Table 10: Recommended Separation Distances
This table details the recommended separation distances between portable and mobile RF communications
equipment and this device.
This device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. Users of this device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communication equipment (transmitters) and the device as
recommended below, according to 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 manufacturer.
NOTES:
• 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.
