Portable and mobile RF communications equipment should be
used no closer to any part of the device, including cables, than
the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance:
d=1.2√
P
150 kHz to 80 MHz
d=1.2√
P
80 MHz to 800 MHz
d=2.3√
P
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

The Concentrator is intended for use in the electromagnetic environment specified below. The user
of the Concentrator should make sure it is used in such an environment.
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

Mains power quality should be that of a typical commercial
or hospital environment. If the user of the [ME EQUIPMENT or
ME SYSTEM] requires continued operation during power mains
interruptions, it is recommended that the
[ME EQUIPMENT or ME SYSTEM] be powered from
an uninterrupted power supply or a battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical hospital or home
environment.
