1.1 Usable time signal transmitters

Your Junghans multi-frequency radio-controlled watch is capable of fully
automatic 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 coun-
try) 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 applian-
ces or dimmer switches), the Junghans multi-frequency radio-controlled
watch will launch renewed attempts to pick up the signal fully automatical-
ly the following night.
It is also possible to use a 'transmitter call' to synchronise the time manual-
ly, for example at a location where reception conditions are better.
The latest time information received is stored in a time memory. This origi-
nal time continues to be kept using a high-precision 32 kHz quartz move-
ment until the time is synchronised again. The radio-controlled time syn-
chronisation 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 automa-
tically (at night).
Please note that this does not apply to the USA's WWVB time signal trans-
mitter (see section 3).
If you travel to a country in a different time zone, the time adjustment facili-
ty on your Junghans multi-frequency radio-controlled watch makes it easy to
switch to the appropriate local time.
