If the clock cannot detect the DCF-signal (for example due to
disturbances, transmitting distance, etc.), the time can be set
manually. The clock will then work as a normal quartz clock.

Radio-controlled time reception
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 Main-
flingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and
has a transmitting range of approximately 1,500 km. Changeover
from summer time or winter time is automatic. In Daylight Saving
Time is shown on the LCD. The quality 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.
