FUNCTIONAL CHARACTERISTICS
This chapter describes some of the most important functions
of the GEONAV, as well as the terms most commonly used in
this document.
Switching on/Switching off the unit
To switch the GEONAV on, press the PWR key. To switch it
off, keep the PWR key pressed for more than 1 second.
Internal or external GPS
To make the installation easy, the GEONAV can use either its
own internal GPS receiver or an external receiver, depending
on where the unit is to be installed (indoor or outdoor).
To select the internal or external GPS, press GOTO to display
the menu, select SETUP, then GPS INT/EXT. Press ENTER to
confirm the operation.
Depth sounder
When in depth sounder mode, the GEONAV displays, at the
same time, navigation and sea depth data in graphic form, as
well as water temperature values.
The depth value can be expressed in meters (selected by de-
fault), feet and fathoms; press GOTO to display the menu, se-
lect 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 automati-
cally selects the chart scale and updates the boat’s position on
the screen.
