Before transmission begins, the message “Spinning Up” is shown 

while the radar antenna reaches nominal rotation speed. After the 

message disappears, the radar begins painting an image. 

The Radar Page shows a status bar along the top, user-configurable 

digital navigation data down the right side, a Heading Line, and 

Range Rings. Soft keys that allow quick access to radar functions and 

setting changes appear along the bottom of the page.

Use the Range Rings to quickly determine the distance to a target. 

The lower-right corner of the screen contains two scales. The top 

scale value represents the distance from the center of the radar display 

to the outermost complete ring. The bottom scale represents the ring 

separation or the distance between the Range Rings. Use the RANGE 

keys to zoom in or out. The tick marks on the Range Rings are 

arranged with major tick marks at 30 degree increments and minor 

tick marks every five degrees. The tick marks can help in quickly 

determining the azimuth to a target.

The Heading Line is shown from your current position along the path 

of your current heading.
