+
C-CARD there will be multiple
charts shown within the same scale range.
Measure DST & BRG: allows measuring the Distance and Bearing between two
points.
Ship Icon: select the preferred icon (among 5 choices) to display ship on the Chart
page.
Cursor Speed: select the preferred speed among Low, Medium and High for the
cursor in the Chart page and in the menu page.

Fix Correction: Enables / Disables the correction of the received fix position.
Compute Correction: Corrects fixes from the positioning instrument. By placing
the cursor on the ship's real position and selecting this option, the error is
calculated and internally memorized for appropriate correction, but not applied.
Correction Offset: Allows entering the correction to the received fix position.
Position Filter: Attenuate the fix position error.
Speed Filter: Attenuate the fix position error.

Map Datum: Allows selecting any datum reference from the ones available on the
chart plotter. The chart plotter allows selecting about 100 different datum. The
default Map Datum is WGS84. C-MAP charts are saved in WGS84 datum. The
Map Datum selection switches to the selected reference datum applying the
datum offsets stored with the charts.
Map Orientation
- North Up: The top of the map is fixed to North.
- Course Up: The top of the map is oriented to the current Course value.
- Track Up: The top of the map is oriented to the current Navigation Leg.
Map Orientation Resolution: 5 – 30 degrees defines the maximum variation of
the reference angle after which the map changes its orientation.
Coordinate System
- Ddd mm.mm: Degrees minutes and hundreds of minutes.
- Ddd mm.mmm: Degrees minutes and thousands of minutes.
- Ddd mm.sss: Degrees minutes and seconds.
- TD: TD function allows converting GPS coordinates to Loran-C coordinates
and vice versa. Any position can be displayed or entered in TDs. The chart
plotter allows choosing one of the (about) 30 Loran-C chains and allows
selecting the two TD stations (Slave 1 and Slave 2). A correction to the TD values
can be applied by entering the correction offset (ASF1 and ASF2) to the slaves.
