FISH 4500/4600 Installation and Operation Manual 3

NAVMAN

1 Introduction

Congratulations on choosing a Navman fish­finder. For maximum benefit, please read this
manual carefully before installation and use.

This manual describes how to install and set up
the FISH 4500/4600 and the associated dual­frequency transom transducer. (If a through
hull transducer is used, refer to the Installation
Instructions supplied with that transducer.)

This manual also explains how to operate the
FISH 4500/4600 effectively and provides trou­bleshooting information and performance tips.

Important

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, dual­frequency 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 customiz­able, with a choice of four 16 color palettes and
one 8 color palette. The colors represent differ­ent signal strengths, making the sonar displays
easy to interpret.

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.

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, includ­ing 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.

FISH 4500/4600 Installation and Operation Manual4

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 disap­pearing 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 af­fected 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.

within the palette represents a different echo
strength, as shown on the sonar displays

There is a choice of five col or palettes: Black, Blue,
White, Vivid and 8 color. The first four display
more detail, whilst the 8 color palette shows a
greater distinction of signal strength between each
adjacent color. For the 16 color palette, each color
covers 1.5 dB signal range. For the 8 color palette,
each color covers 3 dB signal range.

Interference filter

This filters the echo signal to reduce high-level,
spiky interference, such as engine noise.

Select to add filter.

Pulse length

This can be used to specify the length of the
transmitted ultrasonic pulse. A short pulse length
improves the display detail but contains less
energy, therefore it does not penetrate as deeply
into the water as a longer pulse.

There is a choice of Auto, Short, Medium or
Long. The Auto setting is recommended.

Pulse power

This can be used to specify the power output of
the transmitted ultrasonic pulse. Low power output
conserves the boat’s battery and produces a clear

underfloor tanks.

Warning

Navman fuel kits are only suitable for petrol/
gasoline engines. Fuel consumption can change
drastically depending upon the boat loading
and the sea conditions. Always carry adequate
fuel for the journey, plus a reserve.

Tank full

Select Tank full each time the fuel tank(s)
are completely refilled. When asked Are
you sure? select Yes. Otherwise, the read­ing on the Fuel display (see section 5-6 Fuel
Display) and the Low Fuel Alarm (see section

NAVMAN

FISH 4500/4600 Installation and Operation Manual10

Set remaining

Before doing a partial refill of the tank or remov­ing fuel manually from the tank (for example, by
siphoning it off):

1. Note the Remaining reading 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 remaining and update

the reading.

It is essential to do this whenever some fuel
is added or removed. Otherwise, the read­ing on the Fuel display (see section 5-6 Fuel
Display) and the Low Fuel Alarm (see section
3-5 Setup > Alarms) are meaningless.

Clear used

Select Clear used to set Used (the amount
of fuel used) to zero. Do this to start measuring the
amount of fuel used over a certain time or distance.
When asked Are you sure? select Yes.

Tank size

Enter the capacity of the fuel tank.

Num engines

Set the number of engines to 0, 1 or 2. If 0 is
selected the fuel features are turned off.

Calibrate

See section 3-8 Setup > Calibrate, for information
about calibrating the fuel transducer(s).

3-4 Setup > Logs

Press MENU one or more times until the Setup
menu is displayed, then select Logs:

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.

For twin engine installations, the fuel flow for each
engine must be adjusted separately.

The Flow filter can be set from 0 to 30 seconds. Use
the lowest value which gives a stable flow. Usually a
value of 5 to 10 seconds will give a satisfactory result
for two-stroke carburettor engines. Fuel injected or
four-stroke engines may require a larger value.

This setting affects the Fuel flow and Fuel
economy reading on the Fuel display (see section
5-6 Fuel display) but it does not affect the Fuel
used reading.

Speed Source

Select speed input from water speed transducer or
external GPS source (an external GPS source must
be connected to the Fishfinder via NavBus or NMEA
comms – see section 3-7 Setup > Comms.)

The values can be changed independently of
each other. These log values are saved when
the unit is turned off.

Reset trip dist

This resets the trip distance to zero.

Reset total dist

This option resets the total distance to zero.

