First open the battery compartment cover of the device and insert 2 x 1.5V, AAA LR03 batteries
at the correct polarity into the battery compartment (the correct polarity is shown in the battery
compartment). Close the battery compartment cover of the device.
After inserting the batteries, the display light and all display indicators light up briefly. An
acoustic signal will sound. Shortly after that the display will show the measured indoor room
temperature and then returns to standard value. The clock will automatically search for the radio
signal. After approx. 3-5 minutes this process is completed. The radio clock reception
icon (A3) flashes in the display during that process. The clock automatically sets to the correct
time and date when the device receives the radio clock signal. The radio clock reception icon
(A3) lights up steadily. The clock connects to the radio clock signal once daily.
Press and hold the button (B3) for approx. 2 seconds in order to manually search for a radio
clock signal. The radio clock reception icon (A3) flashes in the display during that process.
Note:
While searching the radio clock reception signal, the radio clock reception icon (A3) flashes, and
only the SNOOZE/LIGHT button (B1) is available. All other buttons are not active at that
moment. Press the button (B3) at any time to cancel the search for the radio clock signal.
The search for the radio clock signal will automatically stop, once an alarm gets activated.
Information on synchronizing the radio clock signal
Time and date are radio-controlled. The current time is synchronized with the radio signal from
Frankfurt, Germany (DCF77). DCF77 is a time signal and is normally emitted at the normal
frequency 77.5kHz as time information in coded form. The transmitting power is approx. 50kW
with a broadcasted power of approx. 30kW and coverage of approx. 1500km in the vicinity of
Frankfurt/Main (Mainflingen).
Daylight saving time
In summer the clock automatically switches to daylight saving time and in winter returns to
standard time. If daylight saving time has been set, the daylight saving time indicator (A5)
appears in the display.
