Table 7. Recommended Separation Distance Between Portable and Mobile RF
Communications Equipment and the USBCam2
PLEASE NOTE: The USBCam2 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or user of the USBCam2 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the USBCam2 as recommended below, according to
the maximum output power of the communications equipment.

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 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.
