The Compressor Nebuliser is intended for use in the electromagnetic environment specified
below. The customer or the user of Compressor Nebuliser should assure that it is used
in such an environment.
NOTE 1 At 80 MHz and 800 MHz, 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.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the
Compressor Nebuliser
is used exceeds the applicable RF compliance level above, the
Compressor Nebuliser
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the
Compressor Nebuliser.

Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3V/m.
