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.
1. 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.
2. Insert a new battery in the battery compartment in accordance with the polarity
markings inside the battery compartment.
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
Starting the Movement
Make sure the batteries have been inserted correctly.
Zero Position
Once the batteries are installed, the clock hands will automatically run and stop at
12:00. Press reset if the hands are not on the 12:00 position.
Reception Mode
Movement will start receiving the signal after 3 to 15 minutes. The reception time
depends on the frequency quality at your location.
Automatic Time Setting
The clock hands will move to the correct time after the reception is completed.
Manual Time Setting
Press and hold the setting button to set the time manually. The hands will stop moving
once you release the setting button.
