ADE CK 1713 Bedienungsanleitung Seite 40

From now on the radio-controlled alarm clock
automatically switches to receiving mode
several times a day and compares its own time
with that received by the time signal transmitter.
If there is a difference, the time displayed on the
alarm clock will be automatically corrected.
If no sufficiently strong signal has been received,
the radio-controlled alarm clock will cancel the
reception process. In this case:
‚ Check whether the location of the radio-
controlled alarm clock is suitable; see "Tips
for good reception".
‚ To restart the reception process, remove the
battery and reinsert it.
‚ Set the time manually, if necessary; see "Set
the time manually".
