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.
c
The field strength of stationary transmitters such as base stations of mobile
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.

- Guidelines
Handheld and mobile wireless
devices should not be used at a
shorter distance from the ele-
ments e-motion including cords
than the recommended safe
clearance calculated using the
appropriate equation for the
emission frequency.
Recommended safe distance:
d=1.17
P
d=0.35 P for 80 MHz to 800
MHz
d=0.70 for 800 MHz to 2.5
P
GHz
where P is the maximal nominal
power of the transmitter in watts
(W) as specified by the transmit-
ter manufacturer and d is the re-
commended safe clearance in
metres (m).
b
The field strength of stationary
wireless radio transmitters as
c
measured locally should be
lower than the conformance level
at all frequencies.
d
Interference is possible in the vi-
cinity of devices bearing the fol-
lowing icon.
