You can start the initialization manually. Press the SENSOR button on
the basic station.
4.1. Radio-controlled time reception
•
After approximately 5 minutes after the installation of the batteries,
the clock will scan the DCF frequency signal and the DCF symbol will be
flashing. When the time code is received successfully after 6-16 minutes,
the radio-controlled time and the DCF symbol are displayed steadily in
the LCD.
•
You can also start the initialization manually.
•
Press the RCC button.
•
The DCF symbol will be flashing.
•
Interrupt the reception by pressing the RCC button again for three
seconds. The DCF symbol disappears.
•
The DCF reception always take place at 2:00 am, 8:00 am, 14.00 pm and
20.00 pm o'clock. If the reception is not successfully received at 2:00
clock, it shall be held further attempts at 3.00 am and 4.00 am.
•
If the clock cannot detect the DCF-signal (for example due to distur-
bances, transmitting distance, etc.), the time can be set manually. The
DCF symbol disappears and the clock will then work as a normal quartz
clock. (see: Manual setting of the clock).
4.1.1 Note for radio-controlled time DCF
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 frequency
signal DCF-77 (77.5 kHz) and has a transmitting range of approximately
1,500 km. Your radio-controlled clock receives this signal and converts it to
show the precise time. Changeover from summer time or winter time is
automatic. In Daylight Saving Time “DST” is shown on the LCD. The quali-
ty of the reception depends mainly on the geographic location. Normally
there should be no reception problems within a 1,500 km radius around
Frankfurt.
Please take note of the following:
•
The recommended distance to any interfering sources like computer
monitors or TV sets is at least 1.5 - 2 meters.

4. Getting started
•
Place the basic station and the outdoor transmitter on a desk with a dis-
tance of approximately 1.5 meter. Avoid getting close to possible inter-
ference sources (Electronic devices and radio installations).
•
Remove the protective foil from the display of the basic station.
•
Open the battery compartment of the basic station and insert two new
batteries 1.5 V AA, polarity as illustrated. Close the battery compart-
ment again.
•
Open the battery compartment of the outdoor transmitter.
•
For the first outdoor transmitter set the CH 1/2/3 switch to number one.
•
Insert two new batteries 1,5 V AA, polarity as illustrated. On the display
appear the outdoor temperature and humidity in sequence and the
channel number 1. The signal lamp will be flashing.
•
Press at first the RESET button on the basic station by using a pointed
object and press than the RESET button in the battery compartment of
the outdoor transmitter. Close the battery compartment of the outdoor
transmitter again.
•
The indoor temperature and humidity will be displayed on the basic
station and the basic station will now scan the outdoor temperature
and humidity. The reception symbol will be flashing. If the reception is
successful on the display appear the outdoor values and the set canal
number.
•
If the reception of outdoor temperature and humidity fails, “- -”
appears on the display. Check the batteries and try it again. Check if
there is any source of interference.
