Dual Radar (B-type only)
When installing two FAR-3xx0 series radars, the image from both radars (main radar 
and external radar) may be shown together on one radar display. This allows you to 
take advantage of the best characteristics each type of radar has to offer. The dual 
radar function is available only for the B type.

The following should be done from the [RADAR INSTALLATION] menu at the time of 
installation in order to enable the dual radar display:
•  Set the display area on both the main radar and the external radar ([2 COMBINE 
SECTOR], [3 COMBINE RANGE]).
•  Select the number of external radar to use ([4 EXT RADAR]).
•  Turn the dual radar function on ([5 COMBINE FUNC] is set to [ON]).
TT information
When a TT target crosses over the boundary line of the display area, its information is 
passed to the other radar display. Tracking on the TT continues. The number of the 
antenna which acquires a TT target is displayed in front of the TT number.
