Recommended Separation Distance between Portable/Mobile RF
Communications Equipment and the Device
The device is suitable for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of the device can help prevent
electromagnetic interference by maintaining a minimum distance between portable/mobile RF
communications equipment (transmitters) and the 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 determined 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.
Note 1: At 80 MHz to 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines can not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
