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
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz
800 MHz
3 V/m
800 MHz
2.5 GHz
Conducted RF 3 Vrms
IEC 150 kHz
61000-4-6
80 MHz
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:
