NAVMAN  
 
1 Introduction  
This manual also explains how to operate the  
FISH 4500/4600 effectively and provides trou-  
bleshooting information and performance tips.  
Congratulations on choosing a Navman fish-  
finder. For maximum benefit, please read this  
manual carefully before installation and use.  
Important  
This manual describes how to install and set up  
the FISH 4500/4600 and the associated dual-  
frequency transom transducer. (If a through  
hull transducer is used, refer to the Installation  
Instructions supplied with that transducer.)  
It is vital to the performance of the fishfinder  
that the transducer is installed in the best  
location. Please follow the installation  
instructions very carefully.  
1-1 Benefits of the FISH 4500/4600  
The FISH 4500/4600 is a high quality, dual-  
frequency sonar fishfinder that is supplied with  
a dual-frequency transducer. It uses TFT (Thin  
Film Transistor) technology to provide a color  
display for easy daylight viewing that can be  
dimmed for night fishing. The bracket mounting  
option also allows the fishfinder to be tilted and  
swivelled for optimum viewing.  
The colors on the sonar displays are customiz-  
able, with a choice of four 16 color palettes and  
one 8 color palette. The colors represent differ-  
ent signal strengths, making the sonar displays  
easy to interpret.  
The Navman fishfinder can also assist with  
navigation by providing depth information to help  
identify the depth contours marked on charts.  
The FISH 4500/4600 is particularly suited to  
work with the TRACKER 5500/5600 - Navman’s  
color display GPS chartplotter with worldwide  
coverage.  
The two instruments can be connected together  
using either NavBus or NMEA, so they can  
share data.  
IMPORTANT NOTE ON USE. While any  
fishfinder can be used as an aid to navigation,  
accuracy can be limited by many factors, includ-  
ing the location of the transducer. It is the user’s  
responsibility to ensure the Navman fishfinder is  
installed and used correctly.  
With the optional fuel kit, the FISH 4500/4600  
also becomes a sophisticated and easy-to-use  
fuel computer.  
All of the Navman 4000 Series fishfinders use  
new proprietary SBN-II Technology for sonar  
processing to improve Signal enhancement,  
Bottom recognition and Noise rejection.  
SBN-II Technology uses digital adaptive filter  
algorithms to enhance all returned signals.At the  
same time, SBN-II Technology uses active noise  
control to reject interference, which can often be  
mistaken by fishfinders for true returns.  
Using SBN-II Technology, the Navman fishfinder  
analyses the reflections from each pulse, filters  
false returns and displays what is in the water  
under the boat. See section 4-1 Interpreting the  
display, for more information.  
The dual frequency capability enables the  
FISH 4500/4600 to operate and display:  
At a high frequency of 200 kHz.  
At a low frequency of 50 kHz.  
Both frequencies side-by-side on a split dis-  
play.  
Both frequencies combined together into a  
single display.  
This capability, combined with a variable power  
output of up to 600 W RMS, ensures that the  
FISH 4500/4600 operates effectively in shallow  
and deep water.  
The FISH 4500/4600 can detect the bottom to a  
depth of 2000 feet (600 metres) depending on  
the clarity of the water, the ultrasonic frequency  
chosen and the type of transducer used.  
The Navman fishfinder can be used to find fish,  
to locate features on the bottom such as reefs  
or wrecks and to help recognize favourite fishing  
spots from the bottom profile.

1-2 How the FISH 4500/4600 works  
The FISH 4500/4600 has two parts:  
- the transducer attached to the hull  
- the display unit.  
The transducer generates an ultrasonic pulse  
(sound that is above the hearing range of the  
human ear), which travels down towards the  
bottom at a speed of about 4800 ft/sec (1463 m/  
sec), spreading out into a cone shape.  
When the pulse meets an object, such as a  
fish or the bottom, it is partly reflected back  
up towards the boat as an echo. The depth  
of the object or bottom is calculated by the  
FISH 4500/4600 by measuring the time taken  
between sending a pulse and receiving the  
echo. When an echo has been returned, the  
next pulse is sent.  
The FISH 4500/4600 converts each echo into  
an electronic signal, displayed as a vertical line  
of pixels. The most recent echo appears on the  
extreme right of the display, with the older echoes  
being scrolled towards the left, eventually disap-  
pearing off the display.  
The scroll speed depends upon the water depth  
and scroll speed setting. See section 3-2 Setup  
> Sonar and section 4-1 Interpreting the display,  
for more information.  
The appearance of echoes displayed are af-  
fected by:  
the fishfinder settings (frequency selected,  
range and gain settings)  
echoes (different fish types, different bot-  
tom types, wrecks and seaweed)  
noise (water clarity and bubbles).  
See section 4-1 Interpreting the display, for more  
information.

