Recommended separation distances between portable and
mobile RF communications equipment and this model
This model is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of this
model can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and this model as recommended below, according
to the maximum output power of the communications equipment.
• At 80 MHz and 800 MHz, the separation distance for the
higher frequency range applies.
• These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

Others: For transmitters rated at a maximum output power not listed above, the recommended
separation distance ‘d’ in metres (m) can be estimated 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 transmitter manufacturer.
