SET THE SEA-LEVEL PRESSURE
Sea level pressure can change relative to location. To achieve
accurate altitude readings, set the sea-level pressure value
before every trip. Check the newspaper, local news station,
trail marker, or weather forecast for local readings, and always
select the reading nearest to your present location.
The altitude reading will change according to the sea
level pressure adjustment.
VIEW THE SEA-LEVEL PRESSURE
To view a graphical image of the current sea
level pressure reading, press FUNC/SET with
the SEA screen shown in ALTI-BARO Mode.
Press again to return to normal display.
