ACCESSORIES
Techsonic offers a wide assortment of accessories that complement and
expand the capability of your new 160. These accessories are designed
with the same high standards and are backed by the same one-year
warranty. All sonar accessories are available through your full-service
dealer or factory direct through our number listed in the Customer Support
section.
INSTALLATION OVERVIEW
All 160 Series consists of three primary components to install: the control
head, the transducer and the speed/temp sensor.
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 gimbal mounting system that tilts and swivels providing
flexibility for viewing from different locations on the boat. In addition, the
160 can be mounted in the boat console.
3
INSTALLATION PREPARATION
INSTALLATION OVERVIEW
The speed/temperature sensor takes readings from the water at the
surface. It should be installed in contact with the surface of the water in an
area that has smooth water flow - usually on the transom of the boat.
Refer to the speed/temperature installation sheet included.
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 water flow - 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.
Determining How to Mount the
Transducer
The 160 includes a model TZ160H
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.
Transom Mounted Transducer
Inside the Hull Mounted Transducer
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 to be drilled into the boat and thr ough
experimentation, high-speed operation comparable to transom mounting can be
achieved. Two part, slow cure epoxy is required to glue the transducer in place.
ALTERNATE TRANSDUCERS AND MOUNTING METHODS
The 160 comes with everything necessary for installation and operation on
most boats. However, there are several situations which may requir e a differ ent
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.
Trolling Motor Mounting
The standard high-speed transducer can also be adapted to mount on most
trolling motors using part number AD-STM-7. This accessory includes a bracket
and hose clamp that allows mounting the transducer to the body of most
trolling motors.
BEGINNING INSTALLATION
Now that you have determined the transducer mounting method, you can
begin installation of the 160. The fold out installation guide included provides
detailed step by step instructions for installation of the control head, transducer
and speed/temp sensor. For transom mount transducer installations, you will
need the mounting template at the front of this manual.

160 PERFORMANCE
In addition to the parts included you need the following for installation and operation:
• A powered hand drill and various drill bits
• Phillips and flat-head screw drivers
• A ruler or measuring tape
• Pen or pencil
• 12 volt power source (your boat’s battery)
• Silicone sealant (for sealing drilled holes)
• 2-part, slow-cure epoxy (for inside the hull transducer installations)
USING THE 160
160 Performance
The 160 Series repr esents a new way of thinking about fishing electronics.
Combining state of the art electronics and paper chart recorder sonar
performance, it offers the best of the present and the past. Minimal, easy
to understand knob controls provide access to the most important featur es.
The 160 eliminates confusion created by too many buttons and menus.
High technology, high performance, with "back to basics" operation
makes the 160 the ideal choice of the serious angler.
The 160 uses sonar to locate and define underwater objects. Sonar
technology is based on sound waves sent into the water in a controlled
"beam" from the transducer. Objects within this beam reflect the sonar
signal back. The 160 very accurately measures the distance to these objects
based on the time it takes for the sonar to return. Each object (bottom, fish
or structure) reflects the sonar uniquely, providing information about its
makeup. The 160 draws this returned information on the display.
The 160 operates in a wide variety of water conditions, from 2’ to 600’.
Actual depth capability depends on many factors such as bottom hardness,
water conditions, and transducer installation. All sonar units typically read
to deeper depths in fresh water than saltwater.

