[. . . ] First, slide to open the battery cover at the back of the alarm clock as indicated above. Checking the correct polarization, insert 1 x AA, IEC LR6, 1. 5V battery into the battery compartment and replace the cover. When the battery is inserted, all the segments of the LCD will light up briefly and a "beep" sound will be heard before entering the radio controlled time reception mode. Within 30 seconds, the `DCF-77 Tower' icon will appear and start flashing. [. . . ] Within thick concrete rooms such as basements and tower blocks, the DCF-77 signal is naturally weaker. In extreme cases, place the alarm clock closer to a window and/or point its front or rear towards the general direction of the Frankfurt transmitter (avoid placing near metal frames and structures). Note: Users may be located in areas where atmospheric disturbances are the direct cause for not receiving the DCF-77 frequency signal. During nighttime, atmospheric disturbances are usually less severe and reception is possible in most cases. With a single daily reception, it is adequate for the alarm clock to keep time deviation to below 1 second in a period of 24 hours. When scanning for time signal, the `DCF-77 Tower' icon will start flashing on the LCD as a sign that the signal has been found and reception is being attempted. Once the signal is "locked", the `DCF-77 Tower' icon will stay fixed on the LCD and the received time will automatically correct the manually set time. As well as the time, the date will also be received by the alarm clock which is displayed accordingly in the calendar section of the LCD. 1.

Once the time is set, either press the SNOOZE key or wait for automatic timeout to exit the manual time setting mode. Note: The calendar will not be displayed when time has been manually set. It only will be displayed when DCF reception is successful. ALARM 1 AND ALARM 2 SETTINGS Alarm 2 Icon Alarm Time Display 1.
