SOLAR - Radio-controlled alarm clock
Important information on product safety!
• Make sure that no objects cover the solar panel.
• Attention: The solar panel is very damageable. Do not drop
the instrument and avoid collisions, vibration or extreme
temperatures.
• Protect the instrument from moisture.

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.

SOLAR - Radio-controlled alarm clock
• After start-up the clock will scan the DCF time signal (
es on the LCD). The signal appears permanently when it is
received successfully. Important: Buttons will not function
while scanning for DCF.
• The clock automatically scans the time signal at 3.00 a.m.
everyday to maintain accurate timing. For failed reception,
scanning 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 "▼( )"
button for 3 seconds
• Press "▼ ( )" button to stop scanning.
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
Mainflingen 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 recep-
tion 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.
• During nighttime, 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.
