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.
