If image distortion
occurs, the product
must be placed
farther a way from the
source of the power
frequency magnetic
field or a magnetic
shielding protection
must be installed.
The power frequency

be measured to
ensure that the
installation position is
sufficiently low when it
is expected to be used.

This distance should
be calculated based
on the formula
corresponding to the
transmitter frequency.
