5. Getting started
5.1 Insert the batteries
• Place the instruments on a table at a distance of about
1.5 meters from each other. Avoid being close to pos-
sible sources of interference such as electronic
devices and radio equipment.
• Open the battery compartment of the transmitter and
insert two new AA 1.5 V batteries, polarity as illustrat-
ed. All LCD segments will be displayed for a short
moment. The display shows the temperature. The
switch is set to channel 1.
• Close the battery compartment.
• Remove the protective film from the base station dis-
play.
• Open the battery compartment of the base station.
• Insert two new AA 1.5 V batteries, polarity as illustrat-
ed. All LCD segments will be displayed for a short
moment. The indoor temperature appears on the dis-
play.
• Close the battery compartment.
5.2 Reception of outdoor transmitter
• The base station will scan the outdoor temperature
and the reception symbol flashes.
• If the reception is successful, the outdoor temperature
and the reception symbol appear steadily on the base
station display.

• If the reception of the outdoor temperature fails, “- -,-”
remains on the display. Check the batteries and try it
again.
• You can also activate the reception manually. Press
and hold the
+/CHANNEL
button on the base station
for three seconds. The reception symbol for the out-
door transmitter will be flashing.
• Press the
TX
button in the transmitter's battery com-
partment. The transmission of the outdoor data takes
place immediately and if the reception is successful,
the outdoor temperature appears on the base station
display.
5.3 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.
• The DCF reception always takes place at 1:00, 2:00
and 3:00 o'clock in the morning. If the signal is not
successfully received, further attempts will be taken at
4:00 and 5:00 o'clock.
• If the clock cannot detect the DCF-signal (e.g. due to
interference, transmitting distance, etc.), the time can
be set manually.
• The clock will then work as a normal quartz clock
(see: “Manual settings”).
Note on radio-controlled time
• The time is transmitted from an atomic clock near
Frankfurt am Main by a DCF-77 (77.5 kHz) frequency
signal with a range of about 1,500 km. Your radio-con-
trolled clock receives the signal, converts it and always
shows the exact time. The adjustment of Daylight Sav-
ing Time and Standard Time is also automatic.
• During night-time, the atmospheric interference is usu-
ally less severe. A single daily reception is adequate to
keep the accuracy deviation under 1 second. In extreme
cases, please place the unit close to a window to
improve reception.
