a The ISM frequency bands (for industrial, scientific and medical applications)
between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to
13.567 MHz; 26.957 MHZ to 27.283 MHz and 40.66 MHz to 40.70 MHz.
b The conformance levels in the ISM frequency bands between 150 kHz and 80
MHz and the frequency range of 80 MHz and 2.5 GHz are intended to reduce
the probability that mobile and portable communications equipment will pro-
duce disturbances when they are unintentionally brought near the patient. For
this reason, the additional factor of 10/3 is applied in the calculation of the re-
commended safe clearances in these ranges of frequencies.
The field strength of stationary transmitters such as base stations of mobile
c
telephones and land mobile radio devices, amateur radio stations, AM and FM,
radio and television broadcasters cannot be theoretically predetermined. A site
study should be considered to determine the electromagnetic environment in
terms of stationary transmitters. If the measured field strength at the site, at
which the elements e-motion is used, exceeds the compliance levels shown
above, the elements e-motion should be monitored to demonstrate proper
function. If any uncommon performance characteristics are observed, additional
measures may be required, such as, e.g., changing the orientation or using a
different location for the elements e-motion
d In the frequency range of 150 kHz to 80 MHz, the field strength should be less
than 3V V/m.

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
