Depth Area Limit
Sets a reference depth value (in the range [0 - 30000]): the software fills all the bathymetric areas that
have starting depth area lower than the reference value with grey. All other bathymetric areas are white.
So, if the reference depth is 0, all areas are white, if it is 99.999 all areas are gray. The default setting
is 10 Mt.
'MENU' + "MAP SETUP" + 'ENTER' + "MARINE SETTINGS" + 'ENTER' + "DEPTH AREA LIMITS" + 'ENTER'
To select the unit (Meters (Mt), Feet (Ft) or Fathom (FM)) see Depth (Unit).
Depth Contours
Imaginary lines connecting points of equal water depth (see also Bathymetric Lines).
(NMEA) Depth Trend page
'MENU' + "NMEA DISPLAY" + 'ENTER' + "DEPTH TREND" + 'ENTER'
Shows the graph of the Depth received from the NMEA Port. Pressing 'ZOOM IN'/'ZOOM OUT'
changes the time scale.

Destination
It is the point where the vessel heads. It is also called Target.
DGPS = Differential GPS
Provides even greater positioning accuracy than standard GPS (see Part B of "
Handbook").
Diff(erential) Corr(ection) Source
Allows the selection of the Differential Correction signal source among None, WAAS and External
RTCM. If the "NMEA2/RTCM INPUT" is set to NMEA the option External RTCM cannot be selected.
The chartplotter shows a Warning message. The default setting is WAAS.

(NMEA) Display
'MENU' + "NMEA DISPLAY" + 'ENTER' + "DISPLAY" + 'ENTER'
It is possible to choose the page layout (the number of fields in the page) and the type of data shown
in each of the fields in the page. If the selected type of data is not received the field shows dashes.
