INSTRUCTIONS FOR BATTERIES AND RECHARGE-
ABLE BATTERIES
- Batteries/rechargeable batteries do not belong in the hands of children.
- Do not leave batteries/rechargeable batteries lying around; there is a risk that
they could be swallowed by children or pets. If swallowed, consult a doctor im-
mediately.
- Leaking or damaged batteries/rechargeable batteries in contact with the skin
can cause acid burns, therefore, use suitable protective gloves.
- Batteries/rechargeable batteries must not be short-circuited, opened or thrown
into a fi re. 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 suitable
rechargeable battery chargers.
- Make sure that the polarity is correct when inserting the batteries/rechargeable
batteries (pay attention to the negative and positive terminals).
FEATURES
- Snooze function (repeated alarm)
- Crescendo alarm
- Clock face light
INSERTING/REPLACING THE BATTERY/RECHARGE-
ABLE BATTERY
Open the battery compartment on the housing's back side and insert a battery of
the type AA/Mignon while observing the correct polarity. The correct polarity is
indicated in the battery compartment.
After inserting the battery, the clock hands move to the reception position (12.00 am,
04.00 am or 08.00 am), and the radio-controlled alarm clock performs a reception
attempt for the DCF signal (see chapter "DCF reception").
Close the battery compartment again.
The battery needs changing when the clock stops.
 
A rechargeable battery may be used, but due to the lower voltage output
(rechargeable battery = 1.2V, standard battery = 1.5V) and the lower capac-
ity, the service life is shorter.
DCF RECEPTION
Immediately after the battery is inserted, the device makes the fi rst attempt to receive
the DCF signal. The hands of the clock run to the receiver position and automatically
set themselves to the current time after successfully receiving the DCF signal.
 
The recognition and interpretation of the DCF signal can take 2-5 minutes.
Do not move the clock during this time. Do not press any buttons or switch-
es!
Bad reception can be caused, for example, by metalized insulated glass, rein-
forced concrete buildings, coated special wallpapers, proximity to electronic
devices, or installation in cellars.
If the clock hands do not move to the current time after 10 minutes, change
the position of the radio-controlled alarm clock and press the RESET button
on the rear of the housing by using a sharp object.
This will start a new reception attempt.
The reception attempt for the daily automatic synchronisation with the DCF time is
done several times a day. One successful reception per day is suffi cient to keep the
deviation to less than one second.
The DCF signal is encoded and transmitted via a
DCF transmitter in Mainfl ingen (near Frankfurt). Its
range is up to 1,500 km and, under ideal reception
conditions, even up to 2,000 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 manu-
ally setting summer and winter time.
MAKING A DCF RECEPTION ATTEMPT
To perform a manual search for the DCF-signal (e.g. if you have placed the radio-
controlled alarm clock to a different location), press the RESET contact on the hous-
ing's rear by using an electrically conductive object (e.g. a small screw driver). For
this purpose, insert the screw driver in the opening labelled with RESET at the back
of the housing until you hear an acoustic signal.
This will start a new reception attempt. Then, as described above, wait about 2-5
minutes until the correct time is displayed.
