CardioMessenger II-S
Appendix
33
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 CardioMessenger is used exceeds the applicable RF compliance level above, the
CardioMessenger should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the CardioMessenger.
b) Above the frequency range of 150KHz to 80MHz, ensure that field strengths are less than 3V/m.
