Commissioning  
Notice:  
Ensure that the batteries are inserted into the  
charging slots in accordance with their polarities.  
Otherwise, the batteries will not be charged.  
• Before taking the Battery Charger into use,  
check that all items are complete/available and  
free of visible damage.  
• Place the Battery Charger on a straight, level,  
scratch and slip resistant surface.  
• Insert the batteries into the charging slots.  
• Press the 9 V Block batteries into the charging  
slot until they audibly engage.  
Notice:  
This appliance is equipped with non-slip rubber feet.  
As furniture surfaces may be made of a variety of  
materials and are treated with many different types  
of cleaning agents, it cannot be completely ruled  
out that some substances contain ingredients which  
may corrode the rubber feet and soften them.  
If possible, place an anti-slip material under the device.  
Between 1-6 batteries can be loaded individually:  
• 4 x Type C or Type D in the charging slots 1 to 4,  
or  
• 4 x Type AA or AAA in the charging slots 1 to 4,  
with additionally 2 x Type 9 Volt Block batteries  
in the charging slots 5 and 6.  
• The charging process now begins. The Battery  
Charger has an LED for each charging slot. The  
LEDs of the charging slots indicate the charge  
state of the battery they contain.  
• In the first 5 seconds, the Battery Charger  
performs a quick capacity test:  
Compare the technical data with that of your  
current mains power supplier. If they are the  
same, connect the power cable to a mains  
power socket. The LEDs now light up red and  
green. The Battery Charger is now  
ready for use.  
- The LED of the charging slot glows green:  
Capacity over 90 %.  
- The LED of the charging slot blinks green:  
Capacity between 80 % - 90 %.  
Charging batteries  
- The LED of the charging slot glows red:  
Capacity under 80 %.  
- The LED of the charging slot blinks red:  
The battery has not been correctly inserted into  
the charging slot or it is defective.  
Danger!  
Charge exclusively rechargable batteries of the  
types „Ni-Cd“ and „Ni-MH“.  
When the capacity of the battery is determined,  
charging process starts.  
NEVER recharge batteries of other types or non-  
rechargable batteries. These are not suitable for  
recharging. They could irreparably damage the  
Battery Charger and the inserted batteries. There is  
also the danger of a fire as well as an explosion!

The various indicators have the following meanings:  
Automatic charging control/  
Retention charging  
This Battery Charger controls the charging time for  
rechargable batteries of the types Ni-Cd and Ni-MH  
separately. This control is based on the –Δ U  
(„minus Delta U“) calculation.  
-
The LED blinks red and green every second  
(Not for 9V Block batteries):  
The batteries are alternately charged and  
discharged for about 8 minutes. (Refresh-Function:  
Older batteries or those that have been stored for  
a long period will be refreshed.).  
In mathematics, with Delta Δ differences are  
described.  
-
The LED flashes red and green in a 1/2 second  
rhythm: The batteries will be discharged to help  
reduce the memory-effect.  
„Minus Delta U“ in this case means a negative  
voltage difference.  
This charge identification makes itself useful in the  
following effects:  
-
-
The LED glows red constantly:  
The batteries are being charged.  
Should a battery be charged with a constant current,  
its voltage rises continuously. When the battery is  
full, its voltage reaches a maximum and falls lightly  
with further current flow. This light fall in voltage is  
recognised by the charging electronics and the  
charge process is terminated. The Battery Charger  
automatically switches to „Retention charging“.  
This means that the batteries are no longer being  
charged with continuous power, but with short power  
impulses instead. This counteracts the process of  
self-discharge, thus retaining the batteries in a fully  
charged condition.  
The LED glows green constantly:  
The batteries are fully charged and the Battery  
Charger has switched over to trickle charge.  
Warning!  
The batteries could become hot during charging.  
NEVER touch hot batteries! There is a danger of  
being burnt!  
• Remove the power cable of the Battery Charger  
from the plug socket and allow the batteries to  
cool down.  
Afterwards you can remove the charged batteries  
from the Battery Charger.  
Timer control  
In addition, this charger is fitted with a timer control,  
which after 15 hours automatically switches over to  
trickle charge. This serves as additional protection  
against overcharging should the charge terminating  
device not respond, due to a possibly defective  
battery.  
Calculating the average charging time  
Dependant on the type, age and remaining battery  
charge, hence the charging process takes different  
lengths of time. The average charging times can be  
calculated using the following formula.  
Note, however, that the times calculated are only  
indicative.  
Current time (Min.) =  
Capacity of the battery (mAh) x 1,5 x 60  
Charging current of the appliance (mA)

Troubleshooting  
Cleaning  
The Battery Charger displays no functions  
• Check to see if the power cable is correctly  
inserted into the power socket.  
• Check to see if the power socket is „live“. To do  
this, connect a different, functioning electrical  
appliance to the socket.  
ƽ Danger! Disconnect the power cable before  
cleaning. There is the risk of receiving an  
electric shock! Ensure that moisture cannot  
penetrate into the device during cleaning!  
Clean the housing of the Battery Charger only with  
a dry cloth. For stubborn soiling use a slightly damp  
cloth.  
Under no circumstances use moisture to clean the  
interior of the charger. Instead, use a soft and clean  
brush to clean the insides. DO NOT use abrasive or  
chemical cleaning agents.  
The inserted batteries are not being charged  
• Check that the batteries are being inserted in  
accord with their polarity.  
• Check that batteries suitable for charging have  
been inserted into the Battery Charger. Suitable  
for charging are exclusively rechargable Ni-Cd  
and Ni-MH batteries of the types AAA/AA/C/D  
and 9 V Block batteries.  
• Remove the power cable from the power socket  
and allow the appliance to cool down, as the  
temperature monitoring has possibly activated  
itself. Temperature monitoring ensures that the  
charging process is broken off as soon as a bat-  
tery reaches an excessively high temperature.
