WEATHER FORECAST 3a) WEATHER FORECAST Based on the change in barometric pressure, the receiver unit calculates the weather development for the next 12-24 hours and indicates this with the following symbols: Symbols on the display Forecast Symbols on the display Forecast Rainy Strong rain Snow Sunny Slightly cloudy Clouded 3c) BAROMETRIC PRESSURE ­ TENDENCY DISPLAY The indicator for the barometric pressure tendency in the weather forecast window indicates the trend in barometric pressure change in the previous hour. Three different indicators are displayed: Indicator TREND TREND TREND increasing Barometric pressure trend staying the same falling 3b) PLEASE NOTE THE FOLLOWING: 1. When the weather station has been put into operation, it is not necessary to set the current barometric pressure. The appliance will calculate over the next few hours a weather forecast from the changes in barometric pressure. Lengthy, stable weather conditions make a weather forecast more difficult. A change in the weather symbol on the display may at times take longer than desired. The weather forecast is calculated solely by means of changes in the barometric pressure. The probability of the weather forecast is around 70% and applies for a radius of 20 ­ 30 kilometres. If the symbol `sunny' appears at night, this means cloudless weather. Fog is not displayed by the weather station as this can occur with different weather conditions. If you take the weather station with you on your travels, the weather forecast will alter due to the differences in height above sea level and the resulting changes in barometric pressure. Please wait up to 24 hours until the weather station has calculated the weather forecast based on the barometric pressure conditions at your new location. 41 Note: By default, the barometric pressure measured is displayed in 'mbar/hPa'.
