The N-600x is suitable for use in the specified electromagnetic environment. The
customer and/or user of the N-600x should assure that it is used in an electromagnetic
environment as described below.
Immunity IEC 60601-1-2
Test Test Level
Power frequency 3 A/m
(50/60 Hz)
magnetic field
IEC 61000-4-8
Note: U is the AC mains voltage prior to application of the test level.

Table 18: Electromagnetic Immunity, RF Portable Equipment
The N-600x is suitable for use in the specified electromagnetic environment. The
customer and/or user of the N-600x should assure that it is used in an electromagnetic
environment as described below:
Immunity IEC 60601-1-2
Test Test Level
Portable and mobile RF communications equipment should be used no closer to any
part of the N-600x, including cables, than the recommended separation distance
calculated from the equation appropriate for the frequency of the transmitter.
Note: 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 survey
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 N-600x is used exceeds the applicable
RF compliance level above, the N-600x should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the N-600x.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
Interference may occur in the vicinity of equipment marked with the following symbol:

it may be necessary to
position the N-600x further
from the sources of power
frequency magnetic fields
or to install magnetic
shielding. The power
frequency magnetic field
should be measured in the
intended installation
location to assure that it is
sufficiently low.
