Portable and mobile RF
communication equipment should be
used no closer to any part of the
USBCam2, including its cables, than
the recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance:
d= 1.2 √ P
d= 1.2 √ P for 80 MHz to 800Mhz
d= 2.3 √ P for 800 MHz to 2.5Ghz
Where P is the maximum output
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation in meters
(m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
be less than the compliance level in
each frequency range.
Interference may occur in the vicinity
of equipment marked with the
