La Crosse Technology WIRELESS WEATHER STATION Instruction Manual page 25

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 upper floors of a house), remove the
batteries 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.
