Recommended Separation Distances Between Portable and Mobile
RF Communications Equipment and the Model 205
The Vest
®
Airway Clearance System, Model 205 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or user of the
Model 205 can help prevent electromagnetic interference if they maintain the minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Model 205. The recommended distances, in accordance, are shown below:
Rated Maximum
Output Power of the
Transmitter

For transmitters rated at a maximum output power not listed above, the recommended
separation distance
d
in metres (m) can be estimated with the use of 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 to 800 MHz, the separation distance for the higher frequency range
applies.
NOTE:
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
