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)

Operation

Important:



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.

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.

Choose a location for the clock (see section Working principle).

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.

Once synchronized, the hands will start moving towards the correct time.

When the clock doesn't 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
