhanced.
There are four Zoom ranges available: 7 ½’ (2m), 15’ (5m),
30’ (10m), and 60’ (20m). These ranges are not directly user
controlled but are instead dependent on the current depth
range. In shallow water, when the 15’ (5m) or 30’ (10m)
range is in use, the Zoom range is 7 ½’ (2m). If the 60’
(20m) or 120’ (40m) range is in use, the Zoom range is 15’
(5m), if a 180’-480’ (60-150m) depth range is in use, the
Zoom range is 30’ (10m), and if a 600’ (185m) range is in
use, the Zoom range is 60’ (20m).
Download from Www.Somanuals.com. All Manuals Search And Download.
USING THE 200DX
MENU FUNCTIONS
The Zoom range is shown on the Ieft side of the screen and full range
information is shown on the right side of the display. Zoom can either
operate automatically, in which the Zoom range is constantly adjusted
to show the bottom, or manually, in which the user controls the
location of the Zoom range.
Automatic Zoom is especially helpful when looking for structure or
bottom detail. The Automatic Zoom keeps the bottom in view even in quickly changing
terrain, but is most useful in flatter areas without considerable depth variation. Manual
Zoom provides detailed information of any area from the surface to the bottom. In
manual Zoom, the Zoom range does not move as the terrain changes.
When the range is shown in the menu, the upper number represents the top of the
current Zoom range. The lower number represents the bottom of the Zoom range. Use
the UP and DOWN ARROW buttons to move this range. The upper number can never
be less than 0 (the surface of the water), and the lower number can never be greater
than the active depth range. The difference between the two numbers (the Zoom range)
is preset and determined by the active depth range.
Once manual Zoom is selected, the display appears the same as in Auto Zoom, but the
zoom range does not change automatically.
To disable Zoom, press the MENU button until the Zoom menu is on-screen. Use the up
ARROW to highlight Off, and let the menu time out.
When the unit is powered off, the Zoom menu returns to Zoom Off.

USING THE 200DX
MENU FUNCTIONS
Depth Alarm. The 200DX contains an audible alarm to
warn you of shallow water depths. The alarm is
adjustable to depths of 2’(.6m) to 99’ (30m). When the
alarm is enabled, an audible alarm sounds if the water
beneath the boat is equal to or less than the selected
alarm depth. The alarm sounds continuously for about
five seconds and then intermittently to remind you that
you are still in shallow water.
Fish Alarm. The Fish Alarm alerts you to the presence of
fish, or other targets not connected to the bottom. The
Fish Alarm has three different settings that correspond to
the three different size fish symbols shown on-screen.
The default setting is “OFF.” With the “Large fish only”
setting, the 200DX alarms on only those targets that are
represented by the large fish symbols. The 200DX can be
set to alarm on only large and medium fish or set to alarm
on all fish.

USING THE 200DX
MENU FUNCTIONS
Once the Fish Alarm is enabled, the 200DX emits an
audible beep when the selected size fish symbol
appears on-screen. The sound is slightly different for
each of the three fish symbol sizes, so with practice,
it is possible to distinguish the size of the detected fish without looking at the unit.
Triplog. Triplog provides a running log or information based
on input from the Temp/Speed sensor.
Since Triplog requires information from the
Temp/Speed sensor to operate, if this sensor is not
detected by the 200DX, the Triplog menu will not appear
as an option.
Triplog provides seven pieces of information: the current
digital depth, water surface temperature, current boat
speed, the distance traveled since the 200DX was powered
up or reset, the average speed, the total time elapsed since
power-up or reset, and the input voltage from your boats
electrical system.
The time, speed and distance calculations are useful for
tracking your progress on a trip. The input voltage is useful
for determining the condition of the charging system of the
boat. When used in a portable application or whenever the
200DX is operated from a battery source, the voltage
number can he used to determine battery life. The 200DX
will operate at voltages from 10 to 20 VDC. Voltages in
excess of 20 or less than in 10 VDC cause the unit to power
off.

