CAUTIONS

• The GPS system is operated and controlled by the U. S.

Department of Defence (DOD) who is responsible for its maintenance and accuracy. The accuracy and reliability of all GPS equipment will be affected by any changes in the GPS system. Because of this, your GP450X should only be used as an aid to navigation and should not be relied on to precisely measure distance, direction or position.

• To ensure safe navigation you should constantly compare

information from your GPS against other navigation aids such as paper charts or visual sightings. If there are any variations you should resolve these before continuing. Chart Plotters are not a replacement for ofﬁcially published mariner’s charts. Your GP450X should be used in conjunction with a range of navigation systems such as visual sightings, paper charts and depth soundings. Mariners should never rely on just one navigation tool.

• Please thoroughly read this Instruction Manual before using

your GP450X on your vessel. We recommend you practice with the Simulator mode before you begin real navigation on your vessel.

• Do not open or disassemble your GP450X. Your unit should only be serviced by fully qualiﬁed personnel.

• If the fuse blows, replace it with another fuse of the correct

rating. Using an incorrect fuse could cause a ﬁre or damage the unit beyond repair. If after replacing the fuse, it blows again, you should return your unit to an authorised service agent for repair.

• Your GP450X is designed to operate from a power source of

12 to 24 Volts DC. Operating the unit from voltages outside this range may damage the unit which is not covered by warranty.

GEODETIC CHART SYSTEM

Your GP450X uses the WGS 84 chart datum. This is the standard datum used by GPS based charts worldwide. Some countries may have localised variations of the WGS 84 datum e.g. new charts in Australia may use the GDA 94 datum. The variation between GDA 94 and WGS 84 is so small it can’t be measured by your GP450X and the WGS 84 datum will provide the same positions.

TERMS

BRG (BEARING)

The direction from your vessel to a destination or Waypoint as measured by a compass.

RNG (RANGE)

The distance from your vessel to a destination or Waypoint.

SOG (SPEED OVER GROUND)

The speed of your vessel relative to the ground. GPS systems measure all speed referenced to the ground. This is different to your water speed as water currents can increase or decrease your ground speed.

COG (COURSE OVER GROUND)

Also called a Track, it is the actual path followed by your vessel over the ground. This may be different to your heading as water currents and water movement can cause your real path to drift sideways.

XTE (CROSS TRACK ERROR)

The distance that you are off to the left or right of an intended course.

ETA (ESTIMATED TIME OF ARRIVAL)

The time you are expected to arrive at your destination.

TTG (TIME TO GO)

The amount of time left before you arrive at your destination.

WAYPOINT

A selected destination saved on your GPS unit.

ROUTE

A set of Waypoints saved in a sequence that when activated will guide you to your destination along Waypoints.

MAINTENANCE

Regular maintenance is important to maintain performance. Check the following points regularly to help maintain performance.

• Check that connectors on the rear panel are rmly tightened

and free of corrosion.

• Check that the ground system is free of corrosion and the

ground wire is tightly fastened.

• Check that battery terminals are clean and free of corrosion.

• Check the antenna for damage. Replace if damaged.

• Dust and dirt on the keyboard and display screen may be

removed with a soft cloth. Do not use chemical cleaners to clean the equipment; they may remove paint and markings.

• Use special care when cleaning the LCD Window – it is easily scratched.

ACQUIRING GPS SIGNALS

Before your unit can acquire a GPS position the antenna must be connected and be in full view of the sky. If the antenna’s view to the satellites is obscured by solid objects such as buildings or terrain or even parts of your vessel’s structure, it will not be able to receive signals from those satellites.

When you ﬁrst turn on your GP450X, it will need to download fresh data from the satellites. This data contains important information about the satellites that the GPS receiver requires in order to calculate positions. If your GP450X hasn’t been used recently or you have moved a long way from your last position, it may take a minute or so to download this data and acquire a position. This is known as a ‘Cold’ Fix. Once the data has been downloaded it is stored in the receiver and continuously updated while the receiver is on. This data remains valid for several hours after you turn the unit off, so that, if you turn the unit back on during this period it will use the stored data to reacquire your position much faster (‘Warm’ or ‘Hot’ ﬁx).

Your GP450X requires at least 3 satellites to calculate a 2D position (latitude and longitude) and at least four satellites for a 3D position (latitude and longitude and altitude).

