Guidance and manufacturer’s declaration - electromagnetic immunity
the [Kn-520] is intended for use in the electromagnetic environment
specified below. the customer or the user of the [Kn-520] should assure
that it is used in such an environment.

portable and mobile rf
communications equipment should
be used no closer to any part of the
[Kn-520], including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency
of the transmitter.
recommended separation distance:
Compliance
level
3 Vrms
3 V/m
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, a
should be less than the compliance
level in each frequency range. b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
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 [Kn-520] is used exceeds
the applicable rf compliance level above, the [Kn-520] should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the [Kn-520].
b
over the frequency range 150 kHz to 80 mHz, field strengths should be less than 3V/m.
