Guidance and manufacturer's declaration -
electromagnetic immunity
Table 204
The UD-6000 is intended for use in the electromagnetic environment specified below. The customer or
the user of the UD-6000 should assure that it is used in such an environment.
Electromagnetic environment -guidance Immunity test IEC 60601 test
level Compliance
level
Portable and mobile RF communication
equipment should be used no closer to any part
of the
UD-6000 , including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d =1.2 P
d =1.2
80 MHz to 800 MHz
d =2.3
800 MHz to 2.5 GHz
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:
Conducted RF
IEC 61000-4-6 3 V rms
150kHz to 80MHz 3 Vrms
Note1: 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.
Radiated RF
IEC 61000-4-3 3 V/m
80MHz to 2,5GHz 3 V/m
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
UD-6000 is used exceeds the applicable RF compliance level above, the UD-6000 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the
UD-6000 .
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
