For accurate barometric pressure trends, the weather 

station should operate at the same altitude for recordings 

(i.e. it should not be moved from the ground to the second 

floor of the house). When the unit is moved to a new 

location, discard readings for the next 12 hours and 

correct the height adjustment if needed   

Wrong temperature 

 

Check whether the sensor is exposed to direct sunlight.

Care and maintenance   

 

 

Read carefully the manual before using this product. 

 

Do not expose the main unit to direct sunlight, extreme cold and moisture, and sudden changes in 

temperature. This would reduce the accuracy of detection. 

 

Do not place the product in locations prone to vibration and shocks 

– these may cause damage. 

 

Do not expose the product to excessive force, impacts, dust, high temperatures or humidity - these may 

cause malfunction, shorter battery life, damage to batteries and deformation of plastic parts.
