3. Automatic time synchronisation
The fully auto atic ti e synchronisation takes place daily using the DCF77
(Europe) trans itter with CET (Central European Ti e) at both 2:00 und 3:00
hours, as well as CEST (Central European Su er Ti e) at 3:00 und 4:00
hours depending on the current local ti e. With the trans itter WWVB
(North A erica) and JJY40 respectively JJY60 (Japan) at 2:00 and at 3:00 hours
depending on the current local ti e.
The display switches itself off auto atically when the auto atic synchronisa-
tion co ences. The display will re ain switched off for the whole of the syn-
chronisation period ( axi u 9 inutes) or until the procedure is anually
discontinued. The auto atic ti e synchronisation procedure can be disconti-
nued with the use of the T1 button. With the use of one of the buttons ranging
fro T2 to T5, it is possible to display the current ti e during the synchroni-
sing procedure by keeping the button depressed or, by pressing the T5 lighting
button which will display the ti e for the duration of the illu ination. Hereby,
the current hour, inutes and seconds as well as weekday, day, onth and
year will be displayed.
The date is also auto atically adjusted by the ti e signal, and this function
also takes 29 February into consideration during leap years.
If, within a 24-hour period, all atte pts to receive a signal fail to correctly syn-
chronise the watch, the reception indicator increases by 1 point (see chapter 6,
”Description of the reception indicator ode”). The indicator increases by 1
point for every further day that a signal is not successfully received. On days
when the watch has not been synchronised ti e is kept with the accuracy of
a quartz watch using the internal ti e e ory. The watch will be synchroni-
sed as soon as a signal is successfully received.
Recommendation: The best conditions for reception of the ti e signal at night
exist when the watch is not being worn and is not placed near to electronic
devices, obile telephones or cordless telephones.
4. Functions
The Junghans Mega 1000 has a variety of functions that are shown in the
display. The watch is operated using the five buttons above and below the
display as well as on the side of the watch (the button desig nations are shown
in the overview located in the foldout front cover).
4.1 Time display modes
The following five ti e display odes are available.
In these odes the watch cannot be adjusted using the T1 or T2 buttons. Only
T3 (to switch between Ti e, Stopwatch, Countdown Ti er and Alar odes)
and T4 (to select ti e display ode) are active so that the watch settings can-
not be accidentally changed.

For the USA’s WWVB time signal transmitter the following specific feature
applies:
After a successful trans itter call or restart, your Junghans Mega 1000
always reads in Pacific Standard Ti e. Due to the non-unifor changeover
fro su er to winter ti e and the differing ti e zones in the individual
US states, you are given the opportunity to adjust winter ti e, su er ti e
and ti e zone settings (see 8.1) anually. If, due to where you are, the ti e
zone or su er / winter ti e that you have set differs fro PST, it is never-
theless retained during any subsequent trans itter call or auto atic syn-
chronisation.
