Avoid direct rain and sunshine) SETTING UP: Note: This weather station receives only one outdoor transmitter. 1. 2. First, insert the batteries into the Temperature transmitter. (see "Install and replace batteries in the Temperature transmitter"). Immediately after and within 30 seconds, insert the batteries into Weather station (see "Install and replace batteries in the Weather station"). Once the batteries are in place, all segments of 40 3. 4. 5. the LCD will light up briefly. Following the time as 0:00 and the "Weather man" icon will be displayed. 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, the Weather station will start receiving data from the transmitter. The outdoor temperature and the signal reception icon should then be displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1. In order to ensure sufficient 868 MHz transmission however, this should under good conditions be a distance no more than 100 meters between the final position of the Weather Station and the transmitter (see notes on "Mounting" and "868 MHz Reception"). Once the remote temperature has been received and displayed on the Weather station, the DCF time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good conditions. Note: 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 at 02:00 next day. 41 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-77 Radio Controlled Time" and "Manual Time Setting") INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION The Weather station uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries, please follow the steps below: 1. Remove the cover at the back of the Weather station. 2. Insert batteries observing the correct polarity (see marking). 3. Replace compartment cover. 42 INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER The Temperature Transmitter uses 2 x AA, IEC LR6, 1.5V battery. To install and replace the batteries, please follow the steps below: 1. Remove the battery compartment cover at the back of the transmitter. 2. Insert the batteries, observing the correct polarity (see marking). 3. Replace the battery compartment cover on the unit. Note: In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a random security code is assigned by the transmitter at start-up and this code must be received and stored by the Weather station in the first 3 minutes of power being supplied to it. BATTERY CHANGE: It is recommended to replace the batteries in all units regularly to ensure optimum accuracy of these units (Battery life See Specifications below). Please participate in the preservation of the environment. Return used batteries to an authorised depot. 43 FUNCTION KEYS: Weather station: The weather station has four easy to use function keys.

(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). For better distinctness the LCD screen is split into 3 sections: Section 1 - OUTDOOR TEMPERATURE · Display the outdoor temperature. · Display the signal reception symbol indicating that receiver is receiving outdoor data Section 2 - INDOOR TEMPERATURE, INDOOR HUMIDITY, DATE AND WEATHER MAN ICON · Display the current indoor temperature and humidity in normal display. · Display the weather condition to be expected in form of 15 weather symbols (featured by Weather man) which change their appearance depending on the air pressure development and the current outdoor temperature. · Display the weather tendency indicator and indoor comfort level indicator · Display the date Section 3 - TIME · Display the current time. 47 · 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 Weather 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 Weather 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 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. 48 · 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.
