THE WEATHER FORECASTING ICONS:
There are 3 weather icons on the middle section of LCD 2, which can be displayed in any of the
following combinations:
SUNNY CLOUDY WITH SUNNY INTERVALS RAINY
For every sudden or significant change in the air pressure, the weather icons will update
accordingly to represent the change in weather. If the icons do not change, then it means either
the air pressure has not changed or the change has been too slow for the Weather Station to
register. However, if the icons displayed is a sun or raining cloud, there will be no change of
icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons
are already at their extremes.
The icons displayed forecasts the weather in terms of getting better or worse and not
necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy
and the rainy icon is displayed, it does not mean that the product is faulty because it is not
raining. It simply means that the air pressure has dropped and the weather is expected to get
worse but not necessarily rain.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours.
This will allow sufficient time for the Weather Station to collect air pressure data at a constant
altitude and therefore result in a more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather
forecasting feature is estimated to have an accuracy level of about 75% due to the varying
areas the Weather Station has been designed for use in. In areas that experience sudden
changes in weather (for example from sunny to rain), the Weather Station will be more
accurate compared to use in areas where the weather is stagnant most of the time (for
example mostly sunny).
If the Weather Station is moved to another location significantly higher or lower than its initial
standing point (for example from the ground floor to the first floor of a house), remove the
batteries and re-insert them after about 30 seconds. By doing this, the Weather Station will not
