Functional Characteristics
NOTE: In NIGHT mode, the areas with depths over the limit set, and therefore
navigable under safety conditions, are displayed in black.
Chart loading
At start-up, all the NAVIONICS electronic charts stored in the
cartridge are automatically loaded, provided that a
CompactFlash™ cartridge has been inserted.
Brightness
Press the PWR key to display the LIGHT window. To adjust
the brightness level, press CURSOR. Press PAGE to exit.
Easy View mode
The GEONAV allows doubling the visibility of the electronic
chart. Once the Easy View mode has been enabled, the chart
will be magnified.
Battery management
When the unit is powered by the batteries, a battery-shaped
icon shown in the upper left corner of the screen displays
their charge status. The icon shows when the batteries are
being recharged, provided that the unit is on.
To increase the life of the battery charge, it is possible to set
the automatic switching off of the backlight and screen by
selecting SETUP, and then BATTERY SAVING.
If no unit’s key is pressed during the time interval set, the
backlight and the screen will switch off automatically. As
soon as any key is pressed, the unit will automatically switch
on again.
Keyboard lock
To lock the keyboard, press the “+” and “-” keys simultaneously.
To restore the keyboard operation, press again the “+” and “-”
keys.
