Radio signal (DCF):
The DCF signal (time signal transmitter) consists of time pulses emitted by one of the most accurate clocks in the
world close to Frankfurt /Main, Germany.
In ideal conditions, your weather station can pick up this signal over a distance of up to approx. 2000 km around
Frankfurt / Main. Reception of the radio signal generally takes approx. 3–10 minutes.
Reception can be considerably impaired by obstacles (e.g. concrete walls) or sources of interference (e.g. other
electrical devices). In the event of reception problems, change the position of the weather station (e.g. to somewhere
near a window).
Operation
Receiving the DCF radio time signal
After a connection with the outdoor sensor is established or 3 minutes after the batteries are installed, the weather
station automatically begins to search for the DCF radio signal. The search is shown in the LC display by the radio
tower symbol (5) flashing.
Note: In buildings made of reinforced concrete the reception of the radio signal may be severely impaired (see
"Setting up the devices").
In order to correct any deviations from the exact time, the clock is automatically synchronized with the DCF radio
signal every day at 1:00, 2:00 and 3:00.
Reception of the DCF radio signal can also be started manually on the weather station.
Press the + and – button (35), (36) at the same time. The weather station attempts to receive the DCF radio signal.
