Condensers in the appliance may still be charged, even if the appliance was disconnected from
all voltage sources.
Repairs may only be conducted by experts who are familiar with the associated risks respec-
tively the pertinent regulations.
If you need to change a fuse, make sure that you only use fuses of the stated type and with the
stated nominal amperage for replacement.
Repairing fuses or bridging the fuse holder is not permitted!
When working on live appliances, only use tools expressively permitted for such work.
Only a trained expert may replace a damaged power connection cable.
General
Accumulators consist of two electrodes that are placed in an electrolyte; this makes an accu-
mulator a chemical element. Chemical processes take place on the inside of this element. As
these processes are reversible, accumulators can be recharged.
Charging the accumulator requires the so-called charging voltage, which must be higher than
the cell voltage. In addition, more energy must be provided during charging (mAh) than what
can be used again later on. This relation between supplied and used energy is called degree of
effectiveness.
The usable capacity, which strongly depends on the discharge current is decisive for the state
of the accumulator. The supplied charge cannot be used as rate, as a part of it is lost (e.g.
transformed into heat).
The capacity details stated by the manufacturer are the maximum theoretical charge quantity
the accumulator can give off. That means that an accumulator with 2000 mAh can theoretically
provide a current of 1000 mA (= 1 ampere) for a period of two hours. This value strongly
depends on many factors (condition of the accumulator, discharge current, temperature, etc.).
The term "C rate" is very common with chargers. The C rate is the current value that is normal-
ly stated for charging and discharging. Here this current value in ampere corresponds to the
nominal capacity in ampere-hours, meaning with an accumulator with 2000 mAh, 1C = 2.0 A.
Please note that the usable capacity of an accumulator strongly depends on the discharge cur-
rent. The lower the discharge current, the higher the usable capacity.
With this charger, a discharge current of 850 mA can flow at the beginning of a discharge
process: for an accumulator with 850 mAh, 850 mA are already 1C, while this is only C/2 for an
accumulator with 1700 mAh. Therefore, the 1700 mAh accumulator is going to reach its 1700
mAh easier than the 850 mAh accumulator its 850 mAh.
Meanwhile, renowned manufacturers state the capacity of an accumulator with C/3, meaning
that e.g. a 2500 mAh accumulator reaches these 2500 mAh with a discharge current of 850 mA
(= approx. C/3). However, if a manufacturer states a discharge current of C/10 for a 2500 mAh
accumulator (= 250 mA), one can assume that this accumulator cannot give off 2500 mAh with
a discharge current of 850 mA. This makes the C/10 accumulator the inferior one.
Accumulators also discharge over time. This characteristic is called spontaneous discharge.

Overview
Contrast
The reading angle of the display depends on the location of the charger. Depending on the
angle of view, you can adjust the good readability of the writing with the menu "DISPLAY CON-
TRAST" with a high or low position of the charger.
POWER MODE
If no accumulator is inserted, you can activate the POWER mode: this doubles the charge cur-
rent for the eight round cells.
The inserted micro accumulators have to have a minimum nominal capacity of 700 mAh,
MIGNON min. 2000 mAh and BABY accumulators at least 4000 mAh for the POWER mode!
You can only charge MONO and BABY accumulators in slot 1 to 4 while the device is in POW-
ER mode.
Procedure
Insert the accumulator. If the accumulator is not detected automatically, check the polarity.
Then set the program with the two SELECT buttons and conform with OK.
In case of a wrong program, take out the accumulator, reinsert it and enter the program anew!
You can select the charge types CHA, DIS, CHK, CYC and ALV.
At the start of the program, the fan (which is only running slowly) switches to maximum capac-
ity and becomes perceivably louder.
READY (RDY) appears in the display when the charging of the accumulator is done. Now you
can take out the accumulator.
The three buttons serve to display the individual slots during the processing of a program and
to adjust the display contrast.
In case of power failure or when the device is unplugged or switched off, the data and settings
are preserved as long as the accumulator is not taken out.
ERROR (ERR)
This appears if a MONO or BABY accumulator was inserted in slots 5 to 8 in POWER mode, if
a (non-rechargeable) battery was inserted or if another error has occurred.
BREAK (BRK)
The total charge current of 16 A was exceeded. The accumulator is charged automatically as
soon as another accumulator is finished.
Technical Data
This charger serves exclusively for charging up to eight nickel/cadmium respectively
nickel/metal hydride round cell accumulators size mono, baby, mignon and micro simultane-
ously.
Additionally, you can charge two 9V block accumulators made of nickel/cadmium respectively
nickel/metal hydride. These accumulators may consist of 6, 7 or 8 cells.