Set remaining  
Flow filter  
Most engines do not draw fuel from the tank at a  
steady rate. To give a stable fuel flow reading, the  
fishfinder calculates the flow value(s) by taking  
several measurements and averaging them. Use  
the Flow filter to set the period over which the fuel  
flow is averaged.  
Before doing a partial refill of the tank or remov-  
ing fuel manually from the tank (for example, by  
siphoning it off):  
1. Note the Remainingreading on the  
Fuel display.  
2. Note how much fuel is added or removed.  
3. Calculate how much fuel is now in the tank.  
4. Select Set remainingand update  
the reading.  
It is essential to do this whenever some fuel  
is added or removed. Otherwise, the read-  
ing on the Fuel display (see section 5-6 Fuel  
Display) and the Low Fuel Alarm (see section  
3-5 Setup > Alarms) are meaningless.  
For twin engine installations, the fuel flow for each  
engine must be adjusted separately.  
TheFlowfiltercanbesetfrom0to30seconds. Use  
thelowestvaluewhichgivesastableflow. Usuallya  
valueof5to10secondswillgiveasatisfactoryresult  
for two-stroke carburettor engines. Fuel injected or  
four-stroke engines may require a larger value.  
This setting affects the Fuel flow and Fuel

Calibration may be required because different hull  
shapes have different flow characteristics.  
Use the cursor keys to display the temperature  
readout box, then increase or decrease the value  
to match the measured temperature.The tempera-  
ture can be set from 32° to 99.9°F (0° to 37.7°C)  
with a resolution of 0.1° unit.  
Obtain an accurate measurement of the boat’s  
speed from a GPS receiver; or by following another  
boat travelling at a known speed; or by making a  
timed run over a known distance.  
Note: for accurate calibration:  
The speed from a GPS receiver should be  
greater than 5 knots.  
To change the units between °F (Fahrenheit) or °C  
(Celsius), see section 3-6 Setup > Units.  
The speed from another paddlewheel trans-  
Temp filter  
ducer should be between 5 and 20 knots.  
Increase this setting to stabilise an erratic tem-  
perature reading. Decrease to improve reading  
responsiveness. The temperature filter can be  
set from 0 to 30 seconds.  
Best results are achieved in calm conditions  
where there is minimal current (best at high or low  
tide).

Enter a negative keel offset value when the depth  
below the deepest part of the boat is required (such  
as the keel, the rudder or the propeller) and the  
transducer is located closer to the water surface.  
Use the cursor keys to select Keel offset,then

Failure to do so could create  
hazardous conditions that can

Calibrating the fuel usage can improve the ac-  
curacy of fuel measurements.  
Twin engine installations require each fuel trans-  
ducer to be calibrated. This can be done at the  
same time with two portable tanks or at different  
times using one portable tank.  
Calibrating the fuel transducer(s) requires accurate  
measurement of the fuel consumption. This is  
best done using a small portable tank. At least 4  
gallons (15 litres) of fuel should be used to ensure  
an accurate calibration.

