Compass

The device has a 3-axis compass with automatic calibration. The compass features and appearance change depending on the profile you are using (Changing Profiles), whether GPS is enabled, and whether you are navigating to a destination. You can also manually change the compass settings (Compass Settings).

Navigating with the Horizontal Situation Indicator

1While navigating, from the time of day page, select .

Course line pointer. Indicates the direction of the desired course

À

line from your starting point to your next waypoint.

Bearing indicator. Indicates the bearing to your next waypoint.

Á

To-and-from indicator. Indicates whether you are headed to or

Â

from the waypoint.

Course deviation indicator (CDI). Indicates the location of the

Ã

desired course line in relation to your location.

Course deviation distance. The dots indicate your distance off

Ä

course.

TIP: You can select the action key to adjust the scale.

2Change your direction until the bearing indicator is aligned with the painted mark at the top of watch bezel to move toward your next waypoint.

TIP: If the to-and-from indicator points opposite the course line pointer, you are moving away from your next waypoint.

3Continue toward your next waypoint.

The course deviation indicator moves toward the course line pointer. When the course deviation indicator is fully aligned with the course line pointer, you are on the selected course to your next waypoint.

Calibrating the Compass

NOTICE

Calibrate the electronic compass outdoors. To improve heading accuracy, do not stand near objects that influence magnetic fields, such as vehicles, buildings, and overhead power lines.

Your device was already calibrated at the factory, and the device uses automatic calibration by default. If you experience irregular compass behavior, for example, after moving long distances or after extreme temperature changes, you can manually calibrate the compass.

1Select the action key.

2Select Setup > Sensors > Compass > Calibrate > Start.

3 Follow the on-screen instructions.

Map

represents your location on the map. As you travel, the icon moves and leaves a track log (trail). Waypoint names and symbols appear on the map. When you are navigating to a destination, your route is marked with a line on the map.

Altimeter and Barometer

The device contains an internal altimeter and barometer.

•On Demand sensor data (Viewing the Data Pages)

•Always On sensor data (Turning on a Sensor Mode)

•Altimeter settings (Altimeter Settings)

•Altimeter and barometric readings (Altimeter and Barometric Readings)

Calibrating the Barometric Altimeter

Your device was already calibrated at the factory, and the device uses automatic calibration at your GPS starting point by default. You can manually calibrate the barometric altimeter if you know the correct elevation or the correct sea level pressure.

1Select the action key.

2Select Setup > Sensors > Altimeter.

3 Select an option:

•Select Auto Cal. > At Start to calibrate automatically from your GPS starting point.

•Select Auto Cal. > Continuous to calibrate automatically with periodic GPS calibration updates.

•Select Calibrate to enter the current elevation or sea- level pressure.

Tracking Weather Changes Overnight

You can use your device to track changes in barometric pressure over time. Increases in barometric pressure usually indicate good weather, and decreases in barometric pressure usually indicate bad weather.

1Select the action key.

2Select Setup > Sensors > Mode > Always On.

3Select repeatedly to return to the time of day page.

4Select repeatedly until the barometric data page appears.

The current barometric pressure appears in large numbers, and the range of previous readings for the graph shown appears in small numbers at the bottom of the page.

5Compare the current reading with earlier readings to see if the barometric pressure is increasing or decreasing.
