Radio-controlled alarm clock with thermometer
C: Housing:
C 1: Light sensor
C 2: Battery compartment
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 sym-
bol flashes on the LCD. When the time code is received success-
fully 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 interfe-
rence, transmission distance, etc.), the time can be set manually.
The DCF symbol disappears and the clock will then work as a nor-
mal quartz clock (see: Manual setting 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.
play during summer time. The quality of the reception depends main-
ly on the geographic location. Normally there should be no reception
problems within a 1500 km radius around Frankfurt.
Please take note of the following:
• 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 recei-
ved signal is naturally weakened. In extreme cases, please place the
unit close to a window 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 accuracy deviation below 1 second.
7. Operation
• The instrument will automatically quit the setting mode if no but-
ton is pressed within 30 seconds.
• Press and hold the "+" or "-" button in the setting mode for fast
running.
7.1 Manual setting of clock and calendar
• Press and hold the MODE button in normal mode for three
seconds. The hour digit flashes. Press the "+" or "-" button to
adjust hours.
