Recommended separation distances between
portable and mobile RF communications equipment and the DEVICE .
The DEVICE is intended for use in an electromagnetic environment in which radiated RF
disturbances 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 communications equipment.
Rated maximum Separation distance according to frequency of transmitter

(W)
150 KHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
0.01 0.117 0.117 0.233
0.1 0.369 0.369 0.738

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (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.
NOTE 1 At 80 MHz and 800 MHz, 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.