USING THE 200DX
MENU FUNCTIONS
Options. The Options Menu is a series of linked menu functions
used initially to set your preferences. Once your preferences are
selected it is unlikely these functions need to be accessed during
the normal operation of the product.
The Options menu works differently than other menu functions in that all of the options
must be cycled through in order to return to normal operation. There are six Option
menus: Units, Fish ID, Numeral size, Bottom Black, Diagnostic, and Reset.
Units Speed. The Units Speed function allows the user to elect
the units or measurement for the speed readout. Both MPH or
statute miles per hour and KTS or nautical miles per hour are
available. The 200DX remembers this selection even when the
unit is powered off.
Units Depth/Speed. Only available on metric versions, the
Units Depth/Speed function allows the user to select the units of
measurement for the depth and speed readout. MT/KPH
(meters/kilometers per hour), MT/KTS (meters/nautical miles per
hour), FEET/MPH (feet/statute miles per hour) and FEET/KTS
(feet/nautical miles per hour), are available. The 200DX
remembers this selection even when the unit is powered off.

USING THE 200DX
MENU FUNCTIONS
Fish ID. There are three selections available: Off, ID+ ON, and
Adjust. The factory setting is ID+ On. With Fish ID Off, sonar
returns are displayed as “raw” information. There is no
interpretation made by the unit. Selecting ID Off also disables the
fish alarm.
ID+ On enables the 200DX to interpret the raw sonar data, and
using a variety of techniques, depict appropriate target returns as
one of three different size fish symbols. Further identification
shows whether the fish is in the wide or narrow beam. The 200DX
also displays the depth beneath the surface with the corresponding
fish symbol.
Selecting Adjust and making incremental changes enhances the
fishfinder’s ability to identify sonar returns as fish symbols.
Increasing the value to a number greater than zero shows more
fish symbols on-screen. In this case smaller sonar returns will be
depicted as fish symbols. This is useful for identifying many smaller
sonar returns (suck as baitfish) as fish symbols.
Decreasing the value to a number less than zero shows fewer fish symbols on-screen.
In this case smaller sonar returns are disregarded. This is useful for eliminating many
small sonar returns when seeking larger species of fish.
The 200DX remembers this selection even when the unit is powered off.
Numeral Size. Two options are available: Big and Small. The
factory setting is Big. With this setting, the digital depth and
speed and temp numerals are drawn large enough to be read
from across the boat. The big numerals occupy space on the
display that could be used for the graphics area. Hence the
small numerals option. With small numerals selected a greater
amount of the display area is available for the graphic view. This
effectively increases the display resolution of the unit.
Numeral Size settings are remembered when powered off.

MENU FUNCTIONS
Bottom Black. There are two selections available: Off and
On. The factory setting is Off. With this setting the 2OODX
displays the bottom using Structure ID. This allows you to
determine the texture and relative hardness of the bottom.
Selecting Bottom Black ON causes the unit to blacken in
the display below the bottom. This gives the user easiest
recognition of the bottom location even from a great
distance.
The 200DX remembers the Bottom Black setting when
powered off.
Diagnostic. Two options are available: Hide and Show.
The factory setting is Hide. Selecting Show brings up the
Diagnostic screen. See the Using Diagnostic section for
more information.

ADVANCED FEATURES
USING DIAGNOSTIC
Reset. With the many User Options available to customize the 200DX, it is easy to
configure the unit in such a way that it is detrimental to a particular use.
By using the Reset function, all variable or user-controlled features of the
200DX are returned
to the factory settings.
The Reset function is an important first step in troubleshooting problems to assure that
a user selected setting is not the cause for the perceived problem.
USING THE DIAGNOSTIC FEATURE
The 200DX contains a powerful diagnostic tool that can aid in
determining the cause of a problem.
To use the Diagnostic feature, select the Diagnostic feature
on the start-up menu on the initial screen. Diagnostic can also
be accessed through the Options menu.
Self Test. Initially the 200DX will perform a self-test. This test
confirms the operation of all internal circuitry. At the
conclusion of the test one of two messages will appear.
“Passed” indicates the internal test discovered no failures,
“Failed” indicates a significant internal problem was discovered and the unit requires
factory service. A code number appears that tells repair personnel where the problem
is.
Transducer Connection. The first connection tested is Transducer input. If a
transducer is detected, the message “connected" appears. If a series of dashed lines is
shown no transducer is connected or there is a problem with the transducer or cable.
If you are using multiple transducers, switch between transducers to confirm the
connections for each.

