First, insert the batteries in the transmitter (see "How to install and replace batteries in the Temperature Transmitter" below). 2. Within 2 minutes of powering up the transmitter, insert the batteries in the Temperature 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 the indoor temperature/humidity and the time as 0:00 will be displayed. If these information are not displayed on the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once the indoor data is displayed user may proceed to the next step. 3. After the batteries are inserted, the Weather station will start receiving data signal from the transmitter. The outdoor temperature data should then be displayed on the Weather station. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1. 4. In order to ensure sufficient 868 MHz transmission however, the distance between the Weather Station and the transmitter should not be more than 100 meters (see notes on "Positioning" and "868 MHz Reception"). Note: In the event of changing batteries of the units, ensure the batteries do not spring free from the contacts. Always wait at least 1 minute after removing the batteries before reinserting, otherwise start up and transmission problems may occur. WHEN MORE THAN ONE TRANSMITTER IS USED 1.

Following the indoor temperature/humidity and the time as 0:00 will be displayed. If these information are not displayed on the LCD after 60 seconds, remove the batteries from both units and wait for at least 60 seconds before reinserting them. The outdoor temperature data from the first transmitter (channel 1) should then be displayed on the Weather Station. Also, the signal reception icon will be displayed. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1. Insert the batteries in the second transmitter as soon as the outdoor temperature readings from the first transmitter are displayed on the Weather Station. Note : User shall insert the batteries into the second transmitter within 45 seconds after the Weather Station displays the information of the first transmitter. The outdoor temperature from the second transmitter and the "channel 2" icon should then be displayed on the Weather Station. If this does not happen after 2 minutes, the batteries will need to be removed from all the units and reset from step 1. Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the Weather Station. Then within 2 minutes, the channel 3 outdoor data from the third transmitter will be displayed and the channel icon will shift back to "1" once the third transmitter is successfully received. If this is not happen, user shall restart the setting up from step 1. Note : User shall insert the batteries into the third transmitter within 45 seconds after the Weather Station displays the information of the first transmitter. Or immediately after reception of the second transmitter is finished. In order to ensure sufficient 868 MHz transmission however, the distance between the Weather Station and the transmitter should not be more than 100 meters (see notes on "Positioning" and "868 MHz Reception"). 32 IMPORTANT: Transmission problems will arise if the setting for additional sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all units and start again the set-up from step 1. HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION The Weather Station uses 2 x AA, IEC LR6, 1.5V batteries. If the batteries need to be replaced, the low battery symbol will appear on the LCD. To install and replace the batteries, please follow the steps below: 1. Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover. 2. Insert batteries observing the correct polarity (see marking). 3. Replace compartment cover. HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER The Temperature Transmitter uses 2 x AA, IECLR6, 1.5V batteries. To install and replace the batteries, please follow the steps below: 1. Slide the battery cover downwards and remove. 2. Insert the batteries, observing the correct polarity (see marking). 3. Replace the battery cover. 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 33 the Weather Station in the first three 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. Return used batteries to an authorized depot. FUNCTION KEYS: Weather Station: The weather station has four easy to use function keys.

On the other hand, the short blinking of the icon shows that a reception is currently taking place. 36 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 1500km radius of Frankfurt. Once the outdoor temperature is displayed on the Weather station, 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. DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at 02:00 am, then the next reception takes place the next hour and so on until 06:00am, or until the reception is successful. If the reception is not successful at 06:00 am, then the next attempt will take place the next day at 02:00 am. 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 meters. · 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. · During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second. 37 MANUAL SETTINGS The following manual settings can be changed when pressing the SET key for: · LCD contrast setting · Time zone setting · Time reception ON/OFF setting · 12/24-Hour setting · Manual time setting · Calendar setting · Snooze setting · °C/°F setting · Weather forecasting icon sensitivity setting LCD CONTRAST SETTING: LCD (flashing) The LCD contrast can be set to 8 different levels to suit the users needs (default LCD contrast setting is LCD 5).
