level pressure display. Press and hold the Pressure/Altitude key to enter the sea level
pressure adjusting mode. Use the UP or DOWN key to enter sea level pressure and use
Pressure/Altitude to confirm. The atmospheric pressure can be displayed in mb/hPa
or inHg. To change the pressure unit, press and hold the Unit key at sea level pressure
display and use UP or Down key to select. Press the Unit key to confirm.
If you want to check the pressure history for a particular hour during the past 36 hours,