ADVANCED FEATURES
USING DIAGNOSTIC
Boat Speed/Water Temperature Connection. Other
connections tested include the boat speed and surface water
temperature sensors. These accessory sensors can be
purchased independently or together as a single sensor (see
the Humminbird Accessories catalog). If the sensors are
connected and working properly a “connected” message
appears.
The speed input feature only works when the boat is in
motion as the paddle wheel or the speed sensor must rotate
to be detected.
Voltage Input. Another connection tested is the voltage input, and is especially helpful
in diagnosing input voltage problems. The current input voltage is displayed. If voltage
fluctuations or power supply in excess of 20 \/DC or less than 10 VDC is suspected, use
the diagnostic screen to confirm input voltage. Often small outboard motors do not
effectively regulate voltage when operated at high engine speeds.
Use Diagnostic while running the boat at high speeds to show the voltage gain. Also, if
you are using the 200DX in portable configuration or from the trolling motor battery
Diagnostic can be used to evaluate the health of the battery by showing the current
voltage.
Total Time. The total time category indicates the total time the unit has been in use
since shipped from the factory. It is normal for some hours to appear in the total time
when the unit is new due to factory testing. While this is often of interest to the user it is
primarily a diagnostic tool for the repair technician should the unit need service.

MAINTENANCE
Your Humminbird fishfinder is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your Humminbird
continues to deliver top performance.
·
·
·
If the 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.
Chemicals in the solution may cause cracking in the lens of the unit.
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.
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 liquid detergent. 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 when returned to the water. Small air bubbles can climb to the
surface of the transducer and interfere with proper operation. These bubbles
dissipate with time, or you can wipe the face of the transducer with your fingers after
the transducer is in the water.
Never leave the fishfinder in a closed car or trunk - the extremely high temperatures
generated in hot weather can damage the electronics.

MAINTENANCE AND WARRANTY
TROUBLESHOOTING
TROUBLESHOOTING
Do not attempt to repair the fishfinder yourself. There are no user serviceable parts
inside, and special tools and techniques are required for reassembly to ensure the
waterproof integrity of the housing. Repairs should be performed only by authorized
Humminbird technicians.
Many requests for repair received by Humminbird involve units that do not actually reed
repair. These units are returned “no problem found.” If you have a problem with your
Humminbird, use the following troubleshooting guide before calling Customer Support
or sending your unit in for repair. Your Humminbird fishfinder contains several tools that
can aid in determining if there is a problem and how to isolate and repair the problem in
many cases.
1. Nothing happens when I turn the unit on.
Check the power cable connection at both ends. Be sure the cable is connected
correctly to a reliable power source - red lead to positive, black lead to negative or
ground. Ensure the power available at the mount is between 10 and 20 VDC. If the unit
is wired through a fuse panel, ensure the panel is powered. Often accessory fuse
panels are controlled by a separate switch or the ignition switch. Also, often a fuse can
appear to be good when in fact it is not. Check the fuse with a tester or replace it with a
fuse known to be good.
Check the power connection to the unit. It is possible to force the power cable connector
into the cable holder incorrectly. If the connector is reversed, the unit will not work.
Examine the contacts on the back of the unit to ensure there is no corrosion. Finally,
ensure the unit is firmly seated on the mount. The electrical contacts are not made until
the unit is fully seated.
Ensure the metal cable retainer is properly installed in the mount. If not, the power
connected may push out when the unit is put on the mount.
2. There is no transducer detected.
Most Humminbird fishfinders have the ability to detect and identify that a transducer is
connected. If at power up, a message indicates "transducer not connected,” only
simulator operation is possible. First, ensure that an appropriate transducer connector is
positioned correctly in the connector holder, and that the unit is fully seated on the
mount. Your Humminbird fishfinder will work only with an appropriate transducer; check
the accessory guide for compatibility.

