Show Past Positions
When the Show Past Positions check box is
ticked, a series of dots appear along on the history
track, showing ownship’s past positions. Unticking

the past position dots. The minimum is 1 minute and the maximum is 120
minutes.
To change the position spacing click in the Desired field and when the
current value changes to green move the trackball to increase or decrease
the value, click again to accept the selected time. When a time is selected
the Displayed time will change to match the desired time.

popup window will appear showing details of the
