a - ISM bands (industrial, medical and scientific) between 150kHz and 80MHz are 6,765MHz to 6.795MHz;
13.553Mhz to 13.567MHz; 26.957MHz to 27.283MHz; and 40.66MHz to 40.70MHz.
The amateur radio bands between 150 KHz and 80 MHz are: 1.8 to 2.0 MHz; 3.5 to 4.0 MHz; 5.3 to 5.4 MHz; 7.0 to
7.3 MHz; 10.10 to 10.15 MHz; 14.0 to 14.2 MHz; 18.07 to 18.17 MHz; 21 to 21.4 MHz; 24.89 to 24.99 MHz; 28.0 to
29.7 MHz; and 50.0 to 54.0 MHz.
b - The compliance levels in the ISM frequency bands between 150kHz and 80MHz and in the frequency range
between 80MHz and 2.5GHz are intended to reduce the likelihood of mobile and portable communications
equipment causing interference if inadvertently brought into the patient areas. Therefore, an additional factor of 10/3
is used in calculating the advisable separation distance for transmitters in these frequency ranges.
c - Field strengths established by fixed transmitters, such as base stations for radio, telephones (cell phone/
wireless) mobile land radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with any accuracy. In order to evaluate the electromagnetic environment due to fixed RF transmitters,
it is advisable to consider an electromagnetic site survey. If the measured field strength in the site where the Apolus
is used exceeds the level of RF compliance used above, the Apolus should be observed to check if operation
is normal. If abnormal performance is observed, additional procedures may be required, such as reorienting or
repositioning the Apolus.
d - Over the frequency range 150kHz to 80MHz, the field intensity should be less than [V1]V/m
