The R-Evo Smart intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the R-Evo Smart can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitter) and the R-Evo Smart as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters with maximum output power not listed in the table above, the recommended
separation distance d in meters (m) can be estimated with the equation applicable to the
transmitter frequency, where P is the maximum output power of the transmitter in watts (W)
in accordance with what is indicated by the transmitter manufacturer.
Note:
(1) at 80MHz and at 800MHz, the separation distance for the higher frequency range
applies.
(2) These guidelines should not be applied in all situations. Electromagnetic propagation
is influenced by absorption and reflection of structures, objects and people.
The field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcasts and television broadcasts can not be predicted
theoretically with precision. To access an electromagnetic environment
generated by fixed RF transmitters, an investigation of the electromagnetic
site must be considered. If the measured field strength in the place where the
R-Evo Smart is used exceeds the applied RF compliance level indicated above,
the R-Evo Smart must be observed to verify normal operation. If abnormal
performance is observed, additional measures will need to be taken, such as
re-orienting or relocating the unit.
Other than the frequency range 150 kHz to 80 MHz, field strength should be
less than 3 V/m.
