TABLE 4
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
The system is intended for use in an electromagnetic environment in which radiated
RF
disturbance are controlled. The customer or the user of system can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communication equipment (transmitters) and system as

For transmitters at a maximum output power not listed above, the recommended
separation distanced 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.
If system image distortion occurs, it may be necessary to position system further
from sources of conducted RF noise or to install external power source filter to
minimize RF noise to an acceptable level.
Note 1At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
Note 2These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
