MAGSTIM BiStim2 Operating Manual page 31

The Magstim Bistim² is intended for use in the electromagnetic environment specified below. The customer or the user of the equipment
should assure that it is used in such an environment.
Immunity Test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to
2,5 GHz
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 Bistim² is used exceeds the applicable RF compliance level above, the Magstim Bistim² 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 Bistim².

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V
