2.  Chart Plotter

You can change the chart scale to change the amount of information shown, or zoom 
in or out at the location you select. The selected chart scale appears at the top left-
hand position on the screen. In the full screen display, the value shown is 1/2 the dis-
tance from the top of the screen to the bottom of the screen.

There are two methods to change the chart scale, the RANGE key, and the cursor with 
the RotoKey.

Use the RANGE key to select a chart scale. When you operate a RANGE key, the 
chart scale changes to the next available setting. Push RANGE IN to decrease chart 
distance, then push RANGE OUT to increase the chart distance. The current chart 
scale is shown in the chart scale indication at the top-left corner. The scale suitability 
indicator helps you select an acceptable chart scale. The background of the indicator 
is white if the scale is acceptable, and red if the scale acceptable.

This method lets you select ranges between 0.0625 and 120 nm. Use the CursorPad 
to put the cursor on the chart scale indication. Press the right-click button to show the 
Range pop-up menu, shown below. Rotate the RotoKey to select a range then push 
the key to validate your selection.
