• The batteries (see "Specifications") cannot and must not be
replaced or removed by you. There is a risk of explosion if the
batteries are replaced incorrectly. If necessary, a qualified per-
son can obtain instructions on how to dismantle the permanent-
ly installed batteries from info@tfa-dostmann.de , should this be
necessary for the purpose of repairing or recycling the product.
• Keep this device out of reach of children.
• Small parts can be swallowed by children (under three years
old).
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, vibrations or extreme tempera-
tures.
• Protect the instrument from moisture.

SOLAR - Radio-controlled alarm clock
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. The
built-in battery (CR2477) will operate as a backup power source
in case the solar panel has not received adequate light. 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 (
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 "▼
( )" 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 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.
