Recommended Separation Distances Between Portable and
Mobile RF Communications Equipment and the
SIDNE® Berchtold® ChromoVision Camera Package
The SIDNE Berchtold ChromoVision Camera package is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The user of the SIDNE Berchtold
ChromoVision Camera package can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters)
and the SIDNE Berchtold ChromoVision Camera package as recommended below, according to
the maximum output power of the communications equipment.
Rated maximum
output power (W)
of transmitter
Separation distance (m) according to frequency of
transmitter
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
0.01 0.12 0.12 0.23
0.1 0.37 0.37 0.74
1 1.17 1.17 2.33
10 3.70 3.70 7.37
100 11.70 11.70 23.30
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.
