Radio-controlled clock (DCF77)
After inserting the batteries into the sensor, it will automatically scan for DCF77 signal for 6 minutes and the icon
is flashing.
If the DCF signal is found, the
icon is displayed on the sensor display and a blue LED is displayed at the DCF
icon on the weather station display.
If the signal is not found, press the WAVE button under the battery cover of the sensor.
The sensor will again search for the DCF signal.
The current data will then be synchronised daily between 2:00 and 3:00 am.
DCF77 radio signal propagates via radio waves (77.5 kHz) from a site near Frankfurt in Germany within a range of 1500
km. This radio time signal automatically takes into account summer and winter time, leap years and date changes.
In normal conditions (at a safe distance from sources of interference, such as television sets, computer monitors) the
capture of time signal takes several minutes.
If the sensor does not detect the signal, follow these steps:
1. Move the sensor to another location and try to capture the DCF signal again.
2. Check the distance between the sensor and sources of interference, such as computer monitors or television
sets. It should be at least 1.5 to 2 m during the reception of the signal. When receiving DCF signal, do not put the
sensor to the proximity of metal doors, window frames and other metal structures or objects (washing machines,
dryers, refrigerators etc.).
3. In reinforced concrete structures (cellars, high-rise buildings etc.), the DCF signal reception is weaker, depending
on the conditions.
Reception of the DCF 77 radio signal is affected by the following factors:
• thick walls and insulation, basements and cellars
• inadequate local geographical conditions (these are difficult to assess in advance
• atmospheric disturbances, thunderstorms
• appliances with no disturbance elimination
• television sets and computers placed near the DCF receiver
Indoor and outdoor temperatures
Indoor temperature is displayed at the IN icon.
Outdoor temperature is displayed at the OUT icon.

Weather forecast
The station forecasts weather on the basis of changes in atmospheric pressure for the next 12-24 hours. The accuracy
of weather forecasts is 70-75%. Neither the manufacturer nor the seller can be held responsible for any loss caused
by an incorrect forecast. When you first set or reset the weather station, it takes about 12 hours before the weather
station begins forecasting correctly.
