INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO TRANSMITTER
The Thermo-hygro 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.
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 on an annual basis to ensure optimum accuracy of these units.

8. 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”).
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.
RESETTING
The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following conditions occur:
•
Unsuccessful 868MHz signal reception.
•
Malfunction on the units.
•
Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute before powering up the Weather station again. Proceed
from step 1 in “Setting Up”.
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 data reception learning period is completed, 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 03:00 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.
