FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

1 Introduction

Congratulations on choosing the NAVMAN FISH450 Tricolor fishfinder. For maximum benefit, please

read this manual carefully before installation and use. Special terms are explained in Appendix C.

The NAVMAN FISH450 Tricolor

The FISH450 Tricolor is an ultrasonic fishfinder with powerful software and a three colour display. As well

as detecting fish the unit measures water depth, boat speed, water temperature and battery voltage and

has two distance logs (trip and total with one displayed at a time). With an optional fuel kit the FISH450

Tricolor is also a sophisticated yet easy to use fuel computer.

How the NAVMAN FISH450 Tricolor finds fish and determines the depth

An installed FISH450 Tricolor has two parts:

- a transducer attached to the hull

- the display unit.

The transducer generates an ultrasonic (sound) pulse, which travels down

towards the bottom. When the sound pulse meets an object, such as a

fish or the bottom, some of the pulse is reflected back up towards the boat

and is received by the transducer. The depth of an object can be calculated

by measuring the time between sending the pulse and receiving its echo.

The display unit analyses the reflections from each pulse, removes

unwanted reflections (from bubbles and other noise) and displays what is

in the water under the boat. The display shows three colours: Blue for the

strongest reflections, Red for medium and Green for the weakest reflections

(see section 3 - 2). These colours help users better interpret what is in the water.

There are several reasons the returned echo strength can vary. Larger fish usually return stronger echos, as

do fish in the centre of the beam where the pulse is stronger. Reasons for weak echos include the fish or

object being in deep water or turbid water, or in the edge of the beam where the pulse is weaker.

The unit will detect the bottom down to 1000 feet (300 metres), depending on the clarity of the water and

measures depths to an accuracy of 2%.

Assisting with navigation

The FISH450 Tricolor can be used to find fish, to locate features on the bottom such as reefs or wrecks

and to help recognise favourite fishing spots from the profile of the bottom. Use the FISH450 Tricolor to

assist navigation by following the depth contours marked on charts.

IMPORTANT NOTE ON USE - While the FISH450 Tricolor can be used as an aid to navigation, its

accuracy can be influenced by many factors, including the location of the transducer. It is the user’s

responsibility to ensure the unit is installed and used correctly.

How to find fish

Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the FISH450 Tricolor to find

these features, then look for fish by passing over the feature slowly several times using the Zoom screen

(See section 3-1). Where there is a current, the fish will often be found downstream of the feature.

For deep sea fishing, a rapid change in temperature may indicate the edge of a warm or cold current. The temperature

difference may form a barrier which fish tend not to swim through. Search for fish either side of the barrier.

Cleaning and maintenance

The FISH450 Tricolor should be cleaned with a damp cloth or mild detergent. Avoid abrasive cleaners

and petrol or other solvents.

Always cover or remove the stern mounted Aquaducer when repainting the hull. If painting over a through

hull transducer with antifouling then use only one coat of paint. When repainting the transducer remove

previous coats by lightly sanding.

Temperature warning

Do not expose the unit to temperatures exceeding 50°C (122°F) or the LCD may not be useable until it cools down.

Never leave the unit exposed to high temperatures even for a few minutes. (e.g. on the dashboard of a car).

On the right is the Full Range Section and to

the left is the Zoom Section. Use this screen

for taking a closer look at underwater

features.

Sonar screen (see section 3-3)

Displays the strength and depth of the echos

returned from each ultrasonic pulse. This

screen can also be used for manually setting

the gain and colouration for the Fish History

and Zoom screens.

Fuel screen (see section 3-4)

Displays fuel consumption, fuel used, fuel

remaining, fuel economy, boat speed and

water depth. Fuel Screen will be displayed on

the Main Menu only if the Fuel option has

been enabled (see Setup - Fuel section 4-2).

Data screen (see section 3-5)

Displays water temperature, depth, battery

voltage and boat speed.

Setup menu (see section 4)

The Setup menu allows customising of the

FISH450 Tricolor to individual preferences.

Alarms can be set to suit individual preferences.

Green symbols, visible at the bottom of the screen,

indicate enabled alarms.

