3. Intended Use
The charger "V-Charge 200 Duo" has two independent charge/discharge channels that each have a two-line lit display
and four operating buttons.
The charger is used to charge and discharge rechargeable batteries of the type NiMH/NiCd (1 - 15 cells), LiPo/LiIon/
LiFe/LiHV (1 - 6 cells) and lead batteries (1 - 10 cells, 2 V - 20 V).
The charging current for channel 1 can be set between 0.1 A and 10.0 A. The charging current for channel 2 can be
set between 0.1 A and 5.0 A (each depending on the cell number/rechargeable battery voltage). The maximum total
charging output is 200 W (each channel max. 100 W).
The discharging current for channel 1 and 2 can be set between 0.1 A and 5.0 A (depending on the cell number/
rechargeable battery voltage). The maximum discharge output for each channel is 15 W.
For each of the two charge/discharge channels, there is a connection for a temperature sensor available for battery
monitoring (not enclosed, can be ordered as an accessory).
For multi-cell lithium rechargeable batteries, each charge/discharge channel has a separate balancer. Matching bal-
ancer boards are included in the delivery.
The charger has an integrated mains unit to permit operation on mains voltage (230 V/AC, 50/60 Hz). The charger
may, however, also be alternatively operated on a stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle
lead battery or a suitable mains adapter).

• If the mains cable or charger are damaged, do not touch it. Danger to life from electric shock!
First switch off the mains voltage for the mains socket to which the mains cable is connected (switch
off the corresponding circuit breaker or take out the fuse, then switch off the fault interrupter protection
switch (FI circuit breaker) so that the mains socket is separated from the mains voltage on all poles).
Only then unplug the mains unit from the mains socket.
If the charger is damaged, stop operating it. Take it to a specialised workshop or dispose of it in an
environmentally friendly way.
If the mains cable is damaged, dispose of the damaged mains cable in an environmentally compatible
way. Do not use it anymore. Replace it with a new mains cable of the same specications.

7
c) Location for Installation
• The charger is intended for dry indoor use only. It must not become damp or wet. Never set it up near a
bathtub, shower or similar!
If the charger is operated via the mains cable, there is danger to life from electric shock in case of mois-
ture/wetness on the charger/mains cable!
• Avoid direct sun irradiation, strong heat or cold. Keep the charger away from dust and dirt. The same
applies to any rechargeable battery that may be connected.
• Do not operate the charger inside of rooms or in bad ambient conditions where ammable gases, va-
pours or explosive dust may be or are present! There is a danger of explosion!
• Choose a solid, at, clean and sufciently large surface for the charger. Never place the charger on a
ammable surface (e.g. carpet, tablecloth). Always use a suitable, non-ammable, heatproof surface.
• Keep the charger away from ammable or easily inammable materials (e.g. curtains).
• Never cover the ventilation slits. There is a danger of overheating or re. Never push any objects into the
ventilation slots of the charger; There is a danger to life from electric shock! Never impair the function
of the integrated fan.
• Do not place the charger on any valuable furniture surfaces without using a suitable protection. Other-
wise, scratches, pressure points or discolourations are possible. The same applies to the rechargeable
battery.
• Do not use the charger inside a vehicle.
• The charger must only be set up, used or stored in places that are not accessible to children. Children
may change the settings or short-circuit the rechargeable battery/battery pack, which can lead to an
explosion. Danger to life!
• Avoid setup in direct proximity of strong magnetic or electromagnetic elds, transmitter aerials or HF
generators. This can affect the control electronics.
• Ensure that the cables are not crushed or damaged by sharp edges. Never place any objects on the
cables.
• Do not place any containers lled with liquid, vases or plants, on or next to the charger/mains cable.
When these liquids get into the charger (or the plug connections of the mains cable), the charger will be
destroyed and there is a most severe danger of potentially fatal electric shock or re.
If the charger is operated via the mains cable, rst switch off the mains voltage for the mains socket to
which the mains cable is connected (switch off the corresponding circuit breaker or take out the fuse,
then switch off the fault interrupter protection switch (FI circuit breaker) so that the mains socket is
separated from the mains voltage on all poles). Only then unplug the mains plug of the mains cable from
the mains socket.
If the charger is operated via the DC input (11 - 18 V/DC), disconnect the charger from the voltage/
power supply.
Then disconnect the connected rechargeable battery from the charger. Do not use the charger again -
bring it to a specialist workshop.

