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.
• Remove the protective film from the base station display.
• Insert the power adapter pin into the device jack and connect the plug to a wall socket. Important! Make sure that your
household voltage is no more than 240V! Otherwise your device may be damaged.
• The device will alert you with a beep and all segments will be displayed for a short moment.
• Open the battery compartment of the outdoor transmitter.
• Insert two new AA 1,5 V batteries, polarity as illustrated.
• Close the battery compartment again.
6.2 Reception of outdoor transmitter
• After inserting the batteries, the transmitter will automatically transmit the temperature. The reception symbol will be flash-
ing on the display of the base station.
• If the reception of outdoor temperature fails, "- -" appears 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 – button on the base station for three seconds.
• "- -" appears on the display and the reception symbol flashes on the display. The base station will scan again the outdoor
temperature.
• Press the TX button in the transmitter's battery compartment.

6.3 Reception of the DCF frequency signal
• Press the – button. The clock will now scan the DCF frequency signal and the DCF symbol flashes.
• When the time code is successfully received after 3-10 minutes, the radio-controlled time and the DCF symbol will be
shown steadily on the display.
• The DCF reception always takes place at 2:00, 3:00, 4:00 and 5:00 o'clock in the morning. If the reception is not success-
fully received at 5:00 o'clock, the next DCF reception attempt will happen at 7:00 o'clock.
• There are three different reception states:
flashing – reception is active
solid – reception is very good
no symbol – no DCF reception
• 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).
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 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, converts it and always shows the exact time. The
adjustment to Daylight Saving Time (summer/winter time) is automatic. In Daylight Saving Time the DST symbol is shown on
the LCD. The reception quality depends mainly on geographic location. Normally there should be no reception problems with-
in a 1,500 km radius around Frankfurt.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like computer screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the received signal is naturally weakened. In extreme
cases, please place the unit close to a window to improve reception.
• During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single
daily reception is adequate to keep the accuracy deviation under 1 second.
6.5 Inserting the batteries in the base station
• The batteries will operate as a backup power source in case of power failure.
• For a permanent backlight and to conserve battery power, use the supplied power adapter.
• Open the battery compartment at the back.
• Insert two new AA 1,5 V batteries into the battery compartment. Make sure the polarity is correct.
• Close the battery compartment again.
