NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the model Rooter
®
X3000 is used exceeds the applicable RF compliance level above,
the model Rooter
®
X3000 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the model Rooter
®
X3000.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