4 Using the FISH 4500/4600  
This section explains how to interpret the  
sonar displays, when and why to use the dif-  
ferent frequencies and how fish are detected  
and displayed.  
It also describes Gain and Range and shows  
examples of some of the different sonar displays.  
Also see section 1-2 How the FISH 4500/4600  
works.  
4-1 Interpreting the display  
The sonar displays do not show a fixed distance  
travelled by the boat; rather, they display a his-  
tory, showing what has passed below the boat  
during a certain period of time.  
Strength of echoes  
The colors indicate differences in the strength of  
the echo. The strength varies with several factors,  
such as the:  
The history of the sonar signal displayed de-  
pends on the depth of the water and the scroll  
speed setting.  
Size of the fish, school of fish or other object.  
Depth of the fish or object.  
Location of the fish or object. (The area cov-  
ered by the ultrasonic pulse is a rough cone  
shape and the echoes are strongest in the  
middle.)  
Clarity of water. Particles or air in the water  
reduce the strength of the echo.  
Composition or density of the object or bot-  
tom.  
In shallow water, the echoes have a short  
distance to travel between the bottom and the  
boat. In deep water, the history moves across  
the display more slowly because the echoes  
take longer to travel between the bottom and the  
boat. For example, when the scroll speed is set  
to Fast, at depths over 1000 ft. (300 m) it takes  
about 4 minutes for each vertical line of pixels  
to move across the display, whereas at 20 ft. (6  
m) it takes only about 15 seconds.  
The scroll speed can be set by the user to display  
either a longer history with less fish information  
or a shorter history with more fish details. See  
section 3-2 Setup > Sonar.  
Note: Planing hulls at speed produce air bubbles  
and turbulent water that bombard the transducer.  
The resulting ultrasonic noise may be picked up  
by the transducer and obscure the real echoes.  
Kelp / Weed  
If the boat is anchored, the echoes all come from  
the same area of bottom. This produces a flat  
bottom trace on the display.  
The screen shot shows a typical sonar display  
with the Fish symbols turned Off.

Mud, weed and sandy bottoms tend to weaken  
and scatter the sonar pulse, resulting in a weak  
echo. Hard, rocky or coral bottoms reflect the  
pulse, resulting in a strong echo. See section  
5-3 Sonar Bottom display.

The differences in the cone width affect what is displayed. See section 4-2 Single and Dual  
Frequency fishfinding.  
Shadows  
Shadows are created around areas where the ultrasonic beam cannot ‘see’. These areas include hollows  
on the bottom or beside rocks and ledges, where the strong echoes returned off the rocks obscure the  
weak echoes of the fish and may also create a double bottom trace. See following for an example of  
the sonar display in such an environment. A double bottom trace is shown on the display.  
When looking for fish with the wide angled 50 kHz frequency, be aware of increased shadows. Use  
the high frequency 200 kHz in areas that have rocks and ledges because this frequency reduces the  
shadow effect considerably.

4-2 Single and Dual frequency fishfinding  
When to use 200 kHz  
When to use 50/200 kHz  
The 200 kHz frequency is especially suitable  
for use in shallow and medium depth water,  
typically less than 500 ft. (150 m) and while  
running at speed.  
Operating the FISH 4500/4600 at both 50 kHz  
and 200 kHz simultaneously on a split display  
can be very useful when operating in shallow to  
medium water, typically less than 500 ft. (150 m),  
because the 50 kHz section of the display shows  
the general area, while the 200 kHz section can  
be viewed simultaneously for a more detailed  
look at any interesting feature.  
At 200 kHz, the narrow cone reduces any noise  
caused by air bubbles.  
The 200 kHz frequency generates a higher  
definition pulse which produces little shadow and  
returns excellent detail over a small area of bottom.  
Therefore, it gives excellent bottom discrimination  
capability and is particularly good at showing indi-  
vidual fish, including bottom dwellers.  
Mixed frequency  
The Mixed frequency combines the 200 kHz and  
the 50 kHz echoes on one sonar display, filling in  
detailed echoes in the centre of the sonar cone.  
Mixed frequency  
When to use 50 kHz  
The 50 kHz frequency is particularly suitable for  
use in deep water, typically greater than 500 ft.  
(150 m).  
At 50 kHz, the cone covers an area of water  
about four times wider than the 200 kHz cone  
and penetrates to a greater depth with minimal  
loss of the return signal.  
However, it produces a lower definition display  
with more shadow compared to the 200 kHz  
frequency. This means that a group of small fish,  
for example, could be displayed as a single item,  
while any fish very close to the bottom may not  
be found at all.  
Narrow angle,  
more detailed  
200 kHz cone  
Wide angle,

This frequency is useful for getting a deep, wide  
overview of the area so that any areas of interest  
can be identified and then examined in detail with  
the 200 kHz frequency.

