CK 1927 | CK 2309 XL radio-controlled wall clock
English
The transmitter is located in Mainflingen near Frankfurt am Main and, with its range of
up to 2000 km, supplies the majority of radio-controlled clocks in western Europe with
the necessary radio signals.
As soon as the radio-controlled clock is supplied with power, it switches to receiving
mode and searches for the signal from the transmitter DCF77. If the time signal is
received in sufficient strength, the display shows the date, time and day of the week.
The radio-controlled clock switches on several times a day and synchronises the time
with the radio signal from the transmitter DCF77. In the event the signal is not received,
e.g. during a strong storm, the device continues to run precisely and then switches to
receiving mode again at the next scheduled time.
Alarm
The device offers the possibility of setting two alarm times independently of each
other. For each alarm time you can specify the days on which it should be active:
 Monday to Friday (“M-F” display) or
 Saturday to Sunday (“S-S” display) or
 Monday to Sunday (“M-S” display).
Setting the alarm time

button, the setting process automatically ends and you will have to
