Minimal distances recommended for portable and mobile RF communication equipment and
Therapy EC.
Therapy EC is designated to be used in electromagnetic environment in which radiated RF disturbances are
controlled. Therapy EC’ customer or user may help avoiding electromagnetic interference keeping a minimal
distance between portable or mobile RF communication equipment (transmitters) and Therapy EC, as recom-
mended below, according to the maximum output power of communication equipment.

For transmitters with maximum nominal power not listed above, the recommended distance (in meters [m])
can be determined by equation applicable to transmitter frequency.
Note 1:
In 80 MHz to 800 MHz, the distance for highest frequency range is applied.
Note 2:
These standards can’t be applied at all situations. Electromagnetic propagation is affected by ab-
sorption and reflection of structures, objects and people.