4-3 Fish detection and display  
Fish symbols Off  
Where to find fish  
For experienced users this always provides the  
best information as every echo is displayed, wheth-  
er it is surface clutter, a thermocline or a fish.  
The picture in section 4-1 Interpreting the display,  
shows the Sonar display with the Fish symbols  
Off. The fish appear as arches.  
Underwater features like reefs, wrecks and rocky  
outcrops attract fish. Use the 50 kHz or 50/200 kHz  
frequency display to find these features, then look  
for fish by passing over the feature slowly several  
timesusingtheZoomdisplay(seesection5-2Sonar  
Zoom display). If there is a current, the fish will often  
be found downstream of the feature.  
WhenfishingwiththeFISH4500/4600withtheFish  
symbols Off, a weak fuzzy band may appear  
between the bottom trace and surface. This  
might indicate a thermocline - a rapid change in  
water temperature, such as the edge of a warm  
or cold current. The temperature difference  
can form a barrier which the fish may not swim  
through. In fresh water, fish often collect around  
a thermocline.  
Fish arches  
In good conditions and with Fish symbols Off, a  
fish passing through the cone-shaped ultrasonic  
pulse is displayed as a fish arch. The 50 kHz  
frequency uses a wider cone than the 200 kHz  
frequency. This makes the fish arches easier  
to see.  
A fish arch occurs when a fish enters the weak  
edge of the sonar cone, generating a weak echo  
that is displayed as the first pixel of the fish arch.  
As the fish moves closer to the middle of the cone,  
the distance between the transducer and the fish  
reduces and the echo is displayed at progres-  
sively shallower depths, producing the start of an  
arch. When the fish passes directly beneath the  
middle of the cone, the echo becomes strongest  
and thickest. As the fish passes out of the middle  
of the cone the reverse happens with a progres-  
sively weaker and deeper echo.  
Fish symbols  
The fish symbol can be customized or switched  
off altogether so that the echoes are not con-  
verted to fish symbols on the display. See section  
3-2 Setup > Sonar. The differences between Fish  
symbol Onand Off are:  
Fish symbols On  
Using Navman’s SBN-II sonar technology the  
fishfinder analyses all echoes and eliminates most  
false signals and clutter so that remaining targets  
are most likely fish. Depending on the strength  
of the remaining echoes, they are displayed as  
either small, medium or large fish symbols - with or  
without depth. While the SBN-II processing is very  
sophisticated it is not foolproof - there will be times  
when the fishfinder will not be able to differenti-  
ate between  
There are many reasons why fish arches may  
not be seen. For example:  
Poor transducer installation (see Transom  
Transducers Installation Guide).  
If the boat is anchored then fish will tend to  
show on the display as horizontal lines as  
they swim into and out of the transducer  
sonar beam. Slow speeds in deeper water  
give the best fish arch returns.  
Range is important. It will be much easier  
to see fish arches when using zoom mode  
to concentrate on a particular section of  
water, rather than just displaying everything  
from the surface to the bottom. Zooming in-  
creases screen resolution and is necessary  
for good fish arches.  
It is difficult to get fish arches in shallow  
water as the transducer sonar beam is very  
narrow near the surface and fish do not stay  
within the beam long enough to display an  
arch. Several fish in shallow water tend to  
display as randomly stacked blocks of pixels.  
• Wave motion may result in distorted  
fish arches.

4-4 Gain  
Gain (sensitivity) controls the amount of detail  
displayed on the FISH 4500/4600. Understand-  
ing how to set suitable Gain settings is important  
for optimum performance.  
The Navman fishfinder has two gain modes,  
Auto Gain and Manual Gain. Normally the best  
results are obtained in Manual Gain, but practice  
and experience are required to obtain the opti-  
mum settings for different conditions. Therefore,  
the use of Auto Gain is strongly recommended  
when learning to use the fishfinder or when  
travelling at speed.  
Note: The Gain mode  
automatically changes  
to Manual Gain if the gain  
or threshold settings are  
adjusted by the user  
In Auto Gain, the gain adjusts automati-  
cally to compensate for water depth and  
clarity.  
Obtaining the best results  
To obtain the best detection capability for both  
fish and bottom we recommend the use of the  
Sonar A-Scope display:  
1. Set the threshold to 0%.  
2. Adjust the gain until the threshold line is  
just to the right of the unwanted noise.  
In Manual Gain, the gain can be adjusted  
by the user to compensate for water depth  
and clarity.  
High Gain settings may amplify the normal back-  
ground noise until it appears as random pixels.

