Guidance and manufacturer’s declaration – electromagnetic immunity
... compliance level in each frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
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 The ISM (industrial, scientific and medical) bands between 150kHz 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; 40,66 MHz to 40,70 MHz.
b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range
80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment
could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor
of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for
transmitters in these frequency ranges.
c 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 where the
SAM 450P is used exceeds the applicable RF compliance level (see above), the SAM 450P should be
observed to verify that it is operating normally. If abnormal operation is observed, additional measures may
be necessary, such as re-orienting or relocating the SAM 450P.
