•
All (rechargeable) batteries should be replaced at the same time. Mixing old and new
(rechargeable) batteries in the device can lead to (rechargeable) battery leakage and device
damage.
•
(Rechargeable) batteries must not be dismantled, short-circuited or thrown into fire. Never
recharge non-rechargeable batteries. There is a risk of explosion!

Operation
a) Inserting/changing the batteries
•
Insert the batteries before using the product for the first time. Change the batteries when the brightness of
the LCD display decreases significantly.
•
Remove the cover from the battery compartment (10).
•
Insert two 1.5 V/DC AAA batteries (included with the product) into the battery compartment. Ensure that
you observe the plus/+ and minus/- markings.
•
All symbols will appear on the LCD display and you will hear several beeps.
•
Replace the battery compartment cover.
You can operate the product with rechargeable batteries. However, rechargeable batteries have
a lower capacity and voltage (rechargeable battery = 1.2 V, conventional battery = 1.5 V),
therefore the battery life may be shorter. If you wish to use rechargeable batteries, always use
NiMH batteries with a low self-discharge. We recommend that you use high-quality alkaline
batteries for a longer battery life.
b) Setup
•
Place the radio alarm clock on a stable, horizontal surface.
•
Use suitable padding to protect the surfaces of valuable furniture against scratches.
•
To ensure optimal DCF reception, the radio alarm clock should not be placed next to other electronic
devices, cables or metal objects.
c)
Receiving a DCF signal
•
Once you have inserted the batteries, the alarm clock will automatically search for a DCF signal and the
DCF symbol will flash on the display.
•
It normally takes 3–5 minutes to receive a signal. Once a signal has been received, the DCF symbol and
the time will appear on the display
It takes a few minutes for the clock to detect and analyse the DCF signal. Do not move the alarm
clock during this time or press any buttons or switches.
Signal reception may be poor when the clock is near to double-glazed windows, reinforced
concrete, coated wallpapers or electronic devices, or when the clock is placed in a cellar.
If the time is not displayed after 5 minutes, move the radio alarm clock to another location and
try again. To search for a signal manually, press and hold the
°C/°F
button (6) for 3 seconds.
If a signal is not received, the radio symbol (
) will disappear from the display. Set the time
manually as described in "a) Setting the date and time".