d) Operation
• The charger may be operated either via the mains voltage (230 V/AC, 50/60 Hz) or via a stabilised direct
voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable mains adapter).
Use only one of the two connection types, but never both at once. This may damage the charger.
• Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.) while
you are working with the charger or batteries. A short-circuit at the rechargeable battery or charging
cable poses a danger of burns and explosion.
• Do not operate the product unattended. Despite a considerable number of protective circuits, it is impos-
sible to exclude the possibility of malfunctions or problems during the charging process.
• Ensure that there is sufcient ventilation during operation. Never cover up the charger. Leave enough
of a distance (at least 20 cm) between charger and other objects. Overheating causes a danger of re!
• The charger must only be used to charge (or discharge) rechargeable batteries of types NiMH, NiCd,
LiIon/LiPo/LiFe/LiHV and lead batteries. Never charge any other rechargeable battery types or non-
rechargeable batteries. There is great danger of re or explosion!
• Always connect the charging cable to the charger rst. Only then must the rechargeable battery be con-
nected to the charging cable.
When disconnecting, proceed in reverse order - rst disconnect the rechargeable battery from the charg-
ing cable, then the charging cable from the charger.
If the order is chosen incorrectly, there may be a short-circuit of the charger plugs; there is a danger of
re and explosion!
• Never connect several charges to each other.
• The charger has two charging channels that are independent of each other, so that up to two recharge-
able batteries/rechargeable battery packs can be charged (or discharged) at once. However, only con-
nect a single rechargeable battery/rechargeable battery pack to each of the two charging channels.
Never connect the charging channels to each other!
• Only operate the product in moderate climate, never in tropical climate. For more information on accept-
able environmental conditions, see the chapter "Technical Data".
• Never operate the device immediately after it was taken from a cold room to a warm room. The resulting
condensation may lead to malfunctions or damage!
Let the product reach room temperature before taking it into operation again. This may take several
hours!
• Avoid operation in direct proximity of strong magnetic or electromagnetic elds, transmitter aerials or HF
generators. This can affect the control electronics.
• If you have reason to believe that the device can no longer be operated safely, disconnect it immediately
and make sure it is not operated unintentionally.
Disconnect the charger from the voltage/current supply. Do not use the product any more after this, but
take it to a specialised workshop or dispose of it in an environmentally compatible manner.
• It can be assumed that operation without danger is no longer possible if the device has any visible
damage, the device no longer works, after extended storage under unsuitable conditions or after difcult
transport conditions.
• Keep the entire product at a dry, cool, clean site that is not accessible to children.

6. Rechargeable Battery Notes
Although use of rechargeable batteries in everyday life is a matter of course today, there are many
dangers and problems. In particular, with LiPo/LiIon/LiFe/LiHV rechargeable batteries with their
high energy content (in comparison with conventional NiCd or NiMH rechargeable batteries), vari-
ous regulations must be observed in order to avoid the danger of explosion and re.
For this reason, always ensure that you have read and understood the following information and
safety information when handling rechargeable batteries.
If the manufacturer of the rechargeable battery has provided any other information, read it carefully
and observe it!
a) General
• Rechargeable batteries are no toys. Always keep batteries/rechargeable batteries out of the reach of
children.
• Do not leave rechargeable batteries lying around openly. Children or pets may swallow them. If swal-
lowed, consult a doctor immediately!
• Rechargeable batteries must not be short-circuited, taken apart or thrown into re. There is a risk of re
and explosion!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin when touched
without the use of adequate protective gloves.
• Never recharge normal (non-rechargeable) batteries. There is a risk of re and explosion!
Non-rechargeable batteries are meant to be used once only and must be disposed of properly when
empty.
Only charge rechargeable batteries intended for this purpose. Use a suitable battery charger.
• Batteries must not get damp or wet.
• Place the charger and battery on a non-ammable, heat-resistant surface (e.g. stone tiles). Maintain
enough distance from ammable objects. Leave enough distance between the charger and the re-
chargeable battery - never place the rechargeable battery on the charger.
• As both the charger and the battery heat up during the charge/discharge procedure, it is necessary to
ensure sufcient ventilation. Never cover the charger or the rechargeable battery!
• Never use battery packs made up of different cells.
• Never leave the charging/discharging batteries unattended.
• Never recharge a battery directly in the model. Always remove the rechargeable battery from the model
for recharging.
• Always observe correct polarity (plus/+ and minus/-) when connecting the rechargeable battery to your
model or charger. Connecting the battery incorrectly will not only damage the model but also the re-
chargeable battery. There is a risk of re and explosion!
This charger has a mechanism that protects against connecting the poles incorrectly. Nonetheless, it is
possible that an incorrectly connected battery may lead to damage in certain situations.

