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 a. M.) for Europe
– WWVB in Fort Collins, Colorado (USA) for North America
– JJY40
on Mount Othakadoya (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), South Korea and parts of Taiwan.

With good reception, the Junghans Worldtimer Chronoscope will thus
always show the absolutely correct time within any of these four transmis-
sion areas. The Junghans Worldtimer Chronoscope automatically synchroni-
ses itself overnight with the DCF77, WWVB, JJY40 and JJY60 time signal trans-
mitters.
If reception fails due to interference (e. g. thunderstorms, electrical applian-
ces), the Junghans Worldtimer Chronoscope will automatically retry signal
reception in 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 most recent time information received is stored internally in a time
memory. This original time continues to be kept using a high-precision 32kHz
quartz movement until the time is synchronised again. The radio-controlled
time synchronisation of your Junghans Worldtimer Chronoscope not only
ensures an always precise display of the time. Given good reception, it also
takes care of switching from winter to summer time, and vice versa, automa-
tically (at night).
Please note, that this does not apply to the time signal transmitter WWVB
(USA). (see chapter 2)
If you travel to a country with a different time zone, the time zone adjust-
ment facility on your Junghans Worldtimer Chronoscope makes it easy to
switch to local time.
