3.2.7 RadarChart overlay
Radar and chart images merged into one presentation takes away the
guesswork of interpreting radar information by providing the full
picture. The overlay is a feature under the radar function, which con-
sists of three layers of information. The first layer is the chart with
the ship’s symbol indicating precisely where you are at all times. The
second layer is the radar image with targets. And finally the third
layer adds the coast lines, buoys, lights, user data and other vital
navigational data which always will be shown on top of the radar
targets. Radar operation will be as usual with full access to the radar
control menu. The dedicated chart used with the overlay is adjustable
via the Radar quick menu.
The overlay function will require the following conditions: Valid
position, valid heading information, and Radar orientation mode
must be in NU (North Up) or CU (Course Up). The overlay is disa-
bled in HU (Head Up).
The overlay function can not be activated in the ‘Radar & Chart’
display.

quick menu where you can Hide/Show Overlay Chart or Hide/Show
Overlay User Data, or enter Overlay Chart Setup to turn off some of
the objects if the screen is too cluttered with information.
