Medical equipment needs special precautions regarding EMC and needs to
be installed and put into service according to the EMC information provided in
this section.

of the VisionAire requires continued operation
during power mains interruptions, it is
recommended that the VisionAire be powered
from an uninterruptible power supply (UPS) or
a battery.

Portable and mobile RF communications equipment
should be used no closer to any part of the VisionAire
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance

D= 1.2 x
√P from 80MHz to 800MHz
D= 2.3 x √P from 800MHz to 2.5GHz
where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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.
a. 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 VisionAire is used exceeds the applicable RF
compliance level above, the VisionAire should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the VisionAire.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
