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 10Vrms or 10V/m.
Interference may occur in the vicinity of
equipment containing a transmitter.
Conducted RFI and Radiated RFI testing was performed on the EUT. Monitoring the output for drops in voltage; none
were detected.

Guidance and Manufacturer’s Declaration - Emissions
The Image Capture System is intended for use in the electromagnetic environment in which radiated
disturbances are controlled. The customer or user of the Image Capture System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
Communications Equipment and the Image Capture System as recommended below, according to the
maximum output power of the communications equipment.
