If these are not displayed after 60 seconds, remove the batteries and wait for at least 10 seconds before reinserting them. After inserting the batteries into the transmitter, the Temperature Station will start receiving data from the transmitter. The outdoor temperature and the signal reception icon should then be displayed on the Temperature Station. If this does not happen after 5 minutes, the batteries will need to be removed from both units and reset from step 1. In order to ensure sufficient 868 MHz transmission there should be no more than 330 feet (100 meters) between the final position of the Temperature Station and the transmitter (see notes on "Mounting" and "868 MHz Reception"). Once the remote temperature has been received and displayed on the Temperature station, the DCF time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good conditions. Note: · The Temperature Station will receive one outdoor transmitter only. · If after 10 minutes, the Atomic time (DCF time) signal has not been received, press the SET key to manually enter a time initially. · Daily DCF reception is done at 02:00 and 03:00 every day. If the reception at 03:00 is not successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at 06:00 is still not successful, then the next try takes place 39 at 02:00 next day.If reception is successful, the received time will override the manually set time. The date is also updated with the received time. (Please refer also to notes on "DCF Reception" and "Manual Time Setting") BATTERY INSTALLATION INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION The Temperature Station uses 2 x AA, IEC LR6, 1.5V Alkaline batteries.

(If not successful, the icon will not be shown in LCD) So user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is currently taking place. For easy viewing, the LCD screen is divided into 3 sections displaying the information for time and indoor data, weather forecast, and outdoor data. Section 1 - OUTDOOR TEMPERATURE Display the current outdoor temperature. By pressing the MIN/ MAX key, display the stored MIN/MAX outdoor temperature, with simultaneous display of MIN/ MAX icon. · A signal reception symbol will be shown indicating that outdoor temperature signal is received. · · Section 2 - INDOOR DATA AND TEMPERATURE ICON (FEATURED BY WEATHER GIRL) · Display indoor temperature and indoor humidity · The current temperature condition is displayed in form of one of eight icons, featured by Weather girl, which change in appearance according to the current outdoor temperature. 45 · Format of the weather girl icons refers to the below clause "Weather girl Icon" Section 3 - TIME AND CALENDAR · In normal mode, display the time and calendar. · A signal reception symbol is shown indicating that Atomic time (DCF time) signal is received. DCF-77 RADIO CONTROLLED TIME: The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio-controlled Temperature Station receives this signal and converts it to show the precise time in summer or wintertime. The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1,500 km radius around Frankfurt. Once the outdoor temperature is displayed on the Temperature Station after initial set-up, the DCF tower icon in the clock display will start flashing in the upper left corner. This indicates that the clock has detected that there is a radio signal present and is trying to 46 receive it. When the time code is received, the DCF tower becomes permanently lit and the time will be displayed. If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please take note of the following: · Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 metres. · Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter.
