GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The Invitium System is intended for use in the electromagnetic environment specified below.The
customer or the user of the Invitium System should assure that it is used in such an environment.

ENVIRONMENT - GUIDANCE
Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the Invitium
System, including cables, than the rec-
ommended separation distance calcu-
lated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.16 eP
d = 1.16 eP 80 MHz to 800 MHz
d = 2.33 eP 800 MHZ to 2.5 GHz
where P is the maximum output
power rating of the transmitter in watts
(W) according to the transmitter man-
ufacturer and d is the recommend sep-
aration distance in meters (m).
Field strengths from fixed RF trans-
mitters, as determined by an electro-
magnetic site survey,
a
should be less
than the compliance level in each fre-
quency range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 Vrms
150 KHz to 80

3 V/m
80 MHz to 2.5
GHz
3 Vrms
3 V/m
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propogation 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 Invitium System is used exceeds the applicable RF compliance level above, the
Invitium System should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Invitium System.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
