warning:
Before each use, make sure that the
voltage regulator is set to the correct
voltage position according to the

the voltage regulator should point to
the 240 V mark when the product is

Adjust the voltage by turning the
voltage regulator clockwise from
240V to 110V or counterclockwise
from 110V to 240V.