SATELLITE DISPLAY PAGE

The satellite display page provides a sky view of the satellite positions along with their signal strengths. The satellite page is useful for checking the status of your GPS reception.

The sky view consists of an outer ring marking the horizon and an inner ring marking a circle 45 °above the horizon. The dot in the centre represents a spot directly above your location and the top of the page faces north. The satellites are identiﬁed by numbers. The sky view assists in determining which satellites you are receiving and whether any satellites are being blocked by surrounding structures or terrain.

The signal bars indicate the relative strength of the signals being received. Solid bars indicate the satellite is being used in the position ﬁx. A shaded signal bar means the receiver is downloading data from the satellite. Once the data is

Page 4

PAGE 4 INSTRUCTION MANUAL GP450X

downloaded that signal bar will become solid. A hollow bar indicates the receiver is not yet receiving a signal from that satellite (it may be blocked by obstacles).

To access the satellite display page select SATELLITE from the main menu.

The following table shows the receiver status indicators that can be displayed in the top left of the satellite page.

Plotter Display

The plotter display shows your ships position, track history, bearing and range to target, course and speed over ground and zoom range.

The Plotter page allows you to view your current location. It also displays a record of your track along with nearby Waypoints. The ‘ship’ on the screen shows your present position and heading (the bow of the ship points in the direction of travel. At the corners of the screen are displayed the Bearing (BRG), Range (RNG), Course over Ground (COG) and Speed Over Ground (SOG) relative to your destination. Your present Latitude and Longitude is displayed at the bottom of the screen.

If the unit is in ‘cursor’ mode, the Latitude and Longitude will display the position of the cursor on the screen and the BRG and RNG will display values relative to the cursor.

HIGHWAY DISPLAY

The highway display provides a 3D view of your own vessel’s progress towards a destination (Waypoint), along with associated navigation data.

NAVIGATION DATA DISPLAY

The Navigation display provides a sliding compass scale. The vessel arrow in the centre shows your vessel’s present compass heading. The Waypoint Marker shows the direction of your destination Waypoint relative to your track.

Note:

The compass scale requires your vessel to be moving in order to determine your direction. It does not work while your vessel is stationary.

The centre of the page features a sliding compass scale that shows your course over ground (current track) while you are moving. Your present course over ground is indicated by the vessel pointer in the centre of the display. A destination marker shows the Bearing to your destination Waypoint relative to your current track (COG). The compass scale and Waypoint marker work independently to show at a glance the direction of your movement and direction to your destination.

e.g. if the destination marker is to the left or right of your vessel’s current track you should steer towards the marker until it is directly above your vessel’s pointer. Once your vessel’s pointer is aligned with the destination marker, you are travelling towards your destination.

COMPASS DISPLAY

When a destination is set the compass page will guide you to your destination with digital readouts and a graphic compass display which includes a bearing pointer. The Compass page is a good alternative to the highway page when travelling at slower speeds or when making frequent directional changes such as when straight line navigation is not possible due to obstructions or terrain.

Note that the compass page requires your vessel to be moving in order to determine your direction. It does not work while your vessel is stationary.

The centre of the page features a rotating compass that shows your course over ground (current track) while you are moving. Your present course over ground is indicated at the top of the compass ring. A Bearing Pointer in the centre of the compass

ring points to your destination Waypoint relative to your current track (COG). The compass ring and Bearing Pointer work independently to show at a glance the direction of your movement and direction to your destination.

e.g. if the Bearing Pointer points Up you are travelling directly towards your destination. If the Bearing Pointer points in any other direction you must turn towards the pointer until it points Up in order to continue towards your destination.

POSITIONAL NAVIGATION DATA DISPLAY

The positional navigation data display provides GPS status, position in Latitude and Longitude, course over ground, speed over ground and the time and date. This page is useful for determining your current location for relaying to others or for simply conﬁrming the current time or date.

USER CONFIGURABLE NAVIGATION DISPLAYS

There are two User Conﬁgurable Navigation displays that can be set either as ‘Big Number’ navigation ﬁelds or as an analogue Speedometer.

Big Number Navigation Display

The ‘Big Number’ Navigation display is used to show digital navigation information. It can be conﬁgured into 1, 2, 3 or 4 separate ﬁelds on the screen as shown below.

