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.
Datum Selection
You can select either
WGS 84
or
LOCAL
datum. In
LOCAL
mode, you are
presented with a list of datums; use the trackpad 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.
CAUTION:
Changing the chart datum does not cause any waypoint or routes stored
in the chartplotter to move. Waypoints and routes may therefore appear
to be at different positions when you change the datum.
When adding waypoints numerically to the waypoint list, or via SeaTalk,
NMEA or HSB, it is important that they are referenced to the same
datum that the chart is to be operated in.
