•Wall mounting case (Mounting at a sheltered place. Avoid
direct rain and sunshine)
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 25 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 "Weather girl" icon will be displayed. If these are not displayed after 60
seconds, remove the batteries and wait for at least 10 seconds before reinserting
them.

53
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 weather girl icon 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.

54
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.
•And user may require to check the displayed readings on the weather station against

55
those shown on the transmitters in order to recognise the Channel No. of each
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”)
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. Remove the cover at the back of the
Weather Station.
56
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The Temperature 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 at the back of the
transmitter.
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 regularly to ensure optimum accuracy
of these units (Battery life See Specifications below).
57
Please participate in the preservation of the environment. Return used
batteries to an authorised depot.

*When the signal from the transmitter is successfully received by the Temperature Station,
this 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.
For better distinctness the LCD screen is split into 5 .

DCF-77 RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic Clock operated by the

64
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 1,500 km radius around Frankfurt.
Once the outdoor temperature is displayed on the Weather Station after initial set-up, 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.
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.
MANUAL SETTINGS:
The following manual settings can be done in the setting mode:

•LCD contrast setting
•Time zone setting
•Time reception ON/OFF setting
•12/24-Hour setting
•Manual time setting
•Calendar setting
