• This product complies with the requirements to
electromagnetic compatibility for medical electric
equipment and for use in residential, offi ce or light
industrial environment but all electric products
imply a potential for electromagnetic or other
interference between the product and other
devices. If such interference is suspected please
disconnect the product from the mains and
consult a qualifi ed technician, your supplier or the
manufacturer.
• No special maintenance procedure is required
but if the product gets dusty or dirty it should be
wiped clean using a dry cloth while the product
is disconnected from the mains. No other
maintenance should be necessary.
• For products having a plastic casing, please avoid
any contact with lotions, oils, grease and solvents
as most types of plastic may be degraded by such
chemicals. Also make sure to position, operate and
store such products away from UV-light and direct
sunlight.
• Position, operate and store this product only under
reasonable foreseeable environmental conditions
with respect to magnetic fi elds, EM-fi elds,
electrostatic discharges, pressure or variations in
pressure, acceleration etc.
• If this product is used with or mounted in a vehicle
it may only be used when the vehicle is not in use.
• When in use, position this product so that the label
can be read – within 40 cm of the operator.

Turn the product off and allow it’s housing to cool
down prior to moving it to another location.
Cautions to observe prior to charging Li-Ion-batteries
• Li-Ion chargers are designed for charging Li-Ion
(LI) batteries only. Make sure you have the correct
battery charger for the chemistry and number of
cells in series. If the number of cells in series in
the battery pack is not known you can calculate it
by dividing the voltage indicated by 3.6VDC for LI
(e.g. a 14.4VDC LI battery contains 4 Li-Ion cells).
Make sure the charge voltage indicated on the
charger corresponds to the number of battery cells
in series multiplied by 4.2VDC (e.g. a 4 cell LI
battery is typically charged using 16.8VDC).
NOTE: The voltages indicated above are typical
and may vary between battery types and battery
makes. If in doubt; consult the specifi cations for
your battery.
• Make sure the specifi cations for your battery allows
for the maximum charge current indicated on the
charger.
• Make sure the specifi cations for your battery allows
for the environmental conditions present during
charging.
• Never attempt to charge batteries that are not
rechargeable.
• We recommend that you connect the charger
to the mains before connection is made to the
battery. This will reduce the sparks that may occur
due to difference in potential between charger
terminals and battery terminals. Note! Make sure
the charger terminals are not short-circuited and
ensure that the polarity is correct.
• Please ensure correct polarity when connecting
to the battery terminals. Reverse polarity conne-
ction may, in some chargers (see the chargers
specifi cations), result in a fuse blowing, requiring
replacement or leaving the charger useless.
• The charge cycle starts when the charger is
connected to the mains.
• If the charger is disconnected from the mains
voltage during a charge cycle the charger will start
a new charge cycle when it is reconnected to the
mains.
• The recommended minimum and maximum
battery capacity for which the specifi c charger
can be used vary from battery to battery. Please
follow the datasheet and recommendations from
the battery manufacturer. In our tables we use
