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.
