7. Operation
Important:

Remove the protection pin [E] 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 (see below). 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 6. 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 time.
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.
Manual setting

It is possible to set the time manually, e.g. for use in places where no radio-signal is received.

Press and hold the manual set button [C]. After ± 3 seconds the minutes and hour hands start
moving. Hold down the manual set button [C] and release a couple of minutes before desired time
setting. Press the manual set button [C] repeatedly until the desired time indication is reached.
When no press is detected within 7 seconds, the clock starts running.
Forced receiving

To force the clock to synchronize, press and hold the forced receiving button [B] for ± 3 seconds.
The current time is stored in memory and all hands will start moving towards 12:00. The clock
attempts to synchronize with the master clock.

When synchronization is successful, the hands will move towards the correct time. If it fails however,
the hands will move towards the time that was memorized.
Reset

To reset the time and memory, use a piece of metal (e.g. a blank paperclip) to short circuit the two
metal reset pins [A].

All hands will move to the 12:00 position and the memory is cleared. The clock will attempt to
synchronize to the master clock.
8. Cleaning and maintenance

Wipe the device regularly with a moist, lint-free cloth.

Do not use alcohol or solvents.
9. Battery

Insert a new 1.5 V AA battery in the battery compartment [D] in accordance with the polarity
markings inside the battery compartment.
