WIRELESS 433 MHz WEATHER STATION
Instruction Manual
INTRODUCTION:
Congratulations on purchasing this fancy Cubic Weather station
wireless 433MHz 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 and gives
colour-changing backlight.
With the totally 15 different weather forecast icons featured by
"weather man", users can easily observe the forecast weather
condition and will no longer worry the sudden weather change. This
innovative product is ideal for use in the home or office.

1. First, inse
station. Once the batteries are in place, all segments of the
LCD will light up briefly. Then the indoor temperature, the
weather man icon and the time as 0:00, will be displayed. If
the indoor temperature is not displayed after a few seconds,
remove the batteries and wait for at least 30 seconds before
reinserting them. Once the indoor data is displayed proceed to
step 2.
Within 45 seconds of activating the Weather station, place 2 x
AA, IEC LR6, 1.5V batteries into the transmitter.
3. After inserting the batteries into the transmitter, the weather
station will start receiving data from the transmitter. The
remote temperature will then be displayed on the station. If
this does not happen after 2 minutes, the batteries will need to
be removed from both units and reset from step 1.

Note:
When the transmitter is set up, there is a testing period. Then
DCF-77 time code reception is automatically starte
the clock is activated. This takes typically between 3 - 5
minutes in good conditions. This time period is an excellent
opportunity to locate the transmitter in suitable location
outdoors. In order to ensure sufficient 433 MHz transmission
however, this should under good conditions be no more than
25 meters from where the Weather station will be finally
positioned (see notes on “POSITIONING THE OUTDOOR
TRANSMITTER” and “433 MHZ RECEPTION”).
If after 10 minutes the DCF time has not been received, use
the MODE/ MIN key to manually enter a time
initially. The unit will still try and receive the time signal
regularly despite it being manually set. When it does receive
the signal, it will change the manually set time into the
received time.

operated by the Physikalisch Te
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 reception test period is completed, the DCF tower

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 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.
