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

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.

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.

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).

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
