OPERATING MODES
When switching on the GEONAV, the user can select one of
the two main operating modes available.
Press the PWR key and wait for the message on official nauti-
cal charts to show (if required, select one chart among those
contained in the cartridge), then press EXIT to enable the STD
mode, or ENTER to enable the standard GEONAV mode. It is
also possible to press GOTO to enter the demo mode, in which
the unit automatically shows, in sequence, different views
relative to the chart currently loaded.
STD mode
This mode allows displaying the chart data according to the
RTCM standard. During navigation, only the ship’s position,
the heading vector and a set of chart items - defined by the
applicable regulations (and known as standard display) - are
displayed at full screen. Markers are not displayed and navi-
gation data are made accessible only by quitting the standard
display. By enabling the manual cursor by the joystick, the
markers will show again, on condition that the relevant op-
tion on the Setup menu (DISPLAY/MARKERS ON/OFF) has
been selected.
Geonav mode
This is the unit standard mode. During navigation, the win-
dows showing position and route (if present) data, as well as
the waypoints and markers, are enabled.
It is not possible to disable the marker display, whose rel-
evant option does not appear in the Setup menu.
In Geonav mode, the unit displays different types of data,
according to the operating mode enabled (Cursor mode or Navi-
gation mode). The following paragraphs will describe the dif-
ferences between the modes available.
