9Use the chart overlays

When you're viewing the Chart screen, you can overlay any or all of the following information:

•the Radar returns

•satellite and aerial photographs (if these are available for the area) of any land

•the tide stations, tidal flow and currents

•the location of ports and marinas

•the main road network and sites of interest

9.1Overlay the radar

You can overlay the Radar returns on the Chart screen. This is extremely useful because it can help you to easily interpret the radar image by correlating the radar targets with charted objects.

The Radar overlay is also very useful in conditions of reduced visibility, at night, or in busy or hazardous waters.

You need good heading data to align the Radar returns on the Chart screen correctly. The overlay will work with COG, but you'll get a better result with a good quality, high-speed NMEA heading source such as a gyro compass or the Northstar Heading Sensor.

The range, orientation, motion mode, and center position of the radar are all adjusted automatically to match your chart view. When a chart view has Radar Overlay On, a link is created between Radar Range and the Chart screen zoom level. This means that if you zoom out on the Chart/Radar overlay the Radar Range will increase, and if you change the radar range in the Chart/Radar overlay, the chart zoom level adjusts automatically.

To overlay the radar:

1.Display the Chart screen.

2.Select Chart Overlays. The Radar Overlay button shows the current setting. Select the button if you want to toggle to the other setting. If it's:

ƒOn, the Radar screen overlay is operational. If no Radar screen is

shown, the radar mode may be set to Off or StandBy. (To check this, select Radar Settings, and the Radar Mode button will show the status. To start the radar, select Radar Mode, then

Transmit.)

ƒOff, the Radar screen overlay is not shown.

3.The new setting is applied immediately and stays until you change it again.

4.When you are finished, select Return.
