Recommended Separation Distances Between Portable and Mobile
RF Communications Equipment and The Vest® Airway Clearance
System, Model 105
The Vest® Airway Clearance System, Model 105 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or user of
The Vest® Airway Clearance System, Model 105 can help prevent electromagnetic interfer-
ence by maintaining a the minimum distance between portable and mobile RF communi-
cations equipment (transmitters) and The Vest® Airway Clearance System, Model 105 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 meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where
P
is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufacturer.
NOTES:
•
At 80 MHz to 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.
