How to Select a Range Scale

The selected range scale and range ring interval are shown at the upper left corner on
the screen. When a target of interest comes closer, reduce the range scale so that it
appears in 50-90% of the display radius.
1. Place the cursor in the [RANGE] box at the top left corner of the screen.
In the above example, the range scale is set to 0.125 NM and the interval between
range rings is set to 0.025 NM.
2. Left-click to lower the range; right-click to raise the range.
You can also select the range with the RANGE key on the control unit. Press "+" to
increase the range, or press "-" to reduce the range. Press and hold a key to succes-
sively change the range upwards or downwards.
Changing the plotter range
(A/B/W-types with Radar Plotter functionality only)
With the radar in standby (STBY) mode, you can change the plotter range by pressing
the RANGE key. In this case, "range" means the on-screen displayed distance from
the left-hand edge of the screen to the right-hand edge of the screen.
[+]: expands the range scale with the cursor location as the center.
[-]: reduces the range scale with the cursor location as the center.
Press and hold the [+] or [-] key to change the range scale continuously.
