INTRODUCTION

The GEONAV is a handheld chartplotter that displays the boat’s current position with respect to an electronic chart.

The unit is equipped with a built-in GPS receiver that can track up to 12 satellites simultaneously and be interfaced with:

• An external GPS

• A depth sounder

• An autopilot

The unit can be installed onboard, interfaced with the NMEA instruments and - at the same time - work as a portable instrument, thanks to four AA alkaline cells or rechargeable batteries.

The unit is also equipped with a built-in battery charger that starts operating automatically when the unit is powered. Totally waterproof (IPX7), the unit is equipped with a daylight visible, color TFT display.

Thanks to the GEONAV and a NAVIONICS Platinum™ or Gold™ electronic chart, you will never get lost even in case of fog, bad weather or dark.

The ROUTE function will allow you to plan a trip, MARKERS will allow you to mark points of interest whereas the TRACK function will allow you to record your actual route. Thanks to the unlimited capacity of the new CompactFlash™ cartridges that can also be used on PCs as personal hard disks - the instrument can store a large amount of route, track and marker data.

NAVIONICS Platinum™ charts provide a detailed coverage of all the most popular boating areas, offer new functions - such as 3D display, satellite photographs, etc. - and can be used in

INSTALLATION AND PRECAUTIONS

Precautions

To avoid electromagnetic interference, the GEONAV must be positioned at least 0.35 meters away from magnetic compasses or flux-gate sensors, such as those used on autopilots and remote electronic compasses.

The GEONAV is totally waterproof (IPX7) and weatherproof. It is essential that the battery pack on the unit’s rear side is firmly inserted and tightly screwed and that the battery pack is removed only when the CompactFlash™ or batteries need replacing. Always make sure that, during the replacement operations, the unit is perfectly dry.

NOTE: Any damage caused by the presence of water inside the unit, due to the lack or incorrect installation of the battery pack, is specifically excluded from the warranty.

Cleaning

It is recommended that you use a nonalcoholic product to clean the glass, since alcoholic products may damage the glass surface or make it opaque.

Installation

The GEONAV allows using either the built-in antenna for outdoor installation or an external GPS antenna for indoor use.

NOTE: At start-up, the plotter will select the internal GPS by default.

• Internal GPS: For the best reception of satellites, mount your unit in an open area to allow the built-in antenna to have the best sky visibility. If the instrument is installed so as to allow full horizon visibility, the best performance will be ensured.

•

External GPS:

Instead of a built-in antenna, you can use an external GPS. To connect the GEONAV to an external an-

Battery pack

The battery pack of the GEONAV allows you to use it as a portable unit. Use 4 alkaline cells or rechargeable batteries,

AA size (if possible, high-capacity batteries, 2000mAh or higher).

Make sure that the unit is off and dry when replacing the batteries.

To access the battery slot, loosen the locking screws by means of a coin or the round side of a key, as shown in the figure.

Extract the battery pack, flip it over and loosen the cover locking screws.

Remove the cover and insert the batteries according to the polarity indicated.

Make sure that the “Battery type” selector located in the cartridge slot is positioned correctly, according to the type of battery used (“Rechargeable” position, for rechargeable batteries; “Alkaline” position, for alkaline batteries).

To change the selection, move the small lever by means of a sharp object.

WARNING: All the units are supplied with the battery selector set to “Alkaline”. When using alkaline batteries, the selector has to be set to “Alkaline”. You are warned NEVER to use alkaline-type batteries if the selector is set to “Rechargeable”. In this case the unit can be seriously damaged. This kind of damage is not covered by the warranty. When using rechargeable

English

13

batteries, the selector can be set either to

“Rechargeable” or to “Alkaline”. However the battery charge function is active on condition that the selector is set to “Rechargeable”. The misplacement of the selector may cause the batteries to break, the corrosive liquid to leak out and, consequently, the unit to be damaged. This kind of damage is not covered by the warranty.

Check that the contacts in the battery pack are clean and dry.

Before reassembling the battery pack, make sure that the rubber gasket in the slot and the rubber O-rings tightening the locking screws are clean and in the correct position.

The misplacement of the gaskets, together with any presence of sand, saline residues or dirt, may be detrimental to the tightness of the battery slot since it allows moisture to penetrate into the unit and damage the electronic inner components. This kind of damage is not covered by the warranty.

Reassemble the battery pack carrying out the disassembly operations in reverse order.

Should the battery pack not fit, or fit with difficulty in its seat, check that the CompactFlash™ is correctly inserted.

The partial extraction of the CompactFlash™ blocks the insertion of the battery pack.

The unit can be powered by the batteries only or connected to an external power supply. When the unit is powered by the power supply cable, the inner batteries - if they are of rechargeable type - are fully recharged, after which the inner battery charger is automatically disabled and the batteries disconnected in order to keep their charge.

