GP450X INSTRUCTION MANUAL PAGE 3
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.
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
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.
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
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

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

PROXIMITY WAYPOINTS
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.

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.
Note: You cannot erase system generated Waypoints such as

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.
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
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.
