Recommended separation distances between portable and mobile RF
communications equipment and the Fish Pediatric Compressor Nebulizer 18090-FS
and 18091-FS.
The Fish Pediatric Compressor Nebulizer is intended for use in an electromagnetic environ-
ment in which radiated RF disturbances are controlled. The customer or the user of the Fish
Pediatric Compressor Nebulizer can help prevent electromagnetic interference by maintain-
ing a minimum distance between portable and mobile RF communications equipment (trans-
mitters) and the Fish Pediatric Compressor Nebulizer 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 din metres (m) can be estimated using the equation applicable to the frequency of the
transmitter, where Pis 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.
