Portable and mobile communications
equipment should be separated from the
TMX428 Series by no less than the
distances calculated/listed below:
D=(3.5/V1)(Sqrt P)
150kHz to 80MHz
D=(3.5/E1)(Sqrt P)
80 to 800 MHz
D=(7/E1)(Sqrt P)
800 MHz to 2.5 GHz
Where P is the max power in watts and D
is the recommended separation distance
in meters.
Field strengths from fixed transmitters,
as determined by an electromagnetic site
survey, should be less than the
compliance levels (V1 and E1).
Interference may occur in the vicinity of
equipment containing a transmitter.
Table 6:
Recommended Separation Distances between portable and mobile RF
Communications equipment and the TMX428 Series ME Equipment and ME Systems that
is NOT Life-supporting
The TMX428 Series is intended for use in the electromagnetic environment in which radiated disturbances
are controlled. The customer or user of the TMX428 Series can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF Communications Equipment and the
TMX428 Series as recommended below, according to the maximum output power of the communications
equipment.
