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: 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. enter
2. Insert batteries observing the correct polarity (see marking).
3. Replace compartment cover.
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. 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.
39

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
authorized depot.
SETTING UP :
When one transmitter is used
1. First, insert the batteries into the Temperature transmitter. (see “Install and replace batteries in
the Temperature transmitter“).
2. Immediately after and within 45 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
the LCD will light up briefly. Following the time as 0:00 and the indoor temperature and humidity
40

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 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.
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
41

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 theWeather 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
43

(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.

reception icon will be switched on. (If not successful, the icon will not be shown on the LCD). User can
therefore easily see whether the last reception was successful (“ON” icon) or not (“OFF” icon). On the
other hand, the short blinking of the icon shows that a reception is being done at that time.
