Recommended separation distances between portable and mobile RF communications equipment and the product
The product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the product can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the product 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.
NOTE 1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
