To open the Compass page: Touch Compass. The bearing pointer points to your destination, regardless of the direction you are moving. If the bearing pointer points toward the top of the compass, you are traveling directly toward your destination. If it points any other direction, turn toward that direction until the arrow is pointing toward the top of the compass. Calibrate the compass after moving long distances, experiencing temperature changes, or changing the batteries. To calibrate the electronic compass: 1. While outdoors, hold the Oregon level and do not stand near objects that influence magnetic fields, such as cars, buildings, or overhead power lines. 2. Touch Setup > Heading > Press To Begin Compass Calibration. 3. Touch Start and follow the onscreen directions.  Oregon Series Quick Start Manual
