*Barometric pressure readings are standardized to sea level. Elevation Range: -999’ to +15,000’;

-600 to + 4570 m. Note: The console screen limits display of lower elevation to -999’ when using feet as elevation unit. For elevations lower than -999’, use meters.

**This is the reduced value after standardizing to sea level.
