Solid-state devices can be susceptible to radio
frequency (RF) interference depending on the
power and the frequency of the transmitting
source. If RF transmitting equipment is to be
used in the vicinity of the solid-state devices,
thorough testing should be performed to
assure that transmitter operation is restricted
to a safe operating distance from the sensor
equipment and its wiring.
