environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the model MyOxy, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1.2×P½
d=1.2×P½ 80 MHz to 800 MHz
d=2.3×P½ 800 MHz to 2.5 GHz
where P is the maximum output power rating
of the transmitter In watts (W) according to
the transmitter manufacturer and d Is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,a
should be less than the compliance level in each
frequency range.b
Interference may occur In the vicinity of
equipment marked with the following symbol:
a 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 model MyOxy is used exceeds the applicable RF compliance level above, the
model MyOxy should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the model MyOxy.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the model MyOxy - The model MyOxy is intended for use in electromagnetic
environment in which radiated RF disturbances is controlled. The customer or the user of the
model MyOxy can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and
the model MyOxy as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) accordable
to the transmitter manufacturer.
NOTE I At 80 MHz and 800 MHz. the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
