Portable and mobile RF
communication equipment should be
used no closer to any part of the
USBCam system, including its
cables, than the recommended
separation distance calculated from
the equation applicable to the
frequency of the transmitter.

Interference may occur in the vicinity
of equipment marked with the
following symbol.
NOTE 1: At 80 MHz and 800 MHz, 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
