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 0,15 MHz 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. The amateur radio
bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz
to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz,
24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range
80 MHz to 2,7 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 in which
the WatchBP Home T(BP3MX1-3T) is used exceeds the applicable RF compliance level above, the
WatchBP Home T(BP3MX1-3T) should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the WatchBP Home T
(BP3MX1-3T).
d
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
