Signal strength indicator
The outdoor sensor can transmit data wirelessly over a range of approx. 150 m (line of sight). On some occasions,
the signal may be weakened or lost due to intermittent physical obstacles or other environmental interference. If
the sensor signal is lost in its entirety, you must reposition the weather station (the main unit) or the outdoor sensor.

b) DCF reception
The DCF time is automatically synchronised every day. This is suf-
ficient to keep the time accurate to within one second per day.
The DCF radio time signal is sent from a transmitter in Mainflingen
(near Frankfurt am Main, Germany). It has a range of up to 1500
km, increasing to 2000 km in ideal reception conditions. The DCF
signal contains information such as the exact time and date (with a
theoretical time deviation of one second every million years). There
is no need to set the summer and winter time manually.
• It may take a few minutes for the clock to receive a DCF signal. Do not move the weather station during that time.
Do not press any buttons or switches!
• Set the weather station up at least 1 m away from the power adapter.
•
Reception of the signal can be influenced by buildings in the vicinity as well as the precise geographical location.
• Poor DCF reception can occur, for example, due to metallised insulated glass, reinforced concrete buildings, coated
special wallpapers, metal panels, proximity to electronic devices or being in enclosed spaces such as cellars,
factory buildings and airports.
• During DCF reception, the LC display (8) darkens.
• If no current time is displayed, change the position of the weather station and attempt to receive the DCF signal
again.
