6. Getting started
• Remove the protective foil from the solar panel.
• Push the “POWER ON/OFF” slide to “ON” to switch on the unit.
• The SOLAR radio-controlled alarm clock is solar-powered and
needs no further power source like batteries or power adapter.
Please consider when choosing a location that the solar panel
needs at least 4 hours of light per day to guarantee a long-term
sufficient power supply.

• After start-up the clock will scan the DCF time signal (
flashes
on the LCD). The signal appears permanently when it is received
successfully.
Important:
Buttons will not function while scan-
ning for DCF.
• The clock automatically scans the time signal at 3.00 a.m.
everyday to maintain accurate timing. For failed reception, scan-
ning stops (
disappears from the LCD) and repeats again at
4.00 a.m. 5.00 a.m. and 6.00 a.m.
• The clock manually scans the DCF time signal by holding “

disappears from the
LCD.
• In case the clock cannot detect the DCF-signal (for example due
to disturbances, transmitting distance, etc.), the time can be set
manually. The clock will then work as a normal quartz clock.
(see “Manual setting of the clock and calendar”).
Radio-controlled time reception
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 of less than one second in
one million years. The time is coded and transmitted from Main-
flingen near Frankfurt via a DCF-77 (77.5 kHz) frequency signal
and has a transmission range of approximately 1500 km. Your
radio-controlled clock receives this signal and converts it to show
the precise time. Changeovers from summer time or winter time
are automatic. In Daylight Saving Time “DST” is shown on the LCD.
The quality of the reception depends mainly on the geographic
location. Normally there should be no reception problems within a
1500 km radius around Frankfurt.
Please take note of the following:
• The recommended distance to any interference sources like
computer monitors or TV sets is at least 1.5 - 2 metres.
• Inside ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please
place the unit close to a window and/or turn it until the signal
improves.