Each ﬁeld can be individually conﬁgured to display

• Time

• Speed over Ground (SOG),

• Cross Track error (XTE)

• Odometer Distance

• Position

• Course over Ground (COG)

• Time to Go (to Destination) (TTG)

• Trip Distance

• External Voltage (Volts)

• Range and Bearing to Waypoint

• Estimated time of Arrival (ETA)

SPEEDOMETER DISPLAY

The Speedometer displays Speed over Ground. The display can be conﬁgured to suit the speed limitations of your vessel or the speed range of a speciﬁc application (such as trolling). The Speedometer has 5 interval calibrations from minimum to maximum. Simply set the minimum speed and the interval speed and the Speedometer will be calibrated automatically. The example above shows the minimum speed set to 0 knots with the intervals set to 10 knots resulting in a Speedometer calibrated from 0 to 40 knots with 10 knot intervals.

CONTROLLING THE PLOTTER DISPLAY

Display Range

You can select the display range (Zoom Level) on both the plotter and highway displays.

Press the Cursor keypad to activate the cursor mode and move the cursor on the plotter display. The cursor moves in the direction of the keypad arrow. To move the cursor diagonally, press the keypad diagonally. To pan the entire screen beyond the currently visible display area, move the cursor beyond the edge of the display screen.

Cursor Turned On

When the Cursor mode is active the cursor ‘cross’ is displayed on the screen and the cursor position is displayed in latitude and longitude at the bottom of the display. The range and bearing from your vessel to the cursor is displayed in the upper corners of the display. You can use the Cursor mode to explore the plotter screen by panning the display or you can move the cursor to a speciﬁc position to store as a Waypoint or select as a destination.

Note: When the Cursor mode is active, the display will remain at the cursor position. If your vessel is moving the vessel icon may move off the screen and be no longer visible. To re-locate the display to your vessel’s position see

’Centering your Vessel’s Position’ further below.

Cursor Turned Off

When the cursor is off the plotter displays your vessel on the screen and your vessel’s latitude and longitude at the bottom of the display. Navigation data is displayed at the screen’s corners. If the track function is turn on, a trail showing a record of your vessel’s movements is shown on the screen.

Centering your Vessel’s Position.

If your vessel is no longer visible on the screen, you can relocate

the display to your vessels position as follows:

1. Press the MENU key,

2. Select SHIP TO CENTRE then press ENT.

The Plotter screen will be restored with the vessel in the centre of the display.

Track Recording

Your GP450X can record a log of your vessel’s movements. Track points are stored in memory at regular intervals and displayed on the screen as a trail extending behind your vessel. The points are stored at distance intervals determined by settings in the Plotter Setup menu. A shorter interval allows more track points to be recorded which provides a more detailed log but uses more memory resulting in a shorter storage time. A longer interval will allow much longer recordings but there will be less detail. Once the track memory becomes full, the current track log will overwrite the oldest track points with newer points. If track recording is not required it can be turned off.

WAYPOINTS

In navigation terminology a Waypoint is a particular location on a voyage. It can be a start point, a destination or an intermediate location along the way. Your GP450X can store up to 999 Waypoints.

Waypoints can be entered into your GP450X in one of three ways;

• from the cursor position,

• from your vessels own current position or

• by manually entering a known latitude and longitude.

ENTERING A WAYPOINT FROM THE CURSOR POSITION

On the Plotter display, use the cursor keypad to place the cursor at the location desired for the Waypoint. You can select the position by reading the latitude and longitude from the bottom of the screen or alternatively, create a position by moving the cursor to a point that is a speciﬁc distance and bearing from your vessel’s current location as indicated by the ﬁelds in the upper left and right of the display.

A Proximity Waypoint is a Waypoint to which a proximity alarm has been applied. The alarm effectively places a ‘circle’ around that location. If you enter the area of the circle the alarm will trigger to warn you of your close proximity to that Waypoint. Proximity Waypoints are useful for warning of dangerous locations such as rocks, shallow water or other hazardous places. The Proximity Waypoint list in your GP450X can store up to 10 Proximity Waypoints.

1. To access the Proximity Waypoint page, from the main menu, select WAYPOINTS and press ENT.

2. Select PROXIMITY and press ENT. The Proximity Waypoint list is displayed.

If you have not yet created any proximity Waypoints the list will be blank otherwise any Proximity Waypoints you have created will be listed. The Waypoint name is displayed on the left. On the right is the distance (circle radius) from the Waypoint at which the alarm will trigger.