Reset engine hours

Use this option to reset the engine hours to
zero. This can be useful after an engine service
or to count the engine hours between service
intervals.

readout, first measure the water temperature with a
thermometer known to be accurate.

Use the cursor keys to display the temperature
readout box, then increase or decrease the value
to match the measured temperature. The tempera­ture can be set from 32° to 99.9°F (0° to 37.7°C)
with a resolution of 0.1° unit.

To change the units between °F (Fahrenheit) or °C
(Celsius), see section 3-6 Setup > Units.

Temp filter

Increase this setting to stabilise an erratic tem­perature reading. Decrease to improve reading
responsiveness. The temperature filter can be
set from 0 to 30 seconds.

Fuel

Warning:

Extreme precautions must be
observed when carrying out this
procedure.
Failure to do so could create
hazardous conditions that can
cause serious personal or
property damage.

Calibrating the fuel usage can improve the ac­curacy of fuel measurements.

Twin engine installations require each fuel trans­ducer 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.

It is often very difficult to fill underfloor tanks to the
same level twice due to air pockets, so the more fuel
used, the more accurate the calibration.

To calibrate the fuel transducer(s), perform the
following steps:

1. Record the level of the fuel in the tank(s).

2. Connect the portable tank(s) to the engine
through the fuel transducer(s).

3. Run the engine at normal cruising speed until
at least 4 gallons (15 litres) of fuel has been used
per engine.

4. Check the actual amount of fuel used per
engine by refilling the portable tank(s) to the origi­nal level and noting the reading(s) from the fuel
dispenser’s gauge.

5. Select Fuel. Use the cursor keys to change
the reading for each engine to match that on the
fuel dispenser’s gauge.

6. Press ENT when the reading is correct.
Note: If the fuel calibration options appear to give

erroneous readings after a while, first check that the
fuel sensor has been installed correctly according
to the installation instructions supplied with it. Then
see Appendix B - Troubleshooting.

Keel offset

Keel offset is a depth correction representing the verti­cal distance between the depth transducer and the

location from which the depth is to be measured.
Enter a positive keel offset value when the trans-

ducer is located below the water surface but the
total depth is required.

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

4 Using the FISH 4500/4600

This section explains how to interpret the
sonar displays, when and why to use the dif­ferent frequencies and how fish are detected
and displayed.

4-1 Interpreting the display

The sonar displays do not show a fixed distance
travelled by the boat; rather, they display a his­tory, showing what has passed below the boat
during a certain period of time.

The history of the sonar signal displayed de­pends on the depth of the water and the scroll
speed setting.

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.

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.

Also see section 1-2 How the FISH 4500/4600
works.

Strength of echoes

The colors indicate differences in the strength of
the echo. The strength varies with several factors,
such as the:

• 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.

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

Soft bottoms
such as mud,
weed and
sand show
as narrow
bands

Hard bottoms
such as
rock or coral

bands

Bottom types

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.

NAVMAN

Frequency and cone width

The pulse generated by the FISH 4500/4600
transducer travels down through the water,
spreading outwards to form a rough cone shape.
However, the cone width is dependent upon
the frequency of the pulse; at 50 kHz it is 45°,
whereas at 200 kHz it is 11°. The chart shows
how the cone width varies over depth for each
frequency used. Figures are approximate.

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

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.

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 indi­vidual fish, including bottom dwellers.

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.

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.

When to use 50/200 kHz

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

be viewed simultaneously for a more detailed
look at any interesting feature.

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.

4-3 Fish detection and display

Where to find fish

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
times using the Zoom display (see section 5-2 Sonar
Zoom display). If there is a current, the fish will often
be found downstream of the feature.

When fishing with the FISH 4500/4600 with the Fish
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 symbols

The fish symbol can be customized or switched
off altogether so that the echoes are not con­verted to fish symbols on the display. See section
3-2 Setup > Sonar. The differences between Fish
symbol On and 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 - th ere will be times
when the fishfinder will not be able to differenti­ate between
large air bub­bles, rubbish
containing air,
fishing floats
etc. and gen­uine fish.

The follow­ing picture
shows the
Sonar display
with the Fish
symbol: On +
depth:

FISH 4500/4600 Installation and Operation Manual 19

Fish symbols Off

For experienced users this always provides the
best information as every echo is displayed, wheth­er 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.

