7.1.4 Table 206: Recommended safe distances
between portable and mobile HF communi-
cations equipment and MEDICAL_PLUS
MEDICAL_PLUS has been designed for use in an electromagnetic environ-
ment in which the radiated HF interference is controlled. The operator of the
massage device can help to reduce electromagnetic interference by maintain-
ing a safe distance between the portable and mobile HF communication de-
vices (transmitters) and the device itself as recommended below with regard
to the communication device's maximum output power.
Nominal transmitter power (W) Safe distance with regard to the transmitting frequency (m)
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2,5 GHz
0.01 0.12 0.12 0.23
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
The recommended safe distance (d) in metres (m) can be determined by
using the equation that applies to the transmitters frequency in the case of
transmitters where their nominal power is not listed above, whereby 'P' is the
nominal transmitter power in Watts (W) according to the details supplied by
the manufacturer of the transmitter.
Comment 1: The higher value applies to 80 MHz und 800 MHz.
Comment 2: The propagation of electromagnetic waves is affected by absorp-
tion and reflexes caused by buildings, objects and people.
