6. Getting started
• Open the battery compartment and remove the insulation strip.
• A short beep will sound and all LCD segments will light up for about 2 seconds.
• The indoor temperature appears on the display.
• The clock will now scan the DCF frequency signal and the DCF symbol flashes
on the LCD. When the time code is received successfully after 3-5 minutes,
the radio-controlled time is displayed and the DCF symbol is displayed steadily
in the LCD.

• If the clock cannot detect a DCF signal (for example due to interference, trans-
mission distance, etc.), the time can be set manually. The DCF symbol disap-
pears and the clock will then work as a normal quartz clock (see: Manual set-
ting of clock and calendar).
• The manually set time will be overwritten by the DCF time when the signal is
received successfully.
Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by
the Physikalisch Technische Bundesanstalt 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 a DCF-77 (77.5 kHz) frequency signal and has
a transmission range of approximately 1500 km. Your radio-controlled clock
receives this signal and converts it to show the precise time. Changeovers from
summer time or winter time are automatic.
summer time. The quality of the reception depends mainly on the geographic loca-
tion. Normally there should be no reception problems within a 1500 km radius
around Frankfurt.
Please take note of the following:
• The recommended distance to any interference sources like computer monitors
or TV sets is at least 1.5 - 2 metres.
• Inside ferro-concrete rooms (basements, superstructures), the received signal
is naturally weakened. In extreme cases, please place the unit close to a win-
dow and/or turn it until the signal improves.
• During nighttime, atmospheric interference is usually less severe and reception
is possible in most cases. A single daily reception is adequate to keep the accu-
racy deviation below 1 second.
