Guidance and manufacture’s declaration – electromagnetic immunity
The HX-400 is intended for use in the electromagnetic environment specified below. The
customer or the user of the HX-400 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
HX-400, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
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 metres (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 HX-400 is used exceeds the
applicable RF compliance level above, the HX-400 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the HX-400.
b Over the frequency range 0.15Hz to 80 MHz, field strengths should be less than 3 V/m.