10
• The charger has two charging channels that are independent of each other, so that up to two recharge-
able batteries/rechargeable battery packs can be charged (or discharged) at once. However, only con-
nect a single rechargeable battery/rechargeable battery pack to each of the two charging channels.
Never connect the charging channels to each other!
• If the product is not to be used for an extended period of time (e.g. storage), disconnect any connected
rechargeable battery from the charger and disconnect the charger from the voltage/current supply.
The charger has no mains switch. If you operate the charger via the mains cable, pull the mains plug
from the socket when you no longer need the charger.
• Do not charge/discharge any battery that is still hot (e.g. caused by high discharging current from the
model). Allow the rechargeable battery to cool down to room temperature before attempting to charge
or discharge it.
• Never damage the exterior cover of a battery. There is a risk of re and explosion!
• Never charge/discharge damaged, leaking or deformed batteries. This can result in a re or explosion!
Dispose of any unusable rechargeable batteries in an environmentally compatible fashion. Do not con-
tinue to use them.
• Remove the battery from the charger when it is fully charged.
• Recharge the rechargeable batteries about every 3 months. Otherwise, so-called deep discharge may
result, rendering the rechargeable batteries useless.
• Keep rechargeable batteries in a suitable location. Use a smoke detector in the room. The risk of re (or
the occurrence of toxic smoke) cannot be excluded. Special rechargeable batteries for the model con-
struction area are subject to great stress (e.g. high charging and discharging currents, vibrations, etc.).
b) Additional Information about Lithium Batteries
Modern batteries with lithium technology do not only have a clearly higher capacity than NiMH or NiCd
rechargeable battery packs but they also have a considerably lower weight. This makes this type of re-
chargeable battery very interesting for application in model construction; so-called LiPo batteries (lithium-
polymer) are often used here.
Rechargeable lithium batteries require special care when charging/discharging, as well as during operation
and handling.
For this reason, we would like to provide you with some information in the sections below about the dangers
and how you can avoid them, thus helping such batteries to maintain their performance for an extended
period of time to come.
Additionally observe chapter 6. a).
• The outer shell of many rechargeable lithium batteries is only made of a thick foil and therefore very
sensitive.
Never destroy or damage the battery, never let the battery fall and do not pierce the battery with any
objects! Avoid any mechanical strain on the battery; never pull the connection cables of the battery!
There is a risk of re and explosion!
These guidelines must also be observed when the battery is inserted into the model or when it is re-
moved from the model.

11
• Ensure that the battery does not overheat during usage, recharging, discharging, transport or storage.
Do not place the battery next to sources of heat (e.g. speed controller, motor), keep the battery away
from direct sunlight. There is a risk of re and explosion if the battery overheats!
The battery must never heat up to more than +60 °C (observe any additional information from the
manufacturer!).
• If the battery is damaged (e.g. after the crash of an aircraft or helicopter model) or the exterior cover is
soaked/has expanded, do not use the battery. Do not charge it anymore. There is a risk of re and explo-
sion!
Handle the battery with care, use suitable protective gloves. Dispose of the rechargeable battery envi-
ronmentally compatibly.
Never keep such rechargeable batteries in an apartment or a house/garage anymore. Damaged or
bloated lithium rechargeable batteries may catch re suddenly.
• Only use a suitable charger to charge lithium batteries or use the correct charging procedure. Due to a
risk of re and explosion, conventional chargers for NiCd, NiMH and lead batteries must not be used!
Always choose the right charging procedure depending on rechargeable battery.
• When charging a lithium battery with more than one cell, always use a so-called balancer (one is already
integrated into the supplied charger).
• Charge LiPo batteries with a max. charging current of 1C (if not indicated otherwise by the battery
manufacturer!). This means that the charging current may not exceed the capacity value imprinted on
the battery (e.g. battery capacity 1000 mAh, max. charging current 1000 mA = 1 A).
With LiFe, LiIon and LiHV batteries, you must observe the instructions of the battery manufacturer.
• The discharging current must not exceed the value printed on the battery.
For example, if a value of "20C" is printed on a LiPo battery, the max. discharging current is 20 times
the battery’s capacity (e.g. battery capacity 1000 mAh, max. discharging current 20C = 20 x 1000 mA
= 20 A).
Otherwise, the battery will overheat, causing deformation/bloating of the battery or explosion and re!
The printed value (e.g "20C") does not generally refer to the constant current, but to the maximum cur-
rent that the battery is capable of producing in the short-term. The constant current therefore should not
be higher than one half of the given value.
• Observe that the individual cells of a lithium rechargeable battery must not be deep-discharged. A deep
discharge of a lithium rechargeable battery will lead to permanent damage/destruction of the recharge-
able battery.
If the model does not provide protection against total discharge or possess a visual display indicating a
low battery, remember to switch off the model in time.

