easy-to-read display and is simple to use with
the help of just a few buttons.
t is particularly accurate as it synchronises
itself daily with the radio time signal received
from the world's most precise transmitter. The
clock changes automatically from summer to
winter time and vice versa.
We hope you will be entirely satisfied with your
purchase.

• Never expose the alarm clock to severe tem-
perature fluctuations, moisture, direct sun-
light, dust or impacts.

How a radio-controlled
alarm clock works
The exact time is received from the official
German transmitter DCF77. The transmitter is
located in Mainflingen, near Frankfurt on Main.
The signal is transmitted on long wave at
77.5 kHz in a radius of approx. 1,500 km
(900 miles).
The alarm clock receives and sets the time
automatically using its built-in antenna. Once
the time is set, the alarm clock continues
operating on its quartz movement. The clock's
receiver system switches on daily and com-
pares the received time to the time displayed.
The alarm clock is highly accurate, meaning
that it will display the correct time even if the
clock is occasionally unable to receive the time
signal.

12
Prior to first use
Remove the protective film from the
display.
Inserting/replacing batteries
1. Slide the battery com-
partment lid downwards
and lift it up.
2. nsert batteries or
replace batteries.
Ensure correct posi-
tioning of the poles
(+/–).
m

13
All display indicators appear briefly and the
alarm clock switches to reception.
The radio reception symbol flashes in the
upper right of the display.
3. Replace the battery compartment lid and
slide it upwards as far as it will go. You
should hear and feel it click into place.
• A change of battery is necessary when the
battery symbol appears in the display.
• Changing the batteries deletes all settings.

14
Radio signal reception
The alarm clock attempts to receive the radio
signal for several minutes. f it does not
receive an adequate signal during this time,
the reception indicator will switch itself off and
the clock will start running from the time of
day set so far. n this case, refer to the section
“ nformation about the location and possible
sources of interference”.
After receiving the time signal, the reception
indicator is constantly displayed.

15
Reception indicators and their
meaning
The quality of the last signal received
was satisfactory, and the time of day
has been synchronised with the recep-
tion signal.
Weak radio signal.
Reception of the transmitter was not
possible or the time of day was set
manually and not synchronised with
the transmitter.
The reception system of the clock checks the
received time at regular intervals and synchro-
nises it with the time displayed on the clock.

16
Please note:
• f adequate reception is not possible, the
reception indicator in the display will switch
off after a few minutes and the time will con-
tinue to run normally as set before.
• f reception is adequate, the clock will be set
to DCF77 time. Any settings made before-
hand will be automatically adapted.

17
Information regarding the location
and possible sources of interference
• We recommend placing the alarm clock near
to a window.
• Do not place the alarm clock on or near metal
surfaces.
• Allow a distance of at least two metres from
sources of interference, for example televi-
sion sets, computers, etc. Airports, base-
ments and high-rise buildings, etc. are not
good reception locations.
• Undisturbed reception is not possible in
moving vehicles such as cars or trains.
• The transmitter may shut off temporarily.
• Disturbances may occur during thunder-
storms.
