There are two batteries in the appliance and respec-
tively 2 LED operating status displays. Both can show
the colours green, orange and red.
LED green: U= >22.00 V
LED orange: U= >20.00 V
LED red: U= <20.00 V
Both battery voltages are measured after switching
on the appliance. The depleted batteries are added
and the LED assigned to is will illuminate green when
the batteries are fully charged.
The second battery pack is not added until the first
one has been discharged and switched off. If the sec-
ond battery pack is not charged or if the appliance is
operated by battery power only, the respective LED
will light up red immediately after you turn it on.
As soon as the active batteries do not reach the de-
fined voltage level, the LED will switch to orange. If
the batteries have been depleted all the way down to
the deep discharge level, it will be switched off. The
respective LED will now illuminate in red and the sec-
ond battery pack will be switched on/added. Its
charging status will be displayed via the LED as-
signed to it according to its violtage level.
After the second battery pack has been depleted,
both LEDs will light up red; the appliance will auto-
matically switch off after 30 seconds.
