Portable and mobile RF communication equipment
can’t be used close to any part of Therapy EC, including
cables, recommending a safe distance calculated from
equation applicable to transmitter frequency.
Recommended distance:
D = 10.10 m
D = 10.10 m
(80 MHz to 800 MHz)
D = 20.20 m
800 MHz to 2.5 GHz
Where P is maximum nominal transmitter output power
in watts (W), according to the transmitter manufacturer
and D is the distance recommended in meters (m).
It’s recommended the intensity of the field established
by RF transmitter, as determined by an electromagnetic
inspection on site
a
, be lower than compliance level of
each frequency range
b
.
It may clash the equipment marked with the symbol:
Note 1:
In 80 MHz and 800 MHz, the highest frequency range is applied.
Note 2:
These standards can’t be applied at all situations. Electromagnetic propagation is affected by absorption and
reflection of structures, objects and people.
a
Field intensities established by fixed transmitters, such as base radio stations, telephone (mobile/wireless) and terrestrial
trunked radio, amateur radios, AM and FM radio transmission and TV transmitters can’t be predicted theoretically and
precisely. To evaluate electromagnetic environment due to fixed RF transmitters, an electromagnetic inspection on site
is recommended. If measurement of field intensity on site where Therapy EC is used surpasses the compliance level used
above, Therapy EC should be inspected to check whether operation is normal. If an abnormal performance is checked,
additional procedures can be required, such as Therapy EC reorientation or replacement.
b
If the frequency range is higher than from 150 kHz up to 80 MHz, the field intensity should be lower than 3 V/m.
