Electromagnetic Compatibility
Recommended separation distances between portable
and mobile RF communications equipment and the
SmartVest
SQL Airway Clearance System.
The
SmartVest
Airway Clearance System is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the System as recommended
below, according to the maximum output power of the communications
equipment.

100 11,70 11,70 23,30
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 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.
