• All segments will be displayed briefly.
• Close the battery compartment again.
6.1.1 Transmitters' reception
• After the batteries are inserted the base station will automatically receive the measured values. The recep-
tion symbol will be flashing on the display.
• If the reception of the measured values fails, "- -" appears on the display. Check the batteries and try it
again. Check if there is any source of interference.
• As soon as the base station receives the radio-controlled time, you can start the transmitters manual ini-
tialization. Choose the respective transmitter by pressing the Channel button. Press and hold the Channel
button for four seconds. The base station tries to receive the measured values.
• For testing, or in case of transmitter signal loss, press the TX button to transmit the measured values man-
ually.
6.2 Radio-controlled time reception
• After the base station has completed searching for the transmitters, the device starts scanning the DCF sig-
nal and the DCF reception symbol will be flashing.
• When the time code is successfully received after 2-10 minutes, the radio-controlled time, the date, the
DST (if applicable) and the DCF symbols will be shown steadily on the display.
• The DCF reception always takes place hourly between 1:00 and 5:00 o'clock in the morning. If the reception
is not successfully received until 5:00 o'clock, the next DCF reception attempt will happen at 1:00 o'clock in
the following morning.
• There are three different reception symbols:
flashing - reception is active
solid - reception is very good
No symbol - no reception / set the clock manually
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can
be set manually. The DCF reception symbol disappears and the clock will then work as a normal quartz
clock (see: Manual settings).
7. Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig. 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. The adjustment to Daylight Saving Time (summer/winter time)
is automatic. In Daylight Saving Time the DST symbol is shown on the display. The reception quality depends
mainly on geographic location. Normally there should be no reception problems within 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.
8. Operation
• Important: a button operation is not possible during the reception of the transmitters signal or of the radio-
controlled time signal.
• Press and hold the MaxMin/+ or RCC/- button in the respective setting mode for fast setting.
• The device will automatically quit the setting mode if no button is pressed for 20 seconds.

8.1 Manual settings

• Press and hold the Set button in normal mode.
• dcF appears on the display and on (default) will be flashing.
• Press the MaxMin/+ or RCC/- button to deactivate (OFF) or activate (on) the DCF time reception.
• Once the DCF time reception is deactivated, the clock must be manually set.
• Press the Set button to do the settings in the following sequence: Time zone (0 - default), the 12 or 24-
hour system (24hr - default), the hours, the minutes, the year, the month, the day and the temperature dis-
play (°C - default), Press the MaxMin/+ or RCC/- button to adjust it.
• Confirm with the Set button.
• Once the DCF time signal is successfully received, the manually set time is overwritten, if the DCF reception
is activated.
8.1.1 Time zone setting
• In the setting mode you can make the time zone correction (-12/+12).
• The time zone correction is needed for countries where the DCF signal can be received but the time zone is
different from the DCF time (e.g. +1=one hour plus).
8.1.2 12/24-hour display setting
• Press the MaxMin/+ or RCC/- button in the setting mode to choose between the 12 or 24-hour system.
• In the 12-hour system AM or PM (after 12 o'clock) appears on the display as well as the American date for-
mat (month first, then the day).
8.1.3 Temperature display setting
• Press the MaxMin/+ or RCC/- button in the setting mode to select the temperature display in °C (Celsius)
or °F (Fahrenheit) as temperature unit.
8.2 Trend arrows
• The trend arrows indicate whether the temperature and humidity values are currently increasing or
decreasing. If the arrows are steady, there is no change.
8.3 Maximum/Minimum function
• Press the MaxMin/+ button in normal mode.
• appears on the display.
• The maximum values measured since the last reset appear on the display.
• Press the MaxMin/+ button again.
• appears on the display.
• The minimum values measured since the last reset appear on the display.
