4.4 Examples of changing weather icons:
4.5 Storm warning indicator
The storm threshold can be set to suit the user’s requirement for storm forecasting
from 3-9hPa (default 4hPa). When there is a fall over pressure threshold within 3
hours, the storm forecasting will be activated, the clouds with rain icon and tendency
arrows will flash for 3 hours indicating the storm warning feature has been activated.
Notes to pressure sensitivity setting for weather forecasting:
The pressure threshold can be set to suit the user’s requirement for weather
forecasting from 2-4hPa (default 2hPa). For areas that experience frequent changes in
air pressure requires a higher setting compared to an area where the air pressure is
stagnant. For example if 4hPa is selected, then there must be a fall or rise in air
pressure of at least 4hPa before the weather station will register this as a change in
weather.
5. Program Mode
The base station has five keys for easy operation: SET key, ALARM key, MIN/MAX

- press the SET key to accept the change and advance to the next display mode.
