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.
