First, insert the batteries into the Weather Station (see "How to install and replace batteries in the Weather Station" below). Once the batteries are in place, all segments of the LCD will light up briefly and a short signal tone will sound. Following some test data display, the indoor temperature and humidity, the time as 0:00 the date as 1.1. and the weather icons sun and clouds will be displayed. If the indoor temperature and humidity are not displayed after 30 seconds, remove the 26 2. 3. 4. 5. 6. batteries and wait for at least 10 seconds before reinserting them. Once the indoor data is displayed proceed to step 2. Within 3 minutes of activating the Weather station, place the batteries into the transmitter (see "How to install and replace batteries in the ThermoHygro outdoor transmitter" below). After inserting the batteries into the transmitter, the Weather station will start receiving data from the transmitter. The outdoor temperature and humidity should then be displayed on the Weather station. If this does not happen after 15 minutes, the batteries will need to be removed from both units and reset from step 1. The Weather station can take up to 3 remote transmitters. If you have purchased additional transmitters, follow step 2 for all extra transmitters. However, ensure that you leave 10 seconds in between the reception of the last transmitter and the set-up of the following transmitter. The Weather station will number the transmitters in the order of set-up, i.e. the first transmitter will have the temperature and humidity displayed with the number 1 against it and so on. After all the transmitters are set up, there is a testing period, during which the display switches quickly between all the received transmitters at random, according to which random transmission it receives. Pressing any key will stop this process. The process also stops automatically if up to 3 transmitters are received or no keys are pressed for a few minutes. Once the remote temperature and humidity have been received and displayed on the Weather station, the DCF-77 time code reception is automatically started. This takes typically between 3-5 minutes in good conditions. This time period is an excellent opportunity to locate the transmitter(s) in suitable location(s) outdoors. In order to ensure sufficient 433 MHz transmission however, this should under good conditions be no more than 100 meters from where the Weather station will be 27 7. finally positioned (see notes on "Positioning" and "433 MHz Reception"). If after 10 minutes, the DCF time has not been received, use the SET key to manually enter a time. The clock will automatically attempt to receive the DCF time at each full hour. When this 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 "Radio controlled Time Reception" and "Manual Time Setting"). HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION The Weather Station uses 2 x AA, IEC LR6, 1.5V batteries. When batteries will need to be replaced, the low battery icon will appear on the LCD. To install and replace the batteries, please follow the steps below : 1. Lift up the battery compartment and remove the cover. 2. Insert batteries observing the correct polarity (see marking). 3. Replace compartment cover. HOW TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO TRANSMITTER The Thermo-Hygro transmitter uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below: 1. Remove the battery cover. 2. Insert the batteries, observing the correct polarity (see marking). 3. Replace the battery cover on the unit. 28 Note : In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures : 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 on an annual basis to ensure optimum accuracy of these units. Please participate in the preservation of the environment.

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 1,500km radius around Frankfurt. Once the outdoor temperature and humidity are displayed on the Weather station after initial set-up, the DCF tower icon in the time display will start flashing in the upper left corner. This indicates that the weather station 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. ...