USING THE 160
SIMULATOR AND FEATURE MEMORY
POWERING UP THE 160
After installation, turn the 160 on by momentarily pressing the Gain knob.
An audible chirp sounds as the unit turns on. If the unit detects that the
transducer is connected and is in water, the 160 begins to show sonar
information on the display. If the transducer is not detected, the unit starts
up in simulator mode.
To power the unit off at any time, press and hold the Gain knob for several
seconds until the 160 turns off.
Simulator and Feature Memory
The 160contains a simulator that allows you to use the unit as though you are on the
water. The Simulator is an invaluable aid to learning the features and functions of the
160. All controls are operational and settings can be changed to experiment with
various features. When operating in Simulator an indicator appears at the bottom left
of the display.
There are two ways to start the simulator. The method to use depends on whether a
transducer is connected:
If the 160is powered on with no transducer connected, it starts up in simulator mode.
No other steps are needed. In this mode the 160 does not remember any setting
changes that are made.
If the 160 is powered on with the transducer connected, the Simulator must be
manually turned on.
To manually turn the simulator on:
1. Press the Control Panel knob to display the
list of options.
2. Rotate the Control Panel knob to scroll
through the list until Simulator is visible and is
highlighted on the display.
3. Turn the Range knob to turn Simulator from
OFF to ON.
4. Press the Control Panel knob to clear the scr een.
When operating with the Simulator on and the transducer connected
changes made to Chart Speed, RTS Window, Surface Clutter, Contrast,
White Line, (language in international models,) and the Units Control
Panels are permanently remember ed. When a transducer is not connected,
changes are not remembered.
CONTROL FUNCTIONS
Three knobs on the 160 control all user settings: Gain,
Control Panel and Range.
G
AIN KNOB
The GAIN knob controls the gain (sometimes called
sensitivity) of the sonar receiver. G
AIN also powers the unit
on or off. When the 160 is off, press G
AIN to turn the unit
on. Press and hold G
AIN to turn the unit off.
Increasing the gain shows faint sonar returns from small bait fish and
suspended debris in the water, however the
display may become too cluttered in some
water conditions. Increased gain is also
beneficial at deeper depths to maintain a
good bottom image and adequately show
sonar returns from deep objects. Decreasing
the gain eliminates the clutter from the
display, however if adjusted too low may not
show many faint sonar returns that could be
fish.
Turn the G
AIN knob clockwise to increase the
gain; turn counterclockwise to decrease the
gain. As you turn the knob, only new sonar
information being graphed shows the affect
of the gain change.

The RANGE±knob adjusts the depth
ranges used on the display. The
Range± knob has slightly different
capabilities in each mode of
operation. See Modes of Operation
for specific information. In all cases
turning the knob clockwise increases
the range, while turning it
counterclockwise decreases the
range. Turning the knob slowly
increases the adjustment in small
increments, while turning it quickly
makes large changes to the
adjustment.
THE 160 DISPLAY
The 160 uses a high resolution LCD display to show sonar information,
digital depth, temperature, speed and other readouts.
A digital depth readout ranging from 2 to 600 feet is always displayed in
the upper left corner of the LCD. When the speed/temp accessory is
connected, additional digital readouts are shown below the depth. A
voltage readout appears in the bottom left when the input voltage to the
160 is less than 10 volts or greater than 16 volts.

A depth range scale appears close to the right side of the LCD display. This
scale indicates the distance from the surface of the water to a depth range
sufficient to show the bottom. For example, in 18 feet of water a 20 foot
depth range is selected. The depth range scale can be controlled
automatically or manually depending on the mode of operation. In
automatic and bottom lock mode, the 160 selects the depth range. In
manual mode the depth range is selected by the user.
The sonar returns received by the 160 are displayed along the depth range
scale in a Real Time Sonar (RTS) Window and Chart Window. The RTS
Window displays new sonar information within the transducer cone in an
expanded easy to see format; the Chart Window logs old RTS Window
information to show a contour view of the bottom and structure.
Real Time Sonar Window
The Real Time Sonar (RTS) window shows
instantaneous sonar returns from the
bottom, structure and fish that are within the
transducer beam. The RTS window updates
with new sonar information much more
quickly than the chart window - up to 20
times per second in shallow water. The RTS
window responds to quickly changing depths
similar to a flasher. Interpreting the RTS
information requires some skill; however
comparing the RTS presentation with the
information on the chart window makes it
easy to understand.
The RTS window plots the depth and
intensity of a sonar return. Sonar intensity is indicated by the length of the
horizontal lines, while depth is indicated by the vertical placement of the
lines next to the depth range scale. The intensity of the sonar return is
divided into 4 levels of grayscale. The most intense returns are shown in
black; less intense sonar returns are shown in progressively lighter shades
of gray.
The combination of the length of the lines and the gray scale level helps to
identify the bottom composition and structure. The bottom is the largest

