10. DCF reception

The weather station can receive and evaluate the so-called DCF signal.
This is a signal which is sent by a transmitter in Mainflingen (near
Frankfurt am Main). Its range is up to 1500 km. With ideal transmission
conditions even up to 2000 km.
Among other things, the DCF signal includes the precise time (theoretical
deviation of 1 second in a million years!) and the date.
This means you do not have to switch manually between daylight
savings time and normal time.
The first DCF reception attempt is always performed when commissioning
the device (inserting the battery, see chapter 9).

The detection of the DCF signal and its evaluation may take a few minutes. Once you have found a good
reception position, do not move the weather station any more during this time. Do not press any buttons
on the weather station.
Do not place the weather station next to electric/electronic devices; do not place it near cables, wall
outlets or metal parts.
A bad reception can also be caused by, e.g. metallised insulated glass windows, reinforced concrete
constructions, coated special wallpaper or installation in basements.
Automatic synchronisation takes place every day at approx. 0:00 hrs, 3:00 hrs, 6:00 hrs and 12:00 hrs. A single
reception per day is sufficient to keep the daily precision deviation below 1 second.

It is also possible to enter the time and date manually in case of difficult reception positions.
You can start a DCF signal reception attempt manually as well by keeping the button " " (7) depressed
until the DCF radio tower symbol starts to blink (see chapter 9. d).
