Basic and manual settings

Automatic setting using the DCF signal
After the first time the base station is switched on and successful transmission is established between the base station and the measuring station, the clock will automatically search for aDCF signal. During the search, the wireless symbol (5) will flash.
When the radio signal is received, the date and time are automatically set.

Radio icon	Searching for the DCF signal
Flashing display	Active
Constant display	Successful – signal is being received
No display	Error – signal search ended

Note –Time settings

If, during initial setup of the device, a DCF radio signal is not received within the first few minutes, the search is aborted. The radio symbol disappears.
If there are reception problems, we recommend leaving the clock to sit overnight, since interference is generally less at night.
In the meantime, you can start a manual search for the DCF radio signal at another location or you can manually set the time and date.
The clock automatically continues to search for the DCF radio signal on a daily basis (2:00 a.m., 8:00 a.m., 2:00 p.m. and 8:00 p.m.). If the signal is received successfully, the manually set time and date are overwritten.
Press the RCC button (19) to start the manual search for the DCF radio signal.

Note –Manual search

The manual search is automatically aborted after 6-16 minutes.
Using the RCC button (19) frequently will drain the battery. We recommend only using this function to seek out an optimal location for the device.

Note –Summer time

The clock automatically switches to summer time. DST appears on the display as long as summer time is activated.

Manually setting

Press and hold the DISPLAYSET button (16) for approx. 3seconds to make the following settings one after the other:

Weather forecast

Based on changes in the atmospheric pressure and the data saved, the base station is able to make weather forecasts for the next 12 to 24 hours.

Note –Weather forecast

The weather forecast function is not available during the first few hours of operation because it requires data that is collected during operation.
The probability of an accurate weather forecast is around 70–75%.
The weather forecast and the current weather are indicated by four different symbols (6):

Maximum and minimum temperature and humidity values

The base station automatically stores the maximum and minimum indoor/outdoor temperature and humidity values.
Repeatedly press the MEM– button (17) to switch between the current temperature and humidity, minimum temperature and humidity (MIN) and maximum temperature and humidity (MAX).
