Radio-controlled clock with temperature
5. Operating elements:
• Button "SNZ"
• Button "SET"
• Button "ALARM"
• Button "UP"
• Button "DOWN"
• Button "WAVE"
6. Getting started
• Open the battery compartment and remove the insulation strip.
• A brief beep tone will sound and all LCD segments will light up for about 2 seconds.
• Close the battery compartment again.
• Remove the protective foil.
• The clock will scan the DCF frequency signal and the DCF symbol flashes on the LCD. When the signal is received
successfully after 3-5 minutes, the radio-controlled time and the DCF symbol appear permanently.
• Manual initialization can be helpful. Press WAVE button.
• In case 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 clock and calendar).
Radio-controlled time reception:
The time base for the radio-controlled time is a Caesium Atomic Clock operated by the Physikalisch Technische Bundes-
anstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and
transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled clock receives this signal and converts it to show the precise time in sum-
mer or wintertime. The quality of the reception depends greatly on the geographic location. In normal cases, 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 a minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme
cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter.
• During night-time, the atmospheric disturbances are usually less severe and reception is possible in most cases. A sin-
gle daily reception is adequate to keep the accuracy deviation below 1 second.
• The radio-controlled clock receives the signals always between 1.00 and 4.00 am.
7. Operation
• Important: Buttons will not function while scanning DCF signal.
• The instrument will quit the setting mode, if there is no button used within 30 seconds.
• Holding "UP" or "DOWN" buttons in setting mode, you will enter fast mode.
7.1 Manual setting of clock and calendar
• Hold "SET" button for 3 seconds to enter setting mode. The year indicator is flashing.

sequence is shown as follows:
Year, Day, Day-of-week language,12 or 24 hours mode, time zone, hours, minutes.

Radio-controlled clock with temperature
• Day-of-week language: German (GE), English (EN), French (FR), Italian (IT), Spanish (ES), Dutch (NE), Danish (DA).
• The time zone is used for the countries where the DCF signal can be received but the time zone is different from
the German time (e.g. + 1=one hour later).
7.2 Alarm clock function
• Hold "ALARM" button for 3 seconds to enter alarm setting mode. A1 (alarm 1) appears on the display. The hour
digits are flashing. Press "UP" or "DOWN" button to adjust the hours. Confirm with "ALARM" button. Set minutes
in the same way.
• Confirm with "ALARM" button. A2 (alarm 2) appears on the display. The hour digits are flashing. Press "UP" or
"DOWN" button to adjust the hours. Confirm with "ALARM" button. Set minutes in the same way.
• To switch on the alarm signal select your desired alarm by "ALARM" button: A1 or A2 appears. Press "UP" to acti-
vate or deactivate the alarm function in the respective alarm mode. The alarm symbol SNZ1 and/or SNZ2 appears
or disappears on the display.
• Once the alarm starts to ring, you can stop the alarm by pressing any button.
• Activate the snooze function by pressing the "SNZ" button. The alarm will be interrupted for 5 minutes.
