6. Getting started

6.1 Inserting the batteries

• The batteries will operate as a backup power source in case of power failure.
• For a permanent projection, to use the charging function and to conserve bat-

tery power, use the supplied power adapter.

• Open the battery compartment and insert two new batteries 1,5 V AA, polarity

as illustrated.

• Close the battery compartment again.
• Insert the adapter into the jack at the device and connect the power adapter to

a wall socket.

•

Important!

Make sure that your household voltage is not more than 240V!

Otherwise your device may be damaged.

• The device is ready for use. All LCD segments will light up for about 2 se-

conds.

• The clock will scan the DCF frequency signal and the DCF symbol flashes on

the LCD. When the signal is received successfully after 3-5 minutes, the radio
controlled time and the DCF symbol appears permanently.

• In Daylight Saving Time “S” is shown on the LCD.
• If the reception fails, activate the reception manually by holding

°C / °F /

WAVE

button for 2 seconds.

• In case the clock cannot detect the DCF-signal (for example due to distur-

bances, transmitting distance, etc.), the time can be set manually. The clock
will then work as a normal quartz clock. (see Manual setting of clock and cal-
endar).

Note for radio-controlled time DCF

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

Radio-controlled projection alarm clock with thermometer

of less than one second in one million years. The time is coded and transmitted
from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has
a transmitting range of approximately 1,500 km. Your radio-controlled clock
receives this signal and converts it to show the precise time. Changeover from
summer time or winter time is automatic. The quality of the reception depends
mainly on the geographic location. 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.

• Inside ferro-concrete rooms (basements, superstructures), the received signal

is naturally weakened. In extreme cases, please place the unit close to a window
to improve the reception.

• During night-time, the atmospheric interference is usually less severe and

reception is possible in most cases. A single daily reception is adequate to keep
the accuracy deviation under 1 second.

7. Operation

7.1 Manual setting of clock and calendar

• Hold the

MODE

button for 2 seconds in normal mode. The year is flashing.
