8.3.4 Recommended separation distances between portable and mobile RF
communications equipment and the ventilator
The ventilator is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the ventilator can help pre-
vent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the ventilator as recom-
mended 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
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
