TWIST
– Radio-controlled alarm clock
5.3 Note on radio-controlled time
• The time is transmitted from an atomic clock near Frankfurt am Main by a DCF-77 (77.5 kHz)
frequency signal with a range of about 1,500 km. Your radio-controlled clock receives the sig-
nal, converts it and always shows the exact time. The adjustment of Daylight Saving Time and
Standard Time is also automatic.
• Make sure to avoid the vicinity of any source of interference such as computer screens, TV sets
or solid metal objects. Within concrete walls (reinforced with steel) such as basements, the
received signal is naturally weakened. In extreme cases, please place the unit close to a window
to improve reception.
• During night-time, the atmospheric interference is usually less severe. A single daily reception
is adequate to keep the accuracy deviation under 1 second.