Access the Alarms menu by a single press of the

Alarm key (provided the beeper is not active) or

through the Setup screen.

When an alarm condition is met the following

occurs:

• The beeper will sound.

•The Alarms menu will be displayed on the

screen with the activated alarm(s) flashing.

• Each activated alarm’s symbol will flash red.

Pressing the Alarm key will acknowledge the alarm,

stop the beeping, and remove the Alarms menu.

This does not disable the alarm. The symbol will

continue to flash red until the alarm condition is no

longer present.

Note: The Fish Alarm gives three short beeps only.

Alarm automatically re-enables

For Low Fuel, Too Shallow, Too Deep, and Low

Battery, the alarm is re-enabled when the value

moves back outside the alarm condition.

With Temp Value, the alarm is re-enabled when

the temperature is more than 0.25°C / 0.45°F

above or below the trigger value.

With Temp Rate, the alarm is re-enabled when the

rate of change of temperature falls below the trigger

value by more than 0.1°C per minute / 0.2°F per

minute.

External beeper

An external beeper may be installed when a louder

secondary alarm indication is required. This can

be positioned anywhere on the boat. For

installation details see the Installation - Wiring

(section 5-7).

Fish detection

The FISH450 Tricolor analyses all received echos

and recognises the characteristic patterns returned

by fish. These echos are displayed on the screen

as a fish symbol. The default setting is for an

associated depth to be shown with fish symbols.

Advanced users sometimes prefer to turn off the

fish symbol feature and interpret the echo patterns

themselves. The following is an example with fish

symbols turned off:

Fish History screen

The Fish History screen displays the most recent

signals on the right of the screen, and the oldest

signals on the left. Vertically, this screen always

displays between the surface and the selected depth

range. This screen is often used to find fishing spots.

Selected

range

e.g. 0-30 m

3-2 Fish History and Zoom Screens

Zoom screen

The Zoom screen is used to view greater detail in

an area of interest (e.g. fish close to the bottom).

The right portion is the Full Range Section and

the left is the Zoom Section.

The Zoom Bar, located on the very right of the

screen, determines the depth range of the Zoom

Section and the amount of magnification:

The Full Range Section illustrated is 0 to 30 m and

the Zoom Bar is between 14 and 29m. Therefore

the area between 14 and

29m is enlarged in the

Zoom Section.

To set the depth of the

Zoom Section, move the

Zoom Bar up or down by

pressing the Cursor Up

or Down key. To make

the Zoom Bar smaller (to

increase magnification),

press the Cursor Left

key. To make the Zoom

Bar bigger (to decrease

magnification), press the

Cursor Right key.

The Zoom Bar can be adjusted in the Fish History

screen before switching to the Zoom screen.

Strength of returned echos

The three colours indicate differences in the

strength of the returned echo: blue is the strongest,

red is medium strength and green is the weakest.

There are several reasons why the strength of the

returned echo varies:

• The size of the fish, school of fish or other

object.

• The depth of the fish or object.

• The location of the fish or object. The area

covered by the ultrasonic beam is

approximately cone-shaped and strongest in

the centre.

• The clarity of water. Particles or air in the

water reduce the strength of the returned

echo.

• The composition or density of the object. Soft

mud produces weaker echos than rock.

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 echos.

Time

The FISH450 Tricolor like most fishfinders displays the

most recent events on the right of the screen.

Moving boat

Stationary boat

When a boat is stationary, all bottom echos will come from the same small area of

bottom. This will produce a flat bottom trace on the screen as shown on the right.

The appearance of the Fish History and Zoom screens can be

changed to suit individual preferences. This screen has the

depth reading in larger text as a result of the temperature

reading being disabled (see Setup - Display section 4-6).

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

Range

Range is the depth of water displayed vertically.

The FISH450 Tricolor has two range modes, Auto

Range and Manual Range:

• In Auto Range, the unit adjusts the depth

range so that the bottom is shown in the

lower part of the screen. The use of Auto

Range is recommended.

• In Manual Range, the range can be set by

pressing the Increase Range or Decrease

Range key.

