Electromagnetic Immunity
imagiQ2 is intended for use in the electromagnetic environment specified below.
The customer or the user of the imagiQ2 should assure that it is used in such an environment.

Electromagnetic environment- guidance
Portable and mobile RF communications equipment should be used no
closer to any part of imagiQ2, including cables, than the recommended
separation distance calculated from the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80
MHz
10 V
d= [0,58]√P
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2,5
GHz
10V/m
d= [0,35]√P 80 MHz to 800 MHz
d= [0,7]√P 800 MHz to 2,5 GHz
Where P is the maximum output rating of the transmitter in watts (W)
according to the transmitter manufacturer and d is the recommended
separation distance in metres (m).
Field strength from fixed RF transmitters, as determined by an electro-
magnetic 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 fol-
lowing symbol:
Note 1 At 80MHz and 800 MHz, the higher frequency range applies.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagations are affected by absorption and reflection from struc-
tures, objects and people.
a Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, armature
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which imagiQ2 is used exceeds the applicable RF compliance level above, imagiQ2 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating imagiQ2.
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 10 V/m.
WARNING: Using other cables and accessories than the specified, can possibly increase the emission and
decrease the immunity in regards of EMC requirement.
