2. Readiness for use
So that your watch is always ready for use, you should make sure
that does not run low on power. The watch regularly checks to see
if it has sufficient battery power. If it no longer has enough (e.g.
the battery has run out or ambient temperature is too low, impair-
ing battery performance), the second hand stops at the 12 o’clock
position. Whatever display is set at that time on the LCD also then
flashes, alternating with the letters ’Lo’. If the battery does not
recover (e.g. through an increase in the ambient temperature), you
should take the watch as soon as possible to your specialist retailer
to have the battery changed, or send it to have this done to the
Junghans Service Centre.
Battery type: CR 1620
Please note that manual time synchronisation is not possible
when battery power is low. Too much power would be needed.
With good reception, the Junghans Mega MF thus always shows
the perfectly correct time within any of these four transmission
areas. Every day at 2am and 3am by the analogue display, the
Junghans radio-controlled watch automatically synchronises itself
with the DCF77,WWVB, JJY40 and JJY60 time signal transmitters.
If reception fails due to interference (e.g. stormy weather, electrical
appliances), the Junghans Mega MF radio-controlled watch will pick
up the signal automatically at the same time the following day.
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
32kHz quartz movement until the time is synchronised again. The
radio-controlled time synchronisation of your Junghans Mega MF
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).
If you travel to a country in a different time zone, changing to the
appropriate time for that area is made simple by the time zone
switching function of your Junghans Mega MF radio-controlled
watch.
