Electronic elements including capacitance and inductance on the
device can be affected by external interferences, such as conducted
emission by capacitance coupling, inductance coupling, and
impedance coupling. To decrease the interferences, please make
sure to take the following measures:
Use the power supply that can effectively filter interference from
the power grid.
Keep the devices far from high-frequency, strong-current devices,
such as radio transmitting station.
Use electromagnetic shielding when necessary.
