●Recommended Separation Distances between Portable and

Mobile RF Communications Equipment and the LX-7120(G)

The LX-7120(G) is intended for use in an environment in which radiated RF

disturbances are controlled. The customer or the user of the LX-7120(G) can

help prevent electromagnetic interference by maintaining a minimum distance

between portable and mobile RF communications equipment (transmitters)

and the LX-7120(G) as recommended below, according to the maximum

output power of the communications equipment.

100 12 12 23

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.
