Object Information

You can set Object Information ON or OFF. When set ON, object information is
displayed in normal chartplotter operation when the cursor is placed over a
chart object for two seconds. When set OFF, no information is displayed.

Waypoint Options

Waypoint Symbols controls whether or not the waypoints are shown on the
Chart display, with their appropriate symbols. The active waypoint, and
waypoints in the current route are always shown.
Waypoint Numbers controls whether or not the waypoint numbers are shown
for any waypoints in the current route.
Default Waypoint Symbol lets you select the symbol you want used for
waypoint display.

Vectors

Heading, Tide and Course Over Ground vectors can be displayed as a line from
your vessel. The length of the vector is determined by your choice of SOG and
the time period. An infinite vector extends to the edge of the chart screen.
Heading Vector indicates your current heading.
COG Vector indicates your course over ground.
Tide Vector indicates the tide angle. Tide information is calculated from the
speed through water, compass and position data.

Radar/Chart Synch

If you have a combined radar/chartplotter display you can select Radar Chart
Sync ON or OFF. When set ON with chart and radar windows displayed, FIND
SHIP can be used to synchronise the radar and chart images.
The chart is redrawn so that its centre matches that of the radar display. The
radar is redrawn to the scale and heading mode of the chart.

Datum Selection

You can select either WGS 84 or LOCAL datum. In LOCAL mode, you are
presented with a list of datums; use the trackball to scroll through the list, then
press ENTER to select the option and close the menu.
When you change datum selection, the system attempts to set any connected
GPS to the new mode, using SeaTalk and NMEA set up commands. A message
shows whether the set up was successful or not.
