Automatic Battery Recharge
Automatic battery recharging begins after a normal
shut-down. The recharging status is shown
graphically on the Operation Module display as a
percentage. The LEDs light up in reverse sequence;
see „Battery level indicator“ on page 12.
Depending on the battery level, recharging may take
up to 4 hours. When recharging is completed, the
LEDs go out.
