Recommended separation distances between portable and mobile RF
communications equipment and this camera
This camera is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of this camera can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and this camera 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 metres (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 80 MHz and 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.