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 progres­sively 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 progres­sively weaker and deeper echo.

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 in­creases 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.

NAVMAN

4-4 Gain

Gain (sensitivity) controls the amount of detail
displayed on the FISH 4500/4600. Understand­ing 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 opti­mum settings for different conditions. Therefore,
the use of Auto Gain is strongly recommended
when learning to use the fishfinder or when
travelling at speed.

• In Auto Gain, the gain adjusts automati-

cally to compensate for water depth and
clarity.

• 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 back­ground noise until it appears as random pixels.

Changing between Auto and Manual

To change between Auto Gain and Manual
Gain:

1. From any Sonar display, press ENT.

2. Use the

Auto or Manual, then use the
sor keys to select the required mode.

Adjusting Gain and Threshold settings

The gain settings and the threshold settings can
be adjusted independently for each frequency
(50kHz and 200 kHz).

Use threshold to eliminate colors in the sonar
display.

1. From any Sonar display, press ENT.

2. Use the or cursor keys to highlight the
desired setting, then use the
keys to change it.

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.

4-5 Range

Range is the vertical depth displayed on the
FISH 4500/4600.

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 recom­mended 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.

Changing the Range Mode

Press the + or - key to change to Manual Range
mode and to increase or decrease the range to
the desired depth. Values can be set between
10 ft. (3 m) to 2000 ft. (600 m).

To change from the current mode:

1. From any Sonar display, press MENU to

display the Options menu.

2. Highlight Range, then use the cursor keys
to select Auto or Manual.

Fish recognition

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.

When fishing among a school of fish and catch­ing them, note the fish species and the strength
of the echo that it returns on the A-scope. Then,

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.

Note: when water speed is selected as the speed
source, calibration of the boat speed measure­ment is essential for an accurate fuel economy

to reduce any unwanted glare or reflections.
Carefully select the best viewing position before
installation. This would generally be in a shaded
area.

• 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.

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

FISH 4500/4600 Installation and Operation Manual 27

while underway.

• Protected from physical damage during

rough sea passages.

• Easy to access the 12 / 24 V DC power 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.

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

three stainless steel screws. Do not overtighten the
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.

3. Attach the cables.

NAVMAN

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

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.

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:

• Power/data cable (black locking collar)

• Optional fuel transducer cable (white lock­ing 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 mid­dle 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.)

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 col­lar 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 electri­cal equipment can affect the display unit. The
shortest and most direct connection to the boat’s
battery helps to minimise voltage drop.

Ensure that cable connections do not lie in the
bilge. Secure the cable(s) at regular intervals.

NAVMAN

FISH 4500/4600 Installation and Operation Manual30

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.

There are two ways of connecting instruments
together; NavBus or NMEA.

NavBus

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:

• If the units, alarms or calibration are changed

in one instrument, then the values will au­tomatically change in all instruments of the
same type.

• Each instrument can be assigned to a group

DEPTH 2100

REPEAT 3100
Repeater for depth, speed, water temperature and battery voltage.

Accepts NavBus or NMEA data inputs from other instruments.

Depth Repeater

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.

NMEA

NMEA is an industry standard for marine instru­ment 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.

Please contact your Navman dealer for informa­tion on Navman’s full range of NMEA enabled
instruments and connection options.

6-7 Cleaning and maintenance

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.

Cover or remove a transom-mounted trans­ducer 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.

FISH 4500/4600 Installation and Operation Manual 31

To optimize performance, avoid walking on or
jamming cables and connectors. Keep the trans­ducer 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.

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.

Appendix C - Troubleshooting

This troubleshooting guide is written with the as­sumption that the user has read and understood
the relevant sections in this manual.

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 cor­rectly 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:
www.navman.com.

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.

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:

- 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
the Auto 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).

NAVMAN

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 cor­roded. Test the fuse or replace it with a fuse
known to be good.

2. The fishfinder won’t turn off:

The fishfinder may have been wired for Auto

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 op­tions.)

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 posi­tion. (See the Transom Transducer Installation
Guide.)

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 bub­bles through cavitation. (See the Transom
Transducers Installation Guide.)

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.

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
