Chart Display: Shows the chart under the radar image.
When enabled, the Layers menu appears.
Orientation: Sets the perspective of the radar display.
Crosstalk Rej.: Reduces the appearance of clutter
caused by interference from another nearby radar
source.
Rotation Spd.: Sets the preferred speed at which the
radar rotates. The High Speed option can be used to

detection, for example, when a longer range is selected
or when MotionScope or Dual range is used.
Appearance: Sets the color scheme, look-ahead speed,
and navigation appearance.
Installation: Allows you to configure the radar for the
installation, such as setting the front of the boat and the
antenna park position.

location of the radar scanner on a boat, if the radar
scanner does not align with the bow-stern axis.
1 Using a magnetic compass, take an optical bearing of
a stationary target located within viewable range.
2 Measure the target bearing on the radar.
3 If the bearing deviation is more than +/- 1°, set the
front-of-boat offset.
Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must
