Portable and mobile RF communications
equipment should be used no closer to any part
of this X-ray System, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
where ’P’ is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and ’d’ is the
recommended separation distance in meters

NOTE 1 -- At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 -- These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
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 this X-ray System is used exceeds the applicable RF compliance level above, this X-ray System should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating this X-ray System.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
