dcF recePtion
Immediately after the battery is inserted, the device makes a first attempt
to receive the DCF signal. The hands of the clock run to the reception
position and automatically set themselves to the current time after suc-
cessfully receiving the DCF signal.
The reception attempt for the daily automatic
synchronisation with the DCF time is done
several times a day. One successful reception
per day is sufficient to keep the deviation to
less than one second.
The DCF signal is encoded and transmitted via
a DCF transmitter in Mainflingen (near Frank-
furt am Main). Its range is up to 1500 km and,
under ideal reception conditions, even up to
2000 km.
Among other things, the DCF signal includes the precise time (theoretical
deviation of one second in a million years!) and the date.
Naturally, this also eliminates the hassle of manually setting summer and
winter times.
Normal/rechargeable batteries do not belong in the hands of children.
Do not leave batteries/rechargeable batteries lying around; there is a
risk of them being swallowed by children or pets. If they are swallowed,
consult a doctor immediately.
Leaking or damaged batteries/rechargeable batteries in contact with
the skin can cause acid burns; therefore, use suitable safety gloves.
Batteries/rechargeable batteries must not be short-circuited, opened
or thrown into fire. There is a risk of explosion!
Do not recharge normal, non-rechargeable batteries; risk of explosion!
Only charge rechargeable batteries that are intended for this purpose;
use a suitable battery charger.
Make sure that the polarity is correct when inserting the battery/re-
chargeable battery (pay attention to plus/+ and minus/-).
Open the battery compartment on the back of the case and insert an
AA/Mignon battery, paying attention to the correct polarity.
The correct polarity is indicated on the battery compartment cover.
After inserting the battery, the clock hands move to the reception po-
sition (12.00 noon, 04.00 am or 08.00 am), and the radio alarm clock
starts to search for the DCF signal (see chapter "DCF reception").
Close the battery compartment again.
The battery needs to be replaced if the clock stops.
Rechargeable batteries can be used. However, the lower operat-
ing voltage (rechargeable battery = 1.2 V, battery 1.5 V) and lower
capacity will reduce the operating time.
The detection of the DCF signal and its evaluation lasts a few
minutes. Do not move the radio-controlled alarm clock during this
time. Do not press any buttons or switches!
Bad reception can occur, for example, by metallised insulated glass,
reinforced concrete buildings, coated special wallpapers, proximity
to electronic devices, or installation in cellars.
If after 10 minutes the hands have not moved to the current time,
change the location of the radio clock and remove the battery.
Insert the battery again after about one minute. This will start a
new reception attempt.