TROUBLESHOOTING
Second, inspect the transducer cable from end to end for breaks, kinks, or cuts in the
outer casing of the cable. Also ensure the transducer is fully submerged in water. If the
transducer is connected to the unit through a switch, temporarily connect it directly to
the unit and try again. If none of these items identifies an obvious problem, the
transducer itself is probably the problem. Be sure to include the transducer if returning
the unit for repair.
3. There is no bottom reading visible on the display.
There are a number of possible causes for this condition. If the loss of bottom
information occurs only at high boat speeds, the transducer needs adjusting. If the
digital depth readout is working but there is no bottom visible on-screen, it is possible
the depth range has been adjusted manually to a range lower than what is needed to
display the bottom. Also, in very deep water, it may be necessary to manually increase
the sensitivity setting to maintain a graphic depiction of the bottom.
If you are using a transducer switch to connect two transducers to the unit, ensure the
switch is in the correct position to connect a transducer that is in water. (If a trolling
motor transducer is selected and the trolling motor is out of water, no sonar information
appears.)
It none of the above solve the problem, inspect the transducer cable from end to end for
breaks, kinks, or cuts in the outer casing of the cable. If the transducer is connected to
the unit through a switch, temporarily connect it directly to the unit and try again. If none
of these items identifies an obvious problem, the transducer itself may be the problem.
Be sure to include the transducer if returning the unit for repair.
4. When in very shallow water, I get gaps in the bottom reading and inconsistent
digital depth indication.
Your Humminbird fishfinder will work reliably in water 2’ (.6m) or deeper. The depth is
measured from the transducer, not necessarily from the surface.

MAINTENANCE AND WARRANTY
TROUBLESHOOTING
5. The unit comes on before I press POWER, and won't turn off.
Check the transducer cable. If the outer jacket of the cable has been cut and the cable
is in contact with bare metal, you need to repair the cut with electrical tape. If there is no
problem with the cable, disconnect the transducer from the unit and see if the problem
is corrected, to confirm the source of the problem.
6. I get gaps in the reading at high speeds.
Your transducer needs adjusting. If the transducer is transom-mounted, there are two
adjustments available to you - height and running angle. Make small adjustments and
run the boat at high speeds to determine the effect. It may take several tries to optimize
high speed operation. This can also be a result of air or turbulence in the transducer
location caused by rivets, ribs, etc.
7. My unit loses power at high speeds.
Most Humminbird fishfinders have over-voltage protection that turns the unit off when
input voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the
power output of the engine's alternator and can produce voltage in excess of 20 volts
when running at high RPMs. Your fishfinder displays input voltage in the Diagnostic
screen. Use this readout to determine if the voltage exceeds 20 VDC.
8. The screen begins to fadeout. Images are not as sharp as normal.
Check the input voltage using Diagnostic. The fishfinder will not operate on input
voltages below 10 VDC.
9. The display shows many black dots at high speeds and high sensitivity
settings.
You are seeing noise or interference caused by one of several sources. Noise can be
caused by other electronic devices. Turn off any nearby electronics and see if the
problem goes away. Noise can also be caused by the engine. If engine noise is causing
the interference, the problem will intensify at higher RPMs. Increase the engine speed
with the boat stationary to isolate this cause. Propeller cavitation can appear as noise
on-screen. If the transducer is mounted too close to the propeller, the turbulence
generated can interfere with the sonar signal. Ensure that the transducer is mounted at
least 15" (38cm) from the prop.
