▐ Recommended Separation Distances between This Product
and RF Communications Equipment
This product is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of this product can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and this product. These distances are
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d
in meters (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’s manufacturer.
NOTE 1) At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2) These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
