[. . . ] Use the DISPLAY key to toggle through the displays for other weather information: - Outdoor temperature/humidity - Outdoor wind chill - Outdoor dew point - Rainfall 24h - Rainfall 1h - Rainfall total. Notes to Dewpoint and Windchill: Air can at a certain temperature only carry a certain amount of water (water vapor), which also increases and decreases with temperature. If the air temperature decreases below the so called dewpoint (saturation point), the excessive water vapor will condense and fall out in form of dew, fog or rain. 15°C and a relative humidity of 50% the dewpoint will be about 5°C, at 80% humidity about 12°C. Windchill has been introduced for battle planning during World War II. It represents not the real measured but the one temperature a person feels in open area under the influence of wind and cold. Windchill is laid out in tables for various temperatures and wind speeds. 8°C and calm winds a person moving at a speed of 6 m/s will already feel a windchill temperature of 0°C. Wind Data (LCD Section 3) The current wind direction will be displayed on the LCD compass on the wind section. Press the WIND key to toggle between wind direction as numerical (e. g. SW) as well as numerical wind speed display inside the compass circle. 69 12. Operation keys The base station has 8 keys for easy operation. Please refer to the following table for use and function of each key: Further descriptions of the key functions with regard to their immediate range of application can be found in the Programming modes: SET - key - In normal mode to enter the manual basic programming mode - In basic programming mode to select the following setting modes: - LCD contrast setting - Manual time setting (hours/minutes) - 12/24 time format display - Calendar setting (year/month/date) - Time zone setting - °C/°F temperature setting - Wind speed unit setting - Rainfall unit setting - Pressure unit setting - Relative air pressure setting - Weather picture threshold setting - Storm warning setting - Acoustic storm alarm setting - In setting modes confirmation of the selected values - In alarm modes alarm ON/OFF - In alarm mode to enter programming of alarm values (long pressing) - To exit MIN/MAX modes - Toggle between Absolute and Relative air pressure displays - Toggle between the following current/ maximum/ minimum display modes: - Indoor temperature and humidity - Outdoor temperature and humidity - Outdoor wind chill - Outdoor dew point - Rainfall (24h, 1h, total) To toggle between the following settings: 70 PRESSURE key DISPLAY - key WIND - key ALARM - key - MIN/MAX - key PLUS(+) ­ key - MINUS(-) ­ key - Wind speed Wind direction Wind direction display in degrees In normal mode to enter the alarm programming mode In alarm programming mode to select the following setting modes: Time alarm setting Indoor temperature alarm (high & low) Outdoor temperature alarm (high & low) Indoor humidity alarm (high & low) Outdoor humidity alarm (high & low) Outdoor wind chill alarm (high & low) Outdoor dew point alarm (high & low) Rainfall alarm (24h, 1h) Pressure alarm (high & low) Wind speed alarm (high & low) Wind direction alarm In setting modes confirmation of the selected values To exit MIN/MAX modes To reset general alarm symbol In normal display mode to toggle between display of MIN/MAX values To toggle between MIN/MAX values in MIN/MAX mode To exit any programming mode In normal display mode to toggle between format of date display, seconds, time alarm and time zone To increase the values in the setting modes To exit MIN/MAX modes In normal display mode to re-enter data learning mode (long pressing for 2 seconds) In normal display mode to enable/disable the buzzer alarm (long pressing) To decrease the values in the setting modes In basic programming mode acoustic storm alarm ON/OFF 71 - To turn the alarms off 24 hours when the alarm is sounding - In MIN/MAX modes to resets recorded values and recorded dates and times * Press any key to activate the LCD Backlight 13. Basic Programming Modes Manual Setting modes The manual setting mode allows the user to change several basic settings, which is done by accessing one mode after the other simply by pressing the SET key. After the final mode, or if no key is pressed for 30 seconds, the manual setting returns to the normal display mode. Temperature display unit degree Celsius or Fahrenheit (default degree Celsius) 7. Wind speed display units in m/s, km/h, mph, Beaufort, knots (default setting km/h) 8. Relative air pressure setting from 920. 0 hPa ­ 1080. 0 hPa (default 1013. 0 hPa) 11. Weather forecast sensitivity setting 2 hPa ­ 4 hPa (default 4 hPa) 12. Acoustic storm alarm On/OFF (default ON) To change any of the above values, once your are in the setting mode, use the PLUS(+) or MINUS(-) keys to select the values followed by the SET key to enter the next setting. Continue to press the SET key to toggle through the setting mode until the LCD 72 returns to the normal display mode or press the MIN/MAX key at any time to exit. Keeping the PLUS(+) or MINUS(-) key depressed when setting certain units in the manual setting mode will increase/decrease digits in greater steps. Manual time setting The base station will continue to scan for the radio controlled time signal from 2am-6 am each day (winter time) or from 3am-6am (summer time) despite it being manually set. [. . . ] Broadband interferences in municipal areas can reach levels reducing the signal/noise ratio over the entire frequency band, thus also reducing the transmission distance. Devices working close by (example a neighbor's house) may also influence reception. Poorly shielded PCs can cause interferences that will reduce or in some cases stop reception Cleaning and Maintenance Clean the housing and screen of the base station only with a soft damp cloth. Ensure that the rain sensor does not collect leaves or other dirt by checking the funnel for blockages every now and then. [. . . ]
