6. Getting started

• Open the battery compartment and insert a new bat-

tery (1,5 V AA), ensure battery polarity is correct.

• A brief beep tone will sound.
• The unit is ready for use.
• The pointers move to 12 o’clock and the clock is trying

to receive the radio signal for 3 - 12 minutes.

• When the time code is received, the radio-controlled

time will be shown.

• Twelve times a day the clock receives the radio signal.
• Manual initialization can be helpful. Press and hold REC

button for 3 seconds. The pointers move to 12 o’clock
and the clock will scan the DCF frequency signal again.

• If the clock cannot detect the DCF-signal (for example

due to disturbances, transmitting distance, etc.), the
time can be set manually. The clock will then work as a
normal quartz clock. (see: Manual setting of the clock).

6.1 Radio-controlled time reception

he time base for the radio-controlled time is a caesium
atomic clock operated by the Physikalisch Technische Bun-
desanstalt Braunschweig. It has a time deviation of less
than one second in one million years. The time is coded
and transmitted from Mainflingen near Frankfurt via fre-
quency signal DCF-77 (77.5 kHz) and has a transmitting

Radio-controlled alarm clock

range of approximately 1,500 km. Changeover from sum-
mer time or winter time is automatic. The quality of the
reception depends mainly on the geographic location.
Normally there should be no reception problems within a
1,500 km radius around Frankfurt.

Please take note of the following:

• Recommended distance to any interfering sources like

computer monitors or TV sets is at least 1.5 - 2 metres.

• Inside ferro-concrete rooms (basements, superstruc-

tures), the received signal is naturally weakened. In
extreme cases, please place the unit close to a window
to improve the reception.

• During nighttime, the atmospheric interference is usu-

ally less severe and reception is possible in most cases. A
single daily reception is adequate to keep the accuracy
deviation below 1 second.

7. Operation

• Press and hold the M.SET button to enter the fast

count.

• The instrument will automatically quit the setting

mode if no button is pressed within 8 seconds.

7.1 Manual setting of the time

• Press and hold M.SET button for three seconds.
• The second pointer does not move anymore.
• Hold the button until the desired time is indicated.
• Press the button briefly the pointer moves minute by

minute.

• After the setting the second pointer is moving forward

again.

• The manually set time will be overwritten by the DCF

time when the signal is received successfully

7.2 Setting of the alarm time

• Turn the dial for the alarm time and set your respective

alarm time (in direction of the arrow).

• To activate the alarm function, move the alarm switch

upwards (ON).

• When the alarm time is reached, the alarm will ring for

2 minutes.

• If it is not stopped, the alarm will automatically turn off

after 2 minutes and will be reactivated at the same
time.

• When the alarm rings, press SNOOZE/LIGHT button and

the snooze function is activated. The backlight turns on
for a short time.

• The alarm will be interrupted for 5 minutes.
• The snooze function can be activated up to seven

times.

• Move the alarm switch downwards (OFF), the alarm

function is deactivated.
