F.Weather measurement units (°F/°C, inHg/hPa)

1.Press and hold the “SET” button for 1 second.

2.Press and release the “SET” button 11 times.

3.The selected temperature units will now flash (°F default/factory setting).

4.Press and release the “+”or “–“button to select °F (Fahrenheit) or °C (Celsius).

5.Press and release the “SET” button to advance to the barometric air pressure units setting.

6.The selected air pressure units will now flash (inHg default/factory setting).

7.Press and release the “+”or “–“button to select inHg (inches of Mercury) or hPa (hectopascal or millibars).

8.Press and release the “SET” button to advance to the barometric air pressure calibration setting.

9.The air pressure reading will now flash (29.91 inHg, 1012.8 hPa as default).

10.Press and release the “+”or “–“button to adjust to the correct relative air pressure based on local reports.

11.Press and release the “SET” button to advance to the forecast sensitivity setting.

Note: Barometric air pressure is usually reported as “relative air pressure”. This reading is based on the combination of absolute air pressure and altitude. In general, an increase in altitude will result in a decrease in air pressure. Relative air pressure will make readings in nearby locations relative to each other to allow for proper forecasting. The absolute air pressure reading in the Weather Center cannot be calibrated, only the relative air pressure.

12.The selected forecast sensitivity setting will now flash (0.09 inHg default).

13.Press and release the “+”or “–“button to select 0.06, 0.09, or 0.12 inHg (if hPa is selected, the choices will be 2, 3, or 4). A lower setting will result in a quicker change in the forecast icon. In other words, if the setting is 0.06 inHg, the forecast icon will change if the air pressure changes by at least 0.06 inHg within a six-hour period. This is useful, as certain areas will have a change of air pressure but no change in weather.

14.Press and release the “SET” button to advance to the storm warning setting.

15.The selected storm warning level will now flash (0.15 inHg, 5 hPa default).