While viewing the Proximity Waypoint list, if a Proximity alarm is triggered, an exclamation mark will ﬂash to the right of the affected Waypoint to identify it in the list. The range from your vessel to that Waypoint will also be displayed.

3. To add a Proximity Waypoint, use the

or keys to highlight the ﬁrst blank Waypoint position and press ENT. The standard Waypoint list is displayed.

4. Select the required Waypoint and press ENT. The screen returns to the Proximity Waypoint list. A default alarm distance is applied automatically.

NOTE: You must have ﬁrst stored the required location as a Waypoint.

5. To change the distance at which the alarm will sound, highlight the Waypoint’s alarm distance and press ENT.

6. Use the

or keys to change the number at the cursor position and the or keys to move the cursor position left or right.

7. Press ENT when done.

ROUTES

Often a trip from one place to another involves several course changes requiring a series of Waypoints. This sequence of Waypoints leading you to your destination is called a route. Your GP450X can be programmed to traverse a sequence of Waypoints, automatically advancing to the next Waypoint as you progress, so you do not have to repeatedly switch to the next Waypoint. You can also travel the route in the opposite direction, using it to return back home again.

CREATING ROUTES

The GP450X can hold up to 50 stored routes plus one Route Log. Each route may contain up to 30 Waypoints. If you attempt to store more than 30 Waypoints a message will inform you that you can no longer save additional Waypoints to that route.

A route may be constructed in one of four ways;

• from the cursor

• from the Waypoint list

• from the route list or

• storing your current position either automatically or manually.

CREATING A ROUTE USING THE CURSOR

1. With the plotter screen displayed, use the cursor keypad to place the cursor at the location of the ﬁrst Waypoint (the latitude and longitude of the cursor is displayed at the bottom of the screen).

2. Press the ENT key. The following window appears.

The cursor will be on the second line ready to edit the

Waypoint name if required. A default Waypoint name is offered which is the lowest Waypoint number currently available in your unit.

3. If you are happy to use the default Waypoint number supplied, simply press ENT to register the Waypoint under that number.

If you prefer to change the Waypoint name then use the

or keys to change the character at the cursor position and the or keys to move the cursor position left or right.

The Waypoint name can have a maximum of 6 characters. Press ENT when done.

The Waypoint attribute window is displayed.

4. If required, you can change the latitude and longitude and Waypoint Icon (Mark). You can also replace the time and date with a comment (up to 16 characters). Once any required changes are completed, select LOG RTE and press the ENT key. This will store the Waypoint into the Route Log memory.

Example Route along a River

Page 11

GP450X INSTRUCTION MANUAL PAGE 11

5. Repeat the steps above to log additional Waypoints to the Route Log memory.

Once you have entered and logged all the required Waypoints

for that route, press the MENU key twice to access the main menu. Select ROUTES and press the ENT key.

7. The ROUTE menu will show the assembled route under the LOG heading. The route will be automatically labelled using the ﬁrst and last Waypoints in the route.

8. To save the route, highlight the LOG route (001 -> 003 in the example above) and press the ENT key. The Route processing options are displayed.

9. Select MOVE and press the ENT key. The route will be moved from the Route Log memory to the ﬁrst available sequential route number and the Route Log will listed as empty.

If you wish to edit the route later on, follow the steps described under EDITING ROUTES later in this section.

CREATING A ROUTE FROM THE ROUTE MENU

The following process describes how to create a route using two Waypoints already stored in the Waypoint list. In this example the Waypoints are called RAMP and FISH1.

1. From the main menu select ROUTES and press the ENT key. The Route list is displayed.

2. Select NEW and press the ENT key. The Route Entry screen appears (next column).

The route automatically uses the ﬁrst available route number

(Route 02 in the following example). The ﬁrst Waypoint position 01 is highlighted by default.

3. Press the ENT key. Use the or keys to scroll through the characters at the ﬁrst cursor position. As you scroll through the characters your GP450X looks for stored Waypoints matching the characters you select and displays them. If more than one Waypoint exists with the same ﬁrst letter (e.g. RAMP and RAMP2) use the or keys to move the cursor position left or right to select other letters that spell the name of the Waypoint you require.

