Note: Please do not move the alarm clock during the reception process.
The alarm clock synchronizes the internal clock every day from 01:00 to 04:00 on each
full hour. If reception is unsuccessful, the clock will reattempt reception at 05:00 and
06:00. Please set the time manually, if reception fails (see "Basic settings").
If reception is successful, the
radio tower indicator
5
appears permanently on the
display and the time, date and day of the week are set automatically. During daylight
saving time, DST appears on the display next to the radio tower indicator.
Time zone adjustment
If you are in a country in which the current time is incorrect even though the DCF77
signal was received, please use the time zone adjustment to adjust the time zone to a
different setting than the standard setting (UTC+1 = Central European Time). Set the
difference in hours (for example -01) to the required time zone.
Press and hold
SET / °C / °F 14
for 3 seconds in normal time display mode. The
language of the day of the week will blink. Press
SET / °C / °F 14
8x. Now the
time
zone will blink (00) and can be set using
/ ALARM ON / OFF 17
or
/ RCC OFF 18.
Confirm your setting by pressing
SET / °C / °F 14
.
Now perform a restart. The clock will continue to receive the DCF-77 radio control signal
but will show the changed time (for example, 1 hour less).
Restart
Radio reception can be manually restarted by pressing
RCC / RESET 16
on the backside
of the clock for 4 seconds. The
radio tower

Reception problems
The DCF77 radio signal is transmitted from a location near Frankfurt am Main and can
be received within a radius of approximately 1500 km around Frankfurt am Main.
However, there are some obstacles and sources of interference, which may substantially
hinder reception. If your alarm clock does not correctly receive the DCF77 radio signal,
please hang or place the alarm clock a different location at your site. Please note that
devices such as computers, telephones, radios and televisions may cause
electromagnetic radiation which can interfere with the DCF77 signal reception. Other
possible detriments to reception are: strong building insulation (metal building materials),
nearby mountains or atmospheric interference. It may also be necessary to replace the
batteries.
Light
Press
SNOOZE / LIGHT 2
on the top of the clock to briefly activate the light.
