Warning!!!
Electronic charts displayed by the chartplotter are believed to be accurate and reliable, but
they are not intended to substitute for the official charts which should remain your main
reference for all the matters related to the execution of a safe navigation.
For this reason we would like to remind you that you are required to carry on board and
use the officially published and approved nautical charts.
Caution
n Please read through this manual before the first operation. If you have any questions,
please contact the Company customer service or your local dealer.
n The chartplotter is not built water proof. Please give attention to avoid water intrusion
into the chartplotter. Water damage is not covered by the warranty.
n Extensive exposure to heat may result in damage to the chartplotter.
n Connection to the power source with reversed polarity will damage the chartplotter
severely. This damage may not be covered by the warranty.

Introduction
If you have not used a position-finding instrument before and intend to use
your chartplotter for navigating, we suggest that you read this user manual and make sure
you are familiar with its contents.
Chapter "Before You Begin" introduces you to the basic information to get you
start using the chartplotter. Chapter "For the New User" should be read first to become
familiar with your new instrument. Chapter "For the Experienced User" introduces the
advanced features of the chartplotter.
Throughout this user manual, the labelled keys are shown in capitals letters enclosed between single inverted commas, for example 'MENU'; the software keys are shown
in small capitals letters enclosed between single inverted commas, for example 'E
Menu operations are in bold characters listed by keys sequence with the menu names
enclosed between inverted commas, for example 'MENU' + "ADVANCED" + 'EN-TER' + "Fix & Compass" + 'ENTER' means: press the 'MENU' key, moving the
cursor selects the ADVANCED menu, press the 'ENTER' key, moving the cursor again
selects the Fix and Compass menu and then press 'ENTER'. Terms and functions underlined, for example Target, are explained in the chapter 5.

1.1FEATURES
The chartplotter is a computer specifically designed for nautical use but, more
precisely, to ease and speed up all calculations, which so far have been done manually. If
connected to a positioning instrument, the chartplotter displays the current position, the
speed, and the heading of the boat and its track. The user information like Waypoints,
Marks and tracks can then be stored on a User C-CARD, and can be recalled at any time. On
the screen are shown navigation data and cartographic information obtained from electronic charts of C-MAP NT+ C-CARD.

1.2BASICS
The chartplotter is controlled by using 11 keys. 7 keys are labelled and are dedicated
to specific functions. The other 4 are software keys (hereinafter named soft keys) and have
different functions when you select different modes of operation: their labels for the
current functions are shown on the screen immediately above the keys. There is also a
Joystick (see Fig. 1.2) to move a cursor across the screen. As you press a key, a single audio
beep confirms the key action; every time the key pressed is not valid, three rapid beeps
sound indicates that no response is available.

1.3IF YOU NEED ASSISTANCE
If your chartplotter does not operate properly, go to the System Test on Par. 6.6.
Most common operating difficulties can be diagnosed using these tests. If you still need
assistance, call your local dealer, reporting the Software Release and Cartography information available in the About page.
This chapter provides basic information to get you start using the chartplotter; it
will help you to become familiar with the chart display and the functions of the controls
before you start using the chartplotter.

When Home (called also Navigate) mode is set, the cursor is not shown anymore and all
cartographic functions (zoom, scroll, etc.) are leaded by the fix position. The fix is centered
in the map display and the map scrolls underneath as the fix position changes. To deactivate Home mode move the cursor.

The software keys (hereinafter named soft keys) can have different functions
when you select different operations, for example info on cartographic objects, manage-
ment of Marks and Waypoints... . Also they are used from the chart screen or from the
data pages to select one of the data pages available to allow faster access to the page
selection executable from the Main Menu.
When the chart page is selected, the soft key labels are not shown. By pressing one of
the four soft keys their labels for the current functions are shown on the screen immediately
above the soft keys. When the soft key labels are shown, pressing the associated soft key the
relative function is executed. Pressing 'CLEAR' the four soft key labels disappear.
2.1.1 SOFT KEYS CUSTOMIZATION
Note that when the soft keys labels are shown the user can customize them.

2.4SELECTING THE LANGUAGE
It is possible to select the language in which you wish information to be displayed
(for screen labels, menus and options, but it is not affect the map information). The
default setting is English.
The chartplotter uses two types of C-MAP cartridges: either a chart cartridge or a
data storage cartridge. A chart cartridge, called C-CARD, contains detailed charts of the area
covered. A data storage cartridge, called User C-CARD can be used to permanently store
your routes, Waypoints, Marks, Events and tracks (see Par. 4.6).
2.6.1 INSERTING C-CARD
Hold the C-CARD by the short inclined side so that you can see the C-MAP label
(see Fig. 2.6.1):

3.4C-MAP NT+ INFORMATION
As part of C-MAPs continuous Electronic Vector Chart product
development and improvement program, C-MAP NT+, a natural evolution of
our Electronic Chart technology, has been released.
The key points of NT+ can be divided into five main categories:
1. Coverage/Price
2. Chart/Display Presentation
3. New Features/Functions
4. Accessories
5. Compatibility
Looking at the chart displayed on the screen, you will see a variety of objects and
symbols. Refer to the Cartography Reference Guide for their explanation.
The display can be customized for your personal preferences and needs (see the
following paragraphes).
To simplify the customization of the chart display, the map settings are now reorganized in modes allowing the user to choose the preferred setting. Pre-programmed
settings are user selectable from Full, Simple, Fishing, Low and Custom. The default
setting is Custom. The custom selection allows the user to customize the chart to users
preferences. The chart below shows the selections for each mode:
This function allows the user to customize the following selections and is divided
into the following setting menus: Marine Settings, Depth Settings, Land Settings and
Chart Settings. If any of the settings are changed while in the Customize Map mode,
