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 dis-
play. 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 reception sym-
bol flashes. The base station will scan the outdoor temperature.
• Press the TX button in the transmitter's battery compartment. The trans-
mission 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 interference, trans-
mitting 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 opera-
ted 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.