Zoom Range and Zoom Offset  
On the Sonar Zoom and Sonar Bottom displays,  
a vertical bar is shown on the far right of the  
display. This is the zoom bar. The zoom bar  
shows the zoom range; that is, the area that  
is magnified.  
The Navman fishfinder has two range modes,  
Auto Range and Manual Range:  
In Auto Range, the fishfinder adjusts the  
depth range automatically so the bottom  
is always shown in the lower part of the  
display. The use of Auto Range is recom-  
mended for normal conditions.  
In Manual Range, the fishfinder shows only  
a selected depth range. In areas of rapidly  
changing bottom depth, such as the sea  
floor around pinnacles, it can be useful to  
prevent the display from rescaling to always  
show the bottom. If the bottom is deeper  
than the specified depth range, it will not be  
shown on the display.

The echo strengths shown on the A-scope can  
be useful in recognising the type of fish. Different  
species of fish have different sizes and shapes  
of swim bladders. The air in the swim bladder  
reflects the ultrasonic pulse, so the strength of  
the echo varies between fish species according  
to the size and shape of the swim bladder.  
The user can define the level of the weakest and  
strongest echoes to be shown on the sonar dis-  
plays, by using the Gain and Threshold settings.

of the echo that it returns on the A-scope. Then,  
when that particular echo is seen at future times  
on the fishfinder, it is likely to be the same fish  
species.  
5-6 Fuel display  
Usedshows total fuel used since this was last  
reset with the Clear Usedcommand.  
Remainingshows the amount of fuel remaining  
in the tank(s).  
Flow shows the fuel consumption per hour.  
For twin engine installations, the fuel flow for  
each engine is shown separately. This is useful  
for checking that both engines are under the  
same load.  
Economy is the distance travelled per unit of  
fuel used. The Fishfinder calculates this using  
the fuel used and boat speed (water speed or  
GPS speed - which ever is selected as the speed  
source – see section 3-3 Setup > Fuel).  
The bigger this number, the better the fuel  
economy. Adjust the throttle and trim to achieve  
the best fuel economy.  
To show the Fuel display, press DISP and select  
OtherTab, select Fuel and press ENT.

6-3 Mounting and removing the display unit  
while underway.  
There are two mounting arrangements:  
Protected from physical damage during  
rough sea passages.  
Flush mounting requires a solid panel with  
access behind for wiring and mounting screws.  
After flush mounting, the FISH 4500/4600  
cannot be tilted or moved after installation  
to reduce any unwanted glare or reflections.  
Carefully select the best viewing position before  
installation. This would generally be in a shaded  
area.  
Easy to access the 12/24VDCpower source.  
Convenient to route the transducer cables.  
Flush Mounting  
1. Cut a hole in the bulkhead for the display unit  
using the flush mount template.  
2. Drill four holes for the mounting studs using  
the flush mount template.  
Bracket mounting requires a panel for mount-  
ing the bracket. Ensure that the panel is not  
likely to deform and is not subject to excessive  
vibration. The bracket can be tilted and rotated  
so the FISH 4500/4600 can be removed after  
each use.  
3. Screw the four studs into the brass inserts in  
the back of the display unit.  
4. Sit the display unit in place and fit the  
washers and nuts to the studs.  
Bracket Mounting  
1. Fix the mounting bracket onto the boat using the  
threestainlesssteelscrews.Donotovertightenthe  
screws, as the bracket may not rotate.  
2. Push the display unit onto the mounting  
bracket and tighten it firmly using the knob on  
the mounting bracket.  
Select a position where the display unit will be:  
At least 4” (100 mm) away from the com-  
pass.  
At least 12” (300 mm) away from any radio  
transmitter.  
At least 4 ft. (1.2 m) away from any antenna.  
Easy to read by the helmsman and crew

