1. Intended use
This appliance is intended for charging NiCd / NiMH
rechargeable batteries of Size Micro AAA, Mignon AA, Baby
C, Mono D
and 9V battery packs, for personal and house-
hold purposes.
It is not intended for charging commercial type batteries
(even rechargeable types), or lithium-ion batteries, or for
use in commercial or industrial applications.
Never load commercially available non-chargeable
batteries into the appliance – these can overheat and
explode. Risk of injury!

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.
•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.
•Never expose the appliance to other sources of heat,
such as direct sunshine or heaters. This will prevent the
batteries from overheating prematurely.
•If you are charging a number of batteries at the same
time: Always insert only batteries that are similar, i.e.
batteries of the same type, same level of charge, same
size and same capacity. This will avoid some of the
batteries becoming fully charged and overheating while
the others are still charging.
•Set up the appliance in dry rooms only, never in humid
areas. Otherwise there could be danger of death from
electric shock.
•If the appliance is not working or is damaged, it should
no longer be used. Have it repaired by customer service.
•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 ele-
ments inside. Warning! Risk of accident!
•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 dan-
ger for children, who might put the batteries in their
mouth (they contain poisonous heavy metals), or short-
circuit them while playing with them.

4. Charging batteries
Danger: Only charge batteries identified by the letters
"NiCd" or "NiMH" .
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 NiCd/NiMH battery chargers,
they can overheat and explode.
a) Inserting batteries
•Place the batteries the right way up, as indicated in the
charging slots. Otherwise the charging process cannot
start.
NiCd 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.
NiMH are not susceptible to the "memory effect".

b) Test the batteries first!
If you do not know how charged or discharged your
batteries are, you can test them as follows:
Move the switch to the far left, to the position with
the "partly charged batteries" symbol.
•Then, connect the power plug to the power socket.
The test indicator lightat 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.
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.

d) Charging batteries
If you have inserted the batteries the right way up,
as described at paragraph a) ...
move the switch to the center, to the position with
the "Charge" symbol, and ...
•connect the power plug to the power socket.
If all batteries have been placed correctly, the charge
indicator LED lights up at each charging slot.
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.
•Only charge with the cover closed. This will provide
sufficient protection against flying battery parts in the
event of an explosion due to overheating.

c) Discharge NiCd batteries first
NiCd batteries that are not fully discharged should be
discharged first, to avoid the possibility of "memory
effects".
If you have inserted up to 4 NiCd batteries,
move the switch to the far right, to the position
with the "Discharge" symbol.
•Connect the power plug to the power socket.
Allow the NiCd batteries to discharge until the
test indicator light is barely lit, meanwhile testing
the batteries a few times.
Important: Do not allow NiCd 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 feature is only available at the four charging
slots for 1.2 V batteries – not for 9 V batteries.

e) Keep to the charging time!
The best protection against battery overheating is not to
exceed the proper charging time. If you wish to calcula-
te 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:
1.2V NiCd battery 300 mAh 500 mAh 1200 mAh
Charging time: 1.5-2 hrs. 3 hrs. 9 hrs.
1.2V NiMH battery 650 mAh 1700 mAh 3000 mAh
Charging time: 3 hrs. 9 hrs. 15 hrs.
9V NiCd battery 100 mAh
Charging time: 5-11 hrs.
9V NiMH battery 150 mAh
Charging time: 8-15 hrs.
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.
All charging slots and 9 V 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.
f) 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 available for the 9V connections only.
Turn the knob to about the time required (you can
determine this time by referring to the table opposite).
At the end of the charging time, the appliance switches
over to trickle charge, and the green LED indicator at
the "Battery" symbol is fully lit.
If you do not want to use this function, set the knob to
the maximum charging time of "15 h".

5. Taking out batteries
When charging is complete and you wish to take out the
batteries, ...
•first disconnect the power plug from the
power socket,
• wait until the batteries have cooled.
•take out the batteries.
6. Cleaning and Care
Clean the appliance only when the plug has been discon-
nected from the power socket and all the batteries have
been taken out.
•Clean the appliance only with a dry cloth. Never use
cleaning agents or solvents. These may cause damage
to the appliance, and particularly to the labelling and
plexiglas cover.
•The terminals do not require cleaning, as they are chro-
me-plated and therefore dirt resistant.
7. Storage
If you are not going to use the appliance for a long period,
disconnect the plug from the power socket and remove all
batteries from the charging slots.
Caution: If you do not take out the batteries, deposits
can accumulate over time at the terminals, depending on
the quality of the battery. Batteries can also leak and
damage the appliance.
•Store the appliance in a dry place.
8. Disposal
Before disposing of the appliance, take out any batteries
remaining inside. These should not be disposed of with the
household waste. Take the appliance and batteries to your
dealer, or to a suitable recycling center.
