T e Outdoor Temperature Transmitter
• Remote transmission of outdoor
temperature to Weather station by 868 MHz
signals
• Shower proof casing
• Wall mounting and table-standing
SETTING UP:
Note: T is weat er station receives only one outdoor transmitter.
1 First, insert the batteries into the Temperature transmitter (see “Install
and replace batteries in t e Temperature transmitter“)
2 Within 30 seconds, insert the batteries into Weather station (see “Install
and replace batteries in t e Weat er station”) Once the batteries are
in place, all segments of the LCD will light up briefly Then the time (as
0:00) and the weather icon will be displayed If these are not displayed
after 60 seconds, remove the batteries and wait for at least 30 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

27
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, 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
“Mounting” 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
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
(Please refer also to notes on “DCF-77 Radio Controlled Time” and “Manual
Time Setting”)
HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER
STATION
The Weather Station uses 2 x AA, IEC LR6, 1 5V batteries When batteries
need to be replaced, the low battery icon will appear on the LCD To install
and replace the batteries, please follow the steps below:

28
1 Lift up the battery compartment
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 AAA, IEC LR3, 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 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

29
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 t e preservation of t e environment.
Return used batteries to an aut orised depot.
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 1500 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
After the outdoor transmitter reception is completed in initial setup, the DCF
tower icon on the clock display will start flashing 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:

30
• 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

MANUAL TIME SETTING
In case the Weather station is not able to detect the radio-controlled time
(DCF time) signal (due to disturbances, transmitting distance, etc ), the time
can be manually set The clock will then work as a normal Quartz clock
flashing
