charger. Do not charge any non-re-
chargeable batteries. Otherwise
there is a danger of fire and explo-
sion.
Keep the battery charger away from rain or
moisture. Penetration of water in the battery
charger increases the risk of an electric shock.
 Keep the battery charger clean. Contamination can lead
to danger of an electric shock.
 Before each use, check the battery charger, cable and
plug. If damage is detected, do not use the battery
charger. Never open the battery charger yourself.
Have repairs performed only by a qualified technician
and only using original spare parts. Damaged battery
chargers, cables and plugs increase the risk of an electric
shock.
 Do not operate the battery charger on easily inflamma-
ble surfaces (e. g., paper, textiles, etc.) or surround-
ings. The heating of the battery charger during the charg-
ing process can pose a fire hazard.
 In case of damage and improper use of the battery, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
 Do not cover the ventilation slots of the battery charg-
er. Otherwise, the battery charger can overheat and no
longer operate properly.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.

Starting Operation
 Observe the mains voltage! The voltage of the power
supply must correspond with the data given on the name-
plate of the battery charger. Battery chargers marked with
230 V can also be operated with 220 V.
Charging Procedure
The charging procedure starts as soon as the mains plug of
the battery charger is plugged into the socket outlet and the
battery 1 is inserted into the charging compartment 3.
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery is
charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Note: The charging procedure is only possible when the bat-
tery temperature is within the allowable charging tempera-
ture range, see "Technical Data" section.
Meaning of the Indication Elements
Flashing Battery Charge Indicator 2
The charging procedure is signalled by a flash-
ing battery charge indicator 2.
Continuous Lighting of the Battery Charge Indicator 2
Continuous lighting of the battery charge in-
dicator 2 indicates that the battery is fully
charged or that the temperature of the battery
is not within the allowable charging tempera-
ture range, and cannot be charged for this reason. The battery
is charged as soon as the allowable charging temperature
range is reached.