To switch between Auto Range and Manual Range

hold the Increase Range or Decrease Range key

down until the dialogue box “Auto Range” or

“Manual Range” briefly appears.

Manual Range is useful to prevent the screen

redrawing when there are rapid changes in depth.

(E.g. looking at the sea floor surrounding a pinnacle.)

Gain

Gain controls the amount of detail displayed on

the screen. The FISH450 Tricolor has two gain

modes, Auto Gain and Manual Gain.

• In Auto Gain, the gain is automatically

adjusted. The use of Auto Gain is

recommended.

• Manual Gain can be set between 1 and 9, low

values may not show enough detail, while too

high a setting may clutter the screen. When in

Manual Gain the gain symbol

appears

followed by the gain level.

To switch between Auto Gain and Manual Gain,

hold the Increase Gain or Decrease Gain key down

until the dialogue box “Auto Gain” or “Manual Gain”

briefly appears.

See the Sonar screen section 3-3 for more

information.

Bottom Lock

Bottom Lock fixes the Zoom Bar to the bottom, so

the bottom is always displayed in the Zoom

Section, regardless of changes in depth.

To turn Bottom Lock on, move the Zoom Bar down

until it touches the bottom and the dialogue box

“Bottom Lock On” briefly appears. To turn Bottom

Lock off press the Cursor Up key.

Should the bottom rise to meet the Zoom Bar when

bottom lock is off, the Zoom Bar will temporarily track

the bottom. This condition will cease when the depth

exceeds the original depth of the Zoom Bar.

Shadows

Shadows are areas where the ultrasonic beam cannot ‘see’. These

include hollows on the bottom or beside rocks and ledges where the

strong echo returned off the rock obscures the weaker echo of the fish.

When looking for small objects including fish, users should consider that

there are places where fishfinders cannot ‘see’.

These fish will be hidden in the bottom echo.

Shadow - where objects are hidden in the bottom echo.

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

The Sonar screen displays the depth and strength

of the echos returned from each ultrasonic pulse.

This raw signal is enhanced by the Colouration

and Gain settings and then displayed on the Fish

History or Zoom screen as a single vertical row of

dots.

The key to interpreting the Sonar screen is to look

at the strength (stronger echos project further to

the left) and the depth (distance down the screen)

of the echos.

Changing the colour thresholds

The Colouration Bar determines which level

(strength) of echos will be displayed in blue, red

or green on the Fish History and Zoom screens.

To display the colouration bar, press the Cursor

Left or Right key.

• Increase the blue part of the colouration bar

by pressing the Cursor Right key if there are

too few blue (strong) echos being displayed.

• Decrease the blue part of the colouration bar

by pressing the Cursor Left key if there are

too many blue echos

being displayed.

The red and green

portions of the bar graph

share the remaining area

equally.

The bar will automatically

turn off when left for four

seconds.

Manual Gain adjustment

The Sonar screen displays all echos returned. If

the Manual Gain value is high, the Fish History or

Zoom screens may become cluttered with too

many weak echos. Use Manual Gain to adjust

the level of received echos that are displayed.

Holding the Increase Gain or Decrease Gain key

for one second or longer switches between Auto

Gain and Manual Gain. A dialogue box will

display “Auto Gain” or “Manual Gain”.

See the Fish History screen section 3-2 for more

information on Manual Gain adjustment.

3-3 Sonar screen

Unwanted weak signals

Fuel screen

The FISH450 Tricolor is also a petrol fuel computer.

To use these fuel features, first purchase and install

the optional single or twin engine fuel kit.

If Fuel does not appear on the Main Menu screen

it must be enabled in the Setup - Fuel screen. To

enable all fuel functions, change Num Engines to

1 (single engine) or 2 (twin engine) as appropriate.

(see Setup - Fuel section 4 - 2)

Setup the tank size and select the fuel unit (L,

USGAL, IMPGAL) to be used as outlined in the

Setup - Fuel section.

3-4 Fuel screen

Used is the total fuel used in litres or gallons since

it was last cleared. This can be reset to 0 by the

Clear Used command in the Setup - Fuel menu

(see section 4-2).

