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 device is used
exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Mains power quality should be that of atypical

Mains power quality should be that of a typical
commercial or hospital environment. If the user
of this device requires continued operation
during power mains interruptions, it is recom-
mended that the device be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
Portable and mobile RF communications
equipment should be used no closer to any
part of this device, including cables, than there
commended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d=2.0√P 150kHz to 80MHz
d=2.0√P 80MHz to 800MHz
d=4.0√P 800 MHz to 2.7GHz
Where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in meters (m).b
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
, should be less than the compliance level in
each frequency ranged.
