TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The Weather Station uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:

TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER

The Temperature transmitter uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Insert finger or other solid object in the space at the bottom c of the battery compartment and lift up to remove the cover.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

1. Remove the battery compartment cover at the back of the outdoor temperature transmitter.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment 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 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).

SETTING UP :

When one transmitter is used

1. First, insert the batteries into the Temperature transmitter. (see “Install and replace batteries in

2. Immediately after and within 45 seconds, insert the batteries into Weather station (see “Install

Please participate in the preservation of the environment. Return used batteries to an authorized depot.

the Temperature transmitter“). and replace batteries in the Weather station”). Once the batteries are in place, all segments of

the LCD will light up briefly. Following the time as 0:00 and the indoor temperature and humidity

will be displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at least 10 seconds before reinserting them.

3. 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.

4. 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 “Positioning” and “868 MHz Reception”).

5. 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 35 minutes in good conditions. If after 10 minutes, the DCF time has not been received, press the SET key to manually enter a time initially.

When more than one transmitter is used

1. User shall remove all the batteries from the Weather station and transmitters and wait for 60

seconds if setting has been done with one transmitter before.

2. Insert the batteries to the first transmitter.

3. Within 25 seconds of powering up the first transmitter, insert the batteries to the Weather station.

Once the batteries are in place, all segments of the LCD will light up briefly. Following time as 0:00 and the indoor temp and humidity will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them.

4. The outdoor temperature 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.

5. Insert the batteries to 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 10 seconds of reception of the first transmitter.

6. The outdoor data from the second transmitter and the "channel 2" icon should then be displayed on

the Weather station. If this does not happen after 2 minute, the batteries will need to be removed from all the units and reset from step 1.

7. Insert the batteries to 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 10 seconds of reception of the second

transmitter.

8. 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 “Positioning” and “868 MHz Reception”).

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.

9. 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.

If after 10 minutes, the DCF time has not been received, press the SET key to manually enter a time initially.

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. 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”)

DCF 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 reception test period is completed, the DCF tower icon in the clock display will start flashing in the upper center. 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 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.
