Operational Requirements - Junghans Mega 1000 Manual

This means that within range of one of these 4 transmitter stations your
Junghans Mega 1000 will display the exact time when reception conditions
are adequate.
Junghans radio-controlled wristwatches automatically synchronise themsel-
ves every day with the DCF77, WWVB, JJY40 and JJY60 time signal transmitters.
If your Junghans Mega 1000 radio-controlled watch is unable to receive a sig-
nal due to interference (e.g. thunder storms, electronic devices, lighting dim-
mer switches) it will automatically attempt to receive a signal the following
day at the same time.
The time can also be synchronised manually by calling a transmitter e.g. from
a place with better reception.
The most recent time information received is stored in an internal time memo-
ry. 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
1000 radio-controlled 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 1000 time zone adjustment function enables you to set
your watch to the relevant local time when travelling in countries in other time
zones.

Make sure that the battery has enough power to ensure the continuous
operation of your watch.
The watch regularly checks whether sufficient battery power is available. If the
battery is low on power (empty battery or low ambient temperature affecting
battery performance) then a battery indicator appears in the LCD display. If the
battery does not recover (e.g. due to higher ambient temperature) you should
bring the watch to your specialist retailer or send it to the Junghans Service
Center within a few weeks to have the battery replaced.
Battery type: CR 1620 – average service life: approx. 2 years
Please ensure that the battery is disposed of appropriately and in accordance
with the legal regulations.