Remaining is the amount of fuel remaining in the

fuel tank(s) displayed in litres or gallons.

Flow (fuel consumption) is shown in litres or

gallons 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 FISH450 Tricolor uses boat speed and

fuel consumption for this calculation. The Economy

units are set by the units selected for speed and

fuel (e.g. NM/L, NM/G, MI/L, MPG, KM/L, KM/G).

Adjust the throttle and trim for the best Economy.

The bigger the number the better the economy.

CAUTION: Fuel economy can change drastically

depending on boat loading and sea conditions.

Always carry adequate fuel for the journey plus a

sufficient reserve.

Speed is the current speed of the boat.

Depth is the current depth of the bottom.

The battery voltage is displayed numerically.

Monitoring this helps prevent the battery running

flat without warning, particularly when using

electronic devices while the battery is not charging.

The battery voltage may provide an early warning

of battery or alternator failure. The battery voltage

will increase after the motor has started if the

alternator is charging correctly.

Log

One of two distance logs can be displayed: Trip

Log or Total Log. Both logs are stored in NAVMAN's

NVM (non volatile memory) when the unit is

switched off. To change the which log displayed see

section 4-6. The Trip log must be reset manually as

most users will want to start and stop during a trip.

Speed is the current speed of the boat.

time the fuel tank is refilled or the low fuel alarm

will be meaningless! When partially filling the fuel

tank use Set Remaining.

Tank Size

Enters the capacity of the fuel tank into the unit for

use with the Tank Full option. It is best to measure

the fuel tank size by draining, then filling with fuel

in the usual manner and using the fuel dispenser’s

meter to measure the amount. Be aware of air

pockets, particularly in underfloor tanks.

Set Remaining

Changes the fuel remaining value. Use this feature

when not filling the fuel tank to capacity, or when

syphoning fuel out.

Clear Used

Resets the fuel used (Used) value to 0.0. Use this

to start re-measuring the amount of fuel used.

Units

Sets the units of fuel to L (Litres), USGAL (US

Gallons) or IMPGAL (Imperial Gallons)

Num Engines

Sets the number of engines to 1, 2 or 0. If 0 is

selected the fuel features are turned off and Fuel

no longer appears on the main menu.

4-2 Fuel

Fuel Cal

Calibrating the fuel usage can increase the

accuracy of fuel measurements from +/- 10% to

better than +/- 2%. For twin engine installations

calibration of each transducer is required.

Calibrating the fuel transducer requires accurate

measurement of the fuel used (Used). This is easiest

with a small portable tank. It should be noted that

due to air pockets, it is very difficult to fill underfloor

tanks to the same level twice. At least 15 litres should

be used to ensure an accurate calibration. (The

more fuel used, the more accurate the calibration

will be.) Each transducer in a twin engine installation

must be calibrated separately. This may be done at

the same time with two portable tanks, or at different

times using one tank at a time.

The procedure is as follows:

1) Reset the fuel used amount on the FISH450

Tricolor to 0.0 by selecting Clear Used in the

Setup - Fuel menu, then selecting Yes .

2) Connect the measurement tank(s) to the

engine(s) via the fuel transducer(s).

3) Run the engine(s) at normal cruising speed

until at least 15 litres is indicated (30 for twin

engines).

4) Check the actual amount of fuel used per

engine. The easiest way to do this is to refill

the tank(s) to the original level(s) and record

the value(s) shown on the fuel dispenser.

5) Select Fuel Cal on the fuel menu. The amount

of fuel that the FISH450 Tricolor has recorded

will be displayed. Use the Cursor Left or Right

key to change this to the actual fuel amount

used. Press the Menu key when the value is

set. (Repeat for the other engine in a twin

engine installation).

Flow Filter

Sets the period over which the fuel flow is

averaged. Averaging can be set from 1 to 255

seconds.

Normally engines do not draw fuel from the tank

at a steady rate. They draw fuel at a high rate for a

few seconds until the carburettor bowl or fuel

injection reservoir is full, then draw no fuel for a

few seconds. If the true flow rate were displayed,

it would be too erratic to read.

