guidance
Floors should be wood, concrete or ceramic tile.
If floors are covered with synthetic material, the
relative humidity should be at least 30 %.
Mains power quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the [Equipment or System] requires continu-
ed operation during power mains interruptions,
it is re- commended that the [Equipment or
System] be powered from an uninterruptible
power supply or battery.
Power frequency magnetic fields should be
at levels characteristic of a typical location in a
typical commercial or hospital environment
Portable and mobile RF communications
equip- ment should be used no closer to any
part of Red- sense, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2,5 GHz
Where P is the maximum output power rating
of the transmitter in watts (W) according to
the trans- mitter manufacturer and d is the re-
commended 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.
