•
If the appliance is not working or is damaged, it should
no longer be used. Have it repaired by customer service.
2. Safety instructions!
•
Never leave the appliance to charge unsupervised.
Batteries become hot once they are fully charged.
Overcharged or faulty batteries can overheat and
explode.
If the power cord is damaged: The power cord cannot
be repaired – have it replaced by customer service
before using the appliance again.
•
•
Never open the casing, there are no operating
elements inside. Warning! Risk of accident!
•
Never touch batteries when they are hot – they might
explode while they are being taken out. First discon-
nect the appliance from the power supply and allow
the batteries to cool before taking them out.
Do not allow children or elderly persons to play with
the appliance unsupervised, since these are not always
able to assess the dangers correctly. Batteries can
represent a considerable danger for children, who
might put the batteries in their mouth (they contain
poisonous heavy metals), or short-circuit them while
playing with them.
•
•
Never expose the appliance to other sources of heat,
such as direct sunshine or heaters. This will prevent
the batteries from overheating prematurely.
Set up the appliance in dry rooms only, never in humid
areas. Otherwise there could be danger of death from
electric shock.

b) Test the batteries first!
4. Charging batteries
If you do not know how charged or discharged your
batteries are, you can test them as follows:
Danger: Only charge batteries identified by the letters
"Ni-Cd" or "Ni-MH" .
Never charge other types of batteries, even if these
are "rechargeable". Such batteries require a quite different
type of technology!
If you place these batteries in Ni-Cd/Ni-MH battery
chargers, they can overheat and explode.
ᕡ Move the switch to the far left, to the position with
the "Test"
symbol.
ᕢ The test indicator light at the symbol
is lit brightly
if the battery is sufficiently charged. If the test indicator
light is lit only faintly or not at all, then the battery is
almost completely discharged or flat.
a) Inserting batteries
Note: Only insert the battery in the slot on the far left is
tested. If you would like to test the other batteries as well,
they must be inserted one after the other into this slot.
The test function is not available for 9V single block
batteries!
•
Place the batteries the right way up, as indicated in the
charging slots. Otherwise the charging process cannot
start.
Ni-Cd batteries should only be recharged when they are
almost completely discharged. Otherwise, a "memory
effect" is created, where the batteries reduce their
capacity to the lower level at which they are actually
used. Ni-MH are not susceptible to the "memory effect".

c) Discharge Ni-Cd batteries first
d) Charging batteries
Ni-Cd batteries that are not fully discharged should be
discharged first, to avoid the possibility of "memory
effects".
If you have inserted the batteries the right way up,
as described at paragraph a) ...
ᕤ move the switch to the center, to the position with

with the "Discharge"
symbol.
ᕥ If all batteries have been placed correctly, the charge
indicator LED lights up at each charging slot.
ᕢ Allow the Ni-Cd batteries to discharge until the
test indicator light is barely lit, meanwhile testing
the batteries a few times. For this, push the switch all
the way to the left, into the position with the symbol
„Test“.
Danger! If a charge indicator LED is not lit, even though
the battery has been correctly inserted, then the battery is
faulty. Do not, in any circumstances, attempt to charge
a faulty battery. A faulty battery can overheat and then
explode.
Important: Do not allow Ni-Cd batteries to become
completely discharged, as this may ruin them. Therefore,
do not allow the batteries to discharge until the test
indicator light goes off completely. The discharge function
in the four charging shafts is available for 1.2 V batteries
only – not for 9V single block batteries.
•
Only charge with the cover closed. This will provide
sufficient protection against flying battery parts in the
event of an explosion due to overheating.

e) Keep to the charging time!
All charging slots and 9V connections have separate char-
ging current controls. You can therefore charge completely
different batteries at the same time – provided you observe
the different charging times, required for batteries with
different capacities.
The best protection against battery overheating is not to
exceed the proper charging time. If you wish to calculate
the time exactly, please refer to the technical data for
information about the charging current required. You can
take the values in the following table as a rough guide:
f) Calculation of the Charging Time
1.2V Ni-Cd battery 300 mAh
Charging time: 2 hrs.
800 mAh
4 hrs.
1800 mAh
10 hrs.
Battery Capacity (mAh) x 1.4
Charging Time (h) =
1.2V Ni-MH battery 2100 mAh 3500 mAh
Charging time: 10 hrs. 18 hrs.
9V Ni-Cd battery 100 mAh
Charging time: 11 hrs.
9V Ni-MH battery 200 mAh
Charging time: 22 hrs.
4000 mAh
21 hrs.
Charging Current of the Device (mA)
g) Charging time: Automatic cut-out
If you have loaded four batteries of the same type in the
1.2V charging slots, you can use the automatic cut-out
feature. With this feature, the appliance switches the 1.2V
charging slots over to trickle charge after the pre-selected
maximum charging time. This function is not available
for the 9V connections.
Warning: Batteries with a capacity of not more than
300 mAh should not be charged for more than 2 hours,
as they would become overcharged and overheat.
Not for 9V single block batteries.