grouping of black horizontal lines, typically
having gray lines underneath. A harder
bottom shows less gray below; a soft
bottom shows more gray below. Structure
appears above the bottom as a cluster of
lines with varying lengths and gray shades.
Fish appear as smaller groupings of sonar
returns between the bottom and surface.
Often, large fish within structure will
show as a strong return within a grouping
of smaller returns. When the boat is
stationary or drifting very slowly, the RTS
window can show the movement of the fish through the transducer beam.
Moving fish appear as smaller groups of lines progressively become larger
lines, or vice versa. A grouping of lines moving vertically indicates a fish
changing depth.
The width of the RTS window can be adjusted to your preference.
Selecting a wider RTS window shows greater differences between
the strength of the sonar returns; however it reduces the amount
of history on the display. See C
ONTROL PANELs for details of
adjusting the RTS Window.
The Chart Window
The chart window creates a historical log
of sonar returns from the RTS window. As
the boat moves, variations in the depth
and sonar return change and are charted
to form an image of the bottom contour.
The most recent sonar returns are charted
on the right side of the window; as new
information is received the older
information is moved across the display.
The chart window also indicates the
composition of the bottom. A hard bottom
such as compacted sediment or flat rock
appears as a dark, thin line across the

display. Soft bottoms such as
mud or sand appear as a thicker
line having a transition from dark
to light grays. Bottoms made up
of many rocks have a broken,
random appearance.
Bottoms having a large degree
of slope also present a unique
picture. These generally have a
thicker black band representing
the bottom directly under the
boat. Equal areas of gray above and below the black band represent sonar
returns from around the boat.
A second sonar return may be visible if the appropriate depth range is
selected. This appears as a depth contour below the main bottom contour,
at twice the depth. The second return occurs when the sonar signal bounces
between the bottom and surface of the water and back again. Some anglers
use the appearance of the second return to determine bottom hardness.
With a lower gain setting the second return will be more faint, except in
areas with hard bottom. The 160 has a unique depth range feature which
permits the second return to be visible in any depth range. See Modes of
Operation for details.
The 160displays structure such as submerged grass, brush, trees and wrecks
on the bottom. Structure can be distinguished by comparing the area just
above and below the main bottom return. Usually structure shows as areas
of dark to light gray on top of a dark bottom contour. The appearance of
structure is greatly af fected by boat speed and dir ection; to r epeat the same
image it is often necessary to travel the same speed and direction over the
location where the structure was originally located.
The 160 is also capable of showing layers of water having different
temperatures. These temperature dif ferences, called thermoclines, appear at
different depths, depending on current conditions. A thermocline typically
appears as a continuous band of many gray levels moving across the display
at the same depth. Thermoclines always appear above the bottom.
Schools of bait fish as well as individual fish are clearly visible on the 160
display. Bait fish appear as "clouds" having different shapes and sizes

depending on the number of fish
and boat speed. Individual fish
appear as smaller black and gray
lines often appearing as a "fish
arch." A fish arch forms as the fish
moves through the sonar beam.
Due to the transducer beam angle
the distance to the fish decreases
as it moves into the beam, and
then increases as it moves out.
When the chart window graphs
this distance change, an arch appears. Boat
speed, the Chart Speed setting and
movement of the fish greatly affect the
shape of the arch. When moving slowly, a
fish creates an elongated arch. With the
boat moving fast the arch appears shorter.
A partial arch forms when the fish does not
move through the entire cone angle.
It is important to remember that sonar cannot distinguish between a fish
and some other object suspended in the water. Regardless of the object the
sonar detects, each has the possibility of being drawn as an arch.
MODES OF OPERATION
Three modes of operation control the method the 160 uses to track the
bottom and select depth ranges. The Mode
is selected by changing the C
ONTROL PANEL
setting to AUTO, MANUAL, or BTM LOCK
(Bottom Lock).
A
UTOMATIC MODE
Automatic Mode follows the bottom contour, changing depth ranges as
needed to keep the most recent sonar returns visible on the display.
Automatic Mode keeps the bottom visible at all times, showing sonar
returns from the surface to the bottom and just beyond. This is useful when
traveling across the water in areas where the depth constantly changes
requiring frequent range changes.