4. When the required Waypoint name is displayed (RAMP in this example), press ENT. The next Waypoint position 02 is highlighted. Repeat the steps above to select the next Waypoint (FISH1 in this example). Press ENT when done. You should now have two Waypoints stored in the route.

5. If you enter a Waypoint name that is not in the Waypoint list

your GP450X screen will show the following message:

Press

to choose YES then press the ENT to create a new

Waypoint (or choose NO to return to the Route entry screen).

6. The Waypoint attribute edit window is displayed. Edit the latitude, longitude Icon (Mark) and comments as necessary then select EXIT and press ENT to return to the Route/ entry screen.

CREATING ROUTES FROM THE WAYPOINT LIST

This method is very similar to the method described for creating routes from the cursor.

1. From the main menu select WAYPOINTS and press the

ENT key.

2. Choose LIST or NEAREST and press the ENT key.

The Waypoint list is displayed.

3. Choose a Waypoint from the list and press the ENT key.

The Waypoint attribute page is displayed.

8. Select MOVE and press ENT. The route will be saved in the next available route memory and the LOG route will be cleared.

9. Press the MENU key twice to exit.

CREATING A TRACK-BASED ROUTE

There are two methods by which you can create a track-based route; either by the manual input of track points using the MARK/MOB key or by the automatic inputting of track points from the ROUTES menu. A track-base route is very handy for retracing your track.

Manual Method

This method creates a route by storing a position each time the MARK/MOB key is pressed. Each time you alter your course, store a new position to mark that location. Your GP450X will create a route from these points that can be used for future navigation or as a route to follow when returning home.

1. Press the MARK/MOB key momentarily. The Waypoint attribute window is displayed.

2. Change the name, comment and Waypoint Icon (Mark) if desired, otherwise accept the defaults.

3. Select LOG RTE and press the ENT key

4. Repeat steps 1 to 3 each time you change your heading so that another Waypoint is stored at that location. Up to 30 positions can be saved into the route.

5. When you have entered all the positions you need, use the MENU key to access the main menu. Select ROUTES and press the ENT key.

6. Highlight the LOG route and press the ENT key.

7. Select MOVE and press the ENT key. The route is moved and stored in the next available route memory.

8. Press the MENU key twice to exit.

Automatic Method

This method creates a route by automatically storing positions at intervals of time or distance. Up to 30 positions can be saved into the route

1. Use the MENU key to access the main menu.

2. Select ROUTES and press the ENT key.

3. Select INTERVAL and press the ENT key.

4. Select TIME or DISTANCE as the method by which the position will be stored and press the ENT key.

5. Use the cursor keys to set the value for the time or distance interval and press the ENT key.

For Example;

To record a point every 15 minutes, set the interval to TIME and set the value to 00H 15M.

To record a point every 2 km, set the interval to DISTANCE and set the value to 02.0 km

NOTE: Since each route has a limit of 30 Waypoints, you should choose intervals that will extend the route to last the length of your trip. If you need to use smaller intervals you may need to save the points over several routes.

6. Select VOYAGE ROUTE and press the ENT key. Select START and press the ENT key.

The GP450X will begin storing points according to your settings, starting with your current position. If you wish you can press MENU twice to return to your previous navigation screens. The GP450X will continue to log points in the background. Each time a new point is saved, ‘XXX SAVED’ (where XXX is the Waypoint number) will be displayed at the top of the screen.

When 30 Waypoints have been saved a message will inform you that you have reached the maximum number of Waypoints for your route and you can no longer save any more points. If this happens, press the ENT key to erase the message.

To manually stop saving positions;

1. From the main menu select ROUTES.

2. Select VOYAGE ROUTE and press the ENT key.

3. Select STOP.

The route is automatically saved under the LOG route memory in the ROUTES menu.

To store the route;

MAIN MENU - CONFIGURING

YOUR GP450X

GPS SETUP

The GPS Setup menu smoothes position and course, averages speed, applies position offsets and deactivates unhealthy satellites.

Position Smoothing

If the GPS satellite signal condition becomes temporarily unfavourable, the accuracy of the GPS position can be affected to the point where your position on the plotter may appear to move around even though your vessel is not moving. This effect can be reduced by smoothing the raw GPS measurements so that their effect on your navigation is minimised. The setting range is from 0 to 999 seconds. The higher settings provide more smoothing but will slow the time that the unit responds to valid changes in position, especially at higher speeds. The default setting is 0 seconds. Increase this setting if the GPS position ﬁx is changing greatly when you are not moving.

