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

Electromagnetic Environment
Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of the
LX-7230, 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 3Vrms
d
= 1.2
P
Radiated RF
IEC 61000-4-3 3V/m
80MHz to 2.5GHz 3V/m
d
= 1.2
P
80MHz to 800MHz
d
= 2.3
P
800MHz to 2.5GHz
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-7230 is used exceeds the applicable RF compliance
level above, the LX-7230 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-7230.
b)
Over the frequency range 150kHz to 80MHz, field strength should be less than
3V/m.
