Note 1:
At 80MHz 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 150 kHz and 80 kHz 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 compliance level in the ISM (Industrial, Scientific and medical) 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 the area
around the patient. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency
ranges. Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency
range. 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 CellAED
®
is used exceeds the applicable
RF compliance level above, the CellAED
®
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the CellAED®. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
