NOTICE! RF communications equipment can effect
medical electrical equipment.
* Field strengths from fixed transmitters, such as base stations for cellular telephones and land mobile
radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be estimated accurately. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should
be performed. If the measured field strength exceeds the RF compliance level above, observe the device to
verify normal operation in each use location. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the device.
Guidance for actions taken can be found from AAMI TIR 18:2010, Guidance on electromagnetic
compatibility of medical devices in healthcare facilities.
NOTICE! Precautions to take if the use location is near (e.g. less than 1,5 km from) AM, FM or TV broadcast
antennas.
** Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m. The Recommended
Separation Distances are listed in the next table .
NOTICE! These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