The 160 selects the depth range best
suited to keep recent sonar returns
visible, however, the depth range can be
adjusted to optimize the display for
viewing the second return. The display
can also be optimized for maximum
display resolution, making it possible to
distinguish fish very close together or
close to the bottom.
When the image of the bottom does not
appear close to the bottom of the LCD
display, the 160 is not fully optimizing
the display to show sonar targets, such as
fish, that are very close together. To
enhance the 160’s ability to separate sonar targets and optimize the display
for maximum resolution follow these steps.
1. Make sure the 160 is operating in Automatic Mode.
2. Push the Range± Knob. An adjustment indicator appears at the lower
right corner of the chart window.
3. Turn the Range± Knob counterclockwise until the image of bottom is
close to the bottom of the LCD display but still shows the area you are
interested in.
Note: As the depth of the water increases, the 160 changes the
depth range to keep the bottom on-screen. The 160 uses a depth
range to keep the bottom contour close to the bottom of the
display.
To return the depth range to normal viewing,
turn the unit ‘Off and back On again’. This is
the only way to ‘reset’ the depth range to
normal viewing.
To optimize the depth range for viewing the
second return follow these steps.
1. Make sure the 160 is operating in
Automatic.

2. Push the Range± Knob. An adjustment
indicator appears at the lower right corner
of the chart window.
3. Turn the Range± Knob clockwise until
the second return is visible on the display.
4. To return the depth range to normal
viewing, rotate the depth range
counterclockwise until the depth range
stops updating.
Note: The second return does not
appear at many of the deeper depth
ranges. The appearance of the second return depends on depth of
the water, water conditions, bottom hardness and the gain
setting.
The 160 operates with this offset depth range until it is returned to the
original settings or the unit is turned off.
B
OTTOM LOCK ZOOM MODE
Bottom Lock Mode tracks the bottom similar to
Automatic Mode, however the display shows a full range view on right and
a zoomed window on the left. The zoomed window provides added display
resolution for separating sonar returns that are very close together, such as
fish suspended close to the bottom.
As the depth changes the 160 automatically keeps the bottom visible in the
zoomed window and the full range view. In the full range view, horizontal
zoom preview bars define the area of bottom being enlarged. The default
setting varies based on the depth range. However, this setting can be
changed to show more area around the bottom, or the bottom in greater
detail.
To change the area of the bottom being zoomed, follow these steps:
1. Make sure the 160 is operating in Bottom Lock mode.
2. Push the Range± Knob. An adjustment indicator appears by the lower
zoom preview bar indicating this is the selected depth limit for adjustment.

3. Rotate the Range Knob to adjust the
zoom preview bar. Moving the zoom
preview bars closer together increases the
display resolution in the zoomed window;
moving them further apart decreases display
resolution, but allows more area around the
bottom to be viewed.
The indicators disappear after several seconds with no adjustment. The 160
continues to follow the bottom using the new range. Any change made to
the zoom preview bars is remembered until the 160 is powered off.
M
ANUAL MODE
Manual Mode turns off the automatic bottom
tracking leaving control of the depth range to the
user. Both the upper and lower depth ranges can be adjusted to show the
bottom in great detail or any other desired depth. When first switched to
manual mode, the 160 defaults to the current automatic depth range;
however, after the manual depth ranges have been set, the 160 uses the
new settings until it is powered off.
Manual Mode works best in areas of relatively flat bottom or if you are
trolling slowly. It is also ideal for displaying a small area of the overall depth
range in great detail if you are looking for fish at a specific depth.
To manually adjust the depth ranges follow these steps:
1. Make sure the 160 is operating in Manual Mode.
2. Push the Range Knob. An adjustment indicator appears at the location
of the lower Depth Range indicating it is ready for adjustment.

RTS WINDOW selects the width of the window
dedicated to Real Time Sonar. Selecting Narrow
decreases the width of the RTS window leaving
more space for the chart window, however some
sonar returns will not be visible. Selecting Wide makes the RTS window
wider and shows more of the sonar intensity information, however less
space on the LCD is available for sonar history. Selecting Off turns off the
RTS window and the entire LCD shows sonar history.
Note: When the RTS window is adjusted to Wide, no grayscale
information is shown.

factory setting is Narrow.
S
URFACE CLUTTER eliminates most sonar returns
near the water surface caused by trapped air,
boat wakes and temperature inversions. Most
surface clutter appears on the display because the
strongest sonar return comes from the shallowest objects. The 160 uses a
sophisticated feature called TVG (Time Variable Gain) to overcome surface
clutter and counteract the affect of depth on sonar return strength. The
level 1 setting is optimal for making sonar information from all depths
appear the same. However, many users prefer to see more surface clutter
than this setting shows. Selecting a higher number shows more surface
clutter, but sonar returns nearest the surface will appear more intense than
they actually are.
The Surface Clutter setting is retained in memory when the 160 is turned
off. The factory setting is 4.

