Continuously illuminated green battery charge level
indicator (4)
The continuous light of the green battery
charge level indicator (4) signals that the bat-
tery is fully charged.
The battery can then be removed for immediate use.
When there is no battery connected, the continuous light of
the battery charge level indicator (4) indicates that the
mains plug is plugged into the mains socket and that the
charger is ready to be used.
Continuously illuminated red battery charge level
indicator (3)
The continuous light of the red battery charge
level indicator (3) shows that the temperature
of the battery is outside of the permitted char-
ging temperature range, see section "Technical
data". The charging process begins as soon as the permitted
temperature range has been reached.
Flashing red battery charge level indicator (3)
The flashing light of the red battery charge
level indicator (3) signals that the charging
process has been interrupted by a different
fault, see section "Errors – causes and correct-
ive measures".

Practical advice
When the charger is used continuously, or for several con-
secutive charge cycles without interruption, the charger may
heat up. This is, however, harmless and does not indicate
that the charger has a technical defect.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
