Recommended separation distances between portable and mobile RF communication equipment and
“Xmind®dc” medical device
These devices are intended to be used in environments where radiated RF interference is controlled. The
customer or “Xmind®dc” operator can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communication equipment (transmitters) and “Xmind®dc” , as
indicated below, according to the maximum output power of the communication equipment.
Rated maximum output
power of the transmitter
[W]
Separation distance according to transmitter frequency
[m]
150 kHz - 80 MHz
d = 1,2 √P
80 MHz - 800 MHz
d = 1,2 √P
800 MHz - 2.5 GHz
d = 2,3 √P
0.01 0.12 0.12 0.24
0.1 0.38 0.38 0.73
1 1,2 1.2 2.3
10 3,8 3.8 7.3
100 12 12 23
In the event of transmitters whose maximum nominal output power coecient does not fall within the indicated
parameters, the recommended separation distance in metres (m) can be determined by means of the equation
corresponding to the frequency of the transmitter, where P is the maximum output power coecient of the
transmitter in watts (W) according to the information provided by the manufacturer.
Note 1: At 80 MHz and 800 MHz apply the separation distance corresponding to the highest frequency range.
Note 2: These guidelines may not apply in every situation. Electromagnetic propagation is affected by absorption
and reection from structures, objects and people.
