It is not advisable to use mobile or portable RF communication
equipment at shorter distances from any part of
Oxymag
, including
cables, than the recommended separation distance, calculated by
the equation applicable to the frequency of the transmitter.

Where P is the declared maximum level of transmitter output power
in watts (W) according to the transmitter manufacturer, and d is the
recommended separation distance in meters (m) .b
The field strength from RF transmitters, determined by an
electromagnetic field survey, c should be less than the level of
compliance for each frequency range.d
Interference may occur in the vicinity of the
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 industrial, scientific and medical (ISM) 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. 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 MHz. , 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 Compliance levels in the ISM frequency bands between 0.15 MHz and 80 MHz and in the 80 MHz to 2.7 GHz frequency range are set to reduce the possibility of
mobile / portable RF communication equipment causing interference if inadvertently brought into patient areas. Therefore, an additional factor of 10/3 has been
incorporated into the formulas used in calculating the recommended separation distance for transmitters in these frequency ranges.
c Field strength from fixed transmitters such as telephone base stations (mobile or cordless) and mobile ground radios, amateur radio, AM and FM radio broadcasts
and TV broadcasts cannot be predicted theoretically with precision. . To assess the electromagnetic environment generated by fixed RF transmitters, an electromagnetic
field survey should be considered. If the measured field strength at the location where Oxymag will be used exceeds the applicable RF CONFORMITY LEVEL set
