TABLE 4: RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE
AND MOBILE RF COMMUNICATIONS EQUIPMENT AND LX2
Recommended separation distances between portable and mobile RF
communications equipment and the LX2 device
The LX2 device device is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the LX2 device can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the LX2 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 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.
