VOLTCRAFT Charge Manager 420 Bedienungsanleitung Seite 33

Operation
• This charger may be used to charge up to four rechargeable NiCd or NiMH
round cell batteries of the sizes AA/mignon and AAA/micro simultaneously.
Never insert any other rechargeable batteries (e.g. lithium or nickel-zinc
batteries, etc.) or even non-rechargeable batteries into the charger. There is
great danger of fire or explosion!
• Ensure that there is sufficient ventilation during operation. Never cover up
the charger or the mains adapter. Leave enough distance (at least 20 cm)
between the charger and other objects. Overheating causes a danger of fire!
• The charger may only be connected to a stabilised direct current voltage of
12 V/DC as voltage/current supply (e.g. via the included mains adapter).
• Do not operate the product unattended. Despite a considerable number of
protective circuits, it is impossible to exclude the possibility of malfunctions
or problems during the charging process.
• Do not wear any metal or conductive materials, such as jewellery (necklaces,
bracelets, rings, etc.) while you are working with the charger or batteries.
• Never place metal lines and contacts between the rechargeable battery and
the charging slot!
• Only operate the product in moderate climate, never in tropical climate. For
more information on acceptable 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! The mains adapter poses a danger of potentially fatal electric
shock!
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
fields, transmitter aerials or HF generators. This can affect the control
electronics.
