Liability Exclusion - GRAUPNER SJ Ultra MFD 150 Instructions D'utilisation

Please bear in mind that new batteries do not reach their full capacity until they have undergone
several charge / discharge cycles. You should also be aware that the charger may terminate
the charge process prematurely when connected to new packs, and batteries which have
been deepdischarged.
A LiXX pack will normally be warm at the end of a rapid-charge process, but if you notice that
one cell of the pack is much hotter than the others, this may well indicate a fault in that cell.
Such packs could fail completely without warning, and should not be used again. Dispose of
the battery safely, preferably taking it to a toxic waste disposal centre.
Ensure that all connectors and terminal clamps make good, sound contact. For example, if there
is a brief interruption due to an intermittent contact, the result is inevitably a malfunction such
as a restart of the charge process, which would result in the pack being massively overcharged.
A common cause of malfunctions is the use of unsuitable charge leads. Since the charger is
incapable of detecting the difference between a pack's internal resistance, cable resistance
and connector transfer resistance, the fi rst requirement if the charger is to work perfectly is that
the charge lead should be of adequate conductor cross-section and should be not be more
than 30 cm long Goodquality connectors (gold-contact types) must be fi tted to both ends).
To avoid possible damage to the internal transmitter components due to overheating and heat
build-up, we recommend that the battery should be removed from the transmitter's battery
compartment prior to charging.
When you set a particular current for charging, the charger only supplies that current if the value
does not exceed the unit's technical capacity! If you set a charge current which the charger
cannot deliver because it falls outside its technical limits, the unit automatically reduces the
current to the maximum possible value. In this case the screen displays the charge current
which is actually flowing.
