Compliance to the Electromagnetic Immunity (2)
The LX-7230N is intended for use in the electromagnetic environment
specified below. The customer or the user of the LX-7230N should assure that
it is used in such an environment.

Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of the
LX-7230N, including cables, than
the recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended Separation Distance
Conducted RF
IEC 61000-4-6
3Vrms
150kHz to 80MHz

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 80MHz and 800MHz, 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 LX-7230N is used exceeds the applicable RF compliance
level above, the LX-7230N should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the LX-7230N.
b)
Over the frequency range 150kHz to 80MHz, field strength should be less than
3V/m.
