Recomme
nded Separation Distances between Portable and
Mobile RF Communications Equipment and the LX-7230
The LX-7230 is intended for use in an environment in which radiated RF
disturbances are controlled. The customer or the user of the LX-7230 can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters)
and the LX-7230 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 80MHz and 800MHz, 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.
