WARNING
• If you use any medical electric de-
vices, such as an implantable cardiac
pacemaker or an implantable cardio-
vascular defibrillator, check with the
electric medical device manufac-
turer concerning the effects that
charging may have on implanted de-
vices before starting the charge op-
eration. Charging may affect the
operation.
• Make sure there is no water or for-
eign materials in the charge port,
charge connector, or electrical plug,
and that they are not damaged or
affected by rust or corrosion. If any of
these conditions are noticeable, do
not charge the Li-ion battery. This
may result in a short circuit or electric
shock and could cause a fire which
may result in serious personal injury
or death.
