3. Warnings and Safety Notes
• Never leave the charge unsupervised when it is connected to
its power supply. If any malfunction is observed immediately
terminate the process and refer to the operation manual.
• Keep away the unit from dust, damp, rain, heat direct
sunshine and vibration. Do not drop it.
• The circuit of the unit is designed to be powered by a 12 V DC
only.
• This unit and the battery to charge or discharge should be set
up on a head-resistant, non-inflammable and non-conductive
surface. Never place them on a car seat, carpet or similar.
Keep all the inflammable volatile materials well away from
operating area.
• Be sure to understand the information of the battery to be
charged or discharged accurately. If the program is set up
incorrectly the battery can severely be damaged.
Especially Lithium batteries can cause fire or an explosion by
over-charging.

• To avoid short-circuits between the charge lead, always
connect the charge cable to the unit first and only then to the
battery to be charged or discharged. Reverse the sequence
when disconnecting.
• Do not connect more than one battery pack to the charge lead
at any one time.
• Do not attempt to charge or discharge the following types of
batteries:
- Battery pack, which consists of different types of cell
(including different manufacturers).
- Battery, which is already fully charged or just slightly
discharged.
- Non-rechargeable batteries (Explosion hazard).
- Batteries that require different charge technique from
NiCd, NiMH, Lilo, LiPo, LiFe or Pb.
- Faulty or damaged batteries.
- Battery fitted with an integral charge circuit or a protection
circuit.
- Batteries installed in a device, or which are electrically
linked to other components.
- Batteries that are not expressly stated by the manufacturer
to be suitable for the currents the charger delivers during
the charge process.
• Please bear in mind of checking the following points before
charge operation.
- Did you select the appropriate program, which is suitable
for the type of battery?
- Did you set up the adequate current for charging or
discharging?
- Lithium battery packs can be composed with parallel and
series circuits mixed. You have to check the composition of
the battery pack carefully before charging.
- Are all connections firm and safe, or is there an
intermittent contact at any point in the circuit?