Usually a value of 10-15 seconds will give a

satisfactory result for carburettor engines. Fuel

injected engines may require a larger value.

This setting affects the flow rate (Flow) and

Economy displays. It does not affect the fuel used

(Used) measurement.

Speed Cal

To calibrate speed, an accurate measurement of

the boat’s speed is required.

Obtain the speed either from a timed run over a

known distance, or from another instrument (e.g.

GPS, DGPS or calibrated speedometer). The

calibrated instrument may be on board or on

another boat travelling alongside.

Notes for accurate calibration:

• GPS speeds are only accurate enough when

above 20 knots, DGPS when above 5 knots. Best

results are achieved in calm conditions where

there is minimal current (best at high or low tide).

• Paddlewheel devices are generally accurate

enough when between 6 and 20 knots.

5 Installation

Correct installation is critical to the performance of the unit. There are two components to install, the

FISH450 Tricolor and the transducer. The transducer which comes standard with the FISH450 Tricolor is

called an Aquaducer and includes three elements: speed, temperature and ultrasonic sounder.

It is vital to read the entire installation section of this manual and the documentation that comes with your

transducers before attempting installation.

Repeater for Depth, Speed,

Water Temperature, Battery

Voltage. Please consult your

NAVMAN dealer for more

information.

Depth Repeater

19

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

The location and angle of the Aquaducer are the

most critical parts of the installation. If the location

and angle are not correct, the Aquaducer can’t

perform at its designed potential.

Transom mount Aquaducer

IMPORTANT - the Aquaducer cable cannot be cut

or shortened.

The Aquaducer can be installed on any outboard or

stern-drive powered boat. Inboard powered boats must

be fitted with a through-hull transducer as the propeller

wash interferes with the operation of transom mounted

transducers. The transom mount Aquaducer has a

safety “kick up” mounting bracket which will normally

prevent damage to the Aquaducer should it impact

the bottom or floating debris in the water.

Final position of Aquaducer:

Location

Select a position for the Aquaducer that will:

• allow the Aquaducer a smooth flow of water

over its surface at all times.

• ensure a mount as deep in the water as

possible.

• be clear of any interference from the trailer

when launching or retrieving the boat.

• be away from planing strakes or other

projections from the hull that may cause

aerated water to flow over the face of the

transducer.

• be away from the propeller.

• be at least 150 mm (6") away from the keel

of the boat.

Mounting

• IMPORTANT - place the Aquaducer against

the transom and check that the bottom

surface is angled approximately 5° forward

in order to minimise the generation of

bubbles through cavitation. If necessary, use

one or more of the three wedges provided

(one 4° and two 8°) to achieve this angle.

• Position the bracket and selected wedge(s)

as low as possible without any part

protruding below the hull. Mark the screw

hole centres on the transom through the

centre of the bracket slots. Mark them so that

when the screws are tightened the screw

heads sit flat on the surface of the bracket.

• Drill the two screw holes using a 3 mm drill

bit. Make sure the holes are angled so that

when the screws are tightened the screw

heads sit flat on the surface of the bracket.

• Insert the Aquaducer into the

bracket. Use the stainless screws

provided to attach the bracket and

wedge(s) to the transom. Ensure

again that the top of the bracket

is horizontal and that the

bracket is as low as

possible without

protruding below the

hull. Fill holes with a

sealing compound before

inserting screws. Tighten the two screws.

• Drill a hole and insert the third screw in the

middle of the bracket.

• Finally push the Aquaducer down so it

‘clicks’ into place.

• Once in place test the Aquaducer is

connected by turning the unit on. If the

Aquaducer is not connected then the

message “No transducer detected. Enter

simulation mode? Yes/No” will appear. (see

Simulate Mode section 4-10). Please see the

section on Troubleshooting Appendix B.

Appendix B - 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 unit back to the

manufacturer for repair. Please follow this

troubleshooting section before contacting the

nearest NAVMAN dealer.

There are no user serviceable parts. Specialised

methods and testing equipment is required to

ensure that the unit is reassembled correctly and

is waterproof. Users who service the FISH450

Tricolor themselves will void the warranty (see

appendix D.

