2.6 How to Measure the Range and Bearing Between
Two Points
You can measure the range and bearing between any two points on the plotter dis-
play.
1. If the cursor is displayed, press the CURSOR ON/OFF key to turn off the cursor.
2. Press the 0 key. A dashed circle appears with the red “X” mark at its center and a
dashed line extends from the “X” mark to the cursor. The [BTWN] data box ap-
pears at the top left of the screen.
3. Use the trackball to put the cursor on the starting point.
4. Push the
ENTER knob then the “X” mark moves to the cursor position.
5. Use the trackball to put the cursor on the ending point. The [BTWN] (Between)
data box shows the range and bearing between the starting and ending points.
6. Press the 0 key to terminate the measurement and erase the dashed circle, line,
and data box.
