Operation

The SEL button selects what is to be displayed, and the CTL button controls the timers.

Pressing SEL sequentially selects to display Local Time, GMT , Flight Time, Elapsed Time, and back to Local Time. In the bottom segment of the display a dot points to the selected display LT, GMT, FT or ET.

FT starts counting when a valid groundspeed was first greater than 30 knots (typically during takeoff) and it will stops when that speed come down to less than 30 knots. ET starts counting when you click on control butoon while ET is selected (the red dot is above ET)

When FT is being displaying ((the red dot is above FT) clicking twice the CTL button resets Flight Time, FT, back to zero. One more click will start it again. The CTL button also stops, resets and starts again Elapsed Time when clicked sequentially, if ET is selected.

Flight Time and Elapsed Time counts up to 59 minutes, 59 seconds, and then switches to hours and minutes.
