Recommended distance between portable and mobile communications equipment and
the product (Table 206)
The product is intended for use in an electromagnetic environment with controlled HF
interferences. The customer or the user of the product can avoid electromagnetic interference
by respecting and observing the minimum distance between portable and mobile HF
telecommunication devices (transmitters) and the product depending on the rated output of the
communication device as given below.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance
d
in meters (m) can be determined using the equation applicable to the
frequency of the transmitter, where
P
is the maximum output power rating of the transmitter in
watts (W) according to the specifications given by the transmitter manufacturer.
NOTE 1:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2:
These guidelines could not apply to all situations. Electromagnetic propagation
is affected by absorption and reflection from structures,
objects and people.