The depth value can be expressed in meters (selected by default), feet and fathoms; press GOTO to display the menu, select SETUP and then DEPTH UNITS (M/FT/FA).

Navigation mode (Automatic)

The GEONAV enters the Navigation mode as soon as the internal or external GPS receiver transmits a valid fix; when in Navigation mode:

• The manual cursor is not displayed

• The depth sounder window can be accessed

This mode is also called automatic because the unit automatically selects the chart scale and updates the boat’s position on the screen.

English

Functional Characteristics

28

Cursor mode (Manual)

When in Cursor mode, the manual cursor is displayed. It is possible to edit a route, insert or delete markers, display navaid information etc., but it is not possible to gain access to the depth sounder window. By pressing one of the four arrows in the CURSOR key, the unit switches from Navigation to Cursor mode, and the screen is centered in relation to the manual cursor. To return to Navigation mode press PAGE.

Chart rotation

Charts are traditionally displayed in north-up mode. This, however, does not correspond to reality. For example, when traveling southwards, the chart shows, on the right side of the boat, what is actually located on the left side, and vice versa.

The Chart Rotation function allows rotating the electronic chart displayed according to the plotted route (COG -

Course Over Ground) as detected by the

GPS receiver. Since the COG value varies continuously, a filter has been inserted to prevent the chart from bouncing.

To activate the Chart Rotation function, press GOTO to display the menu, select

SETUP, then CHART ROTATION and

ON. A message will prompt the user to select the requested maximum range before activating the chart rotation.

The northern direction will be indicated by the symbol .

Autozoom

With the Autozoom function the

GEONAV will always display automati-

Without rotation

With rotation

English

29

cally the boat’s position and the target waypoint at the best available chart range. As the boat approaches the target waypoint, the unit will automatically zoom in. Once the waypoint is passed, the unit will select the best range to display the boat’s position and the following waypoint.

To activate the Autozoom function, press ZOOM+ until the

“AUTOZOOM ? ENTER = YES” message is displayed, then press ENTER to confirm the operation.

To deactivate the Autozoom function, press the ZOOM key once.

When the GEONAV is turned on, and if at least one waypoint has been previously entered, the Autozoom function is automatically activated.

Screen Amplifier

This function automatically redraws the chart according to the boat’s course, to maintain 2/

3rds of the screen ahead of the boat, provided that the boat’s speed is greater than 3 knots.

This function will be activated only if no waypoint has been previously inserted.

Overzoom

The Overzoom function allows the chart scale to expand anywhere up to 1/4 NM. The

Overzoom does not provide any additional chart detail, but improves only the readability of the existing information, thus acting as a magnifying glass.

Without screen amplifier

When the Overzoom is activated, the unit will warn the user by replacing RANGE with OVZ (blinking) within the navigation window.

To activate or deactivate the Overzoom function, press GOTO to display the menu bar, then select SETUP, OVERZOOM and

ON/OFF.

Position calibration

All position sensors have intrinsic errors that make the boat’s position incorrect (from few meters to several hundred meters) with respect to the background display of the chart.

This error is caused by the principle at the root of the satellite-derived position system. The position calibration function allows correcting manually the position error present in all GPS devices, provided that this error is not greater than 2 nautical miles.

To carry out the calibration, press GOTO to display the menu bar and then, by the CURSOR key, select SETUP, CALIBRA-

TION and then ON. A message will prompt the user to move the cursor to the boat’s true position, appropriately enlarged by the ZOOM+ key.

Press ENTER to move the boat’s position to the point indicated by the cursor. This operation will save the calibration for use in future calculations.

NOTE: When the calibration is activated, the coordinates will be marked by (*).

To cancel the calibration, press GOTO to display the menu bar, select SETUP, CALIBRATION and then OFF.

Local time

By this function the user can enter local time instead of the

Greenwich time (GMT) supplied by the GPS receiver.

To enter local time, press GOTO to display the menu bar, select

SETUP, SET TIME and then LOCAL.

English

31

A window will allow entering local time by using the CURSOR key. Press ENTER to confirm the operation.

20m: display of contours only with depths up to 20 meters

ALL: all depth contours are displayed

Safety contours

This function allows the user to display the depth areas corresponding to the safety contour desired. The options available are:

OFF: no depth area displayed

Other values: the areas with depths up to the value selected are displayed in shades going from darker blue (for lower depths) to lighter blue (for higher depths). The areas whose depths are over the limit set, and therefore navigable under safety conditions, will be displayed in white.

Dryline areas are always displayed in green.

English

Functional Characteristics

32

NOTE: In NIGHT mode, the areas with depths over the limit set, and therefore navigable under safety conditions, are displayed in black.
