Separation distances recommended between portable and mobile RF communications systems and this
insufflator
This insufflator is designed to be used within an electromagnetic environment in which radiated RF interference is
controlled. The user of this insufflator can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communication systems (transmitters) and this insufflator, such as recommended
below, as a function of the maximum output power of the communications system.

Note 1 At 80 MHz and 800 MHz, the higher frequency band applies.
Note 2 These recommendations may not apply in all situations. The propagation of electromagnetic waves is modified
by absorption and reflection due to structures, objects and people.
For transmitters of which the maximum output power is not listed above, the recommended separation distance d in
meters (m) can be established by using the equation applicable for the transmitter frequency, in which is the
transmitter’s maximum output power in Watts (W) assigned by the transmitter’s manufacturer.
Note 1 At 80 MHz and 800 MHz, the separation distance stated for the higher frequency range should be applied.
Note 2 These recommendations may not apply in all situations. The propagation of electromagnetic waves is modified
by absorption and reflection due to structures, objects and people.
