5. Operation
5.1 Battery
Do not puncture batteries or throw them in fire as they may explode. Do not attempt to
recharge non-rechargeable batteries (alkaline). Dispose of batteries in accordance with
local regulations. Keep batteries away from children.
Insert the battery observing the correct polarity. Close the battery compartment before
use.
5.2 Working Principle
The clock contains a receiver, which receives a radio-signal from a radio station located
near Frankfurt, Germany. This long-wave radio-signal (DCF77) is based on atomic
clocks and contains time and date information. The clock automatically synchronizes
with this master clock radio-signal and when necessary adjusts the positions of second,
minute or hour hands of the clock.
Due to its nature, the radio-signal can be received indoors. However, it should be noted
that the signal is weakened by the presence of concrete and metal. Therefore, the clock
must not be installed in concrete basements or inside metal cages. In large concrete
office buildings or apartments, the clock should be located near a window for better
reception.
Also, avoid installing the clock near strong magnetic fields or other devices that
generate a lot of electrical noise (e.g. engines).
5.3 Operation
Remove the protection pin before first use! Dispose of it in a safe way.
Do not attempt to reinsert the pin afterwards as this will surely damage the clock.
1. Insert a battery in the battery compartment. All hands will move forward towards
12:00. Note: when the original position of the second hand is between 11:55 and
12:00, the second hand will make a full turn before stopping at 12:00. The same
happens with the minute hand when the original position is between 11:52 and
12:00.
2. Choose a location for the clock (see Working principle).
3. Wait until the clock receives the synchronization signal from the master clock. This
might take up to 15 minutes. Note that the received signal is usually stronger at
night.
4. Once synchronized, the hands will start moving towards the correct time.
5. When the clock does not receive the radio-signal, it will start running showing the
wrong time. However, it will keep attempting to synchronize.
