Your Junghans Mega Futura radio-controlled watch is able to automa-
tically receive the radio signals of the following time signal transmitter
stations:
– DCF77
in Mainflingen (24km south-east of Frankfurt am Main) for
Europe
,
– JJY40
on Mount Ohtakadoya (near Tokyo in north-east Japan) for
Japan
– JJY60
on Mount Hagane (in south-west Japan) for
Japan
,
the
East coast of China
(Shanghai),
for
South Korea
and parts of
Taiwan
– WWVB in Fort Collins, Colorado (USA) for
North America
This means that within range of one of these 4 transmitter stations
your Junghans Mega Futura will display the exact time when reception
conditions are adequate. Junghans radio-controlled wristwatches
automatically synchronise themselves every day with the DCF77, JJY40,
JJY60 and WWVB time signal transmitters. If your Junghans Mega
Futura radio- controlled watch is unable to receive a signal due to inter-
ference (e.g. thunder storms, electronic devices, lighting dimmer swit-
ches) it will automatically attempt to receive a signal the following day
at the same time. The time can also be synchronised manually by cal-
ling a transmitter e.g. from a place with better reception. The most
recent time information received is stored in an internal time memory.
This time is then kept by a high-precision 32 kHz quartz oscillator until
the next time your watch is synchronised. The radio-controlled time
synchronisation function of your Junghans Mega Futura radio-control-
led watch not only ensures total time accuracy, but also automatically
switches (at night) from winter time to daylight saving time (Europe
and North America) and vice-versa when reception is available. The
Junghans Mega Futura time zone adjustment enables you to set your
watch to the relevant local time when travelling in countries in other
time zones.
