6.3 Reception of the DCF frequency signal
• After the reception of the outdoor values, the clock will now scan the DCF frequency signal and the DCF symbol flashes on
the display.
• When the time code is successfully received after 3-10 minutes, the radio-controlled time and the DCF symbol will be
shown steadily on the display.
• The DCF reception always takes place at 1:00 and 2:00 o'clock in the morning. If the reception is not successfully received
at 3:00 o'clock, further attempts will be taken at 4:00 and 5:00 o'clock.
• You can also activate the DCF reception manually.
• Press the SEARCH button.
• The DCF reception symbol flashes.
• There are three different reception states:
flashing – reception is active
solid – reception is very good
no symbol – no DCF reception / reception deactivated
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually.
• The clock will then work as a normal quartz clock. (see: Manual settings).
6.4 Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt
based in Braunschweig (Brunswick), Germany. 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 the frequency signal DCF-77 (77.5 kHz) and has a transmitting
range of approximately 1,500 km. Your radio clock receives the signal, converts it and always shows the exact time. T
he adjustment to Daylight Saving Time (summer/winter time) is automatic. In Daylight Saving Time DST is shown on the dis-
play. The reception quality depends mainly on geographic location. Normally there should be no reception problems within a
1,500 km radius around Frankfurt.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like computer screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the received signal is naturally weakened. In extreme cases,
please place the unit close to a window to improve reception.

• During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily
reception is adequate to keep the accuracy deviation under 1 second.
7. Backlight
• Attention: Continuous illuminated backlight only works when using the power adapter.
• Default for the backlight is HI.
• Press LIGHT (HI-LOW-OFF) button once (LOW) to dim the backlight.
• Press LIGHT (HI-LOW-OFF) button once more (OFF) to turn off the backlight.
• To temporarily activate the backlight, press any button (in battery operation only).
8. Operation
• Press the LIGHT button to quit the setting mode. The device will automatically quit the setting mode if no button is pressed
for a few seconds.
• Press and hold the + or – button in setting mode for fast mode.
8.1 Manual settings
• Press and hold the SET button in normal mode for three seconds to enter the setting mode.
• DEUTSCH (default) flashes on the display.
• Adjust the desired language with the + or – button.
• If you select English, the display will now appear in English.
• Press the SET button again to do the settings in the following sequence: the button tone (BEEP ON - default), DCF recep-
tion (ATOMIC ON - default), the time zone (DCF 00H - default), the 12 or 24 hours system (FORMAT 24Hr - default), the
hours, the minutes, the year, the month, the date, the temperature unit (TEMP °C - default), the atmospheric pressure unit
(PRESSURE HPA - default) and the atmospheric pressure value (1013 hPa - default). Press the + or –button to adjust it.
• Confirm the setting with the SET button.
• Once the DCF time signal is successfully received and the DCF reception is activated (DCF ON), the manually set time is
overwritten.
8.1.1 Day-of-week language setting
• In the setting mode you can choose the day-of-the-week language.