The voltages in the above table apply to a single cell. The data may deviate depending on manufacturer
(observe manufacturer’s information!).
The max. charging and discharging currents are indicated with the capacity value "C".
A charging current of 1C corresponds to the capacity value imprinted on the battery (e.g. indicated battery
capacity 1000 mAh, max. charging current 1000 mA = 1 A).
Also observe the correct voltage setting for multi-cell battery packs. For example, the individual cells in a
two-cell battery pack may be switched in parallel or in series.
If the maximum permissible charging current for the rechargeable battery is exceeded or a wrong cell
number/voltage setting is chosen, there is a danger of destroying the rechargeable battery. There also is a
danger of re and explosion from the rechargeable battery!
Further notes on the max. charging current and the cell number/voltage can be taken from the data sheets
or the labels of the rechargeable batteries; these data take precedence over the information in the above
table.
Important!
• Never charge battery packs made up of different cells (or cells from different manufacturers).
• Never charge non-rechargeable batteries.
• Never charge rechargeable batteries not listed in the above table.
• Never charge rechargeable batteries with integrated electronics.
• Never charge rechargeable batteries that are still connected to other devices (e.g. a speed controller).
• Never charge any damaged or bloated rechargeable batteries.

9. Commissioning
a) Connection to a Voltage/Current Supply
Attention!
Always connect the charger to the voltage/current supply rst; only then must a rechargeable battery be
connected to the charger.
The charger offers two different options for operation:
• Operation via the mains voltage (230 V/AC, 50/60 Hz)
• Operation via stabilised direct voltage (11 - 18 V/DC, e.g. via an external vehicle lead battery or a mains adapter)
Never use both operating modes at the same time. This may damage the charger. Loss of guarantee/war-
ranty!
The charger has a maximum total charging output of 200 W. If the charger is to be operated via the direct voltage
input, the power supply strength must be chosen depending on how high the actually used charging output is (depend-
ing on the rechargeable battery type, cell number and the charging current set).
When fully using the maximum total charging output of 200 W, the conversion loss increases power intake
by about 20 - 30%.
If the charger is not to be operated at a 12 V vehicle lead battery, but via a xed voltage mains unit, it must
be able to supply a correspondingly high current.
When using the direct current input, observe the correct polarity when connecting (plus/+ and minus/-).
The charger will switch on automatically after connecting to the voltage/current supply. The two displays light up and
the starting message appears. The charger emits a brief signal.
The charger is then ready for operation.