Repairs to the FISH450 Tricolor may only be

carried out by a service centre approved by Talon

Technology. If it is found that the unit 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 FISH450 Tricolor is designed to operate

on 12 volt battery systems, where the voltage

may vary from 10 to 16.5 volts. If an excessive

voltage is supplied to the unit, a resettable fuse

will be tripped, turning the unit off.

b) Check the power cable connector at the back

of the unit is securely plugged in and the collar

is locked in place. The collar must be secure

for water tight connection.

c) Measure the battery voltage. 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 correctly or

may need replacing.

d) Inspect the power cable from end to end for

damage such as cuts, breaks or squashed

sections.

e) Make certain the power cable’s red wire connects

to the positive battery terminal and the black wire

to the negative battery terminal or ground. (If

wired for Auto Power, then ensure the red and

yellow wires are connected to the boat’s power

switch. Also check the boat’s power switch circuit.

See Auto Power section 5-8.)

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. Test the fuse or replace

it with a fuse known to be good.

2. The fishfinder operates erratically:

a) Check the Aquaducer does not have debris (eg

weed, plastic bag etc.) caught around it.

b) The Aquaducer may have been damaged during

launching, running aground or while underway

with debris etc. If the Aquaducer has been

impacted, it may have been kicked up on the

bracket. If it has not been physically damaged,

push it back down so it ‘clicks’ into place.

c) When in water less than 2 feet (0.6m) the bottom

and depth readings may become inconsistent and

erratic. This depth is measured from the transducer

and does not allow for any Keel Offset setting.

d) Manual Gain may be set too low, which may cause

weak bottom echo, or no fish signals. If you have

the Auto Gain disabled try increasing the gain.

e) Ensure the bottom surface of the Aquaducer is

angled approximately 5° forward and as low as

possible in order to minimise the generation of

bubbles through cavitation. See Mounting the

Aquaducer section 5-3.

f) Check the transducer and power cable

connectors at the back of the unit are securely

plugged in and the collar is locked in place. The

collar must be secure for water tight connection.

g) Inspect the transducer and power cables from

end to end for damage such as cuts, breaks or

squashed sections.

h) Ensure there is not another fishfinder or depth

sounder turned on, which may interfere with the

FISH450 Tricolor.

i) Electrical noise from the boat’s engine or an

accessory may be interfering with the transducer(s)

and/or the FISH450 Tricolor. This may cause the

unit to automatically decrease the gain unless using

Manual Gain. The unit thus eliminates weaker

signals such as fish or even the bottom from the

display. This may be checked by switching off other

instruments, accessories (e.g. fridges) and the

motor until the offending device is located. To stop

problems from electrical noise, try:

- Rerouting the power and transducer

cable(s) away from the boat’s other

electrical wiring.

- routing the unit’s power cable directly to the

battery instead of through a fuse block or

ignition switch.

3. Bottom is not displayed:

a) If in Manual Range and the depth reading is

displayed, check that the depth is not greater

than the range selected. (see section 3-2)

b) The depth may be outside the fishfinder’s range.

24

FISH450 Tricolor FISHFINDER Installation and Operation Manual

NAVMAN

While in Auto Range, the unit will flash the last

depth displayed, then display “--.-” to indicate

that there is no bottom detected. A display of

the bottom should reappear when it is shallower

than 300m (1000 ft).

4. Bottom echo disappears or erratic digital

reading while your boat is moving:

a) Ensure the bottom surface of the Aquaducer is

angled approximately 5° forward and as low as

possible in order to minimise the generation of

bubbles through cavitation. See Mounting the

Aquaducer section 5-3.

b) The transducer may be in turbulent water. Air

bubbles in the water disrupt the echos returned,

interfering with the FISH450 Tricolor’s ability to

find the bottom or other targets. This often

happens when you reverse the boat. The

transducer must be mounted in a smooth flow of

water in order for the unit to work at all boat speeds.

c) Electrical noise from the boat’s motor can

interfere with the FISH450 Tricolor. Try some

suppression spark plugs.

