Note:
The projector will only project the current time. It will not project the seconds, date or temperature
information.
RADIO CONTROLLED TIME:
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 every 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. The Projection clock receives this signal and
converts it to show the precise time and so when within this range the received time is completely accurate.
CHECKING FOR DCF-77 RECEPTION:
The Projection clock will automatically start scanning for the DCF-77 frequency signal after the battery is
inserted. In normal surroundings (for example away from interfering sources such as TV sets), it takes
between 3-5 minutes to receive the signal. If after 10 minutes after having inserted the batteries into the
alarm clock and the DCF-77 signal is not received, then check the following list before manually setting the
time (see Manual time setting):
1.
The distance of the Projection clock should be at least 1.5-2.0 meters away from interfering sources
such as computer monitors or TV sets.
2.
Avoid placing the alarm clock onto or in the immediate proximity of metal, doors, windows frames or
structures.
3.
Within thick concrete rooms such as basements and tower blocks, the DCF-77 signal is naturally
weaker. In extreme cases, place the alarm clock closer to a window and/or point its front or rear