Speed and Course Smoothing

As with your position, your vessel’s speed and course is directly measured using the GPS satellite signals. This means the raw velocity data will be affected by unfavourable satellite signal

conditions. You can reduce these affects by increasing the Speed and Course smoothing. As with position smoothing, the higher the value you select for Speed and Course Smoothing the more smoothed will be the raw data. If the setting is too high the response to speed and course changes will become slower. The setting range is from 0 to 9999 seconds.

Average Speed (Speed Averaging)

Speed averaging over a period of time is useful for calculating ETA (Estimated Time of Arrival) and TTG (Time to Go). If the averaging period is too long or too short, the accuracy of the ETA and TTG calculations will be affected. The default setting is 60 seconds. The available setting range is 0 to 9999 seconds.

LAT/LONG Offset

The Latitude and Longitude Offset can be used to adjust position accuracy. It is especially useful when you are referencing to a paper chart that is not using the same WGS 84 datum as your GP450X. This could result in the positions measured on your GP450X not matching those on the paper chart. By applying a position offset to your GP450X you can calibrate the measured positions on your GP450X to match those on the paper chart.

Disable SV (Satellite Visibility)

The Disable SV option allows you to deselect satellites that you do NOT wish to use in position calculations. This might be because they have been reported as unhealthy and therefore unreliable or perhaps because their visibility is poor resulting in inconsistent position accuracy. Up to three satellites can be disabled.

Fix Mode

The ﬁx mode allows you to select either 2 dimensional (latitude and longitude) or 3 dimensional (latitude, longitude and altitude) ﬁxes. If 2/3D is selected your GP450X will provide ﬁxes in 3 dimensions where satellite visibility is good. Where satellite visibility is poor your unit will automatically switch to 2D ﬁx mode until the signal improves, with a reduced positional accuracy. To improve positional accuracy in these situations you can manually select the 2D ﬁx mode. You will then be asked to enter the altitude to be used in the calculation, to make the position more accurate.

To apply these settings;

1. From the main menu select GPS SETUP and press the ENT key.

2. Select the SMOOTH POS ﬁeld and press the ENT key.

3. Use the cursor keys to enter a speed smoothing value from 000 to 999 seconds. For example, if you select 3 seconds, your position measurement will be smoothed over a three second period. Press ENT when complete.

PLOTTER SETUP

Track Recording

To record a copy of the ships track, the ships position is stored in memory at regular intervals of distance. A shorter distance interval provides more track points and a more detailed log of your track but more memory is used resulting in a shorter storage time. When the track memory becomes full, the older track points are overwritten by the newer points.

To change the setting press the

or keys to highlight the

‘TRACK REC’ option and press ENT.

Select Distance to deﬁne your own ﬁxed value for the track log interval. The distance interval will remain constant at all zoom ranges.

Select Auto to let the GP450X deﬁne the track log recording interval automaticaly. The interval will change with the zoom range setting.

Bearing Reference

Your vessel’s course and bearing to a destination may be displayed in either True or Magnetic formats. A True bearing is one referenced to the earth’s geographic North Pole. A Magnetic bearing is referenced to the magnetic north pole which is offset from true north. This magnetic variation changes according to your location. The magnetic bearing is identical to that measured by a standard magnetic compass.

It is recommended you select the bearing reference that matches other navigation equipment in your vessel. Select Magnetic to match a magnetic compass or True if you use a gyrocompass. The default setting is Magnetic.

To change the setting

2. Select the BRG REF ﬁeld and press the ENT key.

3. Choose MAG or TRUE as required and press the ENT key.

4. Press MENU twice to return to the navigation screen.

Magnetic Variation

The location of the magnetic north pole is different to the geographic North Pole. This results in a difference in the direction of North between the true and the magnetic headings. This difference is called the Magnetic Variation. The variation is not constant; it varies considerably depending on your location on the earth’s surface. For example, the magnetic variation in Sydney is around 12° East of true north which is quite different from the magnetic variation in Perth of 4° West of true North.

Your GP450X is pre-programmed with all of the earth’s magnetic variations and can automatically apply the correct magnetic offset for your location. However if you prefer, you can enter the magnetic variation manually as described below.

