WIRELESS 868 MHz WEATHER STATION
Instruction Manual
INTRODUCTION:
Congratulations on purchasing this Weather station with wireless 868MHz transmission. It
not only displays the indoor temperature and humidity but also receives the outdoor
temperature. It is further acting as a DCF-77 radio controlled clock. With the totally 8
different weather icons featured by "Weather girl", users can easily observe the current
weather condition. And this innovative product is ideal for use in the home or office.

The Outdoor Temperature Sensor
• Remote transmission of outdoor temperature to Weather
Station by 868 MHz
• Weather-resistant casing
• Wall mounting case
• Mount in a sheltered place. Avoid direct rain and sunshine
SETTING UP:
1. First, insert the batteries into the temperature sensor. (see “Install and replace
batteries in the temperature sensor“).
2. Immediately after and within 30 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 and indoor temperature and humidity will be displayed. If
4

5
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 into the sensor, the Weather Station will start receiving
data from the sensor. The outdoor temperature and the signal reception icon should
then be displayed on the Weather Station. If this does not happen after 5 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 there should be no more than 330
feet (100 meters) between the final position of the Weather Station and the sensor
(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:
• The Weather Station will receive one outdoor sensor only.
• If after 10 minutes, the Atomic time (DCF time) signal has not been received, press the
SET key to manually enter a time initially.
• 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 Reception” and “Manual Time Setting”)
BATTERY INSTALLATION
INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses 2 x AA, IEC LR6, 1.5V Alkaline batteries. To install and replace
the batteries, please follow the steps below:
1. Remove the cover at the back of the Weather Station.
2. Insert batteries observing the correct polarity (see
marking).
3. Replace compartment cover.

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR

The temperature sensor uses 2 x AA, IEC LR6, 1.5V Alkaline battery.
To install and replace the batteries, please follow the steps below:
1. Pull out the battery holder at the bottom of the sensor.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery holder 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
sensor 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.

*When the outdoor signal is successfully received by the Weather Station, this icon will be
switched on. (If not successful, the icon will not be shown in LCD) So user can easily see
whether the last reception was successful (icon on) or not (icon off). On the other hand, the
short blinking of the icon shows that a reception is currently taking place.
For easy viewing, the LCD screen is divided into 3 sections displaying the information for
time and indoor data, weather forecast, and outdoor data.
Section 1 - OUTDOOR TEMPERATURE
• Display the current outdoor temperature.
• By pressing the MIN/ MAX key, display the stored MIN/MAX outdoor temperature,
with simultaneous display of MIN/ MAX icon.
• A signal reception symbol will be shown indicating that outdoor temperature signal
is received.
Section 2 - INDOOR DATA AND TEMPERATURE ICON (FEATURED BY WEATHER
GIRL)
• Display indoor temperature and indoor humidity
• The current temperature condition is displayed in form of one of eight icons,
featured by Weather girl, which change in appearance according to the current
outdoor temperature.

• Format of the weather girl icons refers to the below clause "Weather girl Icon"
Section 3 - TIME
• In normal mode, display the time and calendar.
• A signal reception symbol is shown indicating that Atomic time (DCF time) signal is
received.
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 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.

13
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 metres.
• 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:
• Time zone setting
• Manual time setting
• Calendar setting
• °C/ °F setting
Press and hold the SET key for about 3 seconds to advance to the setting mode:

TIME ZONE SETTING:
flashing
The time zone default of the Weather station is "0 hour". To change to another time zone:
1. Press and hold the SET key for about 3 seconds to enter the time zone setting
(flashing).
2. Using the + key, set the time zone. The range runs between 12 to -12 hr, in
consecutive 1hour intervals.
3. Press the SET key to confirm and enter the “Manual Time Setting” or exit the
setting mode by pressing the MIN/MAX key
MANUAL TIME SETTING
In case the Weather Station is not able to detect the Atomic time (DCF) signal
(disturbances, transmitting distance, etc.), the time can be manually set. The clock will then
work as a normal Quartz clock.
