Display while in service
Charge level display during opera-
tion (empty–full):
V W X
A beep sounds when the battery is
nearly empty. The charge level of the
battery is only displayed correctly af-
ter an uninterrupted charging/dis-
charging cycle. You should therefore
not remove the battery unnecessarily
and where possible not finish the
charging process prematurely.
Getting started
Additional information
The power supply unit heats up when used
for long periods. This is normal and not
dangerous.
If the battery is removed for longer than
30 seconds, the clock must be reset.
