How do I dodge an obstacle in Track mode?
In Track mode you still have full control from the keypad. You can make a
dodge maneuver by using the course change keys (-1, +1, -10 or +10) to se-

After you have avoided the hazard, you can cancel the dodge course change
by making an equal course change in the opposite direction.
