D UP KEY ( ) - Increases settings´ - Keep pressed: Changes the display Barometric pressure ­ Date (barometric pressure is not compensated at sea level) - Changes the display unit for the temperature display in degrees Celsius (°C) or degrees Fahrenheit (°F) E HOLDER FOR WALL HANGING For wall hanging F BATTERY COMPARTMENT For two batteries of the type UM-3 or `AA'. [. . . ] If no sensor signals are received within 2 minutes, [ ] then appears on the display. Press the [ ] key for 3 seconds to initiate a search for the signals of the external sensor. In this way, you can synchronise the receiving and transmitting signal between the outdoor sensor and the main appliance. Important: The external sensor must be set to channel 1. 2b) PREPARATION OF THE EXTERNAL THERMO/GYRO TRANSMITTER UNITS 1. Remove the cover of the battery compartment. Set channel 1 by moving the sliding switch (important: only set to channel 1!) 3. Insert the 2 batteries (1. 5 V, UM-3 or size `AA') in accordance with the respective polarities. Screw down the cover of the battery compartment again. 36 37 3. 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 Barometric increasing 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.
