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
towards the general direction of the Frankfurt/Main transmitter (avoid positioning within close proximity
of metal frames or structures).
Note:
Users may be located in areas where atmospheric disturbances are the direct cause for not receiving the
DCF-77 frequency signal. During nighttime, atmospheric disturbances are usually less severe and reception
is possible in most cases. With a single daily reception, it is adequate for the alarm clock to keep time
deviation to below 0.5 seconds in a period of 24 hours.
When the clock is trying to receive the DCF signal, the reception icon will flash on the LCD. Once the signal
is "locked", the DCF-77 tower icon will stay fixed on LCD and the received time will automatically correct the