5. Fuel Used and/or Remaining amount(s)

seem incorrect:

a) Running the engine without the FISH450 Tricolor

turned on will result in the fuel used (Used) not

being recorded. This means that the fuel remaining

(Remaining) value will read higher than what is

actually in the tank. Installing the unit in the Auto

Power configuration will solve this problem, as the

unit is powered on and off automatically when the

vessel’s power is switched on and off.

b) Incorrect readings may be caused by fuel surging

back and forward through the transducer in rough

seas. Try installing a one way valve between the

fuel transducer(s) and the fuel tank.

c) Fuel Remaining must be set to the amount of

fuel on board after every refuelling.

d) Air pockets when filling the tank may have

caused the tank to not fill completely.

e) Calibrate the fuel transducer after 100 litres have

been run through - so the turbine shaft beds

into the bearings correctly.

f) Fuel transducers wear out over time and should

be replaced every 5000 litres of fuel.

g) Also check all other fuel problems listed in the

troubleshooting guide.

6. No/low fuel flow (Flow) indicated:

a) Check the fuel cable connectors are securely

plugged in and the collar is locked in place. The

collar must be secure for water tight connection.

b) The fuel transducer(s) must be installed after a

fuel filter or they may clog. To clear a clogged

fuel transducer(s) remove the transducer(s) from

the line and gently blow through the tranducer(s)

in the opposite direction to the fuel flow.

c) Inspect the fuel cable(s) from end to end for

damage such as cuts, breaks or squashed

sections.

d) Check that the fuel filter(s) in the line are clean.

e) Ensure that the fuel flow transducer(s) has not

been exposed to excessive heat or vibration.

7. Only one flow rate value shown for a twin

engine installation:

a) In the Setup Fuel menu Num Engines must be

set to 2.

8. Erratic fuel flow readings:

a) The mounting position of the fuel flow transducer

must not be too close to the fuel pump(s) and

not subject to excess vibration.

b) Check for air leaks in the fuel hose(s) or fuel

pick-up(s) in the tank(s).

c) The filtering level (averaging) has not been set

to suit the engine(s). In the Setup Fuel menu,

increase the Flow Filter value until a steady flow

rate is indicated. Check the fuel flow (Flow)

readings are not zero.

9. No fuel economy reading:

a) For the FISH450 Tricolor to be able to calculate

an economy reading, the boat must be

displaying a speed greater than zero.

b) Check the paddlewheel on the Aquaducer is

spinning freely. Check that the two magnets in

the paddlewheel are in place.

10. Over temperature warning message

displayed:

a) Error message. “Warning: Temperature exceeding

70°C. Reduce temperature to improve colour

clarity.” Press the Alarm key to acknowledge

message and reduce the temperature of the unit.

11. If the unit beeps when turned on but

nothing is displayed:

a) The unit may be operating, but the display’s

calibration settings (Red Cal, Blue Cal, Display

Cal. See section 4-6) may have been set too high

or low. Reset the display defaults so the unit

displays normally. While the unit is off, hold the

Cursor Right key and while holding it, hold the

Power On key. See section 4-9 for default values.

12. The unit is setup in such a way that the

user is not sure what to adjust to get it

operating normally:

a) The units factory defaults can be restored to

reset the unit a known configuration. See

Resetting to factory defaults section 4-9.

13. The wrong language is displayed:

a) See Getting Started section 2 on how to change

the language without using the menu system.

b) See Setup Language section 4-8.

SONDEUR DE PECHE FISH450 Tricolor Notice d'installation et d'utilisation

NAVMAN

1 Introduction

Nous vous remercions d’avoir choisi ce sondeur de pêche FISH450 Tricolor NAVMAN. Pour un

fonctionnement optimal, nous vous recommandons de lire attentivement ce mode d’emploi avant d’installer

et d’utiliser votre sondeur. En appendice C, un lexique définit les termes spécifiques.

Le FISH450 Tricolor NAVMAN

Le FISH450 Tricolor est un sondeur à ultrasons composé d’un logiciel performant et d’un écran 3 couleurs.

