possible fire or electrical shock.
· When unplugging the AC adaptor from an
electrical outlet, always make sure to pull
on the adaptor itself and not the cord. Pull-
ing excessively on the cord may cause it to
be damaged or break leading to possible
fire or electrical shock.
· Do not touch the AC adaptor with wet
hands when it is plugged in. This may cause
electrical shock.