HITE LINE
activates and adjusts a feature which
changes how the 160 draws the bottom contour
and structure, as well as show fainter sonar
returns more clearly. When a White Line setting
of 1 to 8 is selected, a light gray band highlights the strongest sonar returns
within the sonar image and makes a distinctive outline along the bottom
contour, structure and fish. Selecting a larger numeric setting increases the
width of the band and makes fainter sonar returns more noticeable;
however the 160’s ability to show subtle differences in bottom composition

and structure is reduced. Selecting a smaller
numeric setting narrows the band, and
shows greater variation in bottom
composition. Selecting "OFF" turns the
White Line feature off.
Note: The White Line setting is
retained in memory when the 160 is
turned off. The factory setting is

DEPTH A
LARM
activates a shallow water depth
alarm. The alarm will sound when the digital
depth becomes equal to or less than the setting.
The tone sounds at a rapid rate for several
seconds and then sounds intermittently until the boat moves to deeper
water. The Depth Alarm can be muted by pressing the C
ONTROL PANEL
knob; once muted the alarm will not sound again until the boat moves
to water greater than the Depth Alarm setting. Remember, depth is
measured from the transducer, not the surface of the water.
The Depth Alarm setting is not retained in memory when the 160 is turned off.
S
IMULATOR allows the 160 to operate in simulated sonar mode. This is
useful for learning the features and functionality
of the 160 when not on the water. When
operating with the simulator on and without a
transducer connected the 160 does not
remember any changes to settings.
The Simulator setting is not retained in memory when the 160 is turned off.

MAINTENANCE
Your 160 is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
160 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 cling 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 160 in a closed car or trunk—the extremely high
temperatures generated in hot weather can damage the electronics.
TROUBLESHOOTING
Do not attempt to repair the 160 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 Techsonic technicians.
Many requests for repair received by Techsonic involve units that do not
actually need repair. These units are returned "no problem found." If you
have a problem with your 160, use the following troubleshooting guide
before calling Customer Support or sending your unit in for repair. The 160
contains several tools that can aid in determining if there is a problem and
how to isolate and repair the problem in many cases.
MAINTENANCE AND WARRANTY
MAINTENANCE/TROUBLESHOOTING
22
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 160. It is possible to force the power
cable connector into the collector plug 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.
Ensure the cables are properly installed into the collector plug and the
collector plug is properly seated into the 160.
2. The Unit Starts up in simulator mode.
The 160 has the ability to detect that a transducer is connected. If, at power up,
a transducer is not connected, the unit starts up in simulator mode.
Ensure that an appropriate transducer connector is used and the connector
is positioned correctly in the collector plug. Also be sure that the collector
plug is fully seated into the unit. 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.
To manually override the simulator, select the Simulator C
ONTROL PANEL and
turn to off. See C
ONTROL PANELs for more information.
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
22

TROUBLESHOOTING

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 G
AIN setting to
maintain a graphic depiction of the bottom.
If you are using a transducer switch to connect two transducers to the 160,
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.)
If 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.
The 160 will work reliably in water 2' (.6m) or deeper. The depth is
measured from the transducer, not necessarily from the surface.
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 corr ected, 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.
Your 160 has over-voltage protection that turns the unit off when input
voltage exceeds 20 VDC. Some outboard motors do not effectively r egulate
the power output of the engine’s alternator and can produce voltage in
excess of 20 volts when running at high RPMs. The 160 displays input
voltage in the lower left corner of the display when it exceeds 15 VDC. Use
this readout to determine if the voltage exceeds 20 VDC.
8. The screen begins to fade out. Images are not as sharp as normal.
Check the input voltage. The 160 will display the current voltage on-scr een
if it is greater than 16 or less than 10 VDC. The voltage readout will appear
in the bottom left corner of the screen.
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 onscreen. 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.
10. The screen does not display a full fish arch.
Check the running angle of the transducer. If the running angle is too
great, a full fish arch may not appear. Reduce the running angle of the
transducer. Several incremental adjustments may be necessary.