Ce sondeur détecte les poissons et mesure la profondeur et la température de l’eau, la vitesse du bateau

et la tension électrique à l’entrée de l’appareil. Il possède un loch journalier et un loch totalisateur (affichage

d'une seule information à la fois). Connecté à un kit essence optionnel, le sondeur FISH450 Tricolor

devient alors une véritable centrale qui vous permet de gérer votre consommation d’essence.

Comment le sondeur FISH450 Tricolor NAVMAN détecte les

poissons et détermine la profondeur.

Le FISH450 Tricolor se compose :

- d’un capteur monté sur la coque - d’un appareil.

Le capteur émet un écho ultrason qui est envoyé vers le fond. Lorsque l’écho rencontre une

cible, tel qu’un poisson ou le fond, une partie de cet écho est renvoyée vers le bateau et est

reçue par le capteur. La profondeur de la cible est calculée en mesurant le temps écoulé entre l’envoi de l’écho

et sa réception par le capteur.

L’appareil analyse l’écho retourné, supprime tous les échos indésirables (bulles et autres parasites) et

affiche ce qui se trouve sous le bateau. Le sondeur utilise 3 couleurs d’affichage, le bleu pour les échos

les plus intenses, le rouge pour les échos moyens, le vert pour les échos de faible intensité (section 3-2).

Ces couleurs facilitent l’interprétation des informations affichées.

Plusieurs raisons peuvent expliquer la différence d’intensité des échos retournés. En général, plus le poisson est

gros, plus l’écho retourné est important. De plus, l’écho retourné par un poisson situé au centre du cône d’émission,

où l’écho émis est plus intense, retournera un écho plus intense. Un poisson situé en eaux profondes, dans des

turbulences ou sur les bords du cône d’émission, où l’écho émis est plus faible, retournera un écho plus faible.

Le sondeur peut détecter un fond jusqu’à 1000 pieds (300 mètres) selon la limpidité de l’eau, le type de

capteur, et mesurer la profondeur avec une précision jusqu’à 2%.

Aide à la navigation

Le FISH450 Tricolor permet de détecter des poissons, de localiser des cibles sur le fond comme des récifs ou

des épaves et de retrouver vos coins de pêche favoris grâce au profil du fond. En suivant les courbes de

profondeur de votre carte papier, vous pouvez utiliser le sondeur FISH450 Tricolor comme une aide à la navigation.

REMARQUE IMPORTANTE CONCERNANT L’UTILISATION DE VOTRE SONDEUR : si vous utilisez votre

sondeur de pêche FISH450 Tricolor comme une aide à la navigation, notez que sa précision dépend entre

autres de l’emplacement du capteur. L’utilisateur doit s’assurer que le capteur est monté et utilisé correctement.

Comment détecter des poissons

Les récifs, les épaves ou les rochers attirent les poissons. Avec le FISH450 Tricolor, repérez ce type de fond puis

recherchez des poissons sur l’écran zoom en passant doucement plusieurs fois au-dessus de cet emplacement

(section 3-1). S’il y a du courant, les poissons se trouvent généralement en aval de cet emplacement. Si vous

recherchez des poissons d’eaux profondes, un changement rapide de la température de l’eau peut indiquer que

vous vous trouvez au bord d’un courant chaud ou froid. La différence de température peut alors former une

barrière que le poisson ne franchira pas. Recherchez les poissons de l’autre côté de cette barrière.

Nettoyage et entretien

Vous pouvez nettoyer votre sondeur FISH450 Tricolor avec un chiffon humide ou imprégné de détergent doux.

N’utilisez pas d’abrasifs, d’essence ou autres solvants. Lorsque vous peignez la coque protégez ou ôtez toujours

l’Aquaducer monté à l’arrière. Si vous appliquez de l’antifouling sur un capteur passe-coque ne passez qu’une

seule couche. Si vous devez appliquer une autre couche ôtez les couches précédentes en sablant légèrement.

Remarque sur la température d’utilisation

Ne pas exposer l’appareil à une température de plus de 50°C (122°F) dans quel cas l’écran ne serait plus

opérationnel jusqu’à ce que la température baisse. Ne jamais exposer l’appareil à de hautes températures

même pendant quelques minutes (ex. sur le tableau de bord d’une voiture).