the plugs left in the boat are not exposed to the  
elements. Push the attached dust covers over  
the exposed ends of the plugs. Keep the display  
unit in a dry clean place such as the optional  
Navman carry bag.  
Removing the display unit  
The display unit can be removed after each  
use for protection against the environment or  
security reasons.  
When removing the display unit, ensure that  
6-4 Power and transducer connections  
The FISH 4500/4600 has three sockets located  
on the rear of the display unit. These are for  
the:  
Note: Shield is connected to  
pin 1, black wire  
Black connector  
White connector  
Blue connector  
Power/data cable (black locking collar)  
Optional fuel transducer cable (white lock-  
ing collar)  
Transducer cable (blue locking collar).  
The collars must be locked for a watertight  
connection.  
The power cable has a black 8 pin connector  
plug. Push this plug into the upper socket, which  
has a black nut, then turn the collar to lock.  
The optional fuel transducer cable has a white  
8 pin connector plug. Push this plug into the mid-  
dle socket, which has a white nut, then turn the  
collar to lock. (If the fuel transducer cable is not  
being installed, leave the dust plug in place.)  
To engine  
The sonar transducer cable has a blue 6 pin  
connector plug. Push this plug into the lower  
socket, which has a blue nut, then turn the col-  
lar to lock. Do not cut the cable. If necessary,  
extend the cable by adding a Navman 13 ft. (4  
m) extension cable (a maximum of one cable  
can be used).

If possible, route the transducer cable away from  
other wiring on the boat. Electrical noise from  
engine wiring, bilge pumps and other electri-  
cal equipment can affect the display unit. The  
shortest and most direct connection to the boat’s  
battery helps to minimise voltage drop.  
Through hull transducers  
Through hull transducers are supplied with ‘Y’  
adapter cable for connection of both transducers  
into the blue connector.  
Ensure that cable connections do not lie in the  
bilge. Secure the cable(s) at regular intervals.

6-6 Systems of several instruments  
Several Navman instruments can be connected  
together to share data.  
The FISH 4500/4600 is particularly suited to  
work with the TRACKER 5500/5600 - Navman’s  
color display GPS chartplotter with worldwide  
coverage.  
of instruments. Then, if the backlight setting  
is changed in one group, it will automatically  
change for the other instruments in that group.  
However, the backlight setting will not change  
for instruments in different groups.  
If an alarm sounds, mute it by clearing the  
alarm on any instrument which can display  
that alarm.  
There are two ways of connecting instruments  
together; NavBus or NMEA.  
NavBus  
NMEA  
NavBus is a Navman proprietary system that  
allows systems of multiple instruments to be  
built using a single set of transducers. When  
instruments are connected by NavBus:  
NMEA is an industry standard for marine instru-  
ment connections. Data sent by one instrument  
over an NMEA line can be read and displayed  
by another instrument that accepts NMEA  
0183 Version 2. It is not as flexible as NavBus  
as it requires dedicated connections between  
instruments.  
If the units, alarms or calibration are changed  
in one instrument, then the values will au-  
tomatically change in all instruments of the  
same type.  
Please contact your Navman dealer for informa-  
tion on Navman’s full range of NMEA enabled  
instruments and connection options.  
Each instrument can be assigned to a group

6-7 Cleaning and maintenance  
To optimize performance, avoid walking on or  
jamming cables and connectors. Keep the trans-  
ducer free of weed, paint and debris. Do not use  
a high pressure water blast on a speed sensor  
paddlewheel as it may damage the bearings.  
The FISH 4500/4600 screen is covered by a  
proprietary anti-reflection coating. To avoid  
damage, clean the screen only with a damp  
cloth and mild detergent when dirty or covered  
in sea salt. Avoid abrasive cleaners, petrol or  
other solvents.  
When not in use, the FISH 4500/4600 can  
be removed from the installation bracket and  
stored in the Navman carry bag, or left on the  
installation bracket and securely covered with  
the sun cover supplied.  
Cover or remove a transom-mounted trans-  
ducer when repainting the hull. If painting over a  
through hull transducer with antifouling paint, use  
only one coat of paint. Remove the previous coat  
of antifouling paint by sanding it lightly.

