Recommended separation distances between portable and mobile RF communication
equipment and the «CCD mono video camera» reference equipment
The equipment «mono ccd camera» is designed to be used in an electromagnetic environment in
which the radiated RF The "CCD mono video camera" reference equipment is intended for use in an
electromagnetic environment where radiated RF disturbances are controlled. The user of the "CCD mono
video camera" equipment can help prevent electromagnetic interference by maintaining a minimal
distance between the mobile and portable RF communication equipment (transmitters) and the "CCD
mono video camera" equipment, as recommended below, depending on the maximum output power of
the communication equipment.

For transmitters with a maximum output power rating that is not listed above, the recommended separation
distance d in metres (m) can be determined by using the equation applicable to the transmitter's frequency,
where P is the maximum output power of the transmitter in Watts (W) assigned by the transmitter's
manufacturer.
Note 1:
At 80 MHz and 800 MHz, the separation distance provided in the higher frequency band applies.
Note 2:
These recommendations may not apply in all situations. The propagation of electromagnetic waves is
aff ected by absorption and refl ection due to structures, objects and people.
