• 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 single daily reception is adequate to keep the accuracy deviation below 1 second.

6. Getting started
6.1 Insert batteries
• Place both instruments on a desk with a distance of approximately 1.5 meter. Check that no other elec-
tronic devices are close.
• Remove the holder of the transmitter and slide down the battery door. Remove the insulation strip.
Place the battery cover on the housing and slide it upwards
• Pull off the protection foil on the display of the station. Open the battery compartment by pushing the
battery cover downwards with your thumbs. Insert the attached batteries (2 x CR2032), polarity as illus-
trated (+pole upwards). Place the battery cover on the housing and slide it upwards.
6.2 Reception of outdoor temperature
• The display unit automatically starts scanning the signals to register the outdoor transmitter after
batteries are inserted. The unit will scan (for 2 min.) the outdoor values.
• If the reception of outdoor values fails, “- -” appears on the display. Check the batteries and try it
again. Check if there is any source of interference.
• Manual initialization can be helpful. Press and hold
▼
button for 3 seconds. The station will only
search for an outdoor transmitter on the actual selected channel.
6.3 Radio controlled time reception
• The clock will scan the DCF frequency signal and the DCF symbol flashes on the LCD. When the signal
is received successfully after 3-8 minutes, the radio controlled time and the DCF symbol appear per-
manently. During the DCF time reception period (maximum 10 minutes), no weather data will be
transmitted.
• There are 4 different reception icons:
- reception is active
- reception is very good
- no reception/time is set manual
No icon
- reception is deactivated (press and hold
▲
button for 2 sec.)
• Press and hold
▲
button again for 2 sec. to activate the reception manually.
• 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: 7.1.1 Manual setting of clock and calendar)
• The radio controlled clock receives the signals at 0:00, 3:00, 6:00 and 12.00 o'clock in the morning.
Note for radio controlled time DCF:
The time base for the radio controlled time is a Caesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt 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 1500 km. Your radio-controlled clock
receives this signal and converts it to show the precise time in summer or wintertime. The quality of
the reception depends greatly on the geographic location. In normal cases, there should be no recep-
tion 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.
