How to switch between Units?
The watch can display altitude in meter(m) or feet(ft); the
watch can display temperature in degree Celsius(℃) or
degree Fahrenheit(℉).
To switch among different unit, press and hold the E button to
change the units following the adjacent units select sequence.
Why the Altitude need to be adjusted?
As the absolute altitude is calculated from air pressure, the
change of air pressure would affect the altitude reading.
To achieve a more accurate reading, the weather master
need to be calibrated from time to time as pressure may
change gradually even within hours.
