INSTALLATION
Outdoor sensor:
Slide down the battery cover to open it. Use
the slider to set the outdoor sensor to the
desired channel (CH 1-2-3-4-5-6-7-8). Insert
2 alkaline batteries type 2 x 1.5V AA, LR6 into
the battery compartment of the outdoor sensor
in the correct way . Y ou may now replace the
battery cover .
After installing the batteries, you can no longer
adjust the channel. This can only be done by
changing the channel setup using the slider
and then restarting the outdoor sensor by
brieyremovingthebatteriesandreplacing
them or by pressing the reset button.
Every time the outdoor sensor is switched on
(for example after replacing the batteries) or
after pressing the reset button, the outdoor
sensor must be reconnected to the clock.

outdoor sensor . Press the “SENSOR ” button
to start reception. Select the same channel
on the outdoor sensor , it is now automatically
registered or press the “RCC ” key in the

a 230V wall socket. After this connection the
clock will start-up .
Press the reset button to synchronize the clock
with the outdoor sensor and the DCF time
signal. The outdoor sensor icon “ ”
nowstartsashingwhiletheclockis
automatically searching for the outdoor sensor .
As soon as the outdoor sensor has been found,
the “ ” icon appears in the display . The
outdoor sensor will now start receiving the
DCF time signal. When the outdoor sensor has
found this signal, the time is transmitted to the
clock and the “ ” icon and DCF-77 time will
appear in the display .
The DCF-77 reception icon indicates whether
the DCF-77 signal is synchronised.
-5-
Each day the clock automatically searches for
the DCF-77 signal to attempt to synchronize
the clock. This occurs at 2am, 8am, 2pm and
8pm. The reception is strongest at night at
2am. Don’t place the outdoor sensor near a TV ,
computer , etc.
Notes:
DCF stands for the reception from Frankfurt
(DCF-77)
DST stands for “Daylight Saving Time” or
summertime
DST is indicated together with the DCF-77-
time.
Remark:
The clock may also be used without the
outdoor sensor . In this case the display shows
the value “--” .
The measurement cycle of the outdoor sensor
is 60-64 seconds.
DISPLAYS
General:
The actual time, date and day , temperature
and humidity are displayed correctly after both
the clock and the outdoor sensor have been
switched on for sever al hours and have not
been moved.
CLOCK SETUP AND OPERATION
Time and date:
The outdoor sensor contains a built-in DCF-
77 receiver . This receiver is used for receiving
the DCF time signal from Frankfurt. This
signal ensures that the clock displays a
very accur ate time, provided that the signal
reception is successful. The DCF 77 receiver
is located inside the outdoor sensor . It may
take sever al hours before the time signal is
shown in the display of the clock. In case of
a poor reception, you may mo ve the outdoor
sensor to improve the reception of the DCF-
77 signal. Press the “RCC” button in the
battery compartment of the outdoor sensor to
manually start the reception.
