VisionAire™
Guidance and manufacturer's declaration ± electromagnetic immunity
The VisionAire is intended for use in the electromagnetic environment specified below. The customer or the user of the
VisionAire should assure that it is used in such an electromagnetic environment.
IMMUNITY test IEC 60601 TEST LEVEL
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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.
MN137-1 rev. H
Compliance level
3 Vrms 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
3 V/m the frequency of the transmitter.
Recommended separation distance
D= 1.2 x √P
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
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
