2. RADAR OPERATION

2.10Measuring the Range

You can measure the range to a radar target three ways: by the range rings, by the cursor, and by the VRM (Variable Range Marker).

2.10.1Measuring range by range rings

Count the number of rings between the center of the display and the target. Check the range ring interval and judge the distance of the echo from the inner edge of the nearest ring.

To turn the range rings on, do the following:

1.If not displayed, press the [HIDE/SHOW] key to show the radar soft keys.

2.Press the RADAR DISPLY soft key.
