Technical Specifi cations
UT is the A.C. mains voltage prior to application of the test level.
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
refl ection from structures, objects, and people.
A Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be
considered. If the measured fi eld strength in the location in which the ProCair Plus control unit is used exceeds the
applicable RF compliance level above, the ProCair Plus control unit should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the ProCair
Plus control unit.
B Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.

Mains power quality should be that of a
typical home healthcare and professional
healthcare environment. If the user of the
ProCair Plus control unit requires continued
operation during power main interruptions, it
is recommended that the ProCair Plus control
unit be powered from an uninterruptible power
supply or a battery.

Where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