15
b) Connection of a Rechargeable Battery to the Charger
Please observe the following points before connecting or charging/recharging the battery:
• If you have not done so already, please read chapters 5, 6 and 7 completely and ensure that you have
understood the information there.
• Do you know all of the information you need to know about your battery? Unknown or unlabelled batter-
ies, the necessary values of which you do not know, must not be connected/charged/discharged!
• Have you selected the correct charging/discharging program for the type of battery you are using? Incor-
rect settings will damage the charger and the battery; there is a danger of re and explosion!
• Did you set the correct charging or discharging current?
• Have you selected the correct voltage (e.g. for multiple-cell LiPo batteries)? A two-cell LiPo battery may
be switched in parallel (3.7 V) or series (7.4 V).
• Are all connector cables and plugs undamaged, do the plugs stay rmly in the sockets? Worn plugs and
damaged cables should be replaced.
• Connect only one single rechargeable battery or rechargeable battery pack to each of the two charging
channels of the charger, but never several at once per charging channel. Never connect the charging
channels to each other! The two charging channels are all independent of each other.
• When connecting a rechargeable battery to the charger, always connect the charging cable to the charg-
er rst. Only then must the charging cable be connected to the rechargeable battery. When disconnect-
ing, proceed in reverse order (rst disconnect the rechargeable battery from the charging cable, then the
charging cable from the charger).
Failure to do so presents the danger of a short circuit. This can result in a re or explosion of the re-
chargeable batteries!
• If you wish to charge battery packs that you have manufactured yourself, the cells must be identical in
their construction (same type, same capacity, same manufacturer).
The cells must also be charged to the same level (lithium batteries can be balanced out using the bal-
ancer. This is, however, not possible with other battery packs such as NiMH or NiCd).
• Before connecting a rechargeable battery/battery pack to the charger, disconnect it completely, e.g. from
a ight or speed controller.
Important when charging/discharging a lithium battery pack with balancer connection:
Multi-cell lithium battery packs usually always have a balancer connection. This permits the charger to monitor the
voltage of every single cell separately at all times.
The charger adjusts the voltage of all cells to each other if there are deviations. The balancer prevents that one or
several cells are over-charged or other cells not sufciently fully charged by this. The balancer therefore protects both
from over-charging (which may cause re or explosion) and from deep discharge of a single cell, and thus ensures
best performance of the battery pack in your model.

Procedure when connecting a battery pack to the charger:
1. Connect the charger to the voltage/current supply.
2. Select one of the two charging channels. First connect the charging cable to the two 4 mm round sockets of the
corresponding charging output (#1 or #2). Ensure correct polarity (red cable = plus/+, black cable = minus/-).
The charging cable must not be connected to the rechargeable battery yet! There may be a short-circuit of
the charger plugs; there is a danger of re and explosion!
3. If you want to connect a multiple-cell lithium rechargeable battery to the charger with a balancer cable, connect a
balancer board (enclosed) to the respective socket of the charger.
4. Connect the charging cable to the rechargeable battery now. Ensure correct polarity (red cable = plus/+, black
cable = minus/-).
5. Connect the balancer plug of a multiple-cell rechargeable lithium battery to the corresponding connection of the
balancer board. Do not use any force for plugging in! Ensure correct polarity.
If the balancer plug of the rechargeable battery does not match the shape of the socket on the balancer board,
you need to use a matching connection cable (or another balancer board).
Proceed in the following steps when disconnecting a rechargeable battery:
1. If you have connected a lithium rechargeable battery with a balancer cable to the charger, disconnect it from the
charger/balancer board.
2. Then disconnect the charging cable from the rechargeable battery.
3. Last disconnect the charging cable from the charger.
Always proceed in this order!
The rechargeable battery must always be disconnected from the charging cable (and from the balancer
connection for lithium rechargeable batteries) rst. Only then must the charging cable be disconnected
from the charger.
Any other order poses danger of short circuit by the two round plugs of the charging cable connected to the
rechargeable battery, as well as danger of re and explosion!
4. If no rechargeable battery is connected to the charger anymore, you can disconnect the charger from the voltage/
current supply.

• In a submenu, you can call the different settings with the buttons "INC" and "DEC".
• To modify a value, push the "START/ENTER" button - the display then ashes. Modify the value ashing in the
display using the "INC" and "DEC" buttons. For quick adjustment of a value (e.g. the charging current), keep the
respective button pushed for a longer time.
• Save the (modied) value with the "START/ENTER" button.
• Exit each setting menu using the "BATT TYPE./STOP" button. The charger then returns to the main menu.
Various information is indicated on the display during a charge/discharge process by repeatedly pressing
the button "DEC". If you do not push any button for a few seconds, the charger will return to the normal
display.
If a Lithium rechargeable battery with balancer plug is connected to the charger, you can push the button
"INC" while charging/discharging to switch to the voltage display for the individual cells. Briey push the
"START/ENTER" button so that the charger will return to the normal display.

