Guidance And Manufacturer's Declaration - Electromagnetic Immunity - NOMICS BRIZZY NS21 Manuel D'utilisation

Guidance and manufacturer's declaration – electromagnetic immunity
BRIZZY is intended for use in the electromagnetic environment specified below. The customer or the user
of BRIZZY should assure that it is used in such an environment.
Immunity test
Conducted
RF CEI 61000-4-6
Radiated RF
CEI 61000-4-3
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
BRIZZY is used exceeds the applicable RF compliance level above, BRIZZY should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating BRIZZY.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
level
Portable and mobile RF communications
equipment should be used no closer to any part
of BRIZZY, including cables, than the recom-
mended separation distance calculated from
the equation applicable to the frequency of the
transmitter. Recommended separation distance
d =1,2√P
d =1,2√P 80 MHz to 800 MHz
d =2,3√P de 800 MHz to 2,5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended 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 equip-
ment marked with the following symbol:
