Repeat this step whenever you find discrepancies between the reading shown on the main unit and that on the remote unit. 3a) WEATHER FORECAST The unit is capable of detecting atmospheric pressure changes. [. . . ] Based on collected data, it can predict the weather for the forthcoming 12 to 24 hours. 3b) BAROMETRIC PRESSURE TREND The atmospheric pressure indicator, in the weather forecast window, uses arrows to indicate if the atmospheric pressure is increasing, remaining stable, or decreasing. It is not necessary and not possible to adjust the altitude of the weather station. After the initial start-up of the weather station, a first forecast will be made within the first 24 hours of operation. In periods of long stable weather conditions, it becomes difficult to make a reliable forecast. The weather forecast is solely calculated on the basis of barometric air pressure changes. The probability of a correct weather forecast is approximately 70% and is valid for an area of approx. The forecast "Sunny" means at night "cloubless weather".
