Station to collect air pressure data at a constant altitude and therefore result in an 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 upper floors of a house remove the batteries from both the Weather Station and transmitter and re insert them after about 30 seconds By doing this the Weather Station will not mistake the new location as being a possible change in air pressure when really it is due to the slight change of altitude Again disregard weather forecasts for the next 12 to 24 hours as this will allow time for operation at a constant altitude The weather tendency indicator Working together with the weather icons are the weather tendency indicators located above and below the weather icons When the indicator points upwards it means that the air pressure is increasing and the weather is expected to improve but when indicator points downwards the air pressure is dro
