selected for a particular chart or radar panel in the same manner as dual radar described in
"Selecting the radar source" on page 67.
Ú
Note: Some controls that are related to physical properties of the radar itself are not
independent of source. These are Fast Scan, Antenna Height and Bearing alignment.
MARPA is fully independent and up to 10 targets may be tracked for each virtual radar
source.
Up to two independent Guard Zones may also be defined for each virtual radar source.
Using the cursor on a radar panel
By default, the cursor is not shown on a radar panel.
When you position the cursor on the radar panel, the cursor position window is activated
and the cursor menu options are displayed.
To remove the cursor and cursor elements from the panel, select Clear cursor or press the X
key.
GoTo cursor
You can navigate to a selected position on the image by positioning the cursor on the panel,
then using the Goto Cursor option in the menu.
The cursor assist function
The cursor assist function allows for fine tuning and precision placement of the cursor
without covering details with your finger.
Activate the cursor on the panel, then press and hold your finger on the screen to switch the
cursor symbol to a selection circle, appearing above your finger.
Without removing your finger from the screen, drag the selection circle to the desired
position.
When you remove your finger from the screen the cursor reverts to normal cursor operation.
Saving waypoints
You can save a waypoint at a selected location by positioning the cursor on the panel, and
then selecting the new waypoint option in the menu.
In the Chart and Nav panels, you can save a waypoint at the vessel position, when the cursor
is not active, by selecting the new waypoint option in the menu.
Radar sector blanking
(Halo Radar only)
You can define up to four sectors on the PPI inside which no radar data is transmitted. This
enables you to blank-out interference caused by features on your boat or from a secondary
radar. The blanking occurs on the main radar image and radar overlay on a chart. An enabled
sector is shown as a magenta outline with 3 arcs crossing the blanking area. To specify radar
sector blanking, refer to the Halo Radar Installation Manual.
Ú
Note: Radar sector blanking is only available for Halo radars.
