Please observe a minimal distance of 2.5m to sources of interference such as
televisions or computer screens.

The radio signal reception is weaker in rooms with concrete walls, e.g. in the
basement and in office buildings. For extreme cases, please put the clock near a
window.

There are less atmospheric disturbances at night. A radio time signal reception is
usually possible at that time. One synchronisation per day is sufficient to keep the time
display accuracy at 1 second.
