Radar overlay
You can combine the chart with the radar and MARPA functions
to provide target tracking or to help you distinguish between
fixed objects and other marine traffic.
You can enhance the use of your chart by combining it with the
following radar features:
• MARPA.
• Radar overlay (for distinguishing between fixed and moving
objects).
Using the radar to view MARPA targets on the chart
The Mini Automatic Radar Plotting Aid (MARPA) function is used
for target tracking and risk analysis. When the radar overlay is
on, all MARPA targets are displayed in the chart window and
associated MARPA functions can be accessed via the chart.
Using radar overlay to distinguish between fixed and
moving objects
You can overlay radar image data over your chart image allowing
better distinction between fixed objects and other marine traffic.
For best results, switch on Radar-Chart synchronization to
ensure radar range and chart scale are synchronized.
Note: In order to use the Radar overlay feature you must
use an external source for magnetic heading (e.g. fluxgate
compass), you cannot use COG data for radar overlay.
Enabling radar overlay
With the radar turned on and transmitting, with the chart
application in 2D view:
1. Select Menu.
2. Select Presentation.
3. Select Layers.
4. Select Radar.
The radar overlay opacity slider bar control is displayed
showing the current opacity percentage.
5. Adjust the slider bar to the required opacity, or
6. Select Off to turn the radar overlay off.
Accessing radar controls on the chart
From the chart application:
1. Select Menu.
2. Select Radar Options.
Note: Any changes made to the radar options from the chart
application will be applied to the radar application.
Chart scale and radar range synchronization
You can synchronize the radar range in all radar windows with
the chart scale.
When synchronization is switched on:
• The radar range in all radar windows changes to match the
chart scale.
• 'Sync' is indicated in the top left-hand corner of the chart
window.
• If you change the radar range, in any radar window, all
synchronized chart views change scale to match.
• If you change the scale of a synchronized chart window, all
radar windows change range to match.
Synchronizing the chart and radar range
In the 2D chart view:
1. Select Menu.
2. Select Presentation.
3. Select Chart Sync.
4. Select Radar.
Note: Radar range synchronization is not available when the
chart motion mode is set to AUTORANGE.

NOWRad weather overlay
With a suitable weather receiver connected to your multifunction
display, you can overlay NOWRad weather information on the
chart display.
The NOWRad weather overlay provides NOWRad weather
information and reports in the chart application. You can adjust
the intensity of the overlay to achieve optimal visibility of both
chart and weather information.
Note: The NOWRad weather overlay can only be used in
North America and its coastal waters.
Enabling NOWRad weather overlay on the chart
In the 2D chart view:
1. Select Menu.
2. Select Presentation.
3. Select Layers.
4. Select NOWRad.
The NOWRad opacity slider bar control is displayed showing
the current opacity percentage.
5. Adjust the slider bar to the required opacity, or
6. Select Off to turn the NOWRad overlay off.
Viewing weather reports from the chart application
In the 2D chart view:
1. Select Menu.
2. Select Weather Reports.
3. Select Report At to switch between weather reports from
Ship or Cursor location.
4. Select either Tropical Statements, Marine Warnings, Marine
Zone Forecasts, or Watchbox Warnings.
Range rings
Range rings give you an incremental representation of distance
from your vessel to help you judge distances at a glance. The
rings are always centred on your vessel, and the scale varies
to suit your current zoom setting. Each ring is labelled with the
distance from your vessel.
Enabling range rings
In the 2D chart view:
1. Select Menu.
2. Select Presentation.
3. Select Layers.
