WIRELESS WEATHER STATION 

C-8105 

USER’S INSTRUCTIONS 

 

The multifunctional weather station is equipped with many functions providing thorough weather information 
to you. The receiver unit has a clear, easy-to-read display that shows weather forecast, indoor temperature, 
relative humidity, pressure, moon phase, time and date, as well as the temperature and relative humidity 
measured and transmitted by the sensor. It is able to receive and display readings from up to 3 remote sensors. 
 
The receiver unit retains the minimum and maximum temperatures and relative humidity readings measured at 
various locations. The 433 MHz technology means no wire installation is required and you can place the 
sensors anywhere you like. 
 
With radio controlled function, the current time and date are automatically synchronized with the time signal 
transmitted from Frankfurt (DCF77). The signal can cover a distance of about 1500 km from the Frankfurt 
transmitter.
