Field strengths from
fixed RF transmitters,
as determined by an
electromagnetic site
survey, a) should
be less than the
compliance level in each
frequency range.
Interference may
occur in the vicinity of
equipment marked with
the following symbol:
Table C3 : Guidance and manufacturer’s declaration – Electromagnetic immunity - for all
EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
NOTE
At 80 MHz and 800 MHz, the higher frequency range applies.
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 Hatch X-Ray is used
exceeds the applicable RF compliance level above, the Hatch X-Ray
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or
relocating the Hatch X-Ray
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
