Bearing Mode
The mode (magnetic or true) of all the bearing and heading data displayed.
This is indicated in the radar status bar after the heading value.
Cursor Reference
The mode of the bearing data displayed for the cursor readout. The bearing
information can be displayed in either of two forms:
• Relative: The bearing relative to your vessel’s heading.
• Mag/True: The actual bearing in either degrees magnetic or degrees true.
This option is only available in Radar mode if your system includes a radar
display and you have heading data from a compass.
If you choose this mode, the selection you made for the previous parame-
ter (Bearing Mode), °M or °T, is displayed in the cursor (Rng/Brg) data
boxes. The current units are shown for the heading value in the status bar
at the top of the screen.
Cursor Readout
This option controls whether the cursor data is shown in latitude and longitude
or in range and bearing. Alternatively, you can show both types of readout, in
separate boxes, or turn the cursor data box off.
You can also turn the cursor readout box(es) on and off during normal
operation, via the
SCREEN
default soft key (see Switching the Cursor Data Box
On and Off on page 3-25).
Day/Night (L755 Monochrome Display)
This option allows you to change the target presentation between day and
night modes.
In the normal day presentation, black targets are displayed on a white
background. If you select
NIGHT
presentation, the picture is reversed, so that
white targets are shown on a black background to reduce the intensity of the
image.
Help
When Help is set to
ON
, a prompt appears when selecting a soft key or menu
choice, and when using the context-sensitive cursor. The help message is
cleared when an action is selected.
