Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should be
at least 30%. Try to use the
device in the environment
specified. If the condition
of the environment cannot
be determined, other
preventive measures must
be taken, such as using an
antistatic device,
discharging static electricity
from the body or wearing
antistatic clothing.