11. Lithium Batteries (LiPo, LiIon, LiFe, LiHV)
a) General
The rechargeable battery programmes for LiPo, LiIon, LiFe and LiHV rechargeable batteries generally differ only in
the voltages and the permitted charging current, see table in chapter 7.
When charging a lithium battery, there are two different phases. First, the rechargeable battery is charged with a
consistent current. When the rechargeable battery reaches its maximum voltage (at a LiPo rechargeable battery, e.g.,
4.2 V), charging continues at constant voltage (the charging current drops). When the charging current drops below a
certain threshold, charging is ended and the rechargeable battery is fully charged.
If the rechargeable battery has a balancer connection (usually this is the case in almost every lithium bat-
tery with more than one cell), the balancer connection must be connected to the charger as well as the
rechargeable battery's cable for charging/discharging.
There are different types of balancer plug. Therefore, do not apply any force when the plug does not t in
the included balancer board! The matching adapters for the balancer plugs are available as accessories.
There are also rare rechargeable batteries with more than one cell where the cell connections are sepa-
rately routed out and that strictly speaking are not a "multiple-cell battery pack". Therefore, always observe
the information of the rechargeable battery manufacturer on the build and rated voltage.
When using a balancer (integrated in the charger), all cells of a multi-cell battery pack have the same
voltage after the charge process, which prevents the overcharging of individual cells (danger of re and
explosion) or a deep discharge of one of the cells (damage to the rechargeable battery).
The charging current to be set depends on the battery capacity and build (see chapter 7). Always observe
the battery manufacturer's instructions.
Proceed as follows:
The charger must be in the main menu.
Select the rechargeable battery type matching the rechargeable battery used
here with the button "BATT TYPE./STOP" or "DEC" (LiPo, LiIon, LiFe or LiHV),
see gures on the right.
Conrm the selection by pressing the "START/ENTER" button.
Then use the button "INC" or "DEC" to select the different rechargeable bat-
tery programmes:
• "CHARGE": Charge lithium battery without balancer connection
• "BAL-CHG": Charge lithium battery with balancer connection
• "STORAGE": Charging/discharging rechargeable lithium battery at a set
voltage value (e.g. for storage)
• "DCHG": Discharging the rechargeable lithium battery

b) Charging Batteries without Balancer Connection ("CHARGE")
Of course, you can also charge multiple-cell lithium rechargeable batteries with a balancer connection with
the rechargeable battery programme "CHARGE".
However, the individual cell voltages are not reconciled here, so that one or several cells may be over-
charged. There is a risk of re and explosion!
Therefore, always charge multiple-cell lithium rechargeable batteries with balancer connection with
the rechargeable battery programme "BAL-CHG", but never with the rechargeable battery programme
"CHARGE"!
• First, choose the rechargeable battery type with the button "BATT TYPE./STOP" or "DEC" as described in chapter
11. a) (LiPo, LiIon, LiFe or LiHV) and push the button "START/ENTER".
• Select the rechargeable battery programme "CHARGE" with the button
"INC" or "DEC".
The previously selected rechargeable battery type is written in the upper
left. The upper right shows the cell number ("3S" = 3-cell rechargeable bat-
tery), the lower left the rechargeable battery capacity, and the lower right the
currently set charging current.
Use the button "INC" or "DEC" to select a different rechargeable battery programme; use the button "BATT
TYPE./STOP" to return to the main menu.
• If the values need to be changed, push the "START/ENTER" button. The number of cells in the upper right of
the display is ashing. Set the number of the cells with the buttons "INC" and "DEC". Keep the respective button
pressed for quick adjustment.
Conrm the number of the cells by pressing the "START/ENTER" button.
• The rechargeable battery's capacity ashes. Set the rechargeable battery's capacity with the buttons "INC" and
"DEC". Keep the respective button pressed for quick adjustment.
Conrm the rechargeable battery's capacity by pressing the "START/ENTER" button.
• The charging current ashes. Change the charging current using the button "INC" or "DEC". Keep the respective
button pressed for quick adjustment.
The maximum possible charging current depends on the battery type and number of cells. The maximum
charging power is 100 W per channel.
Conrm the charging current with the "START/ENTER" button.
• When no display is ashing anymore, start charging by keeping the "START/
ENTER" button pushed (approx. 3 seconds).
The charger now examines the connected rechargeable battery.
If the settings are wrong, or if the charger detects a problem, an audio signal is emitted and the appropriate
information is shown on the display. You can stop the warning signal by pressing the "BATT TYPE./STOP"
button. You then return to the previous conguration menu.
If no error was recognised, e.g. the display on the right will appear (alternat-
ing).
The "S:" value indicates the cell number that you have set in the menu (in
the example a 3-cell rechargeable battery).
The "R:" value indicates the cell number that the charger has recognised (in
the example also a 3-cell rechargeable battery).
