Operating Instructions.
Connect the battery charger to the socket outlet without
a battery inserted. The yellow LED indicator lights up and
signals operational readiness.
Insert the battery.
The monitoring of the charge procedure is signalled by a
flashing green light.
The end of the charge procedure is indicated by continu-
ous green lighting.
The rapid charging starts automatically as soon as the bat-
tery temperature is within the charge-temperature range
of 5 °C to 45 °C.
In case of an extremely deep discharged battery, the
charging procedure may not start until after a delay of
several minutes after sliding on the battery.
When lithium-ion batteries are fully charged, the battery
charger switches off automatically.
If the battery becomes discharged within a short time
despite being charged correctly, it has reached the end of
its service life.
