Recommended Separation Distances between Portable and 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 and
mobile RF communications equipment (transmitters) and the device as recommended
below, according to the maximum output power of the communication equipment.

For transmitters at a maximum output power not listed above, the separation distance
can be estimated using the equation in the corresponding column, where P is the
maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
Note 1: From 80 MHz to 800 MHz, 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.
