Check the polarity on your battery to make sure it is installed according to the diagram in the battery compartment. Also 
make sure that you are using a quality alkaline battery. We advise against reloading batteries. 

This alarm clock receives a signal from Frankfurt (DCF-77) to set the clock and the calendar to atomic time. Sometimes, 
due to adverse weather or atmospheric conditions you will not be able to receive a signal immediately. The best way to get 
a signal is to put your alarm clock in a window facing Frankfurt until you see the tower icon appear. If definitely you are 
not receiving the signal, wait one night : during the night time there are less atmospheric disturbances.

 

 

In case the clock do not receive the DCF-77 signal, it is possible to manually set time. Proceed as follows :  

1.  Press the MODE key until time will start flashing. Then use the ALM1/HOUR key to set time, and the ALM2/MIN 

key to set the minutes.  

Once time is set, exit the manual setting mode by pressing the SNOOZE key.  

Once the DCF-77 time signal is received or the time has been manually set, proceed as follows to set the alarm :  

1.  Press and hold the ALM1/HOUR key until the alarm time will start flashing (right of the screen).  
2.  Set the hours and minutes of the desired alarm time by using the ALM1/HOUR (hours) or the ALM2/MIN 

(minutes) keys respectively.  

3.  Once the alarm time is set, press the SNOOZE key to confirm and exit . 

The same procedure must be follow to set the second alarm time (use the ALM2/MIN key).
