Guidance and manufacturer's declaration - electromagnetic immunity
The 28075 / NB-810B is intended for use in the electromagnetic environment
specified below. The customer or the user of the 28075 / NB-810B should
assure that it is used in such an environment.
IMMUNITY test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 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 the 28075 / NB-810B
is used exceeds the applicable RF compliance level above, the 28075 / NB-810B should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the 28075 / NB-810B.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

be used no closer to any part of the
28075 / NB-810B, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the

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