Appendix C - Troubleshooting  
This troubleshooting guide is written with the as-  
sumption that the user has read and understood  
the relevant sections in this manual.  
f) Check for corrosion on the power cable  
connector and clean or replace if required.  
g) Check fuses that are placed in line with the  
power cable. A fuse can be blown despite  
appearing to be good or the fuse may be cor-  
roded. Test the fuse or replace it with a fuse  
known to be good.  
It is possible in many cases to solve difficulties  
without having to send the display unit back to  
the manufacturer for repair. Please follow this  
troubleshooting section before contacting the  
nearest Navman dealer.  
There are no user serviceable parts. Specialized  
methods and testing equipment are required to  
ensure that the display unit is reassembled cor-  
rectly and is waterproof. Users who service the  
product themselves will void the warranty.  
Repairs to the product may only be carried out  
by a service centre approved by Navman. If the  
product must be sent into a service centre for  
repair, it is essential to send in the transducer(s)  
at the same time.  
More information can be found on our Website:  
2. The fishfinder won’t turn off:  
The fishfinder may have been wired forAuto  
power. In this case, the fishfinder cannot be  
turned off while the ignition power is on. (See  
Auto power wiring in section 6-5 Wiring op-  
tions.)  
3. The fishfinder operates erratically:  
a) Check that the transducer does not have de-  
bris (e.g. weed, plastic bag) caught around  
it.  
b) The transducer may have been damaged  
during launching, running aground or while  
underway with debris etc. If the transducer has  
been impacted, it may have been kicked up  
on the bracket. If it is not physically damaged,  
reset the transducer back to its original posi-  
tion. (See the Transom Transducer Installation  
Guide.)  
1. The fishfinder won’t turn on:  
a) The FISH 4500/4600 is designed to operate  
on a 12/24 volt battery system, where the  
voltage may vary from 10 to 35 volts. If an  
excessive voltage is supplied, a fuse will be  
tripped, turning the display unit off. Check  
the fuse.  
c) When the transducer is less that 2 ft. (0.6 m)  
from the bottom, the depth readings may  
become inconsistent and erratic.  
d) Manual Gain may be set too low, which may  
cause weak bottom echo or no fish signals. If  
in Manual Gain, try increasing the Gain.  
e) Ensure the back of the bottom surface of the  
transducer is slightly lower than the front and  
the front is as deep in the water as possible  
in order to minimize the generation of bub-  
bles through cavitation. (See the Transom  
Transducers Installation Guide.)  
b) Check that the power cable connector at the  
back of the display unit is securely plugged  
in and the collar is locked in place. The collar  
must be secure for watertight connection.  
c) Measure the battery voltage while the battery  
is under load - turn on some lights, radio or  
other electrical equipment connected to the  
battery. If the voltage is less than 10 volts:  
f) Check the transducer and power cable  
connectors at the back of the display unit  
are securely plugged in and the collars are  
locked in place. The collars must be secure  
for watertight connection.  
g) Inspect the power cable from end to end for  
damage such as cuts, breaks, squashed or  
trapped sections.  
h) Ensure there is not another fishfinder or depth  
sounder turned on, which may interfere with  
this fishfinder.  
-
the battery terminals or wiring on the  
terminals may be corroded.  
the battery may not be charging cor-  
rectly or may need replacing.  
-
d) Inspect the power cable from end to end  
for damage such as cuts, breaks, squashed  
or trapped sections.  
e) Ensure that the red wire is connected to the  
positive battery terminal and the black wire  
to the negative battery terminal. If wired for  
theAuto Power option, ensure the yellow wire  
is connected to the ignition circuit. Also check  
the boat’s main switch circuit (see section 6-5  
Wiring options).  
i) Electrical noise from the boat’s engine or  
an accessory may be interfering with the  
transducer(s) and/or the Navman fishfinder.  
This may cause the fishfinder to
