Chart rotation
Cabin
Charts are traditionally displayed in north-up
Regatta
mode. This, however, does not correspond to
reality. For example, when traveling south-
wards, the chart shows, on the right side of
the boat, what is actually located on the left
side, and vice versa.
The Chart Rotation function allows rotating the
electronic chart displayed according to the plot-
ted route (COG - Course Over Ground) as de-
tected by the GPS receiver. Since the COG value
varies continuously, a filter has been inserted
to prevent the chart from bouncing.
To activate the Chart Rotation function, press
PAGE to display the menu, select SETUP, then
CHART ROTATION and ON. A message will
prompt the user to select the requested maxi-
mum range before activating the chart rota-
tion.
Autozoom
With the Autozoom function the GEONAV will
always display automatically the boat's posi-
tion and the target waypoint at the best avail-
able chart range.
As the boat approaches the target waypoint, the unit will automatically
zoom in. Once the waypoint is passed, the unit will select the best range
to display the boat's position and the following waypoint. To activate the
Autozoom function, press ZOOM+ until the "AUTOZOOM ? ENTER = YES"
message is displayed. To deactivate the Autozoom function press the
ZOOM key once. When the GEONAV is turned on, and if at least one
waypoint has been previously entered, the Autozoom function is auto-
matically activated.
Screen Amplifier
This function automatically redraws the chart according to the boat's
course, to maintain 2/3rds of the screen ahead of the boat.
This function will be activated only if no waypoint has been previously
inserted.

Overzoom
The Overzoom function allows the chart scale
to expand anywhere up to 1/4 NM. The
Overzoom does not provide any additional chart
detail, but improves only the readability of the
existing information, acting as a magnifying
glass.
When the Overzoom is activated, the unit will
warn the user by:
•
deactivating the land filling function;
•
replacing RANGE with OVZ (blinking) within
the navigation window.
To activate/deactivate the Overzoom function, press PAGE until the menu
bar is displayed, then select SETUP, OVERZOOM and ON/OFF.
Position calibration
Most position sensors have intrinsic errors that make the boat's posi-
tion incorrect (from few meters to several hundred meters) with respect
to the background display of the chart.
This error is caused by the principle at the root of the satellite-derived
position system. The position calibration allows the user to manually
correct the position error present in all GPS. Press PAGE until the menu
bar is displayed, select SETUP, CALIBRATION and then ON. A message
will prompt the user to move the cursor to the boat's true position by
using the CURSOR key. Press ENTER to move the GPS boat's position to the
point indicated by the cursor. This operation will save the calibration for
use in future calculations.
NOTE: When the calibration is activated, the coordinates will be marked by (*) for safety pur-
poses.
To cancel calibration, press PAGE until the menu bar is displayed, select
SETUP, CALIBRATION and then OFF.
