that triggers a storm alert.
Sensor Mode: Sets the mode for the sensor. The

altitude, or the Barometer Only option when your

pressure.

• To enter the current elevation and sea level pressure
(optional), select Enter Manually.
• To calibrate automatically from the digital elevation
model, select Use DEM.
• To calibrate automatically from your GPS starting
point, select Use GPS.
Elevation Settings

manually.

you turn on GPS tracking.
