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. The customer or the user of this device can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communication equipment
(transmitters) and this device as 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 manufacturer.
