1.1 Usable time signal transmitters
Your Junghans multi-frequency radio-controlled watch is capable of fully auto-
matic reception of time signals from the following transmitters:
– DCF77
in Mainflingen (Frankfurt am Main) for
Europe
– WWVB in Fort Collins, Colorado (USA) for
North America
– JJY40 on Mount Otakadoya (near Tokyo in the North East of the country)
for
Japan
– JJY60 on Mount Hagane (in south western Japan) for
Japan
, the
east
coast of China
(Shanghai), für
South Korea
and parts of
Taiwan
.
With good reception, the Junghans multi-frequency radio-controlled watch
thus always shows the perfectly correct time within any of these four trans-
mission areas. The watch automatically synchronises itself overnight with the
DCF77, WWVB, JJY40 and JJY60 time signal transmitters.
If reception fails due to interference (e. g. stormy weather, electrical appliances
or dimmer switches), the Junghans multi-frequency radio-controlled watch
will launch renewed attempts to pick up the signal fully automatically the fol-
lowing night.
It is also possible to use a ‘transmitter call’ to synchronise the time manually,
for example at a location where reception conditions are better.
The latest time information received is stored in a time memory. This original
time continues to be kept using a high-precision 32 kHz quartz movement
until the time is synchronised again. The radio-controlled time synchronisation
of your Junghans multi-frequency watch not only ensures an always precise
display of the time, but – given good reception – also takes care of switching
from winter to summer time, and vice versa, fully automatically (at night).
Please note that this does not apply to the USA’s WWVB time signal transmit-
ter (see section 3).
If you travel to a country in a different time zone, the time adjustment facility
on your Junghans multi-frequency radio-controlled watch makes it easy to
switch to the appropriate local time.
