notes on batteries and rechargeable
batteries
-
Batteries/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 re-
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/rechargeable
battery (pay attention to plus/+ and minus/-).

inserting and rePlacing batteries/
rechargeable batteries
-
Open the battery compartment (1) on the back of the case and insert an AA/
Mignon battery, paying attention to the correct polarity.
-
The correct polarity is indicated at the battery compartment.
-
After inserting the battery, the clock hands move to the reception position
(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 (1).
-
The battery needs to be replaced if the clock stops.
The use of rechargeable batteries is possible. However, the lower operating
voltage (rechargeable battery = 1.2 V, battery 1.5 V) and lower capacity will
reduce the operating time.
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 automati-
cally set themselves to the current time after successfully receiving the DCF signal.
The detection of the DCF signal and its analysis 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, rein-
forced 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 alarm clock and remove the battery. After approx.
one minute insert the battery again. This will start a new reception attempt.
The DCF time is automatically synchronised every day. This is sufficient to keep the
deviation less than one second per day.
The DCF signal is encoded and transmitted via a DCF
transmitter in Mainflingen (near Frankfurt 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 pre-
cise time (theoretical deviation of one second in a
million years!) and the date.
Naturally, this also eliminates the hassle of manually
setting up summer and winter times.
