Guidance
Complies Floors should be
wood, concrete, or
ceramic tile. If
floors are covered
with synthetic
material, the
relative humidity
should be at least
30%.
Complies Main power should
be that of a typical
commercial or
hospital
environment.
Complies Power frequency
magnetic fields
should be at levels
characteristic of a
typical location in a
typical commercial
or hospital
environment.
3 Vrms Portable and mobile
RF communications
equipment should
be used no closer to
any part of the
3 Vrms NPB-40, including
the cables, than the
recommended
separation distance
calculated from 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 and d is the
recommended separation distance in
meters (m).
