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 ade-
quate to keep the accuracy deviation under 1 second.
7. Operation
7.1 Manual settings
• Important: The device cannot be operated during the DCF time-signal
reception.
• Press and hold the UP or DOWN button in setting mode for fast mode.
• The device will automatically quit the setting mode if no button is
pressed for 10 seconds.
7.1.1 Set mode
• Press and hold the SET button in normal mode for three seconds.
• d-1 (default) will be flashing. Press the UP or DOWN button to adjust
the display mode.
• Press the SET button to make the settings in the following sequence:
The automatic dimming function (A-of - default), the DCF reception
(dCF 1 - default), the hours, the minutes, the year, the month and the
day). Press the UP or DOWN button to adjust it.
• Confirm the setting with the SET button.
• Once the DCF time signal is successfully received and the DCF recep-
tion is activated (dCF 1), the manually set time is overwritten.
• An automatic DCF radio reception to update the time takes place daily at
2:00 and 3:00 o'clock in the morning. If the reception is not successfully
received at 3:00 o'clock, further attempts will be taken until 5:00 o'clock.
• Note: When the CR2032 battery is used up or not inserted, the DCF sig-
nal will be received automatically after start-up. After a test run ( 0000
until 9999 appear on the display) the clock will scan the DCF frequency
signal and the DCF symbol flashes on the display.
• There are three different reception states:
Symbol flashing – reception is active
Symbol solid – signal is found
Symbol solid – reception is very good
• If the clock cannot detect the DCF-signal (e.g. due to interference,
transmitting distance, etc.), the time can be set manually. The DCF
reception symbol disappears and the clock will then work as a normal
quartz clock (see: Manual settings).
Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operat-
ed 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, con-
verts it and always shows the exact time. The adjustment to Daylight Saving
Time (summer/winter time) is automatic. The reception quality depends
mainly on geographic location. Normally there should be no reception pro-
blems within a 1,500 km radius around Frankfurt.
