Portable and mobile RF communication devices
–
cables included - must not be used at a distance nearer
than what is recommended. This distance is calculated
by applying the formula corresponding to the transmitter
frequency.

Where is the maximum output power from the
transmitter, in Watts (W), assigned by the manufacturer
of the transmitter and (d) is the recommended
separation distance in metres (m).
The field strengths emitted by fixed RF transmitters
–
which must be established by in situ electromagnetic
measurements
– must be lower than the compliance
strength in each frequency band.
interference may be caused by devices on which the
following symbol is displayed
:
Note 1: at 80 Mhz and 800 Mhz, it is advisable to use the highest frequency band.
Note 2: these recommendation may not be applicable in all situations. The propagation of
electromagnetic waves is modified by absorption and reflection due to structures, objects and people.
