charger). 

Type plates on charger and docking station

To charge the battery safely, the charger must be 

placed on a suitable surface resting on its four 

feet with the LED facing upwards. This is the only 

way to ensure that the hot air around the battery 

warmed during the charging operation can dissi-

pate via the surrounding ventilation slots.

›

2.  Connect the charger to the docking station. The 

LED in the docking station now lights up briefly in 

red and then permanently in green.

›

3.  Put the battery in the holder of the docking 

station. The battery and charger are connected. The 

LED in the charger lights up in green.

4.  The charging operation starts. The LED in the 

charger now lights up green. The battery LEDs light 

up one by one to indicate the progress of the charg-

ing operation. The battery is charged in five stages. 

When charging of one stage is in progress, the cor-

responding LED flashes. If this stage has been fully 

charged, the LED will light up permanently. Now 

the next LED will begin to flash. 

After all five LEDs have gone out, the battery is 

fully charged.

›

5.  If the LED of the charger flashes red permanent-

ly, a charging fault has developed. 

Take the battery out of the charger, then put it back 

in. The charger tests the battery and performs  

readjustments, if required. If the LED on the charger 

still flashes, take the charger and battery to your 

specialist dealer. He will test the devices and  

replace them, if required.

6.  To save power, pull the charger plug out of the 

socket once the charging operation is complete.
