DIAGNOSTIC
The GEONAV features a diagnostic program to verify its cor-
rect performance, once installed, and to detect problems that
may occur during the use of the unit.
To access the diagnostic program, keep pressed any key but
CLR, while pressing the PWR key.
The GEONAV will switch on and carry out automatically a
test of the whole system; as soon as the memory test is com-
pleted, the program will test the LCD, the CompactFlash™
card and the keyboard. Press ENTER to run one test, CLR to skip
to the next one. To exit from the keyboard test, press CLR
twice.
Once the keyboard test is completed, the diagnostic program
allows checking the messages received from the GPS through
the NMEA 0183 port. Hold the knob pressed to freeze the
messages on the screen, then release it to keep on displaying
the new messages sent by the GPS. To test channel 1 (depth
sounder or wind instrument), press GOTO. Press CLR to quit.
After the keyboard, the diagnostic program will test the inter-
nal non-volatile memory and the backlight. Press ENTER to run
one test, CLR to skip to the next one.
Once terminated all tests, press ENTER to re-boot the unit.
WARNING: The internal memory can be cleared by pressing simultaneously the
PWR and CLR keys. This operation will delete all the settings stored in the GEONAV
and restore factory settings.
NOTE: In case of damaged cartridge or abnormal power spikes, the unit might lock,
requiring a power shutdown to restart. In that case, the unit can be turned off without
the need of detaching the power, by simply holding the PWR key pressed for more
than 10 seconds. This function is useful if the unit is panel mounted or flush mounted
and the power switch cannot be easily accessed.

NAVIONICS ELECTRONIC CHARTS
The GEONAV includes a built-in world map. Additional car-
tography details relative to a specific area of navigation are
available from the CompactFlash™ cartridges storing
NAVIONICS Gold™ electronic charts.
NAVIONICS
charts contain a detailed set
of symbols, similar to those
used on official nautical
charts.
To display chart bound-
aries, press the GOTO key to
display the menu, select
SETUP,
BOUNDARIES and, by the
joystick, select ON/OFF to
enable/disable the bound-
aries of the charts stored in
the cartridge.
A small square will locate the area covered by the cartridge
installed; position the cursor within the square and then de-
crease the chart scale by the ZOOM+ key to display the details
of the area covered by the cartridge.
The maximum detail level is obtained within port plans where
the smallest point on screen can be equivalent to approxi-
mately 1 meter, depending on the cartridge type and coverage.
Increasing/decreasing the chart scale
Press the -ZOOM+ key. The current chart scale is shown by a
small segment in the lower right-hand corner of the screen.
Chart scales can range from 512 NM down to 40 ft in Overzoom
mode.
