The Moon Phase Clock's LCD is divided into 2 sections and once the batteries are
inserted, all the segments will light up briefly before displaying:
DCF time
Alarm icon
LCD1- DCF RADIO CONTROLLED TIME, ALARM AND SNOOZE
Once the batteries are inserted into the battery compartment, the Moon Phase Clock will
receive the DCF time within 3-5 minutes. Once received, all segments of the clock will
display the informations accordingly, then no further reception will take place for the DCF
signal that day.
The DCF reception takes places at 2:00 and 3:00 am each day. If the clock is unable to
receive the reception, it will attempt to receive the DCF time at the next full hour or as long
as it receives the DCF time successfully.
The time base for the radio controlled time is a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation 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 Moon Phase Clock receives this signal and
converts it to show the precise time in summer or wintertime. The quality of the reception
depends greatly on the geographic location. In normal cases, there should be no reception
problems within a 1500km radius of Frankfurt.
When the time code is received, the DCF tower becomes permanently lit and the time will
be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all,
then please take note of the following:
Recommended distance to any interfering sources like computer monitors or TV sets
is a minimum of 1.5 - 2 meters.
Within ferro-concrete rooms (basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window and/
or point its front or back towards the Frankfurt transmitter.
During nighttime, the atmospheric disturbances are usually less severe and
reception is possible in most cases. A single daily reception is adequate to keep the
accuracy deviation below 1 second.
