6. Getting started
6.1 Insert the batteries
• Place the instruments on a table at a distance of about 1.5
meters from each other. Avoid being close to possible sources
of interference such as electronic devices and radio equipment.
• Open the battery compartment of the outdoor transmitter.
• Insert two new AA 1.5 V batteries, polarity as illustrated.
• The LED signal lamp flashes.
• Close the battery compartment.
• Open the battery compartment at the back of the base station.
• Insert two new AA 1,5 V batteries into the battery compartment.
Make sure the polarities are correct.
• The device will alert you with a beep and all segments will be
displayed for a short moment.
• Close the battery compartment.
6.2 Reception of outdoor transmitter
• After inserting the batteries, the transmitter will automatically
transmit the temperature. The reception symbol will be flashing
on the display.
• If the reception of the outdoor temperature fails, “- -” remains
on the display. Check the batteries and try it again. Check if
there is any source of interference.
• You can also start the initialization manually. Hold the MAX/MIN
button on the base station for three seconds.
• “- -” appears on the outdoor temperature display and the recep-
tion symbol flashes. The base station will scan the outdoor tem-
perature.
• Press the TX button in the transmitter's battery compartment.
The transmission of the outdoor data takes place immediately
and a successful reception will be confirmed by a beep tone.

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, the date and the DCF symbol will be
shown steadily on the display.
• If reception fails, the clock will then try to receive the signal
every 2 hours again.
• After successful reception, DCF radio reception takes place daily
at 1:00, 2:00, 3:00, 4:00 and 5:00 in the morning.
• You can also activate the DCF reception manually. Press the SET
button. The clock will now scan the DCF frequency signal and
the DCF symbol flashes.
• If the clock cannot detect the DCF-signal (e.g. due to interfer-
ence, 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 devia-
tion of less than one second in one million years. The time is
coded and transmitted from Mainflingen near Frankfurt via the fre-
quency 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 Day-
light Saving Time (summer/winter time) is automatic. The recep-
tion quality depends mainly on geographic location. Normally there
should be no reception problems within a 1,500 km radius around
Frankfurt.
