Portable and mobile RF communications
equipment should be used no closer to any part of
the Magstim Rapid

System, including cables, than

Field Strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
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 filed strength in the location in which the Magstim Rapid
2
System is used
exceeds the applicable RF compliance level above, the Magstim Rapid
2
System should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the Magstim Rapid
2
System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V
