Table 4:
Recommended separation distances between portable and mobile RF communications equipment and the []
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 recommen-
ded 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 me-
ters (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) accordable 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.