1. From the main menu select PLOTTER and press the ENT key.

2. Select the MAG VAR. ﬁeld and press the ENT key.

INSTALLATION

INSTALLING THE DISPLAY UNIT

Mounting considerations

We recommend spending a little time selecting the best location for your GP450X. The mounting bracket can be rotated to allow the unit to be mounted above, below or behind the unit, enabling it to be installed in a wide range of locations. The unit can also be ﬂush mounted using the four threaded inserts in the rear of the case. Refer to the drawings below.

When choosing a mounting location, please keep in mind the

following points:

• Locate the unit away from exhaust pipes and vents.

• Mount the unit where it is well ventilated.

• Select a location where shock and vibration are minimal.

• Avoid locations which generate electromagnetic elds such

as a motors or generators.

• Allow sufcient space at the sides and rear of the unit and

leave sufﬁcient slack in cables, to facilitate maintenance and servicing.

• Observe the compass safe distance (as noted on the

speciﬁcations page) to prevent interference to a magnetic compass.

Desktop and overhead mounting

Flush Mounting

To ﬂush mount the GP450X, ﬁrst select a suitable panel location. Ensure there is at least 100 mm of clearance behind the panel to allow for the depth of the unit and the ﬁtment of cables etc. You will also need rear access to install the mounting screws from behind the panel.

Use the template to mark up the panel. Take care to ensure your measurements are correct, then cut the hole. Mark the location of the four mounting holes in the corners and drill using a 3 mm drill bit.

Place the GP450X unit in the hole and ﬁx using four M3 brass or stainless steel bolts of the correct length. Refer to the diagrams for details.

Important: When determining the length of the mounting bolts, take care to ensure the thread extends no more than 5 mm into the case otherwise damage to the case may occur. The correct length should be determined by taking the thickness of the panel you are mounting to and adding 5 mm as shown in the diagram (e.g. if the panel is 10 mm thick, your bolts should be no more than 15 mm long. If in doubt pass the bolts through the holes in the panel and measure the extended length. If it exceeds 5mm your bolts are too long and you should cut them to the correct length before use.

INSTALLATION OF ANTENNA UNIT

Mounting the Antenna

Mount the antenna in a location that has an unobstructed view of the sky. Avoid locations that are near obstacles such as masts, cabin, antennas or other equipment that might ‘shade’ the GPS antenna and restrict its visibility to the satellites. For yacht installations avoid mounting the antenna high up on the mast to avoid effects caused by movement of the mast when heeling or changing tack.

The antenna unit is ﬁtted with a standard 25 mm 14 TPI mounting thread allowing it to be installed onto one of a range of threaded ﬁttings available from your local marine shop. These provide mounting options for masts, bow rails or ﬂat surfaces. Ensure the antenna is mounted in an upright position in a location that will minimise exposure to interference from objects and water spray. Do not shorten the antenna cable.

If you have a Radar unit installed, choose a location out of the radar beam. The radar beam may affect the reception of the GPS signal. The location should also be well away from VHF/UHF marine radio antennas. A GPS receiver may receive interference from VHF/UHF transmissions.

If the antenna cable is to be passed through a hole which is not large enough to pass the RF connector, you may unfasten the connector with a needle nose pliers and 3/8-inch open ended Spanner. After running the cable through the hole reﬁt the connector as shown below.

Wiring

The illustration below shows where to connect cables on the rear of the display unit.

GROUNDING

External equipment

Many modern electronic marine devices contain a microprocessor which can radiate small amounts of very low level electronic noise. This can sometimes be heard as interference on other nearby radio equipment, particularly radio receivers. If you are experiencing this, you can reduce its affect by grounding your GP450X using the wing nut ﬁxture on the rear panel. Connect a length of wire from this wing nut to a ground point on your vessel. The ground wire should be kept as short as possible.

Note: Although the signal ground and frame ground are separated, the power line is not isolated. Therefore, if your vessel uses a positive ground installation do not connect the

signal ground to the frame ground when connecting other equipment which is connected to a positive ground battery.

Replacing the Fuse

The 0.5 Amp fuse in the power cable protects the equipment from over current, reverse polarity and equipment fault. If the fuse blows, ﬁnd the cause before replacing the fuse with the correct 0.5 Amp fuse replacement. If the fuse blows again and everything is connected correctly, obtain the advice of a qualiﬁed installer or arrange for your GP450X to be serviced.
