Batteries and Rechargeable Batteries
Batteries/rechargeable batteries must be kept out of reach of children.
Do not leave batteries/rechargeable batteries lying around; they could be swallowed by chil-
dren 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 protective gloves.
Batteries/rechargeable batteries must not be short-circuited, opened or thrown into ire. 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.
• Check that the polarity is correct when inserting the battery/rechargeable battery (pay atten-
tion to plus/+ and minus/-).
Features
• Snooze function (repeated alarm)
• Crescendo alarm
• Clock face light
• Seconds display on the LC display
Inserting/Replacing the Battery/Rechargeable Battery
• Open the battery compartment on the back of the case and insert a AA/Mignon battery,
paying attention to the correct polarity. The correct polarity is indicated in the battery compart-
ment.
• After inserting the battery, the clock hands move to the reception position (12:00 noon), and
the radio-controlled alarm clock starts to search for the DCF signal (see chapter “DCF recep-
tion”).
• Close the battery compartment.
• If the clock stops, replace the batteru.
Rechargeable batteries can be used. 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
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 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 the clock hands do not move to the current time after 10 minutes, change the posi-
tion of the radio-controlled alarm clock and press the RESET button on the rear of
the case using a sharp-pointed 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 suf
fi
cient to keep the deviation to less than
one second.
The DCF signal is encoded and transmitted via a DCF
1500 km
2000 km
transmitter in Main
fl
ingen (near Frankfurt am Main). Its
range is up to 1,500 km and, under ideal reception con-
ditions, even up to 2,000 km.
Among other things, the DCF signal includes the precise
time (theoretical deviation of 1 second in a million years!)
and the date.
Naturally, this also eliminates the hassle of manually set-
ting summer and winter time.
To Make a DCF Reception Attempt
• To perform a manual search for the DCF-signal (e.g. if you have placed the radio-controlled
alarm clock in a different location), press the RESET key on the rear of the case using a
sharp-pointed object.
• This will start a new reception attempt. Then, as described above, wait about 2-5 minutes
until the correct time is displayed.
Setting the Time Manually
It is necessary to set the time manually if the radio-controlled alarm clock is to be used beyond
the range of the DCF signal.
To set the time manually, press the M.SET button for 3 seconds.
• As soon as the minute hand starts to run, you can set the time manually.
• Press the M.SET button brie
fl
y, to adjust the time in minute steps, or keep the M.SET button
pressed, to adjust the time continuously.
• When the M.SET button is not pressed, the set time is automatically accepted and the
manual time setting mode is exited.
Starting DCF Signal Detection Manually
Use this function if, for instance, the automatic summer/winter time conversion was not
detected or the radio-controlled alarm clock has not received the DCF signal for a while.
The previously received DCF data is not deleted and the time resets itself to the time shown
previously, if the signal detection fails.
• To perform a manual search for the DCF signal, press the REC button for 3 seconds.
• The hands run to the receiving position (12:00) and the radio-controlled alarm clock tries to
detect the DCF signal.
• Wait for about 2-5 minutes, until the current time is indicated.
