Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,

should be less than the
compliance level in each frequency

.
Interference may occur in the vicinity of 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 structure, objects, and
people.
a
Field strengths from fixed transmitters, such as base stations for radios (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 NanoVi
®
Wellness is used exceeds the applicable
RF compliance level above, the NanoVi
®
Wellness should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the NanoVi
®
Wellness.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances
Recommended separation distances between portable and mobile RF communications equipment and the
NanoVi
®
Wellness
The NanoVi
®
Wellness is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user if the
NanoVi
®
Wellness can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the NanoVi
®
Wellness 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) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 The guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and
people.
