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, + key, ALARM key, HISTORY key and MIN/MAX

3. Wind speed / Gust speed (press the + key or MIN/MAX key shifts the display between the wind speed
and gust speed)
4. 1 hour/ 24 hour / week/ month / total rainfall quantity (press the + key or MIN/MAX key shifts the display
