Retention charge
As described under programmes, this appliance
features the automatic retention charge. Depending
on the voltage drop of the battery, caused by self-
discharge, the appliance reacts with different charge
currents.
The battery can remain connected to the charger
for longer periods of time.
Appliance protection function
The charger switches the electronics off and switches
the system instantly to the basic setting, as soon as
there is an abnormal situation, such as short circuit,
critical voltage drop during charging, broken circuit
or swapped connection of the connector clamps is
detected.
Should the appliance become too hot during charg-
ing, the output current is automatically reduced.
This protects the appliance from damage.
Maintenance and care
Before you carry out any work
on the battery charger always pull the mains
plug out of the mains socket.
The appliance is maintenance-free.
Do not under any circum-stances use solvents
or other aggressive cleaning agents.
Clean the plastic surfaces of the device with
a dry cloth.
