Functional Characteristics
Press CLR to disable the two functions in sequence.
The VRM ring can also be used to set the range for navigation
from the coast, for example to avoid navigating out of the limit
allowed. In this case, set the EBL to any value, adjust the
VRM ring size as desired, then navigate making sure that at
least one point in the ring is always touching the coast.
Easy Pilot function
The Easy Pilot function allows editing temporarily a route set
and followed by the autopilot, but keeping the route unchanged.
This function is useful to make corrections at
once (e.g., because of other boats or to approach
points of interests), without having to edit the
route planned or disable the autopilot.
To enable this function, rotate the knob and
position the EBL on the new route to follow,
then press ENTER. The EBL will change color,
as the boat starts following the new route; the
planned route will be abandoned, although dis-
played. To go back to the planned route, thus
canceling the temporary correction, press CLR.
NOTE: The Easy Pilot function can be enabled only if a route is present.
Overzoom
The Overzoom function allows expanding the chart
The Overzoom does not provide any additional chart detail,
only improves the readability of the available information, act-
ing as a magnifying glass.
When the Overzoom is enabled, the unit will add OVZ to the
scale displayed in the Navigation window.
To enable/disable the Overzoom function, press GOTO to dis-
play the menu bar, then select SETUP, OVERZOOM and ON/
OFF.

Position calibration
All position sensors are affected by intrinsic errors that make
the boat's position incorrect (from few meters to several hun-
dred meters).
The position calibration function allows correcting manually
the position error present in all GPS, provided that this error
is not greater than 2 nautical miles.
Press GOTO and then, by using the joystick, select SETUP,
CALIBRATION and then ON. A message will prompt the user
to move the cursor to the boat's true position, appropriately
enlarged by the ZOOM+ key.
Press ENTER to move the GPS boat's position to the point indi-
cated by the cursor. This operation will save the calibration
for use in future calculations.
NOTE: When the calibration is enabled, the coordinates (latitude/longitude) in the
General Info window will be marked by (*).
To cancel the calibration, press GOTO, select SETUP, CALI-
BRATION and then OFF.
Local time
This function allows entering local time instead of the Green-
wich time (GMT) supplied by the GPS receiver.
To enter local time, press GOTO and then, by using the joy-
range. stick, select SETUP, SET TIME and then LOCAL.
The joystick will allow entering local time as well as confirm-
ing and saving the operation. To cancel local time, press GOTO,
select SETUP, SET TIME and then GMT.
Contrast/Brightness
Press the PWR key to display the CONTRAST/LIGHT window.
Use the joystick to switch from one option to the other and to
adjust the contrast/brightness level.
Press ENTER to exit.
