8.1 Restarting after a complete discharge of the power store
Following a complete discharge of the energy store the Junghans mul-
ti-frequency radio-controlled solar watch must be placed in a source of
light in order to recharge the energy store. During the charging process
two bars ash in the LC display [--]. A restart is carried out automati-
cally as soon as the charging process is completed. The hands move to
the 12:00 position and the watch begins to receive the time signal. The
display goes o in the LC display. In the case of successful reception the
watch automatically adjusts to the correct time after a few minutes.
If the watch has still not received a time signal after 50 minutes, the
reception procedure will be discontinued to save energy and repeated
every 6 hours. The hands remain in the 12:00 position and two ashing
bars are displayed in the LC display [--] every two seconds. To receive
a time display in spite of this the watch can be set to the current time
manually using the quartz mode. The watch then continues to run
with the accuracy of a quartz watch.
To enter the quartz mode press button T1. The watch is now in quartz
mode (see chapter 6 .3).
